MMA fighters have the potential risk of getting brain damage during a bout due to the potential of jarring impacts to the head and neck. The short-term effects of a head injury can include headache, confusion, and balance issues. The long-term effect can include chronic traumatic encephalopathy (CTE), which can lead to severe cognitive and behavioral changes, including memory problems, confusion, impaired judgment, aggression, depression, and impulsivity. Therefore, it is important for MMA fighters to take the necessary precautions to avoid any long-term damages to their brain.
