Summary
Huntington's disease is a genetic disorder that causes the breakdown of nerve cells in the brain, which affects movement, thinking, and emotions. It leads to severe disability and eventually death. Symptoms usually start in middle age and worsen over time.
Huntington's disease is caused by a genetic mutation in the HTT gene, which leads to the production of an abnormal protein that damages brain cells. It is inherited from parents and has no environmental or behavioral risk factors.
Symptoms include involuntary movements, cognitive decline, and emotional changes. Complications can include pneumonia, heart disease, and injuries from falls due to muscle control loss. These symptoms worsen over 10 to 30 years.
Huntington's disease is diagnosed through genetic testing, which confirms the faulty gene. Imaging tests like MRI or CT scans assess brain changes. Neurological exams evaluate movement and cognitive function.
There is no cure for Huntington's disease, but treatments like tetrabenazine and antipsychotics manage symptoms. Genetic counseling helps at-risk individuals understand their risk. Prenatal testing can identify the faulty gene in embryos.
Regular exercise, a balanced diet, and stress management techniques like deep breathing can help manage symptoms. Exercise maintains mobility and mood, while a nutritious diet supports health. These actions improve quality of life.
Understanding the Disease
What is huntington's disease?
Huntington's disease is a genetic disorder that causes the progressive breakdown of nerve cells in the brain. It is caused by a faulty gene that leads to the gradual loss of brain function. This disease affects movement, cognition, and emotions, leading to severe disability and eventually death. Symptoms typically appear in middle age, and the disease worsens over time.
What causes huntington's disease?
Huntington's disease is caused by a genetic mutation in the HTT gene, which leads to the production of an abnormal protein that damages brain cells. It is an inherited condition, meaning it is passed down from parents to children. There are no known environmental or behavioral risk factors. The disease is fully understood to be genetic in origin.
Are there different types of huntington's disease?
Huntington's disease has two main forms: adult-onset and juvenile. Adult-onset is more common, with symptoms appearing in middle age. Juvenile Huntington's, which is less common, starts in childhood or adolescence and progresses more rapidly. Symptoms in juvenile cases often include stiffness, learning difficulties, and seizures.
What are the symptoms and warning signs of huntington's disease?
Symptoms of Huntington's include involuntary movements, cognitive decline, and emotional changes. These symptoms typically appear in middle age and worsen over 10 to 30 years. Unique patterns include chorea, which refers to jerky movements, and personality changes. Early diagnosis is crucial for managing symptoms and planning care.
What are the five most common myths about huntington's disease?
One myth is that Huntington's disease is contagious, which is false as it is genetic. Another is that it only affects older adults, but symptoms can start in middle age. Some believe it skips generations, but it does not. A myth is that lifestyle changes can cure it, but there is no cure. Lastly, some think it affects only movement, but it also impacts cognition and emotions.
Which types of people are most at risk for huntington's disease?
Huntington's disease most commonly affects people of European descent. Symptoms typically appear in middle-aged adults, around 30 to 50 years old. Both men and women are equally affected. The disease is less common in people of Asian and African descent. The genetic mutation is the primary mechanism for its prevalence in these groups.
How does huntington's disease affect the elderly?
In the elderly, Huntington's disease may present with more pronounced cognitive decline and less chorea, which refers to involuntary movements, compared to middle-aged adults. The progression might be slower, but complications like falls and infections are more common due to age-related frailty. Age-related brain changes can influence symptom presentation.
How does huntington's disease affect children?
In children, Huntington's disease, known as juvenile Huntington's, progresses faster than in adults. Symptoms include stiffness, clumsiness, and learning difficulties, unlike the chorea, which refers to involuntary movements, seen in adults. The rapid progression in children is due to the larger genetic mutation size, which accelerates the disease process.
How does huntington's disease affect pregnant women?
Pregnant women with Huntington's may experience worsened symptoms due to hormonal changes. Complications like weight loss and nutritional deficiencies can affect pregnancy. The stress of pregnancy can exacerbate emotional symptoms. Hormonal fluctuations and increased physical demands contribute to these differences.

How will I monitor huntington's disease?
Huntington's disease is monitored through regular neurological exams, cognitive assessments, and imaging tests like MRI. These help track changes in movement, thinking, and brain structure. Monitoring frequency varies, but typically occurs every 6 to 12 months. Regular check-ups help manage symptoms and adjust treatments as needed.
What are healthy test results for huntington's disease?
Routine tests for Huntington's include genetic testing, which confirms the presence of the faulty gene. Imaging tests like MRI or CT scans assess brain changes. There are no "normal" values for genetic tests; a positive result indicates the disease. Imaging may show brain atrophy, which refers to shrinkage, indicating disease progression. Regular monitoring helps manage symptoms.
Consequences & Complications
What happens to people with huntington's disease?
Huntington's disease is chronic and progressive. Symptoms worsen over 10 to 30 years, leading to severe disability. Without treatment, it can result in complications like pneumonia or heart failure. While there is no cure, therapies can manage symptoms and improve quality of life, slowing progression and reducing complications.
Is huntington's disease lethal?
Huntington's disease is progressive and can be lethal. It leads to severe disability and complications like pneumonia or heart failure, which can be fatal. Risk factors for lethality include advanced age and severe symptoms. While there is no cure, treatments can manage symptoms and reduce complications, improving survival.
Will huntington's disease go away?
Huntington's disease is progressive and does not go away. It worsens over 10 to 30 years. There is no cure, but it is manageable with treatments that control symptoms. The disease cannot remit on its own without treatment. Ongoing care is essential for maintaining quality of life.
What other diseases can occur in people with huntington's disease?
Common comorbidities of Huntington's include depression, anxiety, and sleep disorders. These are related to the brain changes caused by the disease.
