While Huntington's disease is a stressful experience with an uncertain prognosis, it's not a reason to give up on life. It's possible to treat some of the symptoms and try to lead a healthy life for as long as possible. If you've been diagnosed, you don't need to let the disease take over.

What is the most common treatment for Huntington's disease?
Xenazine (tetrabenazine) is the only medication specifically approved for Huntington's chorea. Others, such as antipsychotics and benzodiazepines, have also demonstrated a benefit and can be used off-label. Physical therapy can help maintain mobility and prevent falls through tailored exercises for the patient.
How Does gene therapy work for Huntington's disease?
However, in the case of Huntington's disease, the goal is to use gene therapy to limit the production of the toxic huntingtin protein. Less toxic protein in the brain would mean a slower breakdown of neurons. These genetic instructions are delivered to cells using vectors.
Can Huntington's disease be prevented or treated?

How Does gene therapy work?
With gene therapy, doctors deliver a healthy copy of a gene to cells inside the body. This healthy gene may replace a damaged (mutated) gene, inactivate a mutated gene or introduce an entirely new gene. Carriers, called vectors, transport these healthy genes into cells.

On average, most people begin developing features of HD between ages 35 and 44. Signs and symptoms vary by stage and may include: [2] [3]
How many times does the HTT gene repeat?
This segment is made up of three DNA building blocks that repeat multiple times in a row. The CAG segment in a normal HTT gene repeats about 10 to 35 times. In people with HD, it may repeat from 36 to over 120 times.
What causes HD in humans?
In rare cases, HD is caused by a new ( de novo) mutation in the HTT gene, in which case the disease occurs for the first time in the affected person and is not inherited from a parent. [2] As HD is passed through generations, the size of the mutation in the HTT gene (called a trinucleotide repeat) often increases.
What causes HD?
It is caused by changes ( mutations) in the H TT gene and is inherited in an autosomal dominant manner. Treatment is based on the symptoms present in each person and may include various medications. [1] [2] There is also a less common, early-onset form of HD which begins in childhood or adolescence.
How long does HD last?
The duration of the disease (from onset until death) varies considerably, with an average of approximately 19 years. Most people with HD survive for 10-25 years after the onset of symptoms. The average age at death ranges from 51-57 years, but the range may be broader.
Is Huntington disease progressive?
Huntington disease (HD) is progressive, eventually leading to disability and death (usually from a coexisting illness or infection). However, the disease affects everyone differently; the age of onset, specific symptoms, and rate of progression varies for each person with HD.
Preclinical Stage
The preclinical stage of a disease is a period when the disease can be detected through screening or biological testing, but there are no obvious physical symptoms yet. During this time, damage can occur at the cellular level, but there is not enough damage yet for a person to notice it in their daily life.
Early Stage
During the preclinical stage of HD, neurologic damage occurs but you will not have any noticeable physical signs. As cells are gradually destroyed, the symptoms slowly begin to appear in your 30s to 50s.
Early Intermediate Stage
In the early intermediate stage (stage II) of HD, the physical signs of the disease are more noticeable and may begin to affect your daily life.
Late Intermediate Stage
In the late intermediate stage of HD, the disease's effect on your life becomes more pronounced. Sometimes referred to as stage III, many people at this stage of the disease can no longer work and struggle to complete basic daily tasks. 8
Early Advanced Stage
The early advanced stage of HD usually begins about a decade after the onset of the disease but can range from nine to 21 years after symptoms start. 8
Advanced Stage
At the most advanced stage of HD (stage V), many people with the disease require around-the-clock skilled nursing care. Their movement is severely limited, and it can be difficult to complete any basic motor function.

Huntington's disease is a neurodegenerative disease that causes emotional, behavioral, cognitive, and physical problems.

Home Remedies and Lifestyle
- A preliminary diagnosis of Huntington's disease is based primarily on your answers to questions, a general physical exam, a review of your family medical history, and neurological and psychiatric examinations.
Prescriptions
- Managing Huntington's disease affects the person with the disorder, family members and other in-home caregivers. As the disease progresses, the person will become more dependent on caregivers. Several issues will need to be addressed, and the ways to cope with them will change over time.
Surgeries and Specialist-Driven Procedures
- A number of strategies may help people with Huntington's disease and their families cope with the challenges of the disease.
Emerging Treatment
- If you have any signs or symptoms associated with Huntington's disease, you'll likely be referred to a neurologist after an initial visit to your provider. A review of your symptoms, mental state, medical history and family medical history can all be important in the clinical assessment of a potential neurological disorder.
