- Ratio of Inorganic Phosphate (Pi) Over Phosphocreatine (PCr): Pi/PCr [ Time Frame: visit 1 (baseline), visit 2 (after 1 month of treatment) ]
The Pi/PCr Ratio is a measure of brain metabolism and it is an index of mitochondrial oxidative regulation.
A 6-cm 31P transmit/receive surface coil (RAPID Biomedical GmbH, Rimpar, Germany) was used to collect free induction decays for 4 minutes at rest, 8 minutes during visual activation with 6-Hz red/black checkerboard flashes, and 8 minutes after stimulation. Subjects were able to focus on the flashes with a nonmagnetic mirror mounted above their eyes while all lights in the room were turned off. The Pi/PCr ratio was then calculated to determine brain response to cortical activation.
- Correlation Between Primary Outcome Measure and Clinical Parameters [ Time Frame: visit 1 (baseline), visit 2 (after 1 month of treatment) ]Correlating an improvement of brain energy profile with clinical parameters in Huntington patients such as the Unified Huntington's disease rating scale (UHDRS) and total functional capacity score (TFC).
