Symptoms most often develop between the ages of 30-50 years. Symptoms are mild at first and are often barely noticeable, but usually worsen over 15-20 years.
Abnormal body movements that worsen over time, may include:
- Sudden jerks or uncontrolled movements of the limbs or trunk
- Facial grimacing
- Continuous need to turn head and shift gaze
- Walking that is unsteady or dance-like
Gradual deterioration or loss of intellectual abilities may include:
- Difficulty with eating and swallowing, which may result in weight loss
- Difficulty dressing, sitting, and caring for oneself
- Grunting or poor articulation of speech
Mental function and behavior problems may include:
- Trouble with attention and awareness
- Confusion or disorientation
- Loss of memory
- Loss of judgment
- Loss of ability to think rationally
- Irritability and moodiness
- Depression (common)
- Social withdrawal or antisocial behavior
- Irresponsible behavior
- Personality changes
- Psychosis—a severe emotional and behavioral disorder that often interferes with a person's ability to relate to others and to function in daily life
- Paranoia—a mental disorder that involves feelings of being watched, followed, or harmed by others
- Hallucinations—the perception of a thing or person that is not present
Ultimately, HD can:
- Cause the loss of the physical and mental ability to care for oneself
- Cause severe disability, making full-time or nursing home care necessary
- Result in death, often due to a fall or pneumonia
You will be asked about your symptoms and medical history (including family medical history). A physical exam will be done.
Your bodily fluids may be tested. This can be done with blood tests.
Images may be taken of your bodily structures. This can be done with:
- MRI scan
- CT scan
- SPECT scan

There is a test that can determine if a person has inherited the gene for HD. This test may help to make the diagnosis of HD. It may also help to determine if a person has inherited the HD gene before symptoms appear. Genetic counseling is advised before taking this test to review risks and benefits.
There is no cure for HD. Treatment aims to help control symptoms.
Drugs can help control abnormal movements and emotional symptoms of HD. These include:
Staying physically active helps people with HD to function better and longer. Often, physical and occupational therapy may be of some benefit.
