The study found that concussions increase the risk of dementia

a new U.S. study found that concussions and more severe traumatic brain injuries increase the risk of dementia.
concussions are mild traumatic brain injuries. The study, conducted by a team at the University of California, San Francisco, targeting U.S. veterans, found that concussion patients had an increased risk of developing dementia, whether they lost consciousness or not.
, the risk of dementia increased to 2. 36 times; the risk of dementia in unconscious concussion patients increased to 2. 51 times; if moderate to severe traumatic brain injury is achieved, the risk of dementia increases to 3. 77 times.
team extracted data from nearly 360,000 patients from two U.S. databases: one for all veterans who suffered traumatic brain injuries while in or out of the military, and the other for veterans who suffered traumatic brain injuries as a result of bomb shock waves during the iraq or Afghanistan wars. The average age of the patients was 49.
related research papers were published in the
7th. Professor Deborah Barnes, lead author of the paper, said the results from the two databases were similar, suggesting that common concussions, like those caused by war, were associated with a risk of developing dementia.
senior author Professor Christine Yaff said brain damage accelerates neurodegenerative lesions, possibly because it causes abnormal protein build-up, leading to neuron death, or because trauma makes the brain more vulnerable to other injuries or aging. (Source: Xinhua Zhouzhou)
