People with a history of hospital treatment for mental health conditions may be more likely to have a stroke, according to research published at the American Stroke Association’s annual International Stroke Conference.
Stroke is the fifth-leading cause of death in the United States. It is a leading cause of disability, and according to the American Stroke Association, 80% of strokes are preventable.
Is There a Link Between Mental Health and Strokes?
Researchers analyzed more than 52,000 strokes from the California Healthcare Cost and Utilization Project database. The strokes occurred from 2007-2009, and data were evenly split between women and men.
About 6% of participants in the study—3,337 people—had been treated at a hospital for a mental health condition such as posttraumatic stress (PTSD) or depression in the year prior to the stroke. Using a crossover analysis, the study looked at the link between mental health diagnoses and stroke risk.
Researchers found people hospitalized or treated in an emergency room for a mental health condition were 3.48 times more likely than their peers to have a stroke within 15 days of the hospitalization. They were 3.11 times as likely to have a stroke within 30 days.
Stroke Warning Signs
Researchers did not seek a causal connection between strokes and hospital treatment for mental health issues, so it remains unclear whether mental health conditions cause strokes or are linked to some other factor that elevates stroke risk.
The study’s authors speculate that mental health conditions might raise blood pressure via the fight or flight response, potentially increasing stroke risk. Mental health diagnoses are often linked to inflammation, which can raise the risk of strokes. It is also possible that poor mental health can undermine self-care by reducing the likelihood that a person takes prescribed medication to reduce the risk of stroke.
The American Stroke Association uses the acronym FAST to help people remember common symptoms of a stroke:
- F – Face drooping
- A – Arm weakness
- S – Speech difficulty
- T – Time to call 911
