Symptoms of Huntington's disease include uncontrolled movement of the arms, legs, head, face and upper body, a decline in thinking and reasoning skills (memory, concentration, judgment and ability to plan and organize), alterations in mood, and obsessive-compulsive behavior.
Because of a discovery of the defective gene that causes Huntington's disease in 1993, a diagnostic genetic test was developed. The test can confirm that the defective gene for the disorder is the cause of symptoms in people with suspected Huntington's disease and can detect the defective gene in people who don't yet have symptoms.
Huntington's disease is more of a rare disease because it affects an estimated 3 to 7 per 100,000 people of European ancestry. It's even more rare in countries such as Japan, China, etc.
