Summary: observational study to evaluate the long-term motor and non-motor effects of deep brain stimulation (dbs) of the globus pallidus internus (gpi) on medically refractory dystonia.Dystonia is a chronic disease affecting mainly young patients with a regular life expectancy and lifelong need for therapy.Pallidal dbs is an established/ treatment for severe isolated dystonia /ut long-term data are sparse.The authors considered 36 consecutive patients with isolated generalized (n = 14) and cervical/segmental (n = 22) dystonia operated at (b)(6)-university hospital between 2000 and 2007 in a retrospective analysis for long-term outcome of pallidal dbs.In 19 of these patients, we could analyze dystonic symptoms and disability rated by the burke¿fahn¿marsden dystonia rating scale (bfmdrs) at baseline, short-term (st-fu, range 3¿36 months) and long-term follow-up (lt-fu, range 93¿197 months).Quality of life and mood were evaluated using the sf36 and beck depression index (bdi) questionnaires.Patients reached an improvement in motor symptoms of 63.8 ± 5.7% (mean ± se) at st-fu and 67.9 ± 6.1% at lt-fu.Moreover, a significant and stable reduction in disability was shown following dbs (54.2 ± 9.4% at st-fu and 53.8 ± 9.2% at lt-fu).Bdi and sf36 had improved by 40% and 23%, respectively, at lt-fu (n = 14).Stimulation-induced adverse events included swallowing difficulties, dysarthria, and bradykinesia.Pulse generator (n = 3) and electrodes (n = 5) were revised in seven patients due to infection.Pallidal dbs is a safe and efficacious long-term treatment for dystonia with reported events: 1.One patient implanted with bilateral internal globus pallidus (gpi) deep brain stimulation (dbs) for dystonia committed suicide 2 years after bilateral pallidal stimulation.2.One patient implanted with bilateral gpi-dbs for dystonia died in consequence of intracerebral bleeding following lysis therapy due to post-operative systemic pulmonary embolism two days after bilateral pallidal lead re-implantation.The following device information was identified in the literature article: ins models 37612, 37601, 7428 and lead models 3387 and 3389.
