Brain and Spine Injury Law Blog : Brain and Spine Injury Lawyer & Attorney : Tim Titolo Law Office : Personal Injury & Wrongful Death : Car, Truck, and Motorcycle Accident: Las Vegas, Nevada

 We are almost through August and more than half way through Summer 2010. Parents, children and kids are preparing for the return to school in the next couple of weeks. In Nevada, public schools start August 30.

Meanwhile Nevada, and particularly Las Vegas, continues to muddle through the recession which for Southern Nevada has been a novel experience. The unemployment rate is close to 15% as I write.  The city many thought was immune from economic storms has seen itself hardest hit. Hopefully things will improve.

We face a heated election where the Tea Party candidate, Sharon Angle, accuses Democrat incumbent, Harry Reid, for the current state of plummeted home values while Reid criticizes Angle for not making job creation a part of her job!

The Station Casino’s recent resurface from Bankruptcy with owners, Frank and Lorenzo Fertitta, manning the helm, may be a boost. Of course some creditors had to write off $4,000,000,000 – four billion dollars! But maybe the massive adjustment will re establish the local casino group and have a positive impact on Las Vegas. 

Today’s report of the M Resort, opening just over a year ago, being put up for sale may result in an interesting bid; especially if Boyd gets back into the picture. Boyd’s recent failed effort to take over Station properties may be a prelude to an M resort bid.  Although my sources tell me that Station may make a bid to buy M resort now that they have shaken off 4 billion in debt.

I am reporting on 2 separate topics relating to Brain and Spine Injury issues. First is a look at the Cleveland Clinic’s Las Vegas Lou Ruvo Center. Second is the recent revelation concerning veterans. 

Lou Ruvo Brain Center

Nevada, and specifically Las Vegas, may be on its way to becoming the "go-to" place in the country for Brain Health.  The Cleveland Clinic Lou Ruvo Center for Brain Health (CCLRCBH) provides state-of-the-art care for cognitive disorders and for the family members of those who suffer from them.

 For persons with mild cognitive impairment such as early stage dementia and Alzheimer’s disease, the center offers the most up-to-date and technologically advanced diagnostic imaging services, including 3-Tesla MR, performed by one of the leading neuroimaging academic centers in the world. The CCLRCBH also offers a multimodal treatment program for persons with mild cognitive disorders, including physical exercise, cognitive rehabilitation, and cognitive enhancing medications.

Recently named to head up the Center, leading researcher and neurologist Jeffery L. Cummings, MD, will be the Director of the Cleveland Clinic Lou Ruvo Center for Brain Health.

Prior to joining Cleveland Clinic, Dr. Cummings was the director of the Mary S. Easton Center for Alzheimer’s Disease Research and a professor of Neurology and Psychiatry and Biobehavioral Sciences at David Geffen School of Medicine at UCLA.

He is past president of the Behavioral Neurology Society and of the American Neuropsychiatric Association. Dr. Cummings has authored or edited 30 books and published more than 600 peer-reviewed papers.
 

Misdiagnosis Hurt U.S. Soldiers

We now know that during the height of the Iraq war, the Army routinely misdiagnosed hundreds of soldiers with “personality disorder.” In doing this, the Army was categorizing veterans being dismissed from duty, with a pre-existing condition. Pre existing conditions are not covered by the military health care for veterans.

Leaving wounded veterans ineligible for military health care and with a stigma attached to mental weakness, advocates for veterans, congress and the public actively pushed for re-evaluation of veterans conditions. The Nation, published an article exposing the practice and caused the Defense Department to change its policy. 

All soldiers diagnosed with Personality disorder prior to 2008 are being re-evaluated. Before 2008, over 1000 soldiers were dismissed based on personality disorder. In 2009 only 260 were dismissed for personality disorder.   By 2008, 14,000 soldiers were diagnosed with brain injury or post traumatic stress disorder.   The number of personality disorder cases dropped 75%. Watch this You Tube video.

The significance for those men and women that serve the country in the military is staggering. Could you imagine sacrificing life and limb only to have the U.S. government tell you that you suffered a pre-existing personality disorder? Why, you might ask, did the Army, for example, not make that determination until after my sacrifice of life and limb? How convenient for the Army to take advantage of the sacrifice and not pay the veteran when they can no longer make the sacrifice.

We now know about PTSD as it relates to war, something the Vietnam veterans did not benefit from. We also know, unlike Vietnam, that more soldiers stay alive after blast and concussion trauma due to the enhanced protective gear.

I really hope that the U.S. will be proactive in caring for its military. I think we should all support brain injury groups like the Brain Injury Association of America who are on the front lines, so to speak, in getting legislation for brain injured survivors.

You may not want to miss this.  ABC News announces a new primetime series, “Nightline Prime,” which premieres Thursday, August 19 examining the mystery and science of the brain.

Each installment will focus on a different research areas, including emotion's impact on the brain, medical emergencies involving the brain, violence and the brain, and food and the brain.

The four installments of Secrets of Your Mind begin airing Thursday, August 19 at 10:00pm ET/PT and continue on the three subsequent Thursdays:
Here is a rundown of each of the shows:

 Thursday, August 19: “Nightline” co-anchor Cynthia McFadden explores the brain in love. She follows a remarkable story of love lost and found again after a traumatic brain injury. McFadden also talks to a man who is literally paralyzed by love—a peculiar brain condition that causes his body to shut down when he experiences feelings of love for his wife.

Thursday, August 26: Martin Bashir takes a journey inside the mind of a psychopath. Bashir examines evil’s origin in the brain and whether people can be born with a tendency for evil or violent behavior and if it can be detected in childhood. In his reporting, Bashir visits death row for a close-up look at two of the country’s most notorious serial killers. He also speaks exclusively to the distraught father of Chris Benoit, the pro-wrestler who murdered his family then himself.

 Thursday, September 2: “Nightline” co-anchor Terry Moran embeds with Dr. Bailes for a first-hand look at life-and-death drama inside the operating room. It’s a race against time as cameras capture an aneurism bursting on the operating table and Dr. Bailes and his team have only seconds to react.

Read this article featured in Discover about Lou Gehrig and the disease that bears his name:

That may seem a strange question, akin to asking who’s buried in Grant’s tomb. But a new study proposes that some athletes diagnosed with Lou Gehrig’s disease may in fact have a different fatal disease that is set off by concussions.

