[Deep brain stimulation for dystonia. Consensus recommendations of the German Deep Brain Stimulation Association]

Medical treatment of dystonia, particularly generalised forms of the disorder, is often not satisfactory or causes intolerable side effects. In focal dystonia, a reasonable treatment option with botulinum toxin exists but some patients either do not respond well or develop neutralising antibodies with secondary therapy failure. Deep brain stimulation (DBS) of the globus pallidus internus has been shown to be effective in both generalised and focal dystonia. This paper gives recommendations regarding the use of DBS in different forms of dystonia based on the currently available scientific data as well as the longstanding personal experience of the authors. The inclusion criteria for DBS candidates as well as the peri- and postoperative patient management are addressed. These recommendations were developed in a consensus procedure in the German Deep Brain Stimulation Association.
