Single-center Prospective Longitudinal Study of Taste in Patients With Cognitive Disorders at Different Stages of Severity (Isolated Cognitive Complaint, Minor or Major Neurocognitive Alzheimer-type Disorders) by Analysis of Gustatory Evoked Potentials

This study looks at how your sense of taste changes if you have memory problems, from mild to more severe Alzheimer's disease. Researchers hope to find early signs of Alzheimer's by studying taste, which could help with earlier diagnosis and better care.
