NeuroStar is an FDA-cleared transcranial magnetic stimulation (TMS) system that treats depression by delivering targeted magnetic pulses to the brain. It’s specifically designed for people whose depression hasn’t improved with antidepressant medication. The device is also cleared for obsessive-compulsive disorder (OCD) and depression accompanied by significant anxiety.
How NeuroStar Works
During a session, a curved device called a coil is placed against your scalp near your forehead. The coil generates brief magnetic pulses, similar in strength to an MRI, that pass through the skull and stimulate nerve cells in the area of the brain that regulates mood. In people with depression, this region tends to be underactive. Repeated stimulation over several weeks helps restore more normal activity patterns.
The treatment is noninvasive. There’s no anesthesia, no sedation, and no recovery time. You sit in a chair, stay fully awake, and can drive yourself home afterward.
What a Treatment Course Looks Like
A standard NeuroStar course runs about 36 sessions over six to seven weeks. Sessions are typically scheduled five days a week, Monday through Friday. Each session lasts roughly 19 minutes with NeuroStar’s shorter “Dash” protocol, which has largely replaced the older 38-minute version.
During your first visit, the provider maps your scalp to find the precise treatment location and calibrates the pulse intensity to your individual threshold. Most people describe the sensation as a tapping or tingling feeling on the scalp. This can be uncomfortable during the first few sessions but generally fades by the second week. You can go back to work or your normal routine immediately after each session.
Who Qualifies for Treatment
NeuroStar is FDA-cleared for adults with major depressive disorder who haven’t responded to prior antidepressant medication. A newer clearance also covers adolescents ages 15 to 21. For insurance purposes, most plans require that you’ve tried and not improved with at least two antidepressant medications, though some insurers set the bar at up to four failed medications. You’ll need documentation showing those treatments were given adequate time to work.
Coverage for OCD follows a similar pattern: a diagnosis plus evidence that at least two medications and psychotherapy haven’t provided sufficient relief. Pregnancy or nursing typically disqualifies you from coverage.
Who Should Not Use It
NeuroStar cannot be used if you have magnetic-sensitive metal implanted in or near your head. This includes cochlear implants, aneurysm clips or coils, metal stents, implanted electrodes or stimulators, and bullet fragments. The magnetic pulses could move or heat these objects. Standard dental fillings and braces are generally fine since they aren’t ferromagnetic.
People with a history of seizures or a family history of epilepsy need extra caution. While the seizure risk with TMS is very low (less than 0.1% of patients), it does exist, and your provider will weigh this carefully before starting treatment.
How Effective It Is
A large real-world study published in Brain Stimulation tracked over 2,100 patients treated with NeuroStar across both protocols. Response rates, meaning at least a 50% reduction in depression symptoms, ranged from 58% to 72% depending on how strictly adherence was measured. Remission rates, meaning symptoms dropped to minimal levels, fell between 28% and 53%. Those numbers are notable because these patients had already failed to improve on antidepressant medication.
Separate clinical trial data puts the numbers even higher for patients who complete the full course: 83% experiencing measurable improvement and 62% reaching full remission. The gap between these figures and the real-world study likely reflects the difference between tightly controlled trials and everyday clinical practice, where some patients miss sessions or drop out early. Completing all 36 sessions matters significantly for outcomes.
Side Effects
The most common side effect is discomfort at the treatment site, a tapping or stinging sensation under the coil. For most people, this fades within the first week of treatment and doesn’t require stopping the course. Headaches can occur after sessions, particularly early on, and typically respond to over-the-counter pain relievers.
Unlike antidepressant medications, NeuroStar does not cause weight gain, sexual dysfunction, drowsiness, or the emotional blunting that many patients find intolerable with pills. Unlike electroconvulsive therapy (ECT), it carries no risk of memory loss and requires no anesthesia. The seizure risk, while real, is extremely rare at less than 0.1%.
How It Compares to ECT
ECT remains one of the most effective treatments for severe depression, and it works faster than TMS. But the tradeoffs are significant. ECT requires general anesthesia and muscle relaxants, meaning someone needs to drive you home and you’ll lose part of your day to recovery. Side effects include nausea, confusion, fatigue, and memory loss. While memory typically improves within a few months, some people develop permanent gaps, particularly around events close to the treatment dates. ECT can also cause temporary spikes in heart rate and blood pressure.
NeuroStar’s milder side effect profile makes it a better fit for people whose depression is treatment-resistant but not at the severity level where ECT’s faster action is critical. Many providers position TMS as the next step after medication fails and before considering ECT.
Insurance and Cost
Most major insurance plans now cover NeuroStar for depression, though the approval process requires documentation. You’ll need a formal diagnosis of moderate to severe major depressive disorder and records showing that previous medications were tried at adequate doses for sufficient time. Keeping detailed treatment records, including start dates, dosages, and why each medication was discontinued, makes the authorization process smoother.
Out-of-pocket costs without insurance vary widely by provider and region, but a full 36-session course can run anywhere from several thousand to over ten thousand dollars. Many NeuroStar providers offer payment plans or can help navigate the prior authorization process with your insurer.
