Can You Have a Stroke in Your Sleep?
Sleep Disorders and Stroke Risk
Obstructive Sleep Apnea (OSA) and Stroke
Obstructive sleep apnea (OSA) is a significant risk factor for stroke. Severe OSA can double the risk of having a stroke, particularly in young to middle-aged individuals. Continuous positive airway pressure (CPAP) therapy has been shown to reduce stroke risk, especially in patients who adhere to the treatment. The prevalence of OSA is notably high among stroke patients, and it can be effectively assessed using polygraphy.
Sleep Duration and Stroke Risk
Both short and long sleep durations are associated with an increased risk of stroke. Long sleep, in particular, has been linked to a higher risk of stroke, with a hazard ratio (HR) of 1.46 after adjusting for various covariates. Short sleep duration also presents a risk, although the association is less pronounced. Persistently long sleep or a significant increase in sleep duration over time further elevates stroke risk.
Other Sleep Disorders and Stroke
Sleep disorders such as insomnia, restless legs syndrome (RLS), and periodic limb movements during sleep (PLMS) are also associated with stroke. Insomnia and RLS are common in stroke patients and are linked to poorer stroke outcomes. PLMS, but not RLS, may increase the risk of stroke. Additionally, sleep disturbances like difficulty falling asleep, maintaining sleep, and poor sleep quality are significantly associated with an increased risk of acute stroke.
Stroke Occurrence During Sleep
Sleep-Related Breathing Disorders
More than 50% of stroke patients experience sleep-disordered breathing (SDB), primarily in the form of OSA. SDB is both a risk factor for and a consequence of stroke, and its presence is linked to poorer long-term outcomes and increased stroke mortality.
Sleep Architecture and Stroke
Stroke survivors often exhibit altered sleep physiology compared to healthy individuals. They tend to have lower sleep efficiency, shorter total sleep time, and more wake time after sleep onset. These changes in sleep architecture can negatively impact recovery and overall health.
Bidirectional Relationship Between Sleep and Stroke
There is a bidirectional relationship between sleep disorders and stroke. Sleep disturbances can increase the risk of stroke, and stroke can lead to various sleep disorders . This complex interaction underscores the importance of addressing sleep issues in stroke prevention and recovery.
Conclusion
Yes, it is possible to have a stroke in your sleep. Sleep disorders, particularly OSA, significantly increase the risk of stroke. Both short and long sleep durations are associated with higher stroke risk, and various sleep disturbances can contribute to this risk. Addressing sleep disorders through appropriate interventions like CPAP therapy for OSA can potentially reduce stroke risk and improve outcomes for stroke patients. Further research is needed to fully understand the mechanisms and develop effective prevention and treatment strategies.
