People who have suffered a traumatic brain injury have a significantly higher risk of dementia, including Alzheimer’s disease, than people who have no history of injury.
In one of the largest studies on the subject, published Tuesday in The Lancet Psychiatry, researchers studied 2.8 million patient records. They found people with a history of brain injury had a 24 percent higher risk of dementia than those who did not.
The Centers for Disease Control and Prevention defines traumatic brain injury as “a disruption in the normal function of the brain that can be caused by a bump, blow or jolt to the head, or penetrating head injury.”
Approximately 50 million people worldwide experience such injuries per year, a press release from the University of Washington School of Medicine reported. About 47 million people worldwide suffer from dementia.
