TMS Therapy for Depression

Transcranial Magnetic Stimulation (TMS) is an FDA-cleared, non-invasive treatment for major depression. It uses focused magnetic pulses — similar in strength to an MRI — to stimulate the dorsolateral prefrontal cortex, the area of the brain involved in mood regulation that often shows reduced activity in depression.

Key points patients ask about up front:

• Non-invasive. No surgery, no anesthesia, no sedation.
• Drug-free. TMS works without medication, so there are no systemic side effects like weight gain, sexual dysfunction, or sedation.
• You stay awake. You sit in a chair, the device is positioned against your scalp, and you can read, talk, or watch something during the session.
• You drive yourself home. No downtime, no recovery period.

TMS is FDA-cleared for major depressive disorder, with additional clearances for OCD and certain anxiety presentations. We focus on its use for treatment-resistant depression — patients who haven't gotten enough relief from antidepressants alone.

TMS is most often used for adults with treatment-resistant depression — major depressive disorder that hasn't responded to one or more well-dosed antidepressant trials. Typical TMS candidates include patients who:

• Have tried two or more antidepressants without adequate relief
• Couldn't tolerate antidepressant side effects
• Want a drug-free option that doesn't interact with their other medications
• Are managing depression alongside chronic medical conditions where adding another systemic medication isn't ideal

TMS is not typically used as a first-line treatment. Most patients arrive at TMS after working through standard depression treatment first. It's also generally not appropriate for patients with implanted metal in or near the head (cochlear implants, deep brain stimulators, aneurysm clips) or those with a personal history of seizures or seizure-risk conditions — we screen carefully during evaluation. The National Institute of Mental Health TMS resource is a useful background reference.

A typical TMS course runs about 36 sessions over 6 weeks. Here's the structure:

1. Consultation and candidacy review — we confirm the depression diagnosis, review your medication history, screen for contraindications, and pull together documentation for insurance authorization.
2. Mapping session — the first session is longer because we map the exact location and intensity (motor threshold) for your treatment.
3. Daily sessions — typically 5 days a week for 6 weeks. Each session is about 20 minutes once the device is positioned. You stay awake, can drive yourself home, and return to work the same day.
4. Sensation during treatment — a tapping or clicking sensation at the treatment site. Most patients adjust within the first few sessions. Mild scalp discomfort or headache is common and usually fades.
5. Tapering and maintenance — sessions often taper at the end of the course. Some patients benefit from periodic maintenance sessions; we'll discuss what fits you.

Response usually shows up in the second half of the course. Some patients notice changes in the first 2 weeks; others don't see meaningful change until week 4 or 5.

Insurance coverage for TMS has improved dramatically over the last decade. Medicare covers TMS for major depressive disorder when criteria are met. Most major commercial insurance plans cover TMS after documented trials of one to four antidepressants, depending on the plan. Prior authorization is required for virtually every insurer. We handle the paperwork — medication history documentation, prior provider records, and clinical justification.

If TMS isn't right for you — or you've completed a TMS course and need another option — we also discuss ketamine therapy, which works through a different mechanism and is appropriate for many of the same treatment-resistant patients. For full background on brain stimulation therapies, the American Psychiatric Association's depression treatment guidelines cover where TMS fits in the standard treatment hierarchy.

Talk to us about TMS if any of these are true:

• You've tried two or more antidepressants and still feel depressed
• Antidepressant side effects have made the medications unsustainable
• You want a drug-free option for depression
• You've responded to TMS in the past and need another course
• Your depression is interfering with work, family, or your physical health

If you're in crisis or having thoughts of self-harm, call or text 988 — TMS is not an emergency intervention. We pick up TMS planning as soon as you're stable.

TMS works best when the team handling it knows your full medical picture and stays available throughout the 6-week course.

• 22 years of clinical experience under our practice lead — including emergency department work where treatment-resistant depression presents in its most urgent forms
• Primary care plus mental health under one roof — your thyroid, sleep, and other medical contributors get addressed alongside TMS
• Hands-on insurance authorization — we own the paperwork so you don't have to chase it
• Real continuity — same team coordinating your TMS, your medication management, and your therapy referrals
• Serving the Triangle — Knightdale, Wendell, Zebulon, Rolesville, Wake Forest, Garner, and East Raleigh
