title: Ageing and Parkinson's disease.
abstract: Based on the examination of 400 patients suffering from Parkinson's disease, the main symptoms of motor and brain ageing have been underlined. Motor ageing is evidenced by the importance of akinesis, while rigor and quaking are limited, and by the arrival of dystonic attitudes which tend to last. Brain ageing is revealed by memory disturbances, mental disorders and delusions without phasic or praxis troubles. The comparative study of different types of dementia did not allow clinical or anatomopathological confirmation.
