Summary
Stroke occurrence follows a circadian pattern with highest incidence in morning hours, linked to endogenous factors like blood pressure dipping and prothrombotic states that are regulated by the internal clock. Disruption of circadian rhythms may increase stroke risk and impair neurorehabilitation, suggesting that chronotherapy and lighting-based circadian support could be relevant interventions in stroke prevention and recovery.
Key Findings
- Stroke incidence follows a circadian pattern with peak occurrence in the morning hours, consistent across all subtypes including cerebral infarction and intracerebral hemorrhage.
- Circadian disruption is associated with increased neuronal susceptibility to ischemic injury and may negatively influence functional outcomes after stroke.
- Morning prothrombotic and hypofibrinolytic states, driven by circadian variation in the autonomic nervous system and humoral activity, contribute to elevated morning stroke risk.
- Chronotherapy and chronoprophylaxis targeting circadian-regulated risk factors (e.g., blood pressure dipping patterns) are identified as potentially beneficial strategies for stroke management.
