Electrical stimulation of the brain using a pacemaker -like device was introduced several years ago to help control seizures in patients with epilepsy and help Parkinson's disease patients better control their movements. But this is the first time so-called deep- brain stimulation has been used to treat major depression.
Can a pacemaker for the brain help depression?
[Photo: Maurice Ramirez/UCSF] UCSF Health physicians have successfully treated a patient with severe depression by tapping into the specific brain circuit involved in depressive brain patterns and resetting them using the equivalent of a pacemaker for the brain.
What is a pacemaker-like device?
A pacemaker -like device, implanted in the body, is attached to a stimulating wire that is threaded along a nerve called the vagus nerve. The vagus nerve travels up the neck to the brain, where it connects to areas believed to be involved in regulating mood. Once implanted, this device delivers regular electrical impulses to the vagus nerve.
Can a pacemaker be used to treat bradycardia?
Conditions Treated with a Pacemaker. Our electrophysiologists are experienced in using pacemakers to treat bradycardia. Your heart normally beats at a rate of 60 to 100 times a minute. If you have bradycardia, your heart is beating at a rate slower than 60 times a minute.
How can precision medicine help with depression?
“We’ve developed a precision-medicine approach that has successfully managed our patient’s treatment-resistant depression by identifying and modulating the circuit in her brain that’s uniquely associated with her symptoms.”

How do you think the pacemaker-like device works to combat depression?
The electrodes are connected via wires to a pacemaker-like device implanted in the chest that delivers pulses of electricity to the brain. The pulses, which are generally delivered constantly appear to block the firing of neurons and return the brain's metabolism back to a state of equilibrium.
What is the depression treatment device?
Transcranial magnetic stimulation (TMS) is a noninvasive procedure that uses magnetic fields to stimulate nerve cells in the brain to improve symptoms of depression. TMS is typically used when other depression treatments haven't been effective.
What is VNS treatment for depression?
Vagus nerve stimulation (VNS) is a surgical procedure that can be used to treat those with treatment-resistant depression. A pacemaker-like device, implanted in the body, is attached to a stimulating wire that is threaded along a nerve called the vagus nerve.

How do DBS treat severe depression?
Deep brain stimulation works like a pacemaker, but it's used in the brain instead of in the heart. This technique requires surgically placing a small conductor, called an electrode, permanently in the brain. The electrode delivers a low level impulse that aids in regulating mood.
How effective is VNS for depression?
VNS was well tolerated over the longer term, and 81 percent of the group originally implanted still had the device active at the two-year mark. The overall response rate of 40 to 45 percent long term (<50% reduction in depressive symptoms) contrasts with the 81 percent who still have the device active at two years.
Why is ECT used for depression?
With ECT, an electrical stimulation is delivered to the brain and causes a seizure. For reasons that doctors don't completely understand, this seizure helps relieve the symptoms of depression. ECT does not cause any structural damage to the brain.
How does VNS therapy work?
Vagus nerve stimulation (VNS) sends regular, mild pulses of electrical energy to the brain via the vagus nerve, through a device that is similar to a pacemaker. There is no physical involvement of the brain in this surgery and patients cannot generally feel the pulses.
What is the most effective treatment for depressed patients?
Medications and psychotherapy are effective for most people with depression. Your primary care doctor or psychiatrist can prescribe medications to relieve symptoms. However, many people with depression also benefit from seeing a psychiatrist, psychologist or other mental health professional.
