Summary
The purpose of this study is to assess the safety and benefit of risperidone for the treatment of chorea (involuntary movements) in Huntington's disease. Risperidone is commonly used in clinical practice to treat chorea, however, it has not been approved by the Food and Drug Administration (FDA) to treat chorea. This study will examine 1) whether the investigators see MRI changes with risperidone treatment and 2) whether sensors applied to the participants body can measure chorea and detect changes in chorea.
Eligibility Criteria

Exclusion Criteria
- Use of antipsychotic, levodopa, dopamine agonist, monoamine oxidase inhibitor or other disallowed medication in the 30 days prior to the baseline visit (see Section 4.2.5)*
