Huntington's Disease Knowledge Assessment

Huntington's disease (HD) is a genetic disorder causing the breakdown of nerve cells in the brain, leading to physical and mental decline. Symptoms include mood swings, involuntary movements, and cognitive impairment, often appearing between ages 30 and 50. HD is caused by a DNA mutation with an expanded CAG repeat in the Huntington gene. The Huntington's Disease Society of America (HDSA) supports affected individuals through research, advocacy, and community services.
