Huntington's strengthens the immune system during most fertile years allowing them to produce more offspring. Symptoms associated with Huntington's occur later in life, after peak reproductive age.
Although it may cause disease, the gene has also been shown to be critical for brain development and, within a normal range of repeats, appears to have a beneficial effect on cognitive functioning. In other words, within a specific range, a larger number of repeats is associated with higher IQ in a healthy population.
Huntington's disease is a condition that damages nerve cells in the brain causing them to stop working properly. It's passed on (inherited) from a person's parents. The damage to the brain gets worse over time. It can affect movement, cognition (perception, awareness, thinking, judgement) and mental health.
You could experience psychological distress. Although Huntington's disease itself isn't fatal, the average lifespan for someone who's diagnosed with Huntington's disease is another 10 to 30 years after the condition begins because of complications, like the inability to swallow, move and eventual confinement.
Abstract. Woody Guthrie was an American songwriter, musician, writer, and political activist who died with Huntington disease (HD) in 1967 at age 55. His relatively brief creative life was incredibly productive with countless songs and a tremendous volume of letters to his name.
Mood and behavioral changes
Agitation, irritability, and aggression are other possible personality changes. Some patients may experience hallucinations and delusions that can severely affect their day-to-day interactions. Living with Huntington's can induce feelings of anxiety, depression, apathy, and frustration.
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.”
The survival of Huntington's disease (HD) patients is reported to be 15–20 years. However, most studies on the survival of HD have been conducted in patients without genetic confirmation with the possible inclusion of non-HD patients, and all studies have been conducted in Western countries.
There's currently no cure for Huntington's disease or any way to stop it getting worse. But treatment and support can help reduce some of the problems caused by the condition.

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. The clinical depression associated with Huntington's disease may increase the risk of suicide.
While the cause of the disease is known — a single mutated gene — there is no cure. “Our plan is to conduct human clinical trials that deliver stem cells to replace damaged brain cells, reducing levels of harmful proteins that build up in the brains of Huntington's disease patients.”
Research on the evolutionary genetics of this disease suggests that there are two main reasons for the persistence of Huntington's in human populations: mutation coupled with weak selection.
The disease is genetic, which means it is inherited from your parents. 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.
The youngest symptomatic child documented had an age of onset of 18 months,3 with other children developing symptoms in their teens, meaning that some individuals with JHD may now be in their twenties. HD is a life-limiting condition usually lasting 15–20 years from onset.
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.
Nine patients have died, and seven have been lost to follow up. The range of disease duration was between 2 and 17 years, the oldest living to age 91.
When alcohol becomes a coping mechanism for Huntington's disease, that's when it becomes a problem. “With any neurodegenerative or medical disease, drinking a lot can certainly affect your balance and your gait,” says Dr. Oguh.
Huntington's disease does not skip generations. Each child of a parent with Huntington's has a 50% chance of inheriting the defective gene. If a child does not inherit the gene, he or she cannot pass it on. If the child does inherit the gene, he or she can pass it on and will develop the disease.
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.
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.
Huntington disease affects an estimated 3 to 7 per 100,000 people of European ancestry. The disorder appears to be less common in some other populations, including people of Japanese, Chinese, and African descent.
Huntington's disease impairs the functioning of the brain, which can result in apathy, trouble organizing, impulsivity, irritability and anger, unawareness, disinhibition, preservation, and other psychiatric symptoms. These emotional and behavioral symptoms can further complicate the caregiver's role.
