OBJECTIVES: To describe the clinical and epidemiologic aspects of different @entity3520 . @entity1 AND METHODS: A total of 205 @entity1 with primary @entity3520 were studied retrospectively and the following variables were analyzed: gender, age of onset, age at examination, evolution time, history of @entity130 , association with other @entity717 , @entity3520 as well as a family history of @entity3519 , @entity191 , @entity400 , and lefthandedness or stuttering. We compared these variables among the different clinical categories of @entity3520 . RESULTS: Those @entity1 with @entity3519 were significantly older at the onset of symptoms compared with @entity1 with @entity3520 . Males were more prevalent than females in all categories of @entity3520 except for @entity3519 . Prior history of @entity130 and association with @entity400 were more frequent in @entity1 with cervical @entity3519 than in those with others dystonic categories. Most @entity1 with @entity6389 had fluctuations in the intensity of @entity3520 , unlike the @entity1 with @entity3520 . CONCLUSIONS: There is a caudo-cranial gradient in age of onset and the age of onset increases as the cranial presentation becomes greater. Females are more prevalent in @entity3519 and there is a preponderance of @entity3519 with a lower location. The @entity3519 with cranial distribution frequently present fluctuations of symptoms during the day. Association with other @entity717 , such as @entity400 , and prior history of @entity130 , is common in @entity1 with cervical @entity3519 .