Researchers have previously investigated the link between athletes and this neurodegenerative disease, more technically known as amyotrophic lateral sclerosis (ALS). A recent study examined what seemed to be a higher than usual incidence of Lou Gehrig’s disease among soccer players, and, of course, the disease bears the name of a New York Yankee who was famously undaunted by the hard knocks of his sport. Though it’s impossible to determine now whether Lou Gehrig suffered from ALS or a different condition (Gehrig was cremated), the study’s lead author speculates that Lou Gehrig’s disease might be a misnomer:

A recent study was funded by the National Institute of Mental Health entitled "Stigma Experience Among Adolescents Taking Psychiatric Medications."  This breaks open the issue of stigma in patients treated for mental illness as it applies to teenagers.

Teenagers reimagine the way people think about adolescents. No longer society's scourge and scapegoat, the teenager emerges from David Bainbridge's fascinating study as an awe-inspiring natural phenomenon that evokes reverence and wonder. Bainbridge, an anatomist, suggests that the second decade is the most important in the human lifecycle. In lively prose, he explains the science behind the changes that occur both on the surface of the teenage body and deep within the teenage brain, from lanky limbs and bad skin to falling in love, sleeping till noon, and the irresistible allure of sex, drugs, and rock‘n’roll. Observed through a scientific lens, these bizarre biological transformations and behavioral anomalies snap into focus, as not only a beautifully choreographed sequence of steps on the path to adulthood, but also as a key evolutionary factor in the success of the species.

Teenagers have their own special place in the study of development and brain science. 

The study evaluated boys and girls between the ages of 12 and 17 who are taking medications. Researchers found that at least 90 percent of the study's participants reported experiencing some form of stigma. It has led to shame, secrecy and limiting social interactions.

While the stigma associated with wounded veterans, soldiers and adults is relatively known, this data suggests young people are burdened as well.  Individuals, young and old, with mental illnesses suffer from public and self-stigmas. The researchers were concerned about how the youth internalized the public discrimination, or stereotyping of their illnesses, and if these stigmas experienced at a young age might impact the individuals as adults.

1 in 6 adults and almost 1 in 10 children suffer from a diagnosable mental illness. Yet, for many, the stigma associated with the illness, can be as great a challenge as the disease itself. This is where the misconceptions stop. This is where bias comes to an end.

Here are some interesting Fact versus Fiction data I found on the internet. 

FICTION: People with a mental illness are often violent.

 FACT: Actually, the vast majority of people with mental health conditions are no more violent than anyone else. People with mental illness are much more likely to be the victims of crime.

 FICTION: Mental illness is a sign of weakness.

 FACT: A mental illness is not caused by personal weakness—nor can it be cured by positive thinking or willpower - proper treatment is needed.

 FICTION: Only military personnel who have been in combat can suffer from PTSD.

 FACT: While PTSD is prevalent in men and women who have seen combat, experiencing or witnessing a traumatic event can trigger PTSD, including violent personal assaults such as rape or robbery, natural or human-caused disasters, or accidents.

 FICTION: People with a mental illness will never get better.

 FACT: For some people, a mental illness may be a lifelong condition, like diabetes. But as with diabetes, proper treatment enables many people with a mental illness to lead fulfilling and productive lives.

 FICTION: Children don’t suffer from mental illness.

 FACT: Millions of children are affected by depression, anxiety and other mental illnesses. As a matter of fact, 1 in 10 children suffer from a diagnosable mental illness. Getting treatment is essential.

 FICTION: “Mental illness can’t affect me!”

 FACT: Mental illness can affect anyone. While some illnesses have a genetic risk, mental illness can affect people of all ages, races and income levels, whether or not there is a family history. 

I also ran across a cool blog on Facebook called bringchange2mind. Check it out.

A new classification of depressive subtypes of depression has been proposed in the current issue of Psychotherapy and Psychosomatics.  In keeping current on the new DSM being revised, as I have been writing about in previous posts, certain authors are recommending a revamping of depression subtypes to effect treatment. 

Lichtenberg and Belmaker argue that a simple diagnosis is no longer sufficient to guide treatment.  They propose the following subtypes:

Type A: Depression with Anxiety

Type B: Acute Depression

Type C: Adult Depression after Childhood Trauma

Type D: Depressive Reaction to Separation Stress

Type E: Postpartum Depression

Type F: Late-Life Depression

Type G: Psychotic Depression

Type H: Atypical Depression

Type I: Bipolar Depression

Type J: Depression Secondary to Substance Abuse or to a Medical Condition.

 One of the major challenges in treatment of depression seems to be the heterogeneity of the disorder. It is not uncommon to see significant differences in symptomatic presentation of depress patients.  Besides there are differences in age of onset, severity of course, treatment response and comorbid conditions. One assumption is that the heterogeneity is simply because there are different subtypes of depression,

says Tanvir Singh, MD and Alina Rais, MD, Dept. Psychiatry, University of Toledo Medical Center in their article entitled Subtypes of Depression.

I will anxiously await more information on the revised DSM.  For more information visit www.depression.com.

New Evidence that prevention will not cure Alzheimer's.  Here is some news that will turn your head around.  Just when you thought you might be doing everything right, you find out you might be wrong.  This reminds me of how much cigarette smoking is condoned Europe.  If you have ever been on an elevator in Italy or France you can not help but notice (and ingest) second hand smoke from the habitual smokers.  Now why is that?  Did Woody Allen's prediction in Sleeper come true?  Are cigarettes really good for you!?  And now the following.

An independent panel of experts meeting in the US concluded there is no evidence that you can prevent or slow down Alzheimer's, a progressive and fatal brain disease, even if you keep yourself active with exercise, social interaction, brain puzzles, or take fish oil, other supplements, or medication.  That is exactly the opposite of what we have been told.

The National Institutes of Health determined that the value of these strategies for delaying the onset and/or reducing the severity of decline or disease hasn't been demonstrated in rigorous studies.  Interestingly, the panel's assessment of the available evidence revealed that progress to understand how the onset of these conditions might be delayed or prevented is limited by inconsistent definitions of what constitutes Alzheimer's disease and cognitive decline. Other factors include incomplete understanding of the natural history of the disease and limited understanding of the aging process in general. The panel recommended that the research community and clinicians collaborate to develop, test, and uniformly adopt objective measures of baseline cognitive function and changes over time.
 

Alzheimer's Disease and Cognitive Decline, Structured Abstract. April 2010. Agency for Healthcare Research and Quality, Rockville, MD. http://www.ahrq.gov/clinic/tp/alzcogtp.htm actually concludes:

The current research on the list of putative risk or protective factors is largely inadequate to confidently assess their association with AD or cognitive decline. Further research that addresses the limitations of existing studies is needed prior to be able to make recommendations on interventions.

