A recent study published in the journal Neurology has found that insomnia symptoms may significantly increase an individual's risk of stroke, particularly if they are under the age of 50. The study analyzed data collected from over 30,000 participants over an 18-year period, making it one of the only studies to examine this particular link. Participants were sorted into nine groups based on self-reported symptoms of insomnia, with each new symptom increasing stroke risk by 7%. Individuals with five to six symptoms of insomnia were up to 51% more likely to have a stroke during the study period.
The study's findings suggest that insomnia's link to stroke risk exists within a broader understanding of how it can also lead to other conditions such as diabetes, hypertension, and dyslipidemia. Moreover, the risk of stroke was sustained over a long period, indicating that the interconnected risk is unlikely to resolve itself on its own. As such, the authors suggest that increased awareness and management of insomnia symptoms may contribute to the prevention of stroke occurrence.
While the study's reliance on self-reported symptoms may lead to challenges, experts believe that the research adds to the significant body of work being contributed to the effects of lack of sleep. The study also highlights the need for individuals to communicate with their care team and to consider sleep as a more formal stroke risk factor. Experts stress the importance of seeking treatment for insomnia, which can potentially reduce the risk of stroke.
Overall, this study provides valuable insights into the link between insomnia symptoms and stroke risk, particularly for younger individuals. While further research is needed to confirm the study's findings, it serves as a reminder of the importance of prioritizing good sleep hygiene and seeking appropriate treatment for sleep disorders.
