Skoch","Scott J. Sherman"],"abstract":"Background: The long-term safety of deep brain stimulation (DBS) is an important issue because new applications are being investigated for a variety of disorders. Studying instances where DBS was inadvertently implanted in patients without a movement disorder may provide information about the safety of the therapy. We report the case of a patient with a psychogenic movement disorder treated with deep brain stimulation (DBS). Case Description: The patient presented at our clinic after 5 years of chronic DBS of the subthalamic nucleus (STN) for presumed Parkinson's disease. A dopamine transporter (DAT) scan (DaTscan) showed normal DAT distribution in the striatum. A positron emission tomography (PET) scan showed no abnormal metabolic patterns. Further psychiatric and neurological evaluations revealed that the patient was suffering from a psychogenic movement disorder. The patient displayed no sign or symptom from the stimulation, and DBS did not lead to any benefits or side effects for this patient. Conclusion: We argue that the absence of side effects, the normal DaTscan, and PET scan after 5 years of chronic stimulation illustrate the safety of DBS on neural tissue.","thumbnailUrl":"https://sni-digital-videos.s3.amazonaws.com/articles/67660a92-444f-4057-aa49-1cb1bbbb5835/featured/hero-1782420863435.png","publishDate":"2016-11-14T00:00:00.000Z","doi":"10.4103/2152-7806.194063","categories":["Stereotactic","Case Report"],"fullTextUrl":"http://surgicalneurologyint.com/wp-content/uploads/2016/11/8140/SNI-7-824.pdf"}
