Concussion Sequelae Boost Alzheimer’s Risk

Concussion Sequelae Boost Alzheimer's Risk

Post-traumatic amnesia (PTA) and chronic vascular lesions caused by traumatic brain injury (TBI) is tied to an increased risk of subsequent Alzheimer’s disease (AD), new research suggests.

Results from a case-controlled retrospective study showed the presence of PTA or of vascular lesions on neuroimaging in patients with TBI was significantly associated with up to an almost fourfold increased risk of AD.
