[Memory deficit in Parkinson's disease. Precocious aging of recall processes].
In this study, the various components of the memory process were analysed in 25 non-demented parkinsonian patients (PP). A battery of tests was used to explore words, drawings and semantic organization of items. Results were compared with young (n = 22) and elderly (n = 11) healthy controls. Scores were correlated with the characteristics of Parkinson disease. Recall of words and drawings was significantly disturbed in PP. In contrast, the recognition of drawings and faces was not impaired. A high degree of interindividual difference in performance was observed; it was strictly correlated with age but not with the features of parkinsonism. A specific pattern of memory impairment can be described in parkinsonism, which would suggest and support the theory that different pathogenic mechanisms are involved in ageing and in parkinsonian patients.
