Frequently Asked Questions
Real answers to the questions we hear most often. If something isn't covered here, a free consultation will get you a straight answer from a provider, not a chatbot...
Logistics and Candidacy
Am I a good candidate for TMS?
Most people who ask this question are better candidates than they think.
TMS is a strong option if you have a diagnosis of depression, OCD, anxiety, or PTSD — particularly if you've tried medication without finding adequate relief, if you've experienced side effects that affect your quality of life, or if you're simply looking for a non-medication path forward. You don't need to have exhausted every other treatment option first. You do need to be medically appropriate for the procedure.
TMS is probably not right for you if: — You have metal implants in or near your head. This includes cochlear implants and certain types of aneurysm clips or deep brain stimulators. Dental fillings, braces, and most orthopedic hardware elsewhere in the body are not a concern. — You have a personal history of seizures or epilepsy. TMS carries a small but real seizure risk, and a seizure history changes that calculation significantly. — You are pregnant. The evidence base here is limited rather than clearly contraindicated — if you're pregnant and interested in TMS, the conversation is worth having with your provider.
If you're unsure whether something in your history disqualifies you, the right answer is a consultation. We'd rather tell you TMS isn't right for you in a free conversation than have you find out after you've committed.

Does Insurance cover TMS?
It depends on which protocol you're considering — and the honest answer is more complicated than most clinic websites let on.
Traditional TMS (6-week): Covered by most major insurance plans, including Medicare and many Medicaid plans, for major depressive disorder. Prior authorization is typically required, and you'll generally need documentation of one or more prior antidepressant trials. Coverage for OCD, anxiety, and PTSD varies significantly by plan.
Accelerated protocols (1-Day and 5-Day Intensive): These are cash-pay. Most insurance plans do not currently cover accelerated TMS, and prior authorization for these protocols is rarely granted through standard channels. We are credentialed with major insurers and can pursue single-case authorization in appropriate circumstances — but we don't want you to plan your finances around that outcome.
The cost comparison worth doing: A "covered" traditional TMS course at a typical $60 specialist copay across 36 visits = $2,160 out of pocket minimum — before your deductible, coinsurance, or any prior authorization delays. Many patients find the true cost of their "covered" option is higher than they expected, and the total cost of our cash-pay accelerated options compares more favorably than it first appears.
We offer in-house payment plans on all cash-pay protocols. If cost is a concern, let's talk about it directly — there may be more options than you think.

What does a TMS session actually feel like?
The most common description is a rhythmic tapping or knocking sensation on the scalp — like someone firmly tapping with two fingers in a fast, regular pattern. Some patients also feel a mild tingling or pulling sensation in the scalp muscles. It's unusual, but it's not painful for most people.
The first session or two tends to feel the most intense — your scalp is adapting to something it hasn't experienced before. Most patients find it significantly more comfortable by day two or three.
A few things that won't happen: you won't be sedated, you won't feel the magnetic pulse inside your skull, and you won't lose consciousness or feel any kind of electrical shock. There's no recovery period. Most patients drive themselves home.
Headache is the most commonly reported side effect — typically mild and resolving within an hour or two of treatment. It tends to improve as treatment progresses. Scalp discomfort at the stimulation site is also common in early sessions.
If you're anxious about what the sensation will feel like, tell us at your consultation. We can walk you through it in detail and answer questions specific to your sensitivity level.
How do I know which protocol is right for me?
Four questions point most people toward an answer:
1. How much time can you give? If you can only commit one day, the 1-Day Intensive is your path. If five consecutive days works, the 5-Day Intensive has the strongest published efficacy data. If daily visits over six weeks are feasible and you want to use insurance, traditional TMS is the established option.
2. Do you want to use insurance? If yes, traditional TMS is the only protocol currently covered by most plans. If you're open to cash-pay, the accelerated options are often more affordable in total than they first appear — and dramatically faster.
3. How quickly do you need results? Accelerated protocols are designed for rapid response. The SAINT-based 5-Day protocol reported a mean time to remission of 2.6 days in published trials. Traditional TMS typically shows meaningful change at weeks 3–4.
4. Are you traveling for treatment? If you're coming from out of state, the 1-Day or 5-Day Intensive eliminates the need for an extended stay. Many patients fly in, complete their protocol, and fly home within a week.
Still unsure? The protocol quiz takes about two minutes and routes you to a recommendation based on your specific answers.
Do I need a referral from my doctor or psychiatrist?
No. A referral is not required to schedule a consultation or begin treatment at Optimal TMS.
