New targeting method may allow tremor surgery without being awake

This study tested a new way to guide deep brain stimulation (DBS) surgery for essential tremor. Normally, patients must be awake during surgery to help doctors find the right spot in the brain. The new method uses a computer model to target the area while the patient is asleep. The study included 22 adults with severe tremor and aimed to see if the asleep procedure works as well as the standard awake approach.
