Clinical Trial Summary

Alzheimer disease is a frequent disease in the late ages that results in global alteration of cognitive functions. In which memory complaint can be isolated in the early stages. Physiopathology of neuronal degenerescence in Alzheimer disease is complex, two main histological lesions are known, amyloid plaques and neurofibrillar tangles. Beyond the histological knowledge, alterations of neuronal metabolism are described such as oxydative phosphorylation and glycolytic pathway. These metabolism alterations are involved in neuronal death. Multi-nucleus magnetic resonance spectroscopy is a non-invasive non-irradiant imagery technique already used in routine. This technic allows the phosphoenergetic pool assessment, that inform about cellular metabolism. The aim of the study is to explore the phosphorylated metabolism patterns as predictive biomarkers of cognitive decline in patients with a memory complaint diagnosed.

Outcome

Type Measure Description Time frame Safety issue
Primary phosphorylated metabolism profile assessment as predictor of cognitive decline in patients with memory complaint. correlation between brain phosphorylated metabolism (Pcr, ATP, PME, PDE, cho, NAA, Cr, PH) at the inclusion and MMSE on 2 years. ONE YEAR
Secondary Correlation between phosphorylated metabolite and final diagnostic of Alzheimer disease or not. Correlation between brain metabolite (Pcr, ATP, PME, PDE, cho, NAA, Cr, PH) and Alzheimer disease final diagnostic. ONE YEAR
Secondary Correlation between phosphoryled metabolite and variability of cerebro spinal fluid biomarkers Correlation between brain metabolite (Pcr, ATP, PME, PDE, cho, NAA, Cr, PH) and cerebro spinal fluid biomarkers (B-amyloid Tau protein and Phosphorylated-Tau Protein) ONE YEAR
Secondary Correlation between multinuclear magnetic resonance spectroscopy data and severity of cognitive dysfunction, at the inclusion and at one year. Correlation between brain metabolite (Pcr, ATP, PME, PDE, cho, NAA, Cr, PH) and MMS score at the inclusion and at one year. ONE YEAR
Secondary Evolution of multinuclear magnetic resonance spectroscopy data at one year and cognitive decline at one year. Comparison at the inclusion and at one year of brain metabolite (Pcr, ATP, PME, PDE, cho, NAA, Cr, PH) and MMS score. ONE YEAR
