DEAR MAYO CLINIC: What happens to the brain when someone suffers a concussion? Do concussions increase the risk of dementia or Alzheimer’s disease?
ANSWER: A concussion is a brain injury that changes the way your brain functions. The effects of most concussions are not long-lasting. But to avoid permanent damage, it is important to give someone who’s had a concussion plenty of time to rest and recover following the injury. Research does show that repeated concussions in some people can lead to cognitive impairment that could progress to Alzheimer’s disease or other types of dementia, such as chronic traumatic encephalopathy.
