Head thrust: Increases the risk for depression?

US scientists have found evidence that repeated concussions of the head can affect memory and even depression could trigger. This was not the case, even if the shocks were strong enough to symptoms of a concussion to trigger.

In the journal "Neurology" the researchers report that participants of a survey, the earlier contact sport, experiences of violence or military service repeatedly exposed to head impacts, more likely to have depression. This connection may be dose-dependent, because the depressive symptoms were more pronounced in the people the most, who had also suffered concussions, and unconsciousness.

The intellectual Fäskills suffer

A similar effect was observed in Tests that the memory, Learning, processing speed and reaction time of subjects were studied: The best participants performed without blows to the head or concussions in the history, while the performance of participants with head injury were worse. Individuals with repeated head impacts, concussion and loss of consciousness achieved in almost all Tests, the worst results.

The neurologist Prof. Dr. Robert Stern reassured, however: "Not all people who suffered a history of blows to the head, later impairment of their mental abilities, or depression. Nevertheless, the results of this study suggest that repeated head-butting, playing regular Football, a role in the development of these later mental and emotional problems play."
