Summary
Delirium affects over 10% of acute stroke patients, often appearing early and during night shifts. Early detection and prevention are crucial as delirium is linked to increased complications and disability in stroke survivors.
Area of Science:
- Neurology
- Geriatrics
- Psychiatry
Background:
- Delirium is a common complication in acute stroke patients.
- Early identification of risk factors and outcomes is essential for effective management.
Purpose of the Study:
- To determine the prevalence of delirium in acute stroke patients.
- To identify risk factors associated with delirium in this population.
- To analyze the clinical outcomes of stroke patients with delirium.
Main Methods:
- Prospective observational study of 309 adult stroke patients on a primary stroke unit.
- Delirium assessed using the Confusion Assessment Method (CAM) multiple times daily.
- Confounder-matched case-control analysis for significant risk factors.
Main Results:
- Delirium prevalence was 10.7%, frequently occurring on the first/second day and sometimes exclusively at night.
- Key risk factors included dementia, age ≥72, severe neurological disability, and elevated C-reactive protein.
- Delirious patients experienced more complications and a trend towards poorer rehabilitation.
Conclusions:
- Highlights the need for vigilant delirium screening in stroke patients, particularly overnight.
- Emphasizes that even brief delirium episodes correlate with adverse outcomes.
- Suggests further research into delirium prevention strategies for stroke patients.
