What research is being done on Huntington's disease?
Although HD attracted considerable attention from scientists in the early 20th century, there was little sustained research on the disease until the late 1960s when the Committee to Combat Huntington's Disease and the Huntington's Chorea Foundation, later called the Hereditary Disease Foundation, first began to fund research and to campaign for federal funding. In 1977, Congress established the Commission for the Control of Huntington's Disease and Its Consequences, which made a series of important recommendations. Since then, Congress has provided consistent support for federal research, primarily through the National Institute of Neurological Disorders and Stroke, the government's lead agency for biomedical research on disorders of the brain and nervous system. The effort to combat HD proceeds along the following lines of inquiry, each providing important information about the disease:
Basic neurobiology. Now that the HD gene has been located, investigators in the field of neurobiology-which encompasses the anatomy, physiology, and biochemistry of the nervous system-are continuing to study the HD gene with an eye toward understanding how it causes disease in the human body.
Clinical research. Neurologists, psychologists, psychiatrists, and other investigators are improving our understanding of the symptoms and progression of the disease in patients while attempting to develop new therapeutics.
Imaging. Scientific investigations using PET and other technologies are enabling scientists to see what the defective gene does to various structures in the brain and how it affects the body's chemistry and metabolism.
Animal models. Laboratory animals, such as mice, are being bred in the hope of duplicating the clinical features of HD and can soon be expected to help scientists learn more about the symptoms and progression of the disease.
Fetal tissue research. Investigators are implanting fetal tissue in rodents and nonhuman primates with the hope that success in this area will lead to understanding, restoring, or replacing functions typically lost by neuronal degeneration in individuals with HD.
These areas of research are slowly converging and, in the process, are yielding important clues about the gene's relentless destruction of mind and body. The NINDS supports much of this exciting work.
