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
