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.
