Huntington disease (HD) is a hereditary neurodegenerative disorder causing impairment in movement, behavioral dysfunction and dementia. The movement disorder is mainly characterized by chorea (involuntary movements) and a progressive loss of voluntary movement causing a substantial functional impairment over time. The study will assess the long-term safety of pridopidine and the treatment effects during long-term, open-label treatment.
