Depression

We write about a novel idea to address brain-based disorders that has moved from theory to bedside in only 3 years. Called closed-loop neuromodulation, it involves using electrical stimulation—delivered via an implanted deep-brain stimulation (DBS) device—at a precise location in the brain. The stimulation occurs intermittently throughout each day for only seconds at a time, and only at moments when a sensor placed in another part of the brain detects a specific EEG brain-wave pattern linked with the onset of a patient’s depressed moods.  In its first clinical test, a treatment-resistant patient experienced a remission.
