Remotivation therapy and Huntington's disease.

Huntington's disease (HD) is a genetic, autosomal dominant, neurodegenerative disorder for which there is no known cure. Because remotivation therapy (RmT) has been effective in other neurological conditions and because of the lack of current efficacious treatments for HD, RmT may be a beneficial therapy for persons suffering from the disease. By cultivating a more fertile environment, RmT leads to increased self-awareness, self-esteem, and an improved quality of life, even in late-stage HD. Two recent studies using animal models suggest that exposure of transgenic HD mice to a stimulating, enriched environment helped to prevent the loss of cerebral volume and delay the onset of motor disorders. Six case studies are presented that demonstrate improved physical, mental, and social functioning in persons with HD when a more stimulating environment is provided.
