What is Huntington's disease and what does it do?

Overview. Huntington's disease is a rare, inherited disease that causes the progressive breakdown (degeneration) of nerve cells in the brain. Huntington's disease has a broad impact on a person's functional abilities and usually results in movement, thinking (cognitive) and psychiatric disorders.

What were your first symptoms of Huntington's disease?

The first symptoms of Huntington's disease often include:

  • difficulty concentrating.
  • memory lapses.
  • depression – including low mood, a lack of interest in things, and feelings of hopelessness.
  • stumbling and clumsiness.
  • mood swings, such as irritability or aggressive behaviour.

How long do you live with Huntington's disease?

Huntington's disease is a condition that stops parts of the brain working properly over time. It's passed on (inherited) from a person's parents. It gets gradually worse over time and is usually fatal after a period of up to 20 years.

What are the 5 stages of Huntington's disease?

5 Stages of Huntington's Disease

  • HD Stage 1: Preclinical stage.
  • HD Stage 2: Early stage.
  • HD Stage 3: Middle stage.
  • HD Stage 4: Late stage.
  • HD Stage 5: End-of-life stage.

Is Huntington's disease painful?

A large worldwide study on the prevalence of pain in Huntington's Disease (HD). The outcomes are pain interference, painful conditions and analgesic use. The prevalence of pain interference increases up to 42% in the middle stage of HD. The prevalence of painful conditions and analgesic use decrease as HD progresses.

Who is most at risk for Huntington's disease?

Who does Huntington's disease (HD) affect? Although anyone can develop HD, it tends to run in people of European descent (having family members who came from Europe). But the main factor is whether you have a parent with HD. If you do, you have a 50% chance of also having the disease.

Can Huntington's be prevented?

Huntington's disease is a genetic disorder. It cannot be prevented or avoided.

What should you watch for in a person with Huntington's?

How is Huntington's diagnosed?

To make a diagnosis of Huntington's disease (HD), a genetic test, using a blood sample, will be performed. This test is usually combined with a complete medical history and other neurological and laboratory tests. For individuals who are at risk of carrying the HD gene, testing can be performed before symptoms occur.

What happens to the brain during Huntington's disease?

In Huntington disease, parts of the brain that help smooth and coordinate movements degenerate. Movements become jerky and uncoordinated, and mental function, including self-control and memory, deteriorates. Doctors base the diagnosis on symptoms, family history, imaging of the brain, and genetic testing.

When is Huntington's disease detected?

Symptoms of Huntington's disease usually develop between ages 30 and 50, but they can appear as early as age 2 or as late as 80. The hallmark symptom of Huntington's disease is uncontrolled movement of the arms, legs, head, face and upper body.

Is Huntington's disease hard to diagnose?

It is possible to be tested for Huntington's disease before any symptoms appear, if there is a known family history of the disease. However, a diagnosis can be difficult if there are between 36 to 40 CAG repeats, as the disease may or may not develop in the person.

Is there a cure for Huntington's disease 2020?

There's currently no cure for Huntington's disease or any way to stop it getting worse. But treatment and support can help reduce some of the problems caused by the condition.

Does an MRI show Huntington's disease?

To conclude neuroimaging, particularly MRI, remains a cornerstone in the diagnosis and assessing the severity of Huntington's disease. Genetic testing can be used to confirm the diagnosis if the family history is not forthcoming.

Can a blood test detect Huntington's disease?

Tests to diagnose Huntington's disease

Sometimes you might also have a brain scan. A blood test to check for the Huntington's disease gene can confirm if you have the condition.

What body systems are affected by Huntington's disease?

Huntington's disease is an inherited (genetic) condition that affects the brain and nervous system. It is a slowly progressive condition that interferes with the movements of your body, can affect your awareness, thinking and judgement and can lead to a change in your behaviour.

Can Huntington's skip generations?

Huntington disease (HD) does not occur in one generation, skip the next, and then reoccur in a subsequent generation. However, HD may appear to skip a generation for one of the following reasons: Failure to recognize the disease in family members. Early death of a parent before the onset of symptoms.

Can a CT scan detect Huntington's disease?

Special blood tests can help your healthcare provider determine your likelihood of developing Huntington disease. A computed tomography (CT) scan of the head can evaluate the scope and scale of brain cell damage and loss of brain tissue.

Are headaches a symptom of Huntington's disease?

Depression and behavioral disorders

The most painful conditions in Huntington's, said Achterberg, are limb pain, headache, abdominal pain and fractures.

What does Huntington's disease look like on an MRI?

MRI. The most striking and best-known feature is that of caudate head atrophy. There is also, however, prominent putaminal volume loss which is usually not as easily recognized on visual inspection but seen well on morphometry . This is particularly the case in younger patients .
