Male Alzheimer's disease patients, studied with 18-fluoro-2- deoxyglucose
positron emission tomography while performing a verbal memory test, showed
a right-greater-than-left asymmetry of cortical metabolism that tended to
be greater than that in healthy, age-matched control subjects. This
asymmetry was absent in female patients, preliminarily suggesting a
propensity for left hemispheric involvement in the Alzheimer's disease
process in males.
