Brain injuries increase the risk of long-term stroke

WEDNESDAY, April 21, 2021 (HealthDay News): People suffering a trauma brain injuries (TBI) have a significantly higher risk of suffering stroke for years afterwards, say UK researchers.

Previous studies have linked brain injury to a long-term risk of neurological diseases, including dementia, Parkinson i epilepsy, and has been suggested to be an independent risk factor for stroke.

This new review of 18 studies from four countries found that patients with these lesions have an 86% higher risk of stroke than people who have not had TBI.

Although the added risk of patients may be higher in the first four months after their risk head wound, remains significant for up to five years, according to the authors of the new review.

“Patients with TBI should be informed about the potential for increased risk of stroke and, with a maximum risk of stroke in the first four months after injury, is a critical period to educate patients and their caregivers about stroke risk and symptoms, ”said lead author Grace Turner, a member of the University of Birmingham’s Institute for Applied Research.


She and her colleagues found that TBI is a risk factor for stroke regardless of the severity or type of injury.

They said this is significant because 70% to 90% of these blows to the head are mild. The finding suggests that TBIs should be considered a chronic disease even when they are mild and patients recover well, they added.

The use of certain anticoagulants, as vitamin K antagonists (VKAs) i statins, could help reduce the risk of stroke in patients with TBI, while some classes of antidepressants are associated with an increased risk of stroke after injury, according to the results. The study was recently published in International stroke magazine.

“Our review has found some evidence to suggest an association between reduced risk of post-TBI stroke and stroke prevention drugs VKAs and statins, but, as previous studies have found, drug prevention drugs ‘Strokes often stop when an individual experiences a TBI,’ Turner said in a college press release.

More research is needed to evaluate the effectiveness of medications in preventing stroke after a brain injury to help guide treatment.


Turner said doctors should use the initial four-month period after a TBI to take steps to reduce patients’ excess risk of stroke.

More than 60 million people worldwide suffer a traumatic brain injury each year, while stroke is the second leading cause of death and the third leading cause of disability worldwide, according to the research team.
