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.
HD is caused by a mutation in the gene for a protein called huntingtin. The defect causes the building blocks of DNA called cytosine, adenine, and guanine (CAG) to repeat many more times than they normally do. Most people have fewer than 27 CAG repeats in their HD gene, so they are not at risk for the disease.
An affected person usually inherits the altered gene from one affected parent. In rare cases, an individual with Huntington disease does not have a parent with the disorder. As the altered HTT gene is passed from one generation to the next, the size of the CAG trinucleotide repeat often increases in size.
The future of Huntington's disease management
“The goal is to slow down the course of Huntington's disease, preferably preventing its progression entirely.” Younes indicated there might even be an opportunity to proactively start treatment for people who carry the genetic mutation that causes Huntington's disease.
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.
Huntington's disease is a serious and rare genetic brain disease. There's currently no cure, but an experimental drug is showing promising results and giving those living with the disease, and their families, hope.
It affects males and females equally and crosses all ethnic and racial boundaries. Typically, symptoms begin between age 30 and 55. Children of parents with Huntington's disease have a 50 percent chance of inheriting the HD gene.
The range of disease duration was between 2 and 17 years, the oldest living to age 91.
You're usually only at risk of developing it if one of your parents has or had it. Both men and women can get it. If a parent has the Huntington's disease gene, there's a: 1 in 2 (50%) chance of each of their children developing the condition – affected children are also able to pass the gene to any children they have.
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.
Because Huntington's is a genetic disease, you can't do anything to prevent it if you have inherited it. If you have a history of Huntington's disease in your family, you may wish to have genetic counseling before having children of your own.
The journal Nature Medicine has identified a phase 3 study of pridopidine as a treatment for Huntington's disease as one of 11 clinical trials that will shape medicine in 2022.
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.
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.
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.
With dominant diseases like Huntington's Disease (HD), it is usually pretty easy to figure out risks. Generally if one parent has it then each child has a 50% chance of having it too. And if neither parent has the disease, then odds are that none of the kids will either. Huntington's is a dominant genetic 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.
Conclusion The most primary cause of death in HD is aspiration pneumonia.
At this stage, a person with Huntington's is no longer able to do their own personal care and domestic responsibilities, and will have difficulty with mobility, needing to be in a chair or bed most of the time. Swallowing may be difficult and there may be significant weight loss.
Foods to avoid for Huntington's disease
These foods include: Raw fruits. Stringy vegetables. Tough, crusty breads.
