These data support the sensitivity of a telephone-based test battery in measuring cognitive function, and justify its use and relevance in the CREST-H (hemodynamics) subset with cerebral hypoperfusion for hypothesized cognitive improvement with revascularization.Disclosure: Dr. Lazar has nothing to disclose.
