Dr. Ann McKee says that even though CTE is triggered by trauma, at some point it becomes trauma-independent. Studies show that chronic traumatic encephalopathy (CTE) is a progressive disease. While it takes time for the disease to become full-blown, there are many examples of suicidality, impulsivity, depression, erratic behaviors, and lack of self-control in young athletes with low-level CTE.
