What is Huntington’s disease?

Huntington’s disease is a progressive brain disorder in which parts of the brain stop working properly over time 평가원 수능 다운로드. It involves a loss of the ability to think properly, to regulate emotions and control movements. Adult-onset Huntington’s disease is the most common form of this disorder.

Early signs and symptoms may include irritability, depression, small involuntary movements, poor coordination, trouble learning new information or a difficulty in making decisions.

Many people with Huntington’s disease develop involuntary jerking or twitching movements, known as chorea. As the disease progresses, these movements become more pronounced. When this happens, they may have trouble walking, speaking, and swallowing.

People with this disorder also suffer changes in personality and a decline in thinking and reasoning abilities.

Symptoms include:

  • Personality changes, mood swings and mental health conditions like depression.
  • Forgetfulness and impaired judgment.
  • Walking unsteadily and involuntary movements (chorea).
  • Slurred speech, difficulty in swallowing and weight loss.

Risk factors

The condition has a strong genetic component. If you have the Huntington’s disease defect gene, you’ll develop the disease at some point. Huntington’s disease is known as an autosomal dominant disorder, which means you only need one copy of the gene to be at risk.


To date, there is no cure for Huntington’s disease but there are ways to treat it’s symptoms. This includes medication to reduce uncontrolled movements and psychiatric disorders. There are also certain therapies that help, alongside medication. The treatment that you receive will depend on the stage of the disease and on your own response to medication. It is likely to change over time.

Haloperidol and tetrabenazine also provide some relief from hallucinations and delusional thoughts brought on by the condition.
