Decoding CTE

The suspect in last week's mass shooting in midtown claimed to have a condition known as CTE, a traumatic brain injury from repeated hits of the head. CTE has notable been found in the brains of football players like Junior Seau and Aaron Hernandez. The problem with self-diagnosis is CTE can only be diagnosed during an autopsy. Today we speak with associate professor of neurology at Boston University, Dr. Jesse Mez , who studies CTE and its effects on the brain and the goal to find ways to diagnosis and treat.
