Left hemispheric reductions of regional cerebral blood flow (rCBF) correlate with measures of dementia severity in patients with Alzheimer's disease: a SPECT study.
Regional cerebral blood flow (rCBF) values were measured by single photon emission computed tomography (SPECT) in different regions of the brain in 27 patients with DAT. Significant correlations were found between rCBF in left parieto-temporooccipital regions and psychometric test scores. Patients with hemisphere asymmetry in SPECT performed worse on psychometric tests. SPECT did not permit prediction of or differentiation between depressive and psychotic symptoms.
