Concussion does not have to result in loss of consciousness for it to be followed by a higher risk of developing dementia. This was the conclusion of a large study of veterans in the United States that found that the risk of developing dementia more than doubled following mild traumatic brain injury (TBI) without loss of consciousness.
Other studies have shown that moderate and severe TBI are followed by a higher likelihood of developing dementia, but evidence of a link with mild TBI — particularly where no loss of consciousness occurs — was somewhat patchy.
