When the pacemaker-like brain implants do help depressed people, they get dramatically better. “I have patients who got their implants 10 years ago now,” says Helen Mayberg , a professor of psychiatry and neurology at Emory University and a leading researcher on DBS for depression. “These people get well and they stay well,” she says. 2. Unfortunately, they don’t help everybody. Experimental trials by Mayberg and others have consistently had a subset of people who simply don’t respond to the treatment.
