Objective:

To investigate the association between insomnia symptoms and the risk of ischemic stroke and overall stroke risk.

Approach:
    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.
