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.
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.
LATE STAGE
Chorea may be severe, but more often it is replaced by rigidity, dystonia, and bradykinesia. Psychiatric symptoms may occur at any point in the course of the disease, but are harder to recognize and treat late in the disease because of communication difficulties.
Hospice referrals for Huntington's can be challenging because it's difficult to predict decline. Common end-of-life signals include significant weight loss, difficulty swallowing or breathing, recurrent aspiration pneumonia, and uncontrolled pain.
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.
Stage V: (11 - 26 years from illness onset)
Requires major assistance in financial affairs, domestic responsibilities, and all activities of daily living. Full-time skilled nursing care is required.
Stage 3: Late Intermediate Stage
Generally, the disease will have affected them enough that they will require assistance with everyday tasks. This stage will generally carry on for around five to sixteen years.
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.”
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.
Progress has been made in identifying possible ways of slowing down or halting the condition by "switching off" the faulty gene that causes it. Several treatments are now going through clinical trials. If they're found to be safe and effective, they might be available in several years' time.
Studies demonstrate increased motor activity during sleep (55, 80, 81), including periodic limb movements (37, 82) and behavioral disorders during REM sleep (27) in HD patients compared to subjects not suffering from HD. More movements during sleep occurred in HD patients compared to patients with PD (79).
When involuntary movements become more frequent, there is a chance the patient can get hurt. Also memory and speech may be affected more and lead to other problems. At this point an assisted living facility or memory care facility may be needed.
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 range of disease duration was between 2 and 17 years, the oldest living to age 91.
While the cause of the disease is known — a single mutated gene — there is no cure. “Our plan is to conduct human clinical trials that deliver stem cells to replace damaged brain cells, reducing levels of harmful proteins that build up in the brains of Huntington's disease patients.”
The Age of Persons Experiencing the Onset of HD Can Vary
About 10% have onset of motor symptoms after age 60 and 10% have Juvenile onset HD, where symptoms manifest before age 20.
Stage 4: Early advanced stage
A person in this stage of Huntington's cannot live independently. Some patients reside in their home with help from either family or professionals, while other individuals may decide that their needs will be better met at an extended care facility.
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.
Pneumonia and heart disease are the two leading causes of death for people with HD.
While there's no cure for Huntington's, there are medications that help control some symptoms. Some medications help suppress involuntary movements and some antipsychotic medications may assist in subduing the movements and help manage agitation and excessive mood swings.
They may lack inhibition, and do or say things that one would normally find embarrassing. People with Huntington's may also be less able to control their emotions, possibly leading to outbursts of screaming, swearing, slamming doors, hitting walls, or the like. Patterns of behavior can change as the disease progresses.
This disease often affects a person's ability to plan, make decisions, and process complex topics. But patients usually retain past memories, and are able to recognize people, objects, letters, numbers, and colors. They are often able to continue carrying out jobs that they have previously been doing for many years.
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.
Huntington's is a progressive disease. Once the symptoms appear, they continue and worsen over time. In most cases, they become noticeable between the ages of 30 and 50 and typically begin gradually. Although their onset and progression can vary from person to person, they fall into three basic categories.
