New study shows Concussions may be linked to Alzheimer's disease

People who suffer concussions may be at a higher risk of developing plaques on the brain found in people with Alzheimer's disease, according to a study found in the journal Neurology

According to the Health page on the Fox News website, the new research released today examines the relationship between concussions and amyloid beta plaques in the brain. While this study doesn't exactly prove that concussions cause Alzheimer's disease, it does shed light on the long-term effects of traumatic brain injuries.

The study author, Michelle Mielke, scanned the brains of 589 people ages 70 and older. The brain scans revealed that those with memory problems and a history of head trauma had an average of 18 percent more amyloid beta plaques than those with no history of head trauma.

"Interestingly, in people with a history of concussion, a difference in the amount of brain plaques was found only in those with memory and thinking problems, not in those who were cognitively normal," Mielke said in a statement. "Our results add merit to the idea that concussion and Alzheimer's disease brain pathology may be related."
