Brain Injuries Increase Risk of Stroke

People who have had a traumatic brain injury face a tenfold increase in the risk of having a stroke within three months, according to a new study.

Traumatic brain injury occurs when a blow or jolt to the head causes changes in a person’s normal brain function. It can result from injuries such as falls, vehicle accidents, and violence.

Although previous research has shown that traumatic brain injury can be associated with the future development of epilepsy, Alzheimer’s disease, and psychiatric conditions, this the first study to link it to the future risk of stroke.

 The study appears in the July 28 online issue of Stroke: Journal of the American Heart Association.
