TMS Therapy for Depression
Tired of trying pills that fail, fade, or leave you with flat emotions? TMS therapy for depression works differently—no medication or systemic side effects, just focused magnetic pulses targeting the mood-regulating brain circuits you need.

Symptoms of Major Depressive Disorder
Depression isn’t just sadness. It changes how you sleep, eat, move, think, and feel. The table below shows how MDD shows up in daily life.
Symptom Domain
Depressed mood
Loss of interest (anhedonia)
Sleep disturbance
Fatigue
Appetite change
Concentration difficulty
Worthlessness or guilt
Suicidal thoughts
Common Impact on Daily Life
Persistent emptiness, hopelessness, or irritability most of the day, nearly every day
No pleasure in hobbies, socializing, sex, or activities that used to feel good
Insomnia (trouble falling or staying asleep) or hypersomnia (sleeping 10+ hours and still exhausted)
Profound low energy that makes simple tasks, showering, cooking, and returning emails feel overwhelming
Significant weight loss or gain (5% or more of body weight in a month) without dieting
Brain fog, forgetfulness, inability to read more than a few paragraphs or follow conversations
Harsh self-criticism, feeling like a burden, ruminating on past mistakes
Thinking about death, wanting to go to sleep and not wake up, or active planning for suicide
When five or more of these symptoms persist for at least two weeks, and one of them is depressed mood or loss of interest, the clinical diagnosis is major depressive disorder.
How TMS Works for Depression
Standard antidepressants change brain chemistry everywhere. Serotonin reuptake inhibition happens in your prefrontal cortex. It also happens in your gut, your spinal cord, and your reproductive system. That’s why side effects are systemic.
Here’s what actually happens.
A magnetic coil sits against your scalp, positioned over the left dorsolateral prefrontal cortex (L-DLPFC). That’s the front part of your brain, just behind your forehead. In many people with depression, this region runs underactive. Too quiet. Not enough signaling to the rest of the mood network.
The coil delivers focused magnetic pulses about the same strength as an MRI. Those pulses induce tiny electrical currents in the neurons of the L-DLPFC. Not enough to hurt. Enough to make those neurons fire. That’s the precision behind NeuroStar TMS Therapy.
Repeated stimulation does one main thing: It strengthens synaptic connections through neuroplasticity. The brain learns to keep those mood circuits active even between sessions. Wake up the underactive region enough times, and it starts to stay awake on its own.
The left DLPFC is the target because the evidence is strongest there: High-frequency stimulation to this region has been tested in dozens of clinical trials. It works. That’s why the FDA cleared it.
No sedation. No anesthesia. Nothing circulates in your bloodstream. You drive yourself home afterward.
NeuroStar TMS Treatment For Depression Timeline
A full course of NeuroStar TMS treatment for depression requires commitment. Five days per week for approximately seven weeks. That’s 36 sessions total. Each session runs between 19 and 37 minutes, depending on your personalized protocol.
Free 15-minute consultation
No cost. No obligation. A phone callback to discuss your depression symptoms, what medications you’ve tried, and whether TMS makes sense. Call (617) 958-6036.
Psychiatric evaluation
One of Onward Psychiatry’s board-certified Psychiatric Nurse Practitioners (Hannah Lynch, Kristin Feeley, Carly Munzer, Rebeca Gallego, or Sarah Silva) assesses your full clinical picture. They confirm MDD diagnosis, document treatment resistance, and rule out contraindications.
Genetic testing (optional)
Onward Psychiatry offers pharmacogenomic analysis to understand how your body processes medications. This can help guide future medication choices if needed.
Motor threshold mapping
The clinician finds the exact spot on your scalp that controls thumb movement. That establishes your personal stimulation intensity. Then they map the left DLPFC target position. The first appointment runs about 1.5 hours.
Daily treatment sessions
You recline in a comfortable chair. The coil touches your scalp. Pulses start. You feel a tapping or knocking sensation. You hear clicking sounds. You wear earplugs. You stay completely awake. Most patients read, scroll their phone, or listen to music. When the session ends, you get up and leave.
Immediate return to normal life
No sedation. No recovery room. No driving restrictions. You can go straight back to work, pick up your kids, or run errands.
The “not instant” reality – Most people don’t feel better after one session. Or five. Improvement typically builds over weeks. Some patients notice better sleep or slightly more energy by week 2 or 3. Others take the full 36 sessions before seeing meaningful change.
The TMS dip – Some patients feel worse around week 3 or 4. Temporary. Transient. It passes. Clinicians call it the “TMS dip.” Knowing it exists makes it easier to push through.
Maintenance sessions – After the initial 36 sessions, some patients need follow-up treatments. Weekly or monthly. Tapered gradually. Onward Psychiatry discusses maintenance planning before you finish the acute course.

Frequently Asked Questions
How long does a full course of TMS take?
Approximately seven weeks. Five sessions per week (Monday–Friday). That’s 36 sessions total. Each session lasts 19–37 minutes. Some patients need maintenance sessions afterward—weekly or monthly—to sustain the benefit.
Does TMS work for severe depression?
Yes. The clinical trials and real-world data include patients with moderate to severe MDD. TMS is specifically indicated for treatment-resistant depression, which by definition is severe enough not to have responded to medications.
Does TMS work for bipolar depression?
TMS is FDA-cleared for major depressive disorder (unipolar depression), not bipolar depression. Some research supports TMS for bipolar depression, but it requires careful management to avoid triggering mania. Onward Psychiatry can evaluate whether TMS is appropriate for your specific situation.
What happens if TMS doesn't work for me?
About 40–50% of treatment-resistant patients don’t achieve a 50% symptom reduction. That doesn’t mean you’re out of options. Onward Psychiatry also offers medication management, genetic testing to guide medication choices, and psychotherapy. Your provider will discuss next steps.
Does TMS cause memory loss?
No. That’s one of the main differences between TMS and ECT. TMS does not affect memory or cognitive function. Patients remain fully alert during sessions and report no cognitive side effects.
Can I do TMS if I'm pregnant?
TMS has been studied in pregnant women with depression, and the data suggest it’s safe. However, each case requires careful evaluation. The magnetic field is focused on the scalp and does not penetrate to the abdomen. Discuss pregnancy plans with your provider before starting.
Do you offer TMS for adolescents?
Yes. NeuroStar TMS is FDA-cleared for adolescents aged 15–21 with treatment-resistant depression. Onward Psychiatry can evaluate teens on a case-by-case basis. Parent or guardian consent is required.
Do you offer telehealth?
Yes. Onward Psychiatry offers secure video appointments via Zoom for patients throughout Massachusetts who cannot attend in person. Initial TMS sessions must be in-person, but consultations and follow-up appointments can be done via telehealth.
