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.
Symptoms of Huntington's disease usually develop between ages 30 and 50, but they can appear as early as age 2 or as late as 80. The hallmark symptom of Huntington's disease is uncontrolled movement of the arms, legs, head, face and upper body.
Stage 1: Early stage
The early stage starts when a person first begins experiencing motor symptoms, and can last up to eight years from disease onset. At this stage, motor symptoms are not debilitating.
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.
The Age of Persons Experiencing the Onset of HD Can Vary
People with HD show a wide range of symptoms at the onset of the disease. While most people with HD develop the motor symptoms in their forties and fifties, subtle changes may arise much earlier.
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.
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.
Huntington's disease is caused by a faulty gene. Cells in parts of the brain are very sensitive to the effects of the faulty gene. This makes them function poorly and eventually die. A parent with the Huntington's disease gene has one good copy of the gene and one faulty copy.
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.
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.
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.
As the disease progresses, a variety of motor, emotional/behavioral, and cognitive symptoms are experienced, including unsteadiness, trouble holding onto things, trouble walking, changes in sleeping patterns, delusions and hallucinations, intellectual decline, and memory loss.
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 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.”
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.
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.
On neuroimaging atrophy of the corpus striatum involving the caudate and putamen is seen. This change generally proceeds from medial to lateral and dorsal to ventral. These changes are better appreciated on MRI than on CT.
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.
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.
Although not directly related to HD, stress is nevertheless related to the progression of the disease because it adds to the neurodegeneration that is already taking place. Chronic stress can alter nerve cells, brain structure, and brain function.
It's possible to develop HD even if there are no known family members with the condition. Around 10% of people with HD don't have a family history.
Research studies have suggested that exercise is beneficial for reducing symptoms and maximizing function in persons with HD. Maintaining a healthy heart is important to the health of all persons, no matter their disability. Persons with HD should engage in aerobic activities ideally for at least 150 minutes a week.
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.
