Concussion causes Alzheimer

Concussion can cause dementia, as established researchers. It detected most clearly in the relationship today between moderate head injuries and incurable brain disease.

concussion significantly increases the risk of developing dementia as the researchers found. Conducted among the wounded war veterans brain scans showed a clear link between head injuries and a decrease in the protective mechanisms of brain regions that are vulnerable to the incurable disease. Until recently, doctors believed severe brain injury a key risk factor for neurodegenerative diseases such as senile dementia. But this is the first study that demonstrated that even mild injuries like concussions can cause grave consequences.

This discovery came in the wake of other studies in which the authors studied the number of concussions among students, practicing football, rugby and the like contact game. The authors of this study from Boston University studied the brains of 160 veterans who participated in the military operations of the US military in Iraq and Afghanistan. Some of them are faced with one or more of a concussion, and others never gave similar injuries.

Using magnetic resonance imaging, the researchers were able to estimate the thickness of the cerebral cortex in 7 of its areas that are beginning to show the first atrophy in the progression of Alzheimer's disease, as well as more control in 7 areas. It has been proven that concussions are associated with a reduced thickness in cortical areas of the brain that are affected in Alzheimer's disease. Coupled with genetic factors concussion can cause rapid decline and memory impairment in areas of the brain associated with Alzheimer's disease. What is most sad is these brain abnormalities have been found even in relatively young people with an average age of 32 years.
