Huntington disease (HD) is a genetic problem of the brain. It causes the body to move in ways that the person cannot control. It also causes thinking problems that get worse over time.


HD is caused by a faulty gene. All people who inherit the faulty gene may get HD.

Risk Factors

The chance of getting HD is higher in those who have people in their family who have it.


Problems often start between 30 to 50 years of age. They are mild at first before they get worse.

Problems may be:

  • Changes in eye movements
  • Moving without control
  • Jerking movements of the arms, legs, face, or belly
  • Problems making decisions
  • Irritability
  • Lack of emotion
  • Mood swings
  • Problems walking and swallowing


The doctor will ask about your symptoms and health history. You will be asked whether you have other people in your family with HD. A physical exam will be done. Cognitive tests may also be done.

Blood tests will be done to look for the faulty gene.

Images may be taken to support the diagnosis. This can be done with:

MRI Scan of the Brain

There is no cure for HD. Symptoms can only be managed.


Medicine may be given to ease body movements. These may be:

  • Antipsychotics
  • Tetrabenazine


Counseling and support groups can help a person learn how to cope with HD.


HD cannot be prevented in a person who has the faulty gene.