 But the initial ramifications may make us all rethink taking up smoking!  If you have not seen it, watch Woody Allen explain it in this short video.

What is Inteligent Design and What is Random?  I recently came across a statement by Wasserman and Blumberg in the May-June issue of American Scientist that I want to share.

Do not take this too seriously...or do.

Although evolutionists and creationists strongly disagree about the role that intelligent design plays in the origins of bodies and brains, they curiously agree about the role that intelligent design plays in the origins of human inventiveness. However, both camps would do well to focus less on perceived foresight and purpose and more on the actual origins of behavior.

Contemporary evolutionists such as Richard Dawkins should move beyond the arcane argument over where to draw the line between things that "really are designed" and "things that only appear to be designed." By doing so, Wasserman and Blumber note, we will better appreciate the actual forces that unite the processes of change across both evolutionary and developmental timescales.
And that I like:  appreciating the actual forces that unite the processes of change across both evolutionary and developmental timescales.  Is your language science?  Is it theology or philosophy?  Do you call it God, Jesus, Mohammad, or simply "the force?"  I believe something is there, what ever you want to call it.

Interestingly, devices similar to pacemakers that regulate blood flow through heart control, promote good neuropsychological health.  A March 2010 study confirms.

A standard test of the implantable cardioverter defibrillator (ICD) is linked to significant thought-processing problems that improve for most patients within a year after the device is inserted, according to research reported in Circulation: Arrhythmia and Electrophysiology, a journal of the American Heart Association.

 Conclusions—ICD implantation is associated with neuropsychological impairment which dissipates for the majority of recipients after 12 months. Short-term memory function and attention are particularly vulnerable to changes in oxygen during ICD testing. Although, anxiety and depression are prevalent, there is little evidence for the direct impact of mood on cognition, and deficits appear not to be associated with reduced quality of life. These results provide evidence for longitudinal outcomes of ICD surgery and have implications for patient rehabilitation and adjustment.

Have religious leaders and prophets, been able to tap into something science has not?  A recent grant will finance a study on the science of free will.  Are we predestined to live the blueprint of life already created for each of us?  Do we control our own destiny?  Or is it something beyond our comprehension?  Is our free will and control of destiny something foreordained toward a result that we will inevitably reach?

Since the beginning of time, philosophers, scientists and theologians have sought to find out whether human beings have free will or whether other forces are at work to control our actions, decisions and choices.

Now, Florida State University philosopher Alfred Mele has been awarded a $4.4 million grant from the John Templeton Foundation to get to the bottom of this question for the ages. Mele, the William H. and Lucyle Werkmeister Professor of Philosophy, will oversee a four-year project to improve understanding of free will in philosophy, religion and science. 

The primary purpose of the project is to improve understanding of free will in three spheres: science (especially neuroscience and social psychology); philosophy; and theology.  The project's website can be accessed here.

I previously posted in this blog about the new revelations of free will.  In fact, in 2008, Professor John-Dylan Haynes and colleagues at the Max Planck Institute in Germany reported findings of an extraordinary experiment which seems to show that 'free will' -- the most cherished tenet of humanity, which decrees that Man has total control of his own actions -- may, in fact, be little more than an illusion.

Since I recently posted on the topic linking high blood pressure to dementia, I came across my doctor's newsletter on Blood Pressure.  I reprint it here for those interested.

The leading cause of death and disability in the United States is from cardiovascular diseases, and the most common disease is high blood pressure.  High blood pressure, also known as
hypertension, usually does not have any symptoms – hence, the nickname “silent killer.”

Unfortunately, one-third of those who have high blood pressure do not realize it and are not aware of their risk for heart disease. Therefore, many people live years without treatment, possibly damaging their heart, blood vessels, and kidneys.

Lifestyle choices (e.g., weight control, tobacco use, proper nutrition, regular exercise) can help
prevent and/or control high blood pressure. The following are common questions and answers about blood pressure.

What is blood pressure?

It is the force of blood against the walls of arteries. Systolic pressure (the top number) is the force as the heart beats. Diastolic pressure (the bottom number) is the force as the heart relaxes.

A blood pressure reading of 120/80 mmHg is articulated as “120 over 80.”

What is the meaning of the numbers?

A systolic pressure of 120 or less is considered normal. Diastolic pressure of 80 or less is considered normal. Therefore, 120/80 or less is a normal blood pressure. The chart below shows normal blood pressure levels, as well as the levels of high blood pressure.

What are the dangers of high blood pressure?

High blood pressure places an additional strain on the circulatory system (i.e., heart and blood vessels).  This strain results in arteries becoming thicker, narrower, and weaker, sometimes causing an obstruction.  A completely obstructed artery often leads to heart attacks, strokes, kidney disease, and dementia.

Is low blood pressure a health problem?

The training effect of regular exercise, especially when working out rigorously, is a lower blood pressure. At times, an individual who does not exercise may experience regular low blood pressure. If symptoms do not accompany the low pressure, it usually is not serious. However, if
blood pressure suddenly drops, it may indicate an underlying problem causing inadequate blood flow to the heart, brain, and other vital organs. Symptoms may include dizziness or lightheadedness.

What are some tips to prevent/control high blood pressure?

Healthy living is at the heart of preventing and controlling high blood pressure. Are you:
 Maintaining a healthy weight?
 Engaging in regular physical activity (fi ve 30-minute sessions of aerobic exercise and two
30-minute strength training sessions per week)?
 Eating a low-fat, high-nutrient diet (fruits, vegetables, low-fat dairy foods, low sodium)?
 Limiting alcohol consumption?

 Another study has found that hypertension may contribute to increased risk of dementia, this time with evidence of actual brain abnormalities. I previously wrote about the link between Hypertension and Alzheimer's disease.

This is especially relevant to those who are not controlling their blood pressure. Blood pressure is not something one feels is high or low. Specific medical evaluation, blood pressure test, is necessary. 

Data from an offshoot of the Women's Health Initiative found that participants' baseline blood pressure was strongly correlated with volume of lesions in their brains' white matter, according to Lewis Kuller, MD, DrPH, of the University of Pittsburgh, and colleagues.

Along with earlier studies linking blood pressure to clinical dementia, the evidence "supports tight control of blood pressure levels, especially beginning at younger and middle age as a possible and perhaps only way to prevent dementia," Kuller and colleagues concluded online in the Journal of Clinical Hypertension.

