Huntington's disease is a genetic disorder that causes movement, cognitive, and emotional issues and deteriorates over 15-17 years from onset until death. Maintaining quality of life is important as there is no cure. Nursing care involves educating families, addressing emotional needs, and focusing on maintaining function through therapies, managing symptoms like dysphagia and dysarthria, and individualizing care based on patient needs including nutrition, mobility, skin integrity, and spiritual/emotional support. Support groups and recreational activities can also help patients and families cope with the disease.
