STN DBS may result in either a favorable or an unfavorable outcome in patients with Parkinson disease and impulse control and related disorders. [93] Although there may be resolution or improvement of impulse control disorders following STN DBS, the procedure may also induce, exacerbate, reveal, or have no effect on these conditions. [93]

In 2017, the FDA approved the Vercise DBS system to treat symptoms of Parkinson disease. The device is a rechargeable implantable pulse generator with a potential battery life of 15 years. It has been available in Europe since 2012. [94]
