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.
