The median timeframe of survival for someone with adult-onset Huntington's (or Huntington) disease (HD) is 15-18 years after symptoms begin. The average age of death for a person with HD is 54-55 years of age. Some individuals live longer, especially if symptoms do not begin until a later age. Juvenile HD, which is rarer than adult-onset HD, has a rapid disease progression once symptoms begin. Death typically occurs in people with JHD within 10 years of the start of symptoms. People with the adult-onset form of Huntington disease typically have 40 to 50 CAG repeats in the HTT gene, while people with the juvenile form of the disorder tend to have more than 60 CAG repeats. Huntington disease is a progressive brain disorder that causes uncontrolled movements, emotional problems, and loss of thinking ability (cognition). Adult-onset Huntington disease, the most common form of this disorder, usually appears in a person's thirties or forties. Early signs and symptoms can include irritability, depression, small involuntary movements, poor coordination, and trouble learning new information or making decisions.

Clinical characteristics of childhood-onset (juvenile) Huntington disease: report of 12 patients and review of the literature. The HTT mutation that causes Huntington disease involves a DNA segment known as a CAG trinucleotide repeat. This segment is made up of a series of three DNA building blocks (cytosine, adenine, and guanine) that appear multiple times in a row. Normally, the CAG segment is repeated 10 to 35 times within the gene. In people with Huntington disease, the CAG segment is repeated 36 to more than 120 times. People with 36 to 39 CAG repeats may or may not develop the signs and symptoms of Huntington disease, while people with 40 or more repeats almost always develop the disorder. Sources^. 1  1.

Stages-of-HD People with Huntington’s disease (HD) follow a path of disease progression once symptoms begin. While patients can remain highly functional in the first years of the disease, independence gives way as symptoms get worse. This article discusses the ways in which HD symptoms change from one stage to the next, the degree to which […] A group of scientists in the European Huntington’s Disease Network wanted to understand what people with HD were most concerned about on a day-to-day basis, and interviewed 31 people in all stages of HD.
