MRI Assessment of Impaired Glucose Metabolism in Alzheimer's Disease

Completed

• Conditions: Alzheimer Disease

• Registration Number: NCT05402566
• Lead Sponsor: University of Aarhus

Brief Summary

Diseases of dementia are chronic, untreatable, and cause a massive burden of morbidity. In this proposal, we seek to tackle the problem of better, earlier, and more efficient diagnosis using deuterium metabolic imaging (DMI). The study is divided in two sub-studies: 1) optimization and simplification of DMI protocols, and 2) a cross-sectional study of DMI in Alzheimer's patients and healthy controls.
