Abstract

The object of this study is to investigate whether or not there are clinical signs and symptoms in patients with dementia that, by themselves or jointly, can be associated with the pathological diagnosis of Alzheimer's disease. Twelve patients with dementia were studied, in whom the clinical diagnosis of Alzheimer's disease was made according to established criteria. A sample of leptomeninges, cortex and subcortical white matter was obtained from each patient and was processed for light and electron microscopy. In the cases in whom neuritic plaques and neurofibrilary tangles were present, pathological changes were quantified. The diagnosis of Alzheimer's disease was confirmed in 5 cases, whereas in 3 patients spongiform encephalopathy was present. In the remaining patients, the number of neuritic plaques was within normal limits for the age of the subjects. Comparison of the data in Alzheimer (n = 5) and non-Alzheimer (n = 7) groups showed an increased, statistically significant incidence of acalculia, abnormalities of judgment, impairment of abstraction and primitive reflexes in the former. Although good fitting models were obtained, none achieved perfect discrimination. The model that included alterations of judgment and acalculia gave the best fit.