Treating hypertension in the elderly appears to protect against dementia and cognitive decline.  Uncontrolled hypertension in older patients increases the risk of cognitive impairment. Hypertensive patients had a 70% greater risk of non-amnestic mild cognitive impairment compared with nonhypertensive patients according to Christiane Reitz, M.D., Ph.D., of Columbia University in New York. (C Reitz et al. "Hypertension and the risk of mild cognitive impairment." International Society of Vascular Behavioral and Cognitive Disorders meeting, July 11-14, San Antonio. Final program and abstract book. Abstract O-6)

For each year an individual took medication to lower blood pressure, the risk of dementia decreased by about 3%, found Rita Peila, Ph.D., an epidemiologist at the National Institute on Aging and a scientist at the Pacific Health Research Institute in Honolulu.

My question is whether a person who controls their blood pressure and hypertension with medicine can decrease their risk of dementia to that of someone without hypertension.  I predict that other risk factors would need to be accounted for but, other things being equal, can a person with controlled high blood pressure eliminate the risk of dementia?

Findings published in Nature Neuroscience help explain why light makes Migraine Headaches worse. 

Ask anyone who suffers from migraine headaches what they do when they're having an attack, and you're likely to hear "go into a dark room." And although it's long been known that light makes migraines worse, the reason why has been unclear. 

Migraine is a recurring, episodic neurological disorder characterized as throbbing headache that is commonly associated with a variety of other symptoms (for example, nausea, vomiting, irritability and fatigue).  Migraines are chronic headaches that can cause significant pain for hours or even days. Symptoms can be so severe that all you can think about is finding a dark, quiet place to lie down.

For light to make pain worse, the pathways have to converge somewhere, thought the researchers at Beth Israel Deaconess Medical Center.  Exacerbation of migraine headache by light is prevalent among blind individuals. Light can increase the electrical activity in neurons.

One expert said these findings should put to rest any suggestion that patients exaggerate their sensitivity to light; they are not whining or imagining their symptoms.

"A neural mechanism for exacerbation of headache by light."

People often confuse coma as being necessary for brain injury to occur.  This is far from the facts or truth.  However coma usually confirms that brain injury has, in all probability, robbed the individual of cognition or motor function.  Only rarely does one recover completely from coma.

I thought a refresher on what Coma and Glasgow Coma Scale are would be helpful.

A coma, or being comatose, is a deep state of unconsciousness - longer-term comatose patients may be reclassified as being in a permanent vegetative state. Recall Terry Schiavo. The patient cannot be awakened and does not respond to pain, light or sound in a normal way - the person in coma cannot react with the surrounding environment. A person in a coma does not take voluntary actions and does not have sleep-wake cycles.

The inability to waken differentiates coma from sleep. Levels of unconsciousness and unresponsiveness vary, depending on how much of the brain is functioning.  Neurological Experts and family often argue about whether the comatose patient can hear voices or perceive events or the presence of people. 

Coma may occur for various reasons, such as intoxication, CNS (central nervous system) diseases, a traumatic injury, and hypoxia (oxygen deprivation). Coma can be induced deliberately with pharmaceutical agents - perhaps in order to protect the patient from intense pain during a healing process, or to preserve higher brain function following another form of brain trauma.

Comas generally do not last for more than a few weeks. A patient whose state does not change after an extended period is often reclassified as being in a persistent vegetative state. Unfortunately, those in a persistent vegetative state for over twelve months rarely wake up.

Another condition is known as "Locked-In Syndrome."  Locked-in syndrome is a rare neurological disorder characterized by complete paralysis of voluntary muscles in all parts of the body except for those that control eye movement. It may result from traumatic brain injury, diseases of the circulatory system, diseases that destroy the myelin sheath surrounding nerve cells, or medication overdose. Individuals with locked-in syndrome are conscious and can think and reason, but are unable to speak or move. The disorder leaves individuals completely mute and paralyzed. Communication may be possible with blinking eye movements

A book and movie called "The Butterfly and Diving Bell" was written by Jean-Dominique Bauby who could only move his eyelid.  Through the help of an interpreter, he wrote the entire book, letter by letter, by moving his eyelid when the letter was identified.
 

What are the possible causes of a coma?

A coma can have several possible causes, including:

• Diabetes - if the blood sugar levels of the diabetes patient rise too much they will have hyperglycemia, the opposite is hypoglycemia (blood sugar levels are too low). Sustained periods of hyperglycemia or hypoglycemia can result in coma.
   
• Hypoxia (lack of oxygen) - a person who nearly drowned may not awaken because of a shortage of blood (which carries oxygen) to the brain. The same may occur to somebody who is resuscitated after a heart attack.
   
• Infections - those which cause inflammation of the brain, spinal cord or tissues surrounded the brain can result in coma if symptoms are severe enough. Examples include encephalitis or meningitis.
   
• Stroke - a condition where a blood clot or ruptured artery or blood vessel interrupts blood flow to an area of the brain. A lack of oxygen and glucose (sugar) flowing to the brain leads to the death of brain cells and brain damage, often resulting in impairment in speech, movement, and memory - and sometimes coma.
   
• Toxins and drug overdoses - exposure to carbon monoxide can result in brain damage and coma, as can some drug overdoses.
   
• Traumatic brain injuries - these include injuries from vehicle accidents and violent attacks. They are the most common cause of comas.

Diagnostic Tools

Lumbar puncture (spinal tap) - this can determine whether there is an infection. The doctor inserts a needle into the patient's spinal canal, measures pressure and extracts fluid.   Ruling out meningitis usually utilizes spinal tap.

Imaging scans of the brain - these will help determine whether there is any brain injury/damage, and where. Examples include:

• CT (computed tomography) scan - also known as a CAT (Computer Axial Tomography) scan. It is a medical imaging method that employs tomography. Tomography is the process of generating a two-dimensional image of a slice or section through a 3-dimensional object (a tomogram). The medical device is called a CTG scanner; it is a large machine and uses X-rays. It used to be called an EMI scan, because it was developed by the company EMI.
   
• MRI (magnetic resonance imaging) scan - an MRI machine uses a magnetic field and radio waves to create detailed images of the body, which in this case would be the brain. Most MRI machines look like a long tube, with a large magnet present in the circular area. When beginning the process of taking an MRI, the patient is laid down on a table. Then depending on where the MRI needs to be taken, the technician slides a coil to the specific area being imaged. The coil is the part of the machine that receives the MR signal. MRI scans are good for examining the brainstem and deep brain structures. The doctor may inject a special dye which shows up on the scans and distinguishes healthy tissue from damaged tissue. 
   
