No injury is good, especially when it’s a traumatic brain injury. The most common and least serious type of traumatic brain injury, a concussion is still nothing to neglect. If suffered enough and depending on the severity, concussions can sometimes cause long-term and/or even permanent damage.
In fact, last September, it was announced that nearly every studied brain of former NFL players tested positive for chronic traumatic encephalopathy, or CTE — a degenerative disease found in people with repetitive trauma to the brain.
For years, the NFL attempted to ignore evidence, but the league finally stated in federal court documents last year that it expects nearly a third of its players to develop long-term cognitive issues.
