Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The aim of the PI-PEG study is to explore the taste functions of the following 3 groups of participants:

* healthy volunteers
* patients with early Parkinson's disease
* patients with incipient Lewy body disease.

To this end, the results obtained from taste evoked potentials in each of the 3 groups of participants will be compared with each other and with different nutritional, motor and cognitive data.

This study could reveal a difference in cortical processing of gustatory sensory information between patients who have had idiopathic Parkinson's disease progressing for 3 years or less, and patients who have had Lewy body disease progressing for 3 years or less. Indeed, a modification of taste evoked potentials (in terms of latencies) proportional to the degree of cerebral degeneration could be observed.
