Hippocampal formation glucose metabolism and volume losses in MCI and ADS De Santi
Department of Psychiatry, New York University School of Medicine, New York, NY, USA
Neurobiol Aging 22:529-39. 2001..These cross-sectional data show that in MCI hippocampal formation changes exist without significant neocortical changes. Neocortical changes best characterize AD. In both MCI and AD, metabolism reductions exceed volume losses...
