Even mild concussion can raise long-term risk of dementia: Study
Minor brain injuries at a young age that lead to concussion even for a short period may impact the brain later, and raise the risk of dementia, finds a study.
The study, led by researchers at the University of Cambridge in the UK, aimed to learn more about the impact of concussions -- classified as traumatic brain injuries (TBIs) -- or other minor brain injuries on dementia.