We are a full-service mental health clinic. If you come to us without an existing provider, we can serve as your primary mental health care team — including medication management and talk therapy through our PMHNP-BC. You don't need to have your ducks in a row before reaching out.
That said, if you do have an existing psychiatrist or therapist, we welcome their involvement and will coordinate with them throughout your treatment. Continuity of care matters, and we take it seriously.
Can I continue my medication during TMS?
In most cases, yes. The majority of patients continue their current medications throughout TMS treatment without issue. Antidepressants, anxiolytics, mood stabilizers, and most other psychiatric medications are compatible with TMS.
There are a small number of medications that warrant closer review — particularly those that significantly lower seizure threshold. We'll go through your full medication list during your consultation and flag anything that needs attention.
If you're interested in adjusting or discontinuing medications as part of your treatment plan — either before, during, or after TMS — our PMHNP-BC can provide medication management in-house. You don't need to go elsewhere for that conversation.
What we won't do is give you a generic "ask your doctor" non-answer. If a medication question comes up, we'll give you a real response based on your specific situation.
What happens if TMS doesn't work for me?
We want to answer this honestly, because most clinic websites don't.
TMS doesn't work for everyone. Published response rates for accelerated protocols are high — 87.5% in the ONE-D trial, 78.6% remission in the SAINT trial but those numbers mean a meaningful percentage of patients don't achieve the outcome they were hoping for. That's real, and you deserve to know it going in.
What non-response to TMS typically looks like: no significant change in symptoms by 4–6 weeks following treatment. Some patients report a brief, temporary worsening in the early weeks — this is a known phenomenon and typically resolves. Long-term adverse effects from TMS are rare and not supported by the thousands of studies in the published literature.
If TMS doesn't produce the response you were hoping for, that's not the end of the road. Our team can work with you on next steps — whether that's reassessing your medication regimen, exploring a different protocol, or identifying other evidence-based options. We're not a one-treatment clinic, and we won't send you home without a path forward.
The Science
How does TMS actually work in the brain?
A coil placed against your scalp generates a brief, focused magnetic field that passes painlessly through the skull and induces a small electrical current in the cortical tissue beneath it. That current causes neurons in the targeted region to fire.
When neurons fire repeatedly — session after session — the connections between them strengthen. This is neuroplasticity: the brain's ability to reorganize its own circuitry in response to repeated activity. TMS doesn't introduce a chemical. It creates a pattern of activity, and the brain responds to that pattern by changing.
The primary target for most TMS protocols is the left dorsolateral prefrontal cortex (DLPFC) — a region involved in mood regulation, motivation, and cognitive control that tends to show reduced activity in people with depression. Stimulating it repeatedly shifts its activity patterns and, through its connections to deeper structures in the brain, begins to normalize the broader network.
The result isn't immediate. Neuroplasticity takes time to consolidate — which is why TMS response typically builds over weeks rather than hours. But the changes, when they come, tend to be durable.
What is neuroplasticity and why does it matter for treatment?
Neuroplasticity is your brain's capacity to change to form new connections, strengthen existing ones, and reorganize circuits in response to experience. It's the mechanism behind learning, recovery from injury, and the way therapy and behavioral change produce lasting shifts in how you think and feel.
For decades, the dominant model of mental illness focused on neurochemistry the idea that depression, for example, was primarily a serotonin deficiency to be corrected with medication. That model isn't wrong, exactly, but it's incomplete. What we now understand is that many psychiatric conditions involve disrupted circuit-level communication patterns of connectivity that have become stuck.
Neuroplasticity is how those patterns change. And TMS is one of the most direct tools we currently have for promoting it.
This is the lens through which we think about everything we do at Optimal TMS. Medication can support neuroplasticity. Therapy leverages it. TMS accelerates it. The goal in every case is the same: give your brain the conditions it needs to rewire — and then get out of the way.
What is the SAINT protocol and what did the research show?
SAINT stands for Stanford Accelerated Intelligent Neuromodulation Therapy also referred to as Stanford Neuromodulation Therapy (SNT) in its more recent publications. It was developed at Stanford University and published in JAMA Psychiatry in 2022 by Cole and colleagues.
The trial enrolled patients with treatment-resistant major depressive disorder and delivered 10 iTBS sessions per day for five consecutive days 50 sessions total. The published results: 78.6% remission rate in the active treatment group vs. 13.3% in the sham group Mean time to remission of 2.6 days Rapid, robust response in a population that had previously failed multiple treatments
The original Stanford protocol used individualized fMRI-guided targeting to identify each patient's optimal stimulation site. Our protocol delivers equivalent session volume and timing using validated scalp-based targeting making it accessible without fMRI infrastructure.
