University of Missouri research indicates there may be new hope in dealing with Post traumatic stress disorder commonly referred to as PTSD.

The brain is a complex system made of billions of neurons and thousands of connections that relate to every human feeling, including one of the strongest emotions, fear. Most neurological fear studies have been rooted in fear-conditioning experiments. Now, University of Missouri researchers have started using computational models of the brain, making it easier to study the brain's connections. Guoshi Li, an electrical and computer engineering doctoral student, has discovered new evidence on how the brain reacts to fear, including important findings that could help victims of post-traumatic stress disorder (PTSD).

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.

Many victims of traumatic brain injury develop Post Traumatic Stress Disorder.  I recently came across a great article on the symtoms, causes and other information of PTSD.

PTSD (Post-Traumatic Stress Disorder) is triggered by a traumatic event - it is a kind of anxiety. The sufferer of PTSD may have experienced or seen an event that caused extreme fear, shock and/or a feeling of helplessness. Most of us experience a brief period of difficulty adjusting and coping with traumatic events. However, we gradually get better with time and healthy coping methods. On the other hand, there are times when symptoms get worse and may last for several months, or years. This study explains how PTSD can surface two years after a traumatic event. Another study found that one in eight Lower Manhattan residents likely had PTSD two to three years after the 9/11 attacks.
