Study to Evaluate Music Therapy on Irritability and Impulsivity in Patients With Huntington's Disease (MUSIC-HD)

The participants will be recruited at the Clinical Investigation Center (CIC) of the University Hospital of Poitiers and will receive music therapy for 3 months. After the start of the musical intervention, 3 visits (at 1 month, 3 months and 6 months) will be performed by practitioners, nurses and neuropsychologist at the CIC. Participants will answer questionnaires : irritability (BITe and PBA-s sub-score), impulsivity (UPPS-P and Delay discounting task), anxiety (STAI-Y and HAM-A), and quality of life: H-QoL-I. Caregivers will be asked to rate the patient's irritability and anxiety using a Lickert scale from 0 to 10, and the patient's impulsivity with the ISDC.
