Huntington's Disease is a hereditary condition that causes the progressive breakdown of nerve cells in the brain. It typically manifests in mid-adulthood and leads to a range of symptoms, including movement disorders, cognitive decline, and emotional disturbances. The disease is caused by a mutation in the HTT gene, which results in the production of an abnormal protein that is toxic to brain cells. As the disease progresses, individuals may experience difficulties with coordination, changes in personality, and challenges with memory and judgment. While there is currently no cure for Huntington's Disease, treatments are available to help manage symptoms and improve quality of life for those affected.
