Summary
Obstructive Sleep Apnea Syndrome (OSAS) is linked to increased stroke risk. OSAS patients exhibit altered cerebral blood flow even when awake, potentially explaining their higher risk of ischemic strokes.
Area of Science:
- Neurology
- Cardiology
- Sleep Medicine
Context:
- Obstructive Sleep Apnea Syndrome (OSAS) is a known risk factor for cardiovascular diseases, particularly stroke.
- The underlying mechanisms connecting OSAS to stroke remain incompletely understood.
Purpose:
- To review existing theories on the OSAS-stroke association.
- To investigate potential alterations in cerebral hemodynamics in OSAS patients.
- To explore the link between cerebral blood flow and stroke risk in OSAS.
Summary:
- This work reviews theories linking OSAS to stroke and examines cerebral hemodynamic alterations.
- A case-control study revealed significant differences in cerebral blood flow between OSAS patients and healthy individuals during wakefulness.
- These hemodynamic changes may elucidate the elevated risk of ischemic strokes in OSAS patients.
Impact:
- Provides potential mechanistic insights into the increased stroke risk associated with OSAS.
- Highlights the importance of cerebral blood flow abnormalities in OSAS.
- Suggests that addressing hemodynamic alterations could be crucial in managing stroke risk in OSAS patients.
