Dr. Jeffrey Mjaanes, sports medicine physician at Midwest Orthopaedics at Rush and director of the Chicago Sports Concussion Clinic at Rush, appeared recently on WLS-TV to discuss the long-term effects of chronic traumatic encephalopathy (CTE). CTE is a progressive degenerative disease found in individuals who have been subjected to multiple concussions or other forms of head injuries. "The classic manifestations [of CTE] are not at the time of concussion," said Dr. Mjaanes. "These actually happen decades later. They're usually early onset dementia, depression or mood disorders, and then even suicide, or what we call parasuicide, or suicide attempts or ideation."
