Deep brain stimulation targeting the Globus pallidus internus for Parkinson's disease and Tourette syndrome.

We present a case with co-existing Parkinson's disease and Tourette syndrome. Patient takes aripiprazole for Tourette syndrome, which unfortunately worsens his parkinsonian symptoms. We placed deep brain stimulation targeting the Globus pallidus internus. Strikingly, his parkinsonian motor symptoms and his tics are both well controlled with deep brain stimulation.
