How do previous concussions affect new concussion symptoms?

Christopher Giza, MD
Pediatrics
With a second concussion, sometimes the symptoms are worse. Second concussions need to be prevented because of biological vulnerability.  The more concussions people have had in the past, the longer it takes them to get better. If you can avoid that second concussion you can reduce the amount of school that gets missed and you can reduce the amount of sports that gets missed.

Multiple concussions do not necessarily lead to a long-term dementia problem, but after a second concussion it will take longer to get better. A study showed that the people who get better quickly are those who have had no concussions in the past, while those who take longer to recover have had one, two or three concussions.
