Dr Connor diagnoses "Pitbull" with Chronic Traumatic Encephalopathy (CTE) from a CT brain scan. However, CTE cannot be diagnosed in living individuals. The first confirmed diagnosis of CTE in a living patient was confirmed by an autopsy after the patient's 2017 death; a tentative diagnosis of CTE had been made about two years prior. Those with CTE-related symptoms may receive medication and non-medication related treatments.