• EEG (electroencephalography) - the device measures the electrical activity within the brain. Electrodes are placed on the patient's scalp; they pick up electrical impulses that occur in the brain. These impulses are recorded on the EEG device. An EEG can tell whether the patient is having non-convulsive seizures. 
•  
• PET (Positron Emission Tomography) - a nuclear medicine imaging technique which produces a three-dimensional image or picture of functional processes in the body. The system detects pairs of gamma rays emitted indirectly by a positron-emitting radionuclide (tracer), which is introduced into the body on a biologically active molecule. Images of tracer concentration in 3-dimensional space within the body are then reconstructed by computer analysis.

 Glasgow Coma Scale (GCS)

This scale is very useful for determining conciousness in severe cases.  Unfortunately it is fequently misused in cases of mild and moderate traumatic brain.  For instance, Mild Traumatic Brain Injury, which many times has devasting consequences, is defined by the same value on GCS as for a completely normal individual.  Hence those with incentive to discredit the reality of brain injury point to the "normal" GCS.

The GCS scores patients according to verbal responses, motor responses (physical reflexes), and how easily they can open their eyes.

• Eyes - Glasgow Coma Scale
  
  Score of 1 - does not open eyes.
  Score of 2 - opens eyes in response to painful stimuli (when given pain).
  Score of 3 - opens eyes in response to voice.
  Score of 4 - opens eyes spontaneously.
  
  
   
• Verbal - Glasgow Coma Scale
  
  Score of 1 - makes no sound.
  Score of 2 - incomprehensible sounds (mumbles).
  Score of 3 - utters inappropriate words.
  Score of 4 - confused, disorientated.
  Score of 5 - oriented, chats normally.
  
   
• Motor (physical reflexes) - Glasgow Coma Scale
  
  Score of 1 - makes no movements.
  Score of 2 - extension to painful stimuli (straightens limb when given pain).
  Score of 3 - abnormal flexion to painful stimuli (moves in a strange way when given pain).
  Score of 4 - flexion/withdrawal to painful stimuli (moves away when given pain).
  Score of 5 - localizes painful stimuli (can pinpoint where pain is).
  Score of 6 - obeys commands.
  
  
   
• Brain injury will be classified in the Glasgow Coma Scale as:
  
  Coma = a score of 8 or less.
  Moderate = a score of 9 to 12.
  Minor = a score of 13 or more.

Size is not what counts in the hunt for the most intelligent.  Whales have brains weighing 9 kg (with over 200 billion nerve cells), and human brains vary between 1.25 kg and 1.45 kg (with an estimated 85 billion nerve cells). A honeybee's brain weighs only 1 milligram and contains fewer than a million nerve cells. 
 

Insects may have tiny brains, but they can perform some seriously impressive feats of mental gymnastics.

According to a growing number of studies, some insects can count, categorize objects, even recognize human faces -- all with brains the size of pinheads.

WATCH VIDEO: Take a closer look at the lives of mosquitoes, maggots and other creepy crawlies.

Despite many attempts to link the volume of an animal's brain with the depth of its intelligence, scientists now propose that it's the complexity of connections between brain cells that matters most. Studying those connections -- a more manageable task in a little brain than in a big one -- could help researchers understand how bigger brains, including those of humans, work.

Scientists at Queen Mary, University of London, state that contrary to popular belief, we can't say that brain size predicts the capacity for intelligent behavior.

Research repeatedly shows how insects are capable of some intelligent behaviors scientists previously thought were unique to larger animals.

Research suggests that bigger animals may need bigger brains simply because there is more to control - for example they need to move bigger muscles and therefore need more and bigger nerves to move them.

A presentation by the American Heart Association's (AHA) annual Scientific Sessions in Orlando revealed the pooling results from 21 studies, involving 622,381 men and women, to conclude that the risk of stroke for those with migraines is 2.3 times those without.

Researchers at Johns Hopkins have affirmed that migraine headaches are associated with more than twofold higher chances of the most common kind of stroke: those occurring when blood supply to the brain is suddenly cut off by the buildup of plaque or a blood clot.

Here is a good one for all us musicians...

Regularly playing a musical instrument changes the anatomy and function of the brain and may be used in therapy to improve cognitive skills.

There is growing evidence that musicians have structurally and functionally different brains compared with non-musicians. In particular, the areas of the brain used to process music are larger or more active in musicians. Even just starting to learn a musical instrument can changes the neurophysiology of the brain.

Lutz Jäncke, a member of Faculty of 1000 Medicine, proposes using music in neuropsychological therapy, for example to improve language skills, memory, or mood. In a review for Faculty of 1000 Biology Reports, an online publication in which leading researchers highlight advances in their field, Jäncke summarizes recent studies of professional musicians

Traumatic Brain Injury many times produces feelings of fatigue.  The theory is that since the brain needs to work harder after trauma to compensate for interrupted neural pathways, a feeling of tiredness results.  To make matter worse, that tiredness is also accompanied, many times by insomnia.  TBI sufferers are usually tired due to the hyper activity required to maintain previous function in addition to insomnia.

The American Academy of Sleep Medicine defines insomnia as unsatisfactory sleep that impacts daytime functioning. More than one third of adults report some degree of insomnia within any given year, and 2 to 6 percent use medications to aid sleep. Insomnia is associated with increased morbidity and mortality caused by cardiovascular disease and psychiatric disorders and has other major public health and social consequences, such as accidents and absenteeism.

I recently posted the article entitled "10 Brainiest Cities."  To follow up the other end of the scale I now post an article by the same reporter revealing the 10 Lowest Cities.

Zach Miners, U.S. News & World Report

Not every state in the union can be full of geniuses, right? At least that's what, at first glance, one might conclude after seeing the results of the "life'sDHA Index of Brain Health," an assessment that ranks all 50 states and the District of Columbia according to what its creators consider to be factors supporting brain health.

Washington, D.C., and nine brain-healthy states made the top 10 list. Here are the 10 lowest-ranking states: Indiana, North Dakota, South Carolina, Arkansas, Kentucky, Tennessee, Mississippi, Alabama, Oklahoma and, dead last, Louisiana.

The brain health evaluations, performed by researchers at Martek Biosciences Corp., were determined through an analysis of third-party data on the diet, physical health, mental health and social well being of the residents of each state.

