Abstract
We administered three cognitive tests (the Mini Mental State Examination, the Cognitive Capacity Screening Examination, and the Blessed Information-Memory-Concentration test) and three behavioral scales (the Blessed Dementia Scale, the Gottfries-Bråne-Steen scale, and the Sandoz Clinical Assessment Geriatric) to 41 patients with a clinical diagnosis of “probable” Alzheimer's disease (NINCDS-ADRDA criteria). The six measures demonstrated good reliability and high intercorrelation values. These findings provide further evidence for the strength of relationship between cognitive and behavioral measures in Alzheimer's disease.
