Abstract
Patients with Parkinson's disease (PD) commonly show olfactory deficits in the early stages of the disease. These deficits can be verified psychophysically or electrophysiologically using olfactory event-related potentials (OERP). While psychophysical olfactory function in PD patients can improve over time, the course of OERPs in PD has not yet been investigated.
