A Huntington disease-like syndrome is a disorder that looks similar to Huntington disease, as its name suggests. HDL syndromes occur in people with Huntington disease who do not have a mutation in HD, the gene normally associated with the condition. Many people are affected by compulsory jerking or twitching movements known as chorea. People with these disorders also experience personality shifts, as well as a decline in reasoning and reasoning skills. Individuals with an HDL syndrome can live for a few years to more than a decade after signs and symptoms appear. HDL3 appears much earlier in life than many of the other HDL syndromes. Since HDL3 has a slightly different pattern of signs and symptoms and a distinct pattern of inheritance, researchers are uncertain if it belongs to the same group as the other HDL syndromes.
Huntington disease is a progressive brain disorder that causes uncontrolled movements, emotional disorders, and loss of thinking skills. Many people with Huntington disease have involuntary jerking or twitching movements called chorea. Affected individuals can have a difficult time walking, speaking, or swallowing. Changes in personality and a decrease in reasoning and reasoning skills are common among people with this disorder. Individuals with Huntington disease with adult-onset Huntington disease usually live for about 15 to 20 years after signs and symptoms develop. The juvenile disease, which is less common in childhood or adolescence, appears in childhood or adolescence. As reasoning and reasoning skills become more restricted, school achievement is dwindling. Seizures account for 30 percent to 50% of children with this disease. Juvenile Huntington disease is a chronic disease that causes the development of adult-onset; affected individuals typically live 10 to 15 years after signs and symptoms appear.
