The degenerative brain disease known as chronic traumatic encephalopathy (CTE) has been a hot topic in the sports world, especially in light of the NFL recently admitting to the link between football and the disease. The topic even spawned the critically claimed movie, Concussion, starring Will Smith.
Although plenty of studies have pointed to the link between CTE and contact sports such as football, hockey and boxing, there are studies that have been published that suggest otherwise.
