Generalized dystonia occurs frequently in children and adolescents; however, presentation with predominant camptocormia is rare and poses significant diagnostic as well as therapeutic challenges (1,2) . The diagnostic distinction between acquired, potentially treatable causes and genetic or idiopathic etiologies can be difficult, often delaying appropriate intervention (3) . We present the case of an adolescent girl with progressive isolated camptocormia, significant diagnostic ambiguity , and poor response to conventional medical and immunological therapies , who showed significant improvement following deep-brain stimulation (DBS) .
Farsana et al. (Sun,) studied this question.
