Changes in WMH volume did not correlate with changes in cognitive function over 48 months.CONCLUSIONS: Activated platelets and thrombogenic MV as surrogate markers of cardiovascular risk contribute to progression of WMH. Increases in WMH do not appear to impact cognitive performance in this healthy cohort of recently menopausal women.Supported by: Aurora Fund, HL90639, NS066147, HD65987, AG029624, Mayo Foundation.Disclosure: Dr. Raz has nothing to disclose.
