People with Huntington's disease usually die within 15 to 20 years of their diagnosis. The most common causes of death are infections (such as pneumonia) and injuries related to falls.
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.
The last symptoms in advanced stage Huntington's disease (HD) include immobility, inability to speak, and inability to eat without a feeding tube. People in this stage of the disease often require full-time skilled nursing care. The disease is usually fatal 15 to 20 years after symptoms begin.
The disease attacks areas of the brain that help to control voluntary (intentional) movement, as well as other areas. People living with HD develop uncontrollable dance-like movements (chorea) and abnormal body postures, as well as problems with behavior, emotion, thinking, and personality.

The mutant protein huntingtin causes neurodegeneration in the brain, particularly in the caudate nucleus and putamen. The mean age at onset is in the third and fourth decade of life and the disease duration about 15-20 years. Death usually results from respiratory complications.
The range of disease duration was between 2 and 17 years, the oldest living to age 91.
Huntington's disease (HD) is one of the most devastating diseases of mankind. It incapacitates patients by affecting their ability to move, think, and behave normally. It causes uncontrollable and disabling movements of the face, neck, trunk and limbs, loss of balance, and uncoordinated movements.
Huntington's Disease (HD) is not fatal in itself. People with HD have a shorter life expectancy and die of other life-threatening complications related to this disease. Pneumonia and heart disease are the two leading causes of death for people with HD.
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.”
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.
While treatments exist to manage the symptoms of the disease, nothing has proven to be curative – yet.
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.
After Huntington's disease starts, a person's functional abilities gradually worsen over time. The rate of disease progression and duration varies. The time from the first symptoms to death is often about 10 to 30 years. Juvenile Huntington's disease usually results in death within 10 years after symptoms develop.
When alcohol becomes a coping mechanism for Huntington's disease, that's when it becomes a problem. “With any neurodegenerative or medical disease, drinking a lot can certainly affect your balance and your gait,” says Dr. Oguh.
From the onset of symptoms, people with HD have a life expectancy of 10 to 25 years. HD is not evident at birth. In fact, symptoms will usually not appear until a person is between 35 and 55 years of age, and occasionally even later in life.
The youngest symptomatic child documented had an age of onset of 18 months,3 with other children developing symptoms in their teens, meaning that some individuals with JHD may now be in their twenties.
Myth 4: HD can skip generations. Fact: The HD gene mutation never skips a generation.
Huntington's disease is a progressive brain disorder caused by a single defective gene on chromosome 4 — one of the 23 human chromosomes that carry a person's entire genetic code. This defect is "dominant," meaning that anyone who inherits it from a parent with Huntington's will eventually develop the disease.
Mood and behavioral changes
Agitation, irritability, and aggression are other possible personality changes. Some patients may experience hallucinations and delusions that can severely affect their day-to-day interactions. Living with Huntington's can induce feelings of anxiety, depression, apathy, and frustration.
