Event-Related Potentials and Cerebral Blood Flow in Idiopathic Parkinson’s Disease and Juvenile Parkinsonism
Juvenile parkinsonism (JP; onset age < 40 y. o.) has clinical charasteristics different from idiopathic parkinson’s disease (IPD; onset age ≥ 40 y. o.) (Yamamura et al., 1973). In IPD, mental deterioration occurs with progression of disease process. On laboratory examinations related to mental activity, abnormalities of event-related potentials (ERPs) and cerebral blood flow (CBF) have been reported in patients with IPD. However, cerebral function related to mental activity has not been fully studied in JP apparently because of fewer number of patients.
