HOW TMS
THERAPY WORKS
Transcranial Magnetic Stimulation uses focused magnetic pulses to stimulate underactive brain regions. It's the same magnetic technology as an MRI — but precisely targeted to treat depression, anxiety, PTSD, and OCD.
The Science
How magnetic pulses heal the brain
Your brain communicates through electrical signals between neurons. In conditions like depression, anxiety, and PTSD, certain brain regions become underactive — they're not firing the way they should. This disrupts the neural circuits that regulate your mood, stress response, and emotional processing.
TMS uses a magnetic coil placed against your scalp to deliver brief, focused magnetic pulses. These pulses pass painlessly through the skull and generate small electrical currents in the targeted brain region. This stimulation "wakes up" underactive neurons and promotes the release of neurotransmitters like serotonin, dopamine, and norepinephrine.
Over the course of treatment, repeated TMS sessions create lasting changes in brain connectivity — a process called neuroplasticity. Your brain essentially rewires itself, restoring healthy patterns of activity that persist long after treatment ends.
Magnetic Pulse Delivery
A magnetic coil generates brief pulses (similar to MRI technology) that pass through the skull to reach specific brain regions.
Neural Activation
The pulses stimulate neurons in underactive brain regions, triggering the release of mood-regulating neurotransmitters.
Neuroplasticity
Repeated stimulation strengthens neural connections and creates lasting changes in brain circuitry.
Sustained Recovery
After 36 sessions, the brain maintains its new, healthier patterns of activity — often for 12+ months.
Brain Targets
Different conditions, different brain targets
TMS is not a one-size-fits-all treatment. The magnetic coil is positioned over specific brain regions depending on your condition. This precision is what makes TMS so effective — and so different from medication, which affects the entire brain.
Depression
Left Dorsolateral Prefrontal Cortex (DLPFC)
Stimulating this region increases activity in the brain's mood regulation center, lifting depression and restoring motivation.
Learn moreAnxiety
Right Dorsolateral Prefrontal Cortex (DLPFC)
Calming overactive anxiety circuits by modulating the right prefrontal region, reducing constant worry and physical tension.
Learn morePTSD
Prefrontal Cortex / Amygdala Circuit
Strengthening prefrontal control over the amygdala (fear center), reducing hypervigilance, flashbacks, and emotional reactivity.
Learn moreOCD
Anterior Cingulate Cortex / Medial PFC
Deep TMS (H-coil) reaches deeper brain structures involved in compulsive behavior loops, breaking the cycle of intrusive thoughts.

What happens during a TMS appointment
Check In
You arrive at the clinic and check in. No fasting, no prep, no changing into a gown. Come as you are.
Get Comfortable
You sit in a comfortable reclined chair. The TMS technician positions the magnetic coil against your scalp based on your brain mapping from session one.
Treatment Begins
The device delivers magnetic pulses in short bursts. You'll feel a tapping sensation on your scalp. You're fully awake — you can listen to music, watch a show, or just relax.
Session Complete
The device stops, the coil is removed, and you're done. No recovery time needed. Many patients go straight back to work or school.
Comparison
TMS vs. medication vs. therapy
| TMS | Medication | Talk Therapy | |
|---|---|---|---|
| Systemic Side Effects | None | Common (weight, mood, sleep) | None |
| Time to Effect | 2-4 weeks | 4-8 weeks per trial | Months to years |
| Daily Commitment | None (after 6 weeks) | Daily pill indefinitely | Weekly sessions ongoing |
| FDA Approved | Yes (2008) | Yes | N/A |
| Works With Others | Yes (can combine all 3) | Some interactions | Yes |
| Withdrawal Risk | None | Yes (discontinuation syndrome) | None |
TMS is not a replacement for therapy or medication — it can be used alongside both. Many patients find that TMS makes their therapy more effective and allows them to reduce medication under their doctor's guidance.
FAQ
Common questions about TMS
Does TMS hurt?
Most patients describe TMS as a light tapping or knocking sensation on the scalp. It is not painful for the majority of people. Some patients experience mild scalp discomfort during the first few sessions, which typically resolves as you get used to the sensation. No anesthesia is needed.
Are there side effects from TMS?
TMS has very few side effects compared to medication. The most common is mild scalp discomfort or headache during or after the first few sessions. These typically resolve within the first week. Serious side effects are extremely rare. There is no weight gain, sexual dysfunction, nausea, or drowsiness — common side effects of antidepressants.
Can I drive after a TMS session?
Yes. TMS does not require sedation or anesthesia, and it does not impair your cognitive function. You can drive yourself to and from every appointment and return to work, school, or other activities immediately after each session.
How is TMS different from ECT (electroconvulsive therapy)?
TMS and ECT are very different treatments. ECT requires general anesthesia, induces a seizure, and can cause memory loss. TMS is non-invasive, requires no anesthesia, does not induce seizures, and has no cognitive side effects. You remain fully awake and alert during TMS.
How long do TMS results last?
Many patients maintain significant improvement for 12 months or longer after completing a full TMS course. If symptoms begin to return, maintenance sessions (typically once a month or as needed) can sustain the benefits. Some patients find that a single course of TMS provides lasting relief without additional treatment.
