Abstract:
Objective To investigate the changes of visual evoked potentials (VEP) in patients with Parkinson’s disease (PD). Methods Pattern reversal checkerboard VEP and the unified Parkinson’s disease rating scale (UPDRS) were evaluated in 69 patients with PD and 61 healthy controls. The 69 patients and 61 healthy controls were divided into an aged group (≥60 years old) and a non aged group (0.05). Conclusions VEP reflected objectively the patients’ electrophysical changes of the visual pathway due to dopamine changes and it may be helpful in PD diagnosis.
