Abstract

The current available devices for deep brain stimulation (DBS) therapy allow clinicians to use current or voltage between the electrical parameters to improve symptoms. Constant current stimulation may have the putative advantage to avoid the variations in stimulation current delivery that is caused by variations in brain tissue impedance. Although constant current systems might be safer, no strong evidence is available to support this hypothesis or its clinical superiority versus constant voltage (1).
