Adherence
A higher cumulative burden of sleep disturbance symptoms (Sleep Disturbance Symptom Burden >5) is associated with a graded, significantly increased risk of acute stroke, with the highest burden showing an OR of 5.38.
If you experience multiple sleep problems (e.g., short/long sleep, poor quality, snoring, napping), your stroke risk increases significantly. The more symptoms you have, the higher the risk. Seek a comprehensive sleep evaluation to address all symptoms, not just one.
GoodSupportsHIGH confidence
In the analysis of Sleep Disturbance Symptom Burden, an increasing number of symptoms were associated with a graded increase in stroke risk (2–3: OR 1.63, 95% CI 1.36–1.96; 4–5: OR 3.08, 95% CI 2.49–3.80; and >5: OR 5.38, 95% CI 4.03–7.18)... with the latter showing a graded association.
Why this rating
Large international study, clear dose-response relationship, robust adjustment.

More from this paper
- Short sleep duration (<5 hours) and long sleep duration (>9 hours) are independently associated with a significantly increased risk of acute stroke, exhibiting a U-shaped relationship where short sleep shows a higher magnitude of association on univariate analysis but attenuates more than long sleep after adjusting for comorbidities.Good
- Symptoms of Obstructive Sleep Apnea (snoring, snorting, breathing cessation) and a derived OSA score of 2-3 are significantly associated with increased odds of acute stroke, independent of a formal OSA diagnosis.Good