I came across the ADDA website , www.add.org,and thought I would share it.  Many of us have or know kids or relatives with ADD.  Here is the latest newletter.

The kids are back in school and things are settling into a routine on the home front so it's time to catch up at work.  Everyone I talk to says they have too much to do and not enough hours in a day. Linda Walker's productivity tips in this month's article will come in especially handy.
 
ADDA is working hard to change public opinion and public policy concerning adults with ADHD. ADHD Awareness Day, which happened last Wednesday, September 16, is one such initiative. I hope you all had a happy ADHD Awareness Day!
 
Janet Kramer's story of Rose, a 23 year old mother who spent 18 months in prison for self-medicating her ADHD due to mandatory sentencing laws, touched many people.  Janet, an ADDA Board Member and Co-Chair of the ADDA Work Group on ADHD and Corrections, is leading the charge to prevent exactly this type of situation.
 
I'm proud to announce that along with other significant national organizations, ADDA became a signatory on a letter supporting S. 714, the National Criminal Justice Commission Act of 2009, which positively addresses issues very relevant to our members. Congratulations, Janet, the ADDA board and to you, our members. Without your support, we couldn't continue to do what we do for you.

ADDA works hard to bring you valuable services, so I'm sure you're aware of our Webinars program.  Well, there are more exciting Webinars coming up! For ADDA members only, next Wednesday, September 23, Marjorie Johnson will help us manage anger and conflict and the following Wednesday, September 30, Dr. Theresa Cerulli will explain medication management for ADHD.  On October 7, Ari Tuckman will hold a Q & A session that's open to everyone. If you've got questions, Ari's got answers!

This just in! Last Friday (September 18, 2009), Global TV in Canada aired an excellent documentary called "ADD and Loving It!" I watched it and thoroughly enjoyed it. It provided a balanced take on adult ADHD, and (politely) shot down all the usual arguments against it (bad parenting, food additives, etc.). I don't know if Global TV has any plans to air it again, or if it'll be available in the US, but it will be available for the next few days (until September 25, 2009 at http://news.globaltv.com/Loving/2009300/story.html. Enjoy!

A new study ranks the 'brain health' of all 50 states, with a heavy emphasis on a healthful omega-3 fat.   Zach Miners, U.S. News & World Report.  Omega-3 is very good for brain behavior and health.

If you sometimes find it difficult to concentrate or experience the occasional "senior moment," don't be too hard on yourself. It might just be the state you live in.

To raise awareness about the state of the nation's "brain health" and to encourage people to take action toward improving their own brain function, researchers released an index that purports to rank the "brain smarts" of all 50 states and the District of Columbia.

 The belief that healthy older brains are substantially smaller than younger brains may stem from studies that did not screen out people whose undetected, slowly developing brain disease was killing off cells in key areas, according to new research. As a result, previous findings may have overestimated atrophy and underestimated normal size for the older brain.
 

The seeming age-related atrophy in gray matter more likely reflected pathological changes in the brain that underlie significant cognitive decline than aging itself, the authors wrote. As long as people stay cognitively healthy, the researchers believe that the gray matter of areas supporting cognition might not shrink much at all.

Advance in neuroimaging are always exciting as they assist doctors and clinicians in treating patients with traumatic brain injury. 

Functional magnetic resonance imaging (fMRI) is a technique widely used in studying the human brain. However, it has long been unclear exactly how fMRI signals are generated at brain cell level. This information is crucially important to interpreting these imaging signals. Scientists from the Academy of Finland's Neuroscience Research Programme (NEURO) have discovered that astrocytes, support cells in brain tissue, play a key role in the generation of fMRI signals.

Functional magnetic imaging has become a highly popular method in basic neurobiological research, psychology, medicine as well as in areas of study that interface with the social sciences and economics, such as neuroeconomics. fMRI imaging does not directly measure the activity of nerve cells or neural networks, but local changes in cerebrovascular circulation during the execution of certain functions. Interpretation of the measurement data obtained with this method therefore requires a close knowledge of the cell-level mechanisms that are responsible for these local changes in cerebrovascular circulation.

A New Study from  the University of Tulsa, published in the Journal of Clinical and Experimental Neuropsychology (Neuropsychological impairment and psychosis in mania. Journal of Clinical and Experimental Neuropsychology, 2009;31(5):523-532),  finds Deficits involving executive function, working memory, speed of information processing, and new learning Occur in many people with mania. Factors that predict impairment remain poorly understood, but there are indications that psychotic features may correspond with increased risk of neurocognitive dysfunction during manic episodes.

"The current study examined neuropsychological function in 40 inpatients with bipolar I mania, 24 of whom presented with psychotic features. Compared to a control group, the inpatients showed worse executive function, speed of information processing, new learning, and dexterity. Nonetheless, presence of psychotic features failed to distinguish the inpatients with mania. Thus, psychotic features do not appear to increase neurobehavioral morbidity in people with mania, but presence of mania clearly corresponded with neurobehavioral dysfunction," wrote M.R. Basso and colleagues, University of Tulsa.

The incidence of Alzheimer's is known to affect adult brains in later years.  But did you know the incidence also increases after and as a result of traumatic brain injury?

Alzheimer's disease is the most common form of dementia. The disease gets worse as it develops - it is a progressive disease. There is no current cure for Alzheimer's, although there are ways of slowing down its advance and helping patients with some of the symptoms. Alzheimer's is also a terminal disease - it is incurable and causes death.

According the National Institute on Aging, there are estimated to be between 2.4 million and 4.5 million Americans who have Alzheimer's. There are approximately 417,000 people in the UK with Alzheimer's, according to the Alzheimer's Society.

Alzheimer's disease is a progressive neurologic disease of the brain leading to the irreversible loss of neurons and the loss of intellectual abilities, including memory and reasoning, which become severe enough to impede social or occupational functioning.

An excellent look at the history, causes and diagnosis of Alzheimer's can be found by clicking here.

My collegue and friend David Kracke writes from Oregon:

Tim;

Thanks for sharing this informative and important study. I have always suspected this relationship between TBI and symptoms consistant with Alzheimer's Disease. Having a study to confirm it helps significantly.

FYI: Check out an opinion piece I wrote that ran last month in the Oregonian: http://www.oregonlive.com/opinion/index.ssf/2009/06/maxs_law_one_tragedy_that_need.html

Thanks, Tim. Keep up the good work.

