Huntington’s disease is an inherited disease of the nervous system. It gradually destroys the nerve cells of the brain. There is no cure for
the nerve damage resulting from Huntington’s disease; it will last forever.
Huntington’s disease impacts a person’s functional and mental abilities, and usually results in movement, cognitive and psychiatric disorders. However, treatments available now can’t prevent the decline of the body functions.
Huntington’s disease is a rare disorder. Based on Huntington’s disease statistics, it is estimated that it affects about 30,000 people in the United States alone.
Huntington’s disease is caused by an inherited defect in a single gene. A person with one parent who has an abnormal copy of the gene, has a 50 percent chance of inheriting the gene and developing the disease.
The genetic mutation responsible for Huntington’s disease is different from many other mutations. An area within the gene is copied too many times. The number of repeated copies tends to increase with each generation.
There are two types of Huntington’s disease: adult onset and early onset.
Adult Onset
Symptoms of adult onset usually begin when people are in their 30s or 40s.
Initial symptoms include:
Symptoms that come out later include:
Early Onset
Symptoms of early onset one usually start to appear in childhood or adolescence. Early-onset Huntington’s disease causes mental, emotional, and physical changes, such as:

Psychiatric tests check your coping skills, judging abilities, emotional state, and behavioral patterns, signs of disordered thinking and evidence of substance abuse.
The imaging technologies may include electroencephalogram (EEG) tests, magnetic resonance imaging (MRI) scans and computed tomography (CT) scans.
Genetic tests may also help you decide whether or not to have children.
