Obsessive compulsive disorder linked to increased ischemic stroke risk later in life
Thursday, May 27, 2021
Adults who have obsessive-compulsive disorder (OCD) were more than three times as likely to have an ischemic stroke later in life compared to adults who do not have OCD, according to new research published today in Stroke, a journal of the American Stroke Association, a division of the American Heart Association.
“The results of our study should encourage people with OCD to maintain a healthy lifestyle, such as quitting or not smoking, getting regular physical activity and managing a healthy weight to avoid stroke-related risk factors,” said study senior author Ya-Mei Bai, M.D., Ph.D., a professor in the department of psychiatry at Taipei Veterans General Hospital and National Yang Ming Chiao Tung University College of Medicine, both in Taiwan.
Worldwide, stroke is the second-leading cause of death after heart disease. Stroke is a medical emergency that occurs when blood and oxygen flow to the brain are interrupted, usually by a blood clot (ischemic stroke). Less common is stroke from a burst blood vessel that causes bleeding in the brain (hemorrhagic stroke). In both types of stroke, immediate treatment is critical to prevent brain damage, disability or death. The abbreviation F.A.S.T. can help people remember the warning signs and what to do: F-face drooping, A-arm weakness, S-speech difficulty, T-time to call 9-1-1.
OCD is a common, sometimes debilitating, mental health condition characterized by intrusive, unwanted thoughts, ideas or sensations (obsessions) that make a person feel driven to do something repetitively (compulsions). The repetitive behaviors characteristic of OCD, such as hand washing, checking on things or continuously cleaning, can significantly interfere with a person’s daily activities and social interactions. Previous research found that OCD often occurs after stroke or other brain injury. What remained unclear was whether the reverse is true: can OCD increase stroke risk?