People in early stages of Alzheimer's disease have trouble focusing on what is important to remember, according to University of California-Los Angeles (UCLA) researchers.

"One of the first telltale signs of Alzheimer's disease may be not memory problems, but failure to control attention," said lead researcher Alan Castel, UCLA assistant professor of Psychology.

I had the opportunity to hold a brain during my trip to the morgue a few years ago. It was an amazing experience. The brain is soft and infirm. It looks relatively symmetrical with each half held together at the corpus callosum.  

But each half is not perfectly symmetrical and that goes against the pop psychological “left-right brain” theories. Actually each half is not a mirror image of the other which enables us to perform different tasks at the same time.

“In the 1990s psychologist Michael Corballis of the University of Auckland in New Zealand argued that the asymmetry of the brain – known as lateralization - was a key step in the evolution of our species, giving us language and additional mental powers that other animals lack.

“Today Corballis readily admits he was wrong. Lateralized brains are not unique to humans. Parrots prefer picking up things with their left foot. Toads tend to attack other toads from the right but go after prey from the left. Zebra fish are likely to look at new things with their right eye and familiar things with their left….”

The May 2009 edition of Discover Magazine published an article by Carl Zimmer who frequently publishes on brain issues. He says, “One hypothesis is that a lateralized brain is more powerful than one that works like a mirror image. Instead of two matching parts of the brain performing an identical task, one can take charge, leaving the other free to do something else.”

It seems that our ability to multitask is owed largely to our not so symmetrical brain halves. Zimmer’s article is fascinating and can be read by clicking here.

I found this article entitled  Building a Better Brain in The April issue of Discover Magazine and thought I would share this excerpt with my readers.

The Attention Edge
Pay attention to this paragraph and you are selectively concentrating on a task or idea while ignoring distractions like that dog barking down the street or your cell phone ringing. In a world of information overload and increasing multi-multitasking, you do not have to suffer from ADHD to have trouble focusing. You need no diagnosis to benefit from drugs that cut through the chaos and help you get things done.

Attention-focusing drugs, of course, have been here for years: Amphetamines, nicknamed “go pills,” were discovered in the late 19th century. By the 1940s these central nervous system stimulants were widely used to treat asthma and had become popular as “pep” and diet pills. They were embraced by members of the armed forces, especially pilots, who had to remain attentive to myriad tasks despite constant danger and fatigue. Rife with serious side effects, including hallucinations, anorexia, and heart problems, dextroamphetamine (trade name Dexedrine, better known as speed) is rarely used today by civilians. But the amphetamine mix Adderall and the amphetamine-related drug methylphenidate (Ritalin, Methylin, Concerta, among others) are commonly prescribed.

Exactly how these drugs work their magic remains unknown, but stimulants like Ritalin and modafinil influence the neurotransmitters dopamine and norepinephrine, which are essential for attention and memory skills. Both drugs inhibit reuptake, or reabsorption, of these neurotransmitters by neurons, thus prolonging their action. Modafinil also indirectly alters the action of glutamate, the main neurotransmitter used by neurons in the brain to send signals down the line. The center of action for all these drugs, says University of California at Davis psychiatrist Michael Minzenberg, is the prefrontal cortex, the part of the brain that is responsible for executive functions like sorting out conflicting thoughts, making choices, predicting events, and exerting social control.

William Burke of Neurologica wrote me about a project sponsored by Neurologica.  Here is a little of what they do:

According to a Cleveland Clinic study published in the March/April issue of the Journal of the American Healthcare Radiology Administrators, NeuroLogica’s CereTom® Portable Head/Neck multi-slice CT Scanner was found to have a dramatic economic and clinical benefit while imaging Intensive Care Unit (ICU) patients.

The study, conducted by Thomas Masaryk M.D., Department Chair of Diagnostic Radiology at Cleveland Clinic, and colleagues, concluded that portable head/neck CT scanning:

1.Provided significant savings in terms of cost and time while providing clinicians with diagnostic images equivalent to that of their fixed full body scanners

2.Allowed the fixed conventional scanner to be dedicated for a greater number of outpatient studies by eliminating the bottleneck of time-intensive ICU patients

3.Eliminated clinical dangers associated with the transport of critically ill patients

I will never forgot the experience of deposing the coroner in a brain injury case.  The deposition was at the morgue.  Afterward, we, the attorneys for all parties and the court reporter, were treated to a tour.  What amazed me most was how numbed the folks working there were to the noxious fumes that pushed their way into your olfactory center.

Then as a personal favor to me, I was permitted to hold brains that had been removed from bodies.  I was able to get a never before view of the brain's structure, texture and size. 

I recently came across an interesting article from someone having a similar experience. Discover Magazine contributor, Carl Zimmer, published "The Brain The Big Similarities & Quirky Differences Between Our Left and Right Brains," in the May 2009 issue.  Brain lateralization is the cooperation of right and left brain.  He states:

No matter how lateralized the brain can get, though, the two sides still work together. The pop psychology notion of a left brain and a right brain doesn’t capture their intimate working relationship. The left hemisphere specializes in picking out the sounds that form words and working out the syntax of the words, for example, but it does not have a monopoly on language processing. The right hemisphere is actually more sensitive to the emotional features of language, tuning in to the slow rhythms of speech that carry intonation and stress.

Neuroscientists know that the hemispheres work together and that they do so by communicating through the corpus callosum. But exactly how the hemispheres cooperate is not so clear. Perhaps paired regions take turns being dominant. That is known to happen in some animals. For instance, dolphins use this strategy to sleep and swim at the same time: One hemisphere remains active for hours, then fades while the other takes over. Bird brains switch as well. In order to sing, a songbird makes the two sides of its lungs open and close. The two hemispheres of the bird’s brain take turns controlling the song, each dominating for a hundredth of a second.

The intimate cooperation between the two hemispheres makes it all the more remarkable that a person can survive with just one—a sign that the brain is far more malleable than we once thought. After a hemisphere is forced to manage on its own, it can rewire itself to handle all the tasks of a full brain. In fact, two hemispheres can cause more trouble than one if they cannot talk clearly to each other. Neuro­scientists have linked some mental disorders, including dyslexia and Alzheimer’s, with a breakdown in left-right communication.

The two sides of the brain may be a legacy that we inherited from our wormlike ancestors. But their delicate balance of symmetry and specialization is now woven into the very essence of human nature.

