"Chronic traumatic encephalopathy (CTE) occurs after a person receives repeated brain injuries, including concussions and subconcussive injuries. In a new study in Neurology, researchers at the Boston University Medical Center found that people affected by CTE first showed changes in one of two areas: mood and behavior or memory and thinking. CTE most commonly occurs in military personnel or in professional athletes. The researchers studied the brains of 36 athletes whose brains showed signs of CTE that were noted after death, and interviewed friends and family about their patterns of mood, behavior, and daily living habits. Two-thirds of the athletes had mood and behavior problems as their first CTE symptoms, while the other third first presented with memory problems. The first group had more out of control behavior, including explosive violence, than the second group, and also showed more symptoms at an earlier age. The study is limited, the researchers say, by a non-CTE control group. Read more: bit.ly/19xSpg7 Journal article: Clinical presentation of chronic traumatic encephalopathy. Neurology, 2013.
