Brain Damage has been shown in cases of Mild Traumatic Brain Injury. Sounds like a little preaching to the choir.
A new article in the July 16, 2014, online issue of Neurology®, the medical journal of the American Academy of Neurology, discloses findings of brain injured versus non-brain injured individuals.
For the study, 44 people with a mild traumatic brain injury and nine people with a moderate traumatic brain injury were compared to 33 people with no brain injury. All of the participants took tests of their thinking and memory skills. At the same time, they had diffusion tensor imaging scans, a type of MRI scan that is more sensitive than traditional MRI for detecting damage to brain cells and helps map fiber tracts that connect brain regions. The people with brain injuries had their scans an average of six days after the injury. A year later, 23 of those with injuries had another scan and took the cognitive tests again.
Compared to the people with no brain injury, those with injuries had brain damage in brain white matter consisting of disruption to nerve axons, those parts of nerve cells that make up white matter and that allow brain cells to transmit messages to each other.
So goes the myth that "mild" traumatic brain injury has no lasting effects on its victim.
