Obstructive sleep apnoea syndrome (OSAS) is an independent stroke risk factor, frequently occurring in acute stroke patients. Screening for OSAS in stroke patients is recommended due to its association with poor outcomes.

Area of Science:

  • Neurology
  • Sleep Medicine
  • Cardiovascular Science

Background:

  • Obstructive sleep apnoea syndrome (OSAS) is increasingly recognized as an independent risk factor for stroke.
  • While OSAS is often a cause of stroke, it can also be a consequence, particularly with brainstem lesions.
  • A high prevalence of OSAS (70-95%) is observed in acute stroke patients.

Purpose of the Study:

  • To review the evidence linking OSAS and stroke.
  • To discuss the prevalence, risk factors, and consequences of OSAS in stroke patients.
  • To highlight the importance of OSAS screening in acute stroke.

Main Methods:

  • Systematic review of recent studies on OSAS and stroke.
  • Analysis of identified risk factors and predictors for stroke.

Related Experiment Videos

  • Discussion of potential pathophysiological mechanisms connecting OSAS and stroke.

    • Main Results:

    • OSAS is an independent risk factor for stroke.
    • Independent predictors of stroke include age, BMI, diabetes, and stroke severity.
    • OSAS presence in stroke patients is linked to poorer outcomes.
    • Potential linking mechanisms include hypertension, arrhythmias, atherogenesis, coagulation, and cerebral haemodynamics.

    Conclusions:

    • Systematic screening for OSAS is recommended in clinically suspected acute stroke patients.
    • The optimal timing for initiating nasal continuous positive airway pressure treatment requires further determination.
