Pioglitazone Or Exercise to Treat Mild Cognitive Impairment (MCI)

Summary

The purpose of this study is to investigate novel treatments to delay progression to dementia in patients with mild cognitive impairment (MCI) and metabolic syndrome (MS). The hypothesis is that treatment with pioglitazone or endurance exercise training will improve, stabilize, or attenuate decline in cognitive function compared to controls. This study will also discover potential mechanisms for the improvements and determine the baseline prevalence of amnestic versus non-amnestic MCI.
