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.
The advanced stage lasts between 11 and 26 years from disease onset. Patients with Huntington's at this late stage will need total support in daily activities from professional nursing care.
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.
Common end-of-life signals include significant weight loss, difficulty swallowing or breathing, recurrent aspiration pneumonia, and uncontrolled pain.
Stage 5: Advanced Stage
The fifth and final stage is when the disease will be more severe, and it's likely that the individual will require care 24/7. They will likely be immobile, unable to communicate and find it extremely difficult to perform basic motor functions such as swallowing.
Stage IV (Late Stage HD)
The progressive breakdown of nerve cells in late-stage Huntington's disease results in severe motor symptoms, including extreme difficulty with voluntary movements, severe involuntary movements, abnormal slow movements, rigidity, and speech impairment.
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 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.

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.
The range of disease duration was between 2 and 17 years, the oldest living to age 91.
The most common sleep problems reported by HD patients include insomnia, difficulties in falling asleep, frequent nocturnal awakenings, and excessive daytime sleepiness.
Huntington's patients are often irritable and angry. They may feel frustrated, become stubborn and lose their tempers, and sometimes these feelings result in violent outbursts.
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 (HD) is an inherited disorder that causes nerve cells (neurons) in parts of the brain to gradually break down and die. The disease attacks areas of the brain that help to control voluntary (intentional) movement, as well as other areas.
Huntington's disease is a condition that damages nerve cells in the brain causing them to stop working properly. It's passed on (inherited) from a person's parents. The damage to the brain gets worse over time. It can affect movement, cognition (perception, awareness, thinking, judgement) and mental health.
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.
(For more information on Complications of HD, click here.) It is important to know that stress can lead to complications and the worsening of symptoms in people with HD.
Surprisingly, many people with Huntington's disease aren't aware that the involuntary movements are happening, or don't notice them as much as other people do. That's because Huntington's disease can affect people's awareness of their own bodies.
