Severe cerebral white matter hyperintensities predict severe cognitive decline in patients with cerebrovascular
Background And Purpose:
Cerebral white matter hyperintensities (WMHs) are believed to be the consequence of small vessel disease, and it is uncertain whether their extent predicts the risk of dementia in patients with vascular disease history. Method- Brain MRI was performed in 226 participants of the PROGRESS study. WMH severity was assessed using a visual rating scale. During follow-up, patients were classified for incident severe cognitive deterioration (including dementia) using standard criteria.
Results:
Over 4-year follow-up, the incidence of severe cognitive deterioration ranged from 1.1 to 9.1 per 100 person-years in patients with respectively no or severe WMHs at baseline. In multivariable analysis, incident severe cognitive deterioration was associated with baseline severe WMHs (odds ratio=7.7, P<0.005).
Conclusions:
Higher WMH load is a strong predictor of dementia and cognitive decline in patients with cerebrovascular disease history.
Insights
Extensive white matter hyperintensities (WMHs) significantly increase dementia risk in individuals with cerebrovascular disease. This finding highlights WMH load as a crucial predictor of cognitive decline.
Area of Science:
- Neurology
- Neuroimaging
- Gerontology
Background:
- Cerebral white matter hyperintensities (WMHs) are markers of small vessel disease.
- The predictive value of WMH extent for dementia in patients with vascular disease history remains unclear.
Discussion:
- Brain MRI assessed WMH severity in 226 PROGRESS study participants.
- Follow-up classified patients for incident severe cognitive deterioration, including dementia.
Key Insights:
- Over 4 years, severe cognitive deterioration incidence varied from 1.1 to 9.1 per 100 person-years based on baseline WMH severity.
- Severe baseline WMHs strongly predicted incident severe cognitive deterioration (OR=7.7, P<0.005) in multivariable analysis.
Outlook:
- Higher WMH load is a significant predictor of dementia and cognitive decline.
- This research underscores the importance of assessing WMH in cerebrovascular disease management.
