Brief 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 Measures

Primary Outcomes (1)

  • 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 Outcomes (4)

  • Correlation between phosphorylated metabolite and final diagnostic of Alzheimer disease or not.

    ONE YEAR

  • Correlation between phosphoryled metabolite and variability of cerebro spinal fluid biomarkers

    ONE YEAR

  • Correlation between multinuclear magnetic resonance spectroscopy data and severity of cognitive dysfunction, at the inclusion and at one year.

    ONE YEAR

  • Evolution of multinuclear magnetic resonance spectroscopy data at one year and cognitive decline at one year.

    ONE YEAR
