Differences in lateral hemispheric asymmetries of glucose utilization between early- and late-onset Alzheimer-type dementia

Am J Psychiatry. 1985 May;142(5):638-40. doi: 10.1176/ajp.142.5.638.

Abstract

Positron emission tomography with [18F]fluorodeoxyglucose revealed greater right than left hemispheric impairment of cortical glucose metabolism in patients with probable Alzheimer's disease who were younger than 65 but not in those over 65. This asymmetry was related to poor visuospatial performance.
