[Senile Parkinsonism: its motor and psychological defects].

Abstract

25% of patients with Parkinson's disease demonstrate the first symptoms with 70 years. The deficiency of Tyrosinhydroxylase is the trigger of the decreased level of Dopamin in the basal ganglia. The implications are the typical symptoms (tremor, rigor and akinesia) and the psychopathological decompensations as depression, delirs and bradyphrenie.
