Abstract
Correct classification of patients with dementia is pertinent to proper interpretation of research findings. However, the history of Alzheimer's disease (AD) is characterized by a continuing debate on its nosological status. Cerebrovascular pathology, Lewy bodies, or hippocampal sclerosis in combination with neuropathological signs of AD of only limited severity results in a disease that is essentially different from severe, purely degenerative AD. The clinical signs, course of the disease, and pathological correlates in elderly patients suffering from “mixed dementia of the Alzheimer type,” may differ from those with “purely degenerative Alzheimer's disease” as encountered in relatively young patients. Both clinicians and researchers have much to gain from a perspective that acknowledges the differences between these subgroups of AD patients. It may provide a more realistic perspective, and it holds promise for new opportunities for prevention and treatment.
