Treatment for dystonia in childhood.

Management of childhood dystonia differs in certain respects from that of adult dystonia: (i) childhood dystonia is more often secondary than primary; (ii) mixed motor disorders are frequent; (iii) in children, the course of dystonia may be influenced by ongoing brain maturation and by the remarkable plasticity of the young brain; (iv) drug tolerability and effectiveness can be different in children; (v) the therapeutic strategy must be discussed with both the patient and his or her parents; and (vi) the child's education must be taken into account. Based on a systematic review of the literature through June 2011 and on our personal experience, we propose a therapeutic approach to childhood dystonia. After a detailed clinical evaluation and a comprehensive work-up to rule out a treatable cause of dystonia, symptomatic treatment may include various drugs, local botulinum toxin injections, and deep brain stimulation, in addition to rehabilitation.
