Forty‐eight patients with a clinical diagnosis of Alzheimer's disease, 30 patients with cerebrovascular dementia, and 48 normal controls were assessed with a battery of neuropsychological tests designed to measure the following cognitive processes: orientation to time and place, memory, visual‐perceptual and constructional skills, language, conceptualization, attention, and executive functions (planning, self‐regulation and fine motor coordination). The differences detected were in orientation to time and place, in immediate and delayed recall of a short story, and in naming in which the patients with Alzheimer's disease were significantly disadvantaged. Vice versa, in attention processes, self‐regulation, planning, and fine motor coordination tasks the patients with cerebrovascular dementia were more severely impaired; these disturbances resemble some of those occurring in frontal lobe syndromes.
