IMAGES: Polysomnographic artifact in a patient with Tourette syndrome

Patients with Tourette syndrome frequently have sleep disturbances that may require polysomnographic testing. The use of deep brain stimulators is increasing with expanding indications including children with medically intractable Tourette syndrome. It is important to understand the effect the stimulator can have on polysomnographic monitoring. Herein we present an interesting case of an adolescent with medically intractable Tourette syndrome with a deep brain stimulator implant who underwent a polysomnogram demonstrating rhythmic, monomorphic artifact.
