To investigate the association between insomnia symptoms and the risk of ischemic stroke and overall stroke risk.
Key Findings:
Diagnosed insomnia was linked to a 45% greater likelihood of ischemic stroke, distinct from general insomnia symptoms.
Interpretation:
The findings suggest that while insomnia symptoms may not increase the risk of overall stroke types, they are associated with a higher risk of ischemic stroke, particularly when diagnosed clinically.
Limitations:
Limited generalizability due to most studies being conducted in high- and middle-income countries, with no studies from low-income settings.
Conclusion:
Future research should utilize objective sleep measures and include more diverse populations to better understand the relationship between insomnia and stroke risk.
