    Study Notes

    Sleep Disorders and Stroke: Risk Factors, Frequency, and Treatment

    • Untreated severe obstructive sleep apnea (OSA) doubles the risk of incident stroke, especially in young to middle-aged patients, with no difference between men and women.
    • Evidence on OSA-associated risk for stroke in patients with coronary artery disease or atrial fibrillation is still insufficient, but available data suggest an increased risk in these populations, except for elderly patients.
    • CPAP treatment is associated with a reduced risk of stroke in patients with OSA, but results are variable. Patients adherent to CPAP therapy (>4 h per day) may benefit.
    • Insomnia slightly increases the risk for cardiovascular events, but the risk for stroke is uncertain. Prospective studies evaluating the association of insomnia with stroke risk are scarce, and all available studies are based on subjective measures to define insomnia, reducing the accuracy of exposure identification.
    • Chronic use of benzodiazepines and related drugs (BDZRs) for insomnia has been linked to increased risk of impaired cognitive function, dementia, and mortality.
    • Current evidence does not suggest an increased risk of stroke in patients with restless leg syndrome (RLS). Still, periodic limb movements in sleep may represent an independent risk factor for stroke.
    • The prevalence of SDB is high in stroke patients, with about 30% presenting with severe SDB (AHI > 30). Portable cardiorespiratory polygraphy is sufficient to assess the presence/severity of SDB in stroke patients in clinical practice.
    • Obstructive sleep apnea syndrome is a risk factor for recurrence of stroke or TIA and may increase all-cause mortality and worsen the neurological outcome in stroke patients.
    • CPAP treatment is feasible in stroke survivors with OSA and may improve neurological recovery, sleepiness, and depressive symptoms. Treatment of post-stroke OSA with CPAP should be included in an integrated management of multiple risk factors such as anticoagulation for atrial fibrillation, control of hypertension and dyslipidemia, exercise, and weight reduction.
    • The prevalence of insomnia in stroke patients is increased (at least 30%), with a link between post-stroke insomnia, female gender, and depression.
    • Restless limb syndrome in stroke patients is associated with subcortical/brainstem stroke and may be associated with a less favorable outcome. Data on the prevalence and impact of periodic limb movements in sleep after stroke are controversial.
    • No data are available on the impact of treatment of restless leg syndrome and periodic limb movements in sleep on mortality and outcome after stroke.
