Sleep and Stroke-An Overlooked Bidirectional Influence: Why Should Sleep and Vascular Neurologists Work Closer?

Area of Science:

• Neurology
• Sleep Medicine
• Cardiovascular Research

Background:

• The link between sleep-wake disorders and cerebrovascular events is increasingly recognized.
• International guidelines now identify sleep disorders as risk factors for ischemic stroke and poor outcomes.
• Despite established associations, therapeutic evidence for sleep interventions in stroke prevention is limited.

Purpose of the Study:

• To review advances in the bidirectional relationship between sleep disorders and stroke.
• To discuss pathophysiological mechanisms, particularly autonomic nervous system activation.
• To critically appraise current research and future directions.

Main Methods:

• Literature review of recent advances in sleep disorders and stroke.
• Discussion of proposed pathophysiological mechanisms.
• Critical appraisal of existing research and future perspectives.

Main Results:

• Sleep disorders are formally recognized as risk factors for ischemic stroke.
• Sleep disorders significantly influence short- and long-term stroke outcomes.
• Limited therapeutic evidence exists for sleep interventions in stroke prevention.

Conclusions:

• A strong association exists between sleep disorders and stroke risk and outcomes.
• Further well-designed clinical trials are needed to validate sleep interventions for stroke prevention.
• Enhanced collaboration between sleep and stroke specialists is crucial for patient care.
