Head injuries may play a role in the development of Alzheimer’s-type brain lesions
Previous research has suggested that traumatic brain injury (TBI) may be a major risk factor for dementia. A newly published study suggests that TBI may lead to a buildup of Alzheimer’s disease-type lesions in the brain, including in regions not typically affected by such damage. In this small, preliminary study, researchers found that moderate to severe head injuries led to an accumulation of amyloid plaques in nine middle-aged study participants over months or years.
