End-stage Huntington's disease (HD) is the final, most advanced stage where individuals become completely dependent, often bedridden, nonverbal, and unable to perform basic self-care, requiring 24/7 assistance, with movement often shifting from chorea to rigidity, and complications like pneumonia or falls leading to the end of life, though awareness and comprehension often remain.
Stage III: (5 - 16 years from illness onset)
Totally unable to engage in employment and requires major assistance in most basic functions: financial affairs, domestic responsibilities, and activities of daily living.
The clinical characteristics of HD include involuntary movement, behavioral abnormalities, personality changes, and dementia. In addition to motor and cognitive impairments, some patients show micturition symptoms, especially urinary incontinence.
At this stage, a person with Huntington's is no longer able to do their own personal care and domestic responsibilities, and will have difficulty with mobility, needing to be in a chair or bed most of the time. Swallowing may be difficult and there may be significant weight loss.
Huntington's chorea, also called “Huntington's disease” or "Morbus Huntington", is a dominantly inherited disorder of the brain. It was named after the US physician George Huntington, who was the first to scientifically describe the disease in 1872.
It is important to remember that these outbursts of anger are commonly the result of the brain changes in HD, and the person with HD may not understand that you are trying to help them. These brain changes can make it difficult or impossible for someone with HD to view situations from the perspectives of others.
And for social and cultural as well as medical and scientific reasons, it played a far more important role in defining the discrete clinical entity that soon came to be known as 'Huntington's chorea' and by the late 1960s, as 'Huntington's disease'.
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.
Key signs 2 weeks before death at the end-of-life stages timeline: Extreme fatigue and increased sleep. A marked decrease in appetite and fluid intake. Irregular breathing patterns (Cheyne-Stokes breathing)
Previous studies into the cause of death in HD have shown that the most frequent primary cause of death in HD is pneumonia.
Huntington disease can have multiple effects on the bladder, which can significantly impact an affected individual's quality of life (QoL). As the disease progresses, a patient may experience a wide range of lower urinary tract symptoms including urgency, incontinence, or even development of neurogenic bladder.
The term “latchkey incontinence” is often used to describe a person's constant and urgent need to urinate the moment they get home. Although the term is popular, it is not generally used in medical terminology. A person with latchkey incontinence is most likely experiencing symptoms of an overactive bladder or OAB.
The damage to nerves in the brain alters messages that travel from the brain to other parts of the body. Those altered messages cause movement disorders (dyskinesias) and other symptoms of Huntington's disease. Involuntary jerking movements (chorea) are the symptoms most often associated with Huntington's disease.
Palliative care can make a big difference. The palliative care team can manage symptoms and side effects of treatment. They can provide medications to relieve muscle spasms, calm nervousness and manage shortness of breath. Sometimes feeding tubes are necessary for nutrition if swallowing becomes difficult.
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.
Everyday tasks such as eating, dressing, and bathing can become increasingly difficult for individuals with Huntington's Disease. If you notice your loved one consistently struggling with these essential activities, it's a clear sign they need additional support to maintain a fulfilling life.
But the body tries valiantly. The first organ system to “close down” is the digestive system.
Hospice Isn't About Giving Up
It's not a place to speed up the process of dying. A doctor suggesting hospice does not mean they're giving up on providing care and medical treatment. It's end-of-life care, but this doesn't mean giving up hope. It means shifting focus from curative treatments to comfort and support.
The following symptoms are often a sign that the person is about to die:
How do you know someone is in their final hours?
Huntington's disease targets cells in two brain regions for destruction: the cortex and the striatum. Far more neurons die in the striatum — a cerebral region named after its striped layers of gray and white matter.
The movement disorders related to Huntington's disease may cause movements that can't be controlled, called chorea. Chorea are involuntary movements affecting all the muscles of the body, specifically the arms and legs, the face and the tongue. They also can affect the ability to make voluntary movements.
During a recent conversation, Dylan's visit with ailing singer-songwriter Woody Guthrie came up. My friends hadn't realized that Guthrie had Huntington's disease — which they knew as the same disease that's affected several generations of my family. (I recently tested negative for Huntington's, thankfully.)
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.
Speech changes are typically mild initially but can get worse over time. Speech can become slurred (if muscles in the face and tongue become weak) or lose its natural rhythm and sound 'jerky' (if you have difficulty coordinating your breathing with speech).