The Diagnsotic and Statistical Manual IV (DSM IV) serves as the psychiatric source book for diagnosing disorders.    The manual is used in worker's compensation cases, personal injury cases, including brain injury, and in clinical and forensic psychiatric practice.

Now the Diagnsotic and Statistical Manual V (DSM V) is being created.  Shari Roan of the LA Times writes:

Psychiatrists are debating what is normal and what constitutes an illness. When that edition of the book often referred to as the “bible of psychiatry” is released in 18 months, most agree it will contain significant revisions based on information gathered from newer imaging techniques and genetic studies. Mental health advocates hope that the new edition will include information to help with diagnoses of those with mild versions of disorders, as well as those suffering from multiple disorders.

Leaders from the APA, the World Health Organization (WHO) and World Psychiatric Association (WPA) determined that additional information and research planning was needed related to specific diagnostic areas. The manual is being updated to deal with things obesity, gambling, sex addiction and Internet addiction -- formerly dismissed as harmful habits that could be defeated with willpower -- may also be labeled illnesses.

Biotech Week reported on May 23, 2009:

Remembering what's most important is central to daily life. For example, if you went to the grocery store but left your shopping list at home, you'd at least want to remember the milk and bread, if not the jam. Or, when packing for a trip, you'd want to remember your wallet and tickets more than your slippers or belt.

Even very early in Alzheimer's disease, people become less efficient at separating important from less important information, a new study has found (see also American Psychological Association).

 Knowing this, clinicians may be able to train people in the early stages of Alzheimer's to remember high-value information better, according to a report in the May issue of Neuropsychology, published by the American Psychological Association.

Neuropsychology is the area of neuroscience that studies relationships between brain function and behavior, with a central focus on human brain-behavior relationships. Neuropsychological research attempts to map the brain structures and functions that are critical for particular mental/cognitive, emotional, and behavioral capacities.

As my father approaches 70 and my grandmother 87, early onset of Alzheimers is a reality for me.  Making sure they get proper diagnosis and treatment is paramount should signs and symptoms appear.  We should all be mindful of those we love as they age.

Senator Kennedy suffers from a specific cancer of the brain.  It had been more than 10 years since a new treatment for glioblastoma was approved, but the U.S. Food and Drug Administration has now granted accelerated approval for the cancer drug Avastin for use against the aggressive brain cancer tumors, Business Week reports.

The FDA (Food and Drug Administration, USA) approved Avastin (bevacizumab) for patients with GBM (glioblastoma multiforme) whose cancer carries on progressing after standard therapy. GBM is a rapidly progressing cancer - it invades brain tissue and can may have a significant effect on a patient´s mental abilities and physical activities. Approximately 6,700 people each year in the USA are affected by GBM.

Unfortunately, the cancer nearly always comes back, even when treated with surgery, radiation and/or chemotherapy.

Richard Pazdur, M.D., director of the Office of Oncology Drug Products in the FDA's Center for Drug Evaluation and Research, said "This type of cancer is very resistant to therapy and thus challenging to treat. Avastin provides a therapy for patients with progressive GBM who have not responded to other medications."

The American Association of Neurological Surgeons reported research on Depression this month.

Electroconvulsive therapy (ECT) is effective in approximately 70 percent of cases in which antidepressant medications do not provide adequate relief of symptoms. However, as many as 20 to 50 percent of patients who initially respond well to ECT treatment, suffer a relapse within six months, therefore, periodic maintenance therapy is often required.

Researchers at three medical schools, Harvard, University of Pittsburg and Medical College of Wisconsin, counducted a study entitled "Long Term Follow-up of Cortical Stimulation to Treat Major Depressive Disorder."  They investigated ECT stimulation for patients with major depressive disorder.

The World Health Organization rates major depression as the top cause of disability worldwide, with an estimated 340 million people suffering from an episode of major depression every year. While most patients with major depression find relief through a combination of psychotherapy and medication, about 20 percent of patients fail to respond. Patients who are most resistant to medications, psychotherapies, and electroconvulsive therapy (ECT) have little hope of recovery, and suffer a heightened risk of suicide and mortality. Sadly, statistics show that the suicide rate in people with major depression is as high as 15 percent.

A new study reveals by Italian and American neuroscientists In Nature Neuroscience reveals that ,  a simple decision-making task does not involve the frontal lobes, where many of the higher aspects of human cognition, including self-awareness, are thought to originate. Instead, the regions that decide are the same brain regions that receive stimuli relevant to the decision and control the body's response to it.

And for anyone who read Malcolm Gladwell's "Blink," there is support for the assertions that decisions are deeply seeded resonses.

Although the idea that instrumental learning can occur subconsciously has been around for nearly a century, it had not been unequivocally demonstrated. Now, a new study published by Cell Press in the August 28 issue of the journal Neuron used sophisticated perceptual masking, computational modeling, and neuroimaging to show that instrumental learning can occur in the human brain without conscious processing of contextual cues.

The old adage that you should always trust your instincts is supported for the first time by a scientific study.

But there has been a more subtle phenomenon, billed as the foundation of intuition, where a seasoned poker player may play more successfully because they can pick up subtle signals in the body language of their opponents - without consciously realising it - to work out if they are bluffing..

Now, a new study published in the journal Neuron uses a blend of techniques, including brain scanning, to provide the first hard evidence that this so called "instrumental learning" can occur, showing we should trust our instincts.

In popular books such as Blink, it has been claimed that this form of intuition can result in a better decision than conscious reasoning, says lead author Dr Mathias Pessiglione from the Wellcome Trust Centre for Neuroimaging at the University College London.

An article in the LA Times reports a study concluding that Brain Stimulation Improves Severe Depression.

Major depressive disorder affects about 14 million people in the U.S., and 10% to 20% of them do not respond to standard medical treatment, according the study.

In the fast-paced atmosphere of the modern world, where everyone has somewhere to be or something that needs to be taken care of, it's very easy for our lives to fall out of focus. Whether we're taking care of the needs of others or pushing to maintain our stamina in a hectic workplace, we often put our own personal needs at the end of our to-do lists. It's very easy for the blues to hang on a little longer than it should.

The nine men and 11 women in the trial had not improved on multiple medications, psychotherapy and electroconvulsive therapy. Subjects had been taking an average of four medications when the trial began in 2003 and had suffered from major depression for an average of 6.9 years.

Deep brain stimulation is approved to treat essential tremors and Parkinson's disease. Electrodes, which are permanently implanted in the brain, are powered by batteries and can be turned on and off by an external controller.
 

A new study with expanded participants is underway.
