Does aspirin affect outcome in vascular dementia? A retrospective case-notes analysis

Area of Science:

• Neurology
• Gerontology
• Pharmacology

Background:

• Ischaemic vascular dementia shares risk factors with stroke.
• Controlling vascular risk factors may prevent or modify vascular dementia.
• Aspirin is a common medication for stroke prevention.

Purpose of the Study:

• To assess the effect of regular low-dose aspirin on outcomes for patients diagnosed with vascular dementia.

Main Methods:

• Retrospective analysis of hospital case-notes and general practitioner records.
• Compared outcomes for 78 patients with ischaemic vascular dementia (38 on aspirin).
• Survival to institutionalization and death were the primary outcome measures.

Main Results:

• No overall difference in survival between aspirin and non-aspirin groups.
• Aspirin showed a trend towards longer institutionalization time and significantly longer survival time in patients living with a carer.
• These effects were not statistically significant after adjusting for confounding variables.

Conclusions:

• Results suggest a potential role for low-dose aspirin in improving life expectancy and home survival for vascular dementia patients.
• Compliance with aspirin may be higher in patients with carer support.
• Larger, prospective studies are recommended to confirm these findings and explore cognitive outcomes.
