Here is an Example of DBS ( Deep Brain Stimulator ) Artifact in an EEG recording

DBS Artifact in EEG 001

This makes it almost necessary to turn off the DBS Stimulator before conducting an accurate EEG. My times have I experienced patients come for an EEG ordered by a Neurologist without being presented with any concept to turn this devise off for the EEG exam.

Deep brain stimulation (DBS) is a neurosurgical procedure involving the implantation of a medical device called a brain pacemaker, which sends electrical impulses, through implanted electrodes, to specific parts of the brain (brain nucleus) for the treatment of movement and affective disorders. DBS in select brain regions has provided therapeutic benefits for otherwise-treatment-resistant movement and affective disorders such as Parkinson's disease, essential tremor, dystonia, chronic pain, major depression and obsessive–compulsive disorder (OCD).[1] Despite the long history of DBS,[2] its underlying principles and mechanisms are still not clear.[3][4] DBS directly changes brain activity in a controlled manner, its effects are reversible (unlike those of lesioning techniques), and it is one of only a few neurosurgical methods that allow blinded studies.[citation needed]
Food and Drug Administration (FDA) approved DBS as a treatment for essential tremor in 1997,[citation needed] for Parkinson's disease in 2002,[5] dystonia in 2003,[6] and OCD in 2009.[7] DBS is also used in research studies to treat chronic pain and has been used to treat various affective disorders, including major depression; neither of these applications of DBS have yet been FDA-approved. While DBS has proven helpful for some patients, there is potential for serious complications and side effects.
