Huntington’s disease is an autosomal dominant genetic disorder characterized by progressive dementia and dance. Age varies greatly, usually occurs in 21 to 50 years (mean 41 years), the average age of death was 54 years. The performance of Huntington’s disease is influenced by the gender of the patient in the parent. The onset of the disease before the age of 21 is dominated by the father, while in the late-onset patients, the majority are inherited by the mother. Early cases of ankylosis, it was reported 70 cases of tetanus Huntinton’s disease, the average age of onset was 22.2 years old. Juvenile patients, the age of onset of 4 to 10 years old (2% of the total), clinically characterized by rigidity, decreased exercise, epilepsy and mental decline, the disease course than the incidence of middle age. Youth type (10 to 20 years of age, accounting for 4%) is relatively close to middle-aged. 50-year-old onset of late-onset type. The authors analyzed 25 cases of late-onset cases with an average age of onset of 57.5 years. There were 12 males and 13 females, with an average of 63.1 years of age at the time of diagnosis. 25 cases showed performance of dance, muscle tension and low
