The authors used the Hamilton Rating Scale for Depression and a rating
of depressed mood to investigate the prevalence of depression in 55
patients with Alzheimer's disease, 37 patients with multi-infarct dementia,
and 30 nondemented comparison subjects. The prevalence of depressed mood
depended on the severity of dementia as measured by the Mini-Mental State
examination and was significantly lower among patients in more severe
stages of Alzheimer's disease but not among patients with severe
multi-infarct dementia.Abstract Teaser
