Chronic Traumatic Encephalopathy (CTE) is a progressive brain condition linked to repeated head injuries, commonly seen in athletes involved in contact sports. The disease is characterized by the buildup of tau protein in the brain, leading to symptoms such as memory loss, mood swings, and cognitive decline. CTE can only be definitively diagnosed post-mortem through brain tissue analysis, but awareness of its signs and risks is growing among athletes, coaches, and medical professionals. The article emphasizes the importance of concussion prevention, proper diagnosis, and ongoing research to better understand CTE. It highlights cases of former athletes who suffered from the disease and discusses efforts to improve safety protocols in sports. While there is no cure for CTE, increased education and protective measures aim to reduce its prevalence and impact on athletes' lives.
