There is new research that indicates baseball great Lou Gehrig may not have died from ALS, or so-called Lou Gehrig's disease.
Dr. Mike explained on "Good Day," doctors are learning a lot more about the long-term effects of concussions. A new study examined the brains of professional athletes, who had sustained numerous concussions, and they found all had a condition called chronic traumatic encephalopathy. The condition causes cognitive decline, abnormal behavior and dementia. The symptoms are very similar to Lou Gehrig's disease. Some researchers believe this condition may be what actually killed Gehrig.
Dr. Mike said it's important for parents to get proper medical care if they think their child has sustained a concussion. Dr. Mike explained the brain is actually "jostled" when there is a concussion. "The skull is hard, it's a contained area, and the brain has no where to go. What happens is it causes damage to the little neurons and leads to a condition where you have protein buildup."
Gehrig died in 1941 at the age of 37.
