The suicide of Ohio State University athlete Kosta Karageorge, who allegedly suffered from debilitating concussions, has raised more questions about the scientific connections between brain trauma and lasting psychological damage. Traumatic brain injury, including injuries like concussions, often affects soldiers exposed to explosives and athletes like football players and boxers. Such injuries can have symptoms like confusion and amnesia, and may also lead to long-term health issues like chronic traumatic encephalopathy, a degenerative disease.
