Currently, chronic traumatic encephalopathy (CTE) can only be definitively diagnosed after death through a brain autopsy. However, if you are concerned you might have CTE, especially if you have a history of repeated head injuries or concussions, it’s important to recognize common symptoms and seek medical evaluation. Early signs of CTE may include memory loss, confusion, difficulty thinking (cognitive impairment), mood changes like depression or anxiety, impulsive behavior, and problems with balance or motor skills.
