A group of NFL players recently announced that they were suffering from negative effects of chronic traumatic encephalopathy. CTE is a brain condition caused by repeated head trauma, usually from concussions. CTE can result in memory loss, depression, aggression and dementia.
So far, it's been shown that 50 deceased football players suffered from CTE before they died. Until recently, CTE could only be diagnosed through an autopsy. However, researchers are now able to detect CTE through special brain scanning techniques while patients are still alive. This new technology is an amazing step forward to assist football players in preventing further injury and/or the worsening of their conditions.
