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.
Huntington's disease is an autosomal dominant disorder, which means that a person needs only one copy of the nontypical gene to develop the disorder.
It gradually kills nerve cells in the brain. This slowly deteriorates a person's physical and mental abilities. The disease is genetic, which means it is inherited from your parents. There is no cure, and it is fatal.
during the time surrounding death. For the purpose of this fact sheet, the beginning of end-of-life in HD is determined as the stage when the person affected has little control over movement, is bedbound, unable to communicate, unable to eat and drink on his/her own and experiences severe chorea or extreme rigidity.
Pneumonia and heart disease are the two leading causes of death for people with HD.
Some common end-of-life symptoms include significant weight loss, episodes of fever, respiratory distress and sleeping or deep unresponsiveness for most of the day.
People can start to show the symptoms of Huntington's disease at almost any age. Most will develop problems between the ages of 30 and 50. The condition gradually gets worse for around 10-25 years, until the person dies.
Weight loss can make symptoms worse and weaken the patient's immune system, making them more vulnerable to infections and other complications. Huntington's disease itself is not usually fatal, but it can lead to choking, pneumonia, or other infections that can lead to death.
Stage IV: (9 - 21 years from illness onset)
Requires major assistance in financial affairs, domestic responsibilities, and most activities of daily living. For instance, comprehension of the nature and purpose of procedures may be intact, but major assistance is required to act on them.
Nine patients have died, and seven have been lost to follow up. The range of disease duration was between 2 and 17 years, the oldest living to age 91.
There have been reports that juvenile onset Huntington's chorea is almost always inherited from the father, and that late-onset Huntington's chorea is inherited more often from the mother than from the father.
In Huntington's advanced stage, patients are totally dependent on others for their care. They can't walk or communicate with their loved ones, although they are generally able to understand what is being said and who everyone is.
Huntington's disease (HD) is an autosomal dominant neurodegenerative disorder that usually starts in mid-adult life. The clinical disease progresses to death over an average of 20 years.
Researchers believe this long protein damages and kills brain cells. Anyone who inherits the gene will eventually develop HD symptoms. The exact age when symptoms appear varies. Often, HD symptoms start earlier in each new generation than in the previous generation.
The disease gets worse over time. Early signs of HD can vary, but often include mild clumsiness or problems with balance or movement, cognitive or psychiatric symptoms (problems with thinking or emotion), and changes in behavior.
The most painful conditions in Huntington's, said Achterberg, are limb pain, headache, abdominal pain and fractures. “I think we should do more work in validation of pain tools, including observational pain instruments,” he said. “And for clinicians, I suggest you be especially aware of abdominal pain.”
Huntington's disease treatment research
“A recently concluded trial demonstrated a once-a-day medication, valbenazine, can improve chorea symptoms in Huntington's disease and is currently awaiting FDA approval,” noted Forbes.
No treatments can alter the course of Huntington's disease. But medications can lessen some symptoms of movement and psychiatric disorders. And multiple interventions can help a person adapt to changes in abilities for a certain amount of time.
Rarer causes of dementia. Huntington's disease is an inherited genetic condition that causes dementia. It causes a slow, progressive decline in a person's movement, memory, thinking and emotional state. Huntington's affects about 8 in every 100,000 people in the UK.
Research has indicated that in Huntington's disease the person's cognitive processes are also affected and get progressively worse over the years with some people going onto develop dementia in the later stages of Huntington's.

Pneumonia: Difficulty swallowing and decreased mobility can increase the risk of pneumonia, including aspiration pneumonia. Infections: Infections can develop as a result of the overall decline in health and as a result of diminished self-care.
Agitation can occur at any time during the course of the disease. Agitation is defined as inappropriate behavior in a particular context characterized by excessive motor or verbal activity that may include physically aggressive behavior, restlessness, or pacing [1].
The primary site of neuron loss in HD is the striatal part of the basal ganglia, with striatal projection neurons being nearly completely lost in advanced HD. Early dysfunction and late loss of cortical neurons is prominent as well.
