Isotopic Imaging for Prodromal Alzheimer's Disease

Completed

• Conditions: Alzheimer Disease

• Registration Number: NCT01231295
• Lead Sponsor: Centre Hospitalier Universitaire de Nīmes

Brief Summary

The primary objective of this study is to characterize cerebral metabolism modifications using 18F-FDG PET technology and perfusion with 99MTC-ECD SPECT in patients with prodromal Alzheimer's Disease drawn from a high risk population. We also compare PET and SPECT imaging within this framework, and search for optimal diagnostic thresholds.
