Huntington's Disease (HD) is a neurological degenerative disorder that affects the central nervous system, causing progressive impairments in cognitive function, motor skills, and mental health. The disease is caused by a faulty gene that produces an abnormal form of a protein called huntingtin.
The disease is inherited in a dominant fashion, which means that each child of an affected parent has a 50% chance of inheriting the defective gene and therefore developing the disease. The symptoms of HD usually appear in midlife, between the ages of 35 and 50, but can also occur at any age. Common features of the disease include motor disturbances, cognitive impairment, and psychiatric symptoms such as depression, irritability, and anxiety.
At present, there is no known cure for HD, and treatment is aimed at managing symptoms and improving quality of life. Medications are used to alleviate symptoms such as motor impairments and mental health issues, and physical therapy and occupational therapy can help maintain mobility and independence. As the disease progresses, patients may require extensive support and care, including assistance with daily living activities.
Research in HD is ongoing, and there is hope for future treatments. Recent advances in understanding the biology of the disease have led to the development of new therapeutic strategies targeting the underlying mechanisms of HD. Studies have shown that RNA-targeted therapies, gene editing tools, and stem cell-based approaches can all be used to modify the disease-causing gene or to replace the diseased cells with healthy cells. While more research is needed to fully understand the potential of these treatments, the future looks promising for HD patients and their families.
