Where is Huntington disease most common?
For example, the Lake Maracaibo region of Venezuela is believed to have the highest prevalence of HD in the world with about 700 per 100,000 affected. The condition occurs less frequently in Japan, China, and Finland, as well as among black people of African descent.
How common is Huntington’s disease in the world?
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.
How much of the world has Huntington’s disease?
The worldwide service-based prevalence of HD, based on a meta-analysis (n = 13 studies), was 2.71 per 100,000 (95% CI: 1.55-4.72). Eleven studies were conducted in Europe, North American, and Australia, with an overall prevalence of 5.70 per 100,000 (95% CI: 4.42-7.35).
Why is Huntington’s disease not more prevalent in the population?
Huntington’s is often “invisible” to natural selection for a very simple reason: it generally does not affect people until after they’ve reproduced. In this way, the alleles for late-onset Huntington’s may evade natural selection, “sneaking” into the next generation, despite its deleterious effects.
Who is most at risk for Huntington’s disease?
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.
How old is the oldest person with Huntington’s disease?
The range of disease duration was between 2 and 17 years, the oldest living to age 91. The 34 cases were from thirty-one different pedigrees. Eleven of the cases had a family history of HD, with average age of onset in the family being 60 years.
How is Huntington’s disease prevalent in the population?
Incidence and Prevalence of Huntington’s Disease. Experts estimate that one in every 10,000 persons-nearly 30,000 in the United States-have Huntington’s disease. Juvenile Huntington’s occurs in approximately 16 percent of all cases. Huntington’s disease is not prevalent within any particular population.

How serious is Huntington’s disease?
Huntington’s disease is an incurable, hereditary brain disorder. It is a devastating disease that causes damage to brain cells, or neurons. It happens when a faulty gene causes toxic proteins to collect in the brain. Huntington’s disease (HD) affects one person in every 10,000,…
What are the long term effects of Huntington’s disease?
They tend to worsen over 10 to 20 years . Eventually the Huntington’s disease or its complications are fatal. According to the Huntington’s Disease Society of America (HDSA), the symptoms of HD can feel like having amyotrophic lateral sclerosis (ALS), Parkinson’s and Alzheimer’s all in one.
