31P-MRS and Huntington Disease (PRO-MH)
The purpose of this study is to identify and quantify a brain energy deficit in Huntington patients, using 31P-RMN spectroscopy.

Masking: Open Label
Primary Purpose: Prevention
|Official Title:||31Phosphorus-Magnetic Resonance Spectroscopy and Huntington Disease|
- Brain energy deficit in Huntington patients [ Time Frame: one year ] [ Designated as safety issue: No ]
31P-MRS allows quantification of high-energy phosphate metabolites such as ATP and phosphocreatine.
Objective: to look at brain energy metabolism during rest and activation.
- Correlating a brain energy deficit with (i) biochemical parameters and (ii) clinical parameters in Huntington patients [ Time Frame: one year ] [ Designated as safety issue: No ]
Biochemical parameters include metabolites that we previously showed to be biomarkers in HD: branched chain amino acids and IGF1.
Clinical parameters include UHDRS and TFC.
