The diagnosis of Huntington's disease is based on the symptoms above. A doctor will also perform neurological tests to help confirm diagnosis. There is also a special blood test for Huntington's disease, which identifies a gene responsible for the disease. The test determines whether an individual is affected with the disease and what are the chances of passing the gene on to his child. There is currently no cure for Huntington's disease, but only symptomatic treatment available.
Some medications help to partially reduce and suppress the symptoms of excessive movements.
These medications are from phenothiozine, neuroleptic or benzodiazepine class of drugs. Other medications may be given to help relieve depression and other behavioral disturbances associated with the disease. These may be in the tricyclic antidepressant or in the serotonin class of drugs. So far there are no medications to reduce the progression of the disease. Currently there is a lot of research being done on Huntington's disease.
