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.
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.
Early symptoms
The first symptoms of Huntington's disease often include: difficulty concentrating. memory lapses. depression – including low mood, a lack of interest in things, and feelings of hopelessness.
The early intermediate stage of Huntington's can last between three and 13 years from disease onset. During this stage, patients begin to experience impairments in day-to-day living. For instance, people in the early intermediate stage may be able to do their job, but at a lower capacity.
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.
Noticeable changes in personality. Involuntary movements (chorea) and unsteady gait. Slurred speech. Difficulty swallowing and significant weight loss.
Lots of people at risk of Huntington's disease decide they'd rather not know until any symptoms appear. If you do want to know, ask your GP for a referral to a genetic counsellor. You'll have several appointments with the counsellor.
Familial prion disease may produce a diverse range of phenotypes, even within the same pedigree. It may resemble HD with prominent personality change, psychiatric symptoms and cognitive decline, chorea, rigidity, and dysarthria. Limb and truncal ataxia and seizures may be present.
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 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 Age of Persons Experiencing the Onset of HD Can Vary
While most people with HD develop the motor symptoms in their forties and fifties, subtle changes may arise much earlier.
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.
Medicines can help reduce some of the problems caused by Huntington's disease, but they don't stop or slow down the condition. These include: antidepressants for depression. medicines to ease mood swings and irritability.
In addition to suggesting that creatine could slow the progression of Huntington's disease, these results also imply that neuroimaging may provide a useful way to measure disease modification when studying other potential treatments.
Who does Huntington's disease (HD) affect? 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.

There is no cure, and it is fatal. People are born with the defective gene that causes the disease. But symptoms usually don't appear until middle age. Most cases of Huntington's disease are diagnosed between the ages of 30 and 50.
In early stage HD, individuals are largely functional and may continue to work, drive, handle money, and live independently. Symptoms may include minor involuntary movements, subtle loss of coordination, difficulty thinking through complex problems, and perhaps some depression, irritability, or disinhibition.
Huntington's disease affects approximately 30,000 people in the United States. If left untreated, it can lead to serious liver disease, central nervous system issues and death.
Early signs and symptoms can include irritability, depression, small involuntary movements, poor coordination, and trouble learning new information or making decisions. Many people with Huntington disease develop involuntary jerking or twitching movements known as chorea.
Pneumonia and heart disease are the two leading causes of death for people with HD.
Symptoms typically emerge from age 30 to 50, but also can develop in children and older adults. Late-onset Huntington's, characterized by some as emerging after age 5o and others after age 60, is thought to be less severe than earlier onset Huntington's.
For individuals who are at risk of carrying the HD gene, testing can be performed before symptoms occur. Information from brain scans such as computed tomography (CT), electroencephalography (EEG) and magnetic resonance imaging (MRI) may be reviewed as part of the diagnosis.
