Development of a New Neuroimaging Method Aimed to Differentiate Mnesic Abilities of Alzheimer and Depressed Patients

Not Applicable

• Conditions: Alzheimer Disease; Depression

• Registration Number: NCT02840045
• Lead Sponsor: Centre Hospitalier Universitaire de Besancon

Brief Summary

The purpose of this study is to use a new method to differentiate mnesic abilities of early alzheimer patients and patients with a depressive disorder.

This method is based on the recording of cerebral activity while patients listen to familiar, unfamiliar and newly-learned music.