We are not affiliated with Stanford University or the SAINT study authors. Our protocol is modeled after their published methodology. When we reference SAINT data, we're citing their research not claiming equivalence we haven't independently validated.
What is D-cycloserine and why do you use it in the 1-Day protocol?
D-cycloserine (DCS) helps activate the NMDA receptor a receptor type critical to synaptic plasticity and learning. At low doses, DCS doesn't produce significant psychological effects on its own. What it does is prime the brain's plasticity machinery: making neurons more responsive to the activity-driven changes that TMS is trying to induce.
Prior randomized controlled trials demonstrated that DCS augmentation of TMS meaningfully improves outcomes boosting remission rates from approximately 18% in the unaugmented group to between 39–75% with DCS. The ONE-D protocol applies DCS before all 20 sessions in a single day, maximizing the neuroplasticity window across the entire treatment course.
DCS has a long and well-documented safety record. It was originally developed as an antibiotic for tuberculosis and has been used in psychiatric research contexts for decades. At the doses used in TMS augmentation it is not a psychiatric drug in the conventional sense it's a neuroplasticity primer.
What's the difference between iTBS and rTMS?
Both are forms of TMS they use the same basic mechanism of magnetic pulse delivery to the brain. The difference is in the pattern and speed of delivery.
rTMS (repetitive TMS): Delivers single pulses at a steady rate — typically 10 pulses per second (10 Hz) for depression protocols. A standard session runs about 38 minutes.
iTBS (intermittent theta burst stimulation): Delivers pulses in rapid triplet bursts (50 Hz) nested within a slower theta-frequency rhythm (5 Hz) a pattern that mimics the brain's own endogenous plasticity signals. A full iTBS session delivers the same therapeutic dose in approximately 3 minutes.
The shorter session time isn't just a convenience feature. It's what makes accelerated multi-session-per-day protocols feasible. You can't deliver ten 38-minute sessions in a day. You can deliver ten 3-minute sessions with 30-minute intervals and that spacing is precisely what leverages the neuroplasticity window.
Published head-to-head data (THREE-D trial, Lancet 2018) showed iTBS to be non-inferior to rTMS for standard once-daily protocols. In accelerated designs, iTBS substantially outperforms rTMS.
Is TMS safe? What are the side effects?
TMS has been studied for decades and has a well-established safety profile. Here's an honest accounting:
Common side effects: Scalp discomfort or mild pain at the stimulation site, particularly in early sessions. Typically improves as treatment progresses. — Headache following sessions. Usually mild, resolves within a few hours, and decreases over the course of treatment. — Facial muscle twitching during stimulation — a normal response to the magnetic field, not a sign of a problem.
Uncommon but possible: Temporary worsening of mood or anxiety in the early phase of treatment. This is known and documented — if it happens, tell us immediately so we can adjust. — Lightheadedness after sessions, particularly early in treatment.
Rare but serious: Seizure. The estimated risk is approximately 1 in 30,000 sessions. This risk is higher in patients with a seizure history, those on medications that lower seizure threshold, or those with certain structural brain abnormalities — which is why we screen carefully before treatment.
What TMS does not cause: Memory loss, cognitive impairment, changes in personality, or systemic side effects. Unlike ECT (electroconvulsive therapy), TMS does not require anesthesia and does not produce a generalized seizure.
Long-term adverse outcomes from TMS are not supported by the published literature. Thousands of clinical studies across more than 30 years of research have not identified lasting harm from properly administered TMS.
How We Compare
How is accelerated TMS different from traditional TMS?
The core difference is session density — and that difference produces meaningfully better outcomes, not just faster ones.
Traditional TMS delivers one session per day, five days per week, for six weeks. This schedule wasn't designed around neuroplasticity optimization — it was designed around clinical convenience and insurance reimbursement structures.
Accelerated TMS delivers multiple sessions per day with precisely timed inter-session intervals — typically 30 minutes. This timing is deliberate: each session opens a neuroplasticity window, and the next session is delivered while that window is still open. The effect compounds. The brain is being pushed to change repeatedly within a single day rather than stimulated once and then left alone for 24 hours.
The published results reflect this difference. Traditional rTMS reports approximately 30–35% remission in real-world practice. The SAINT-based 5-Day protocol reported 78.6% remission. The ONE-D 1-Day protocol reported 71.9% remission. These aren't marginal improvements — they represent a fundamentally more effective use of the same underlying technology.
The tradeoff: accelerated protocols are cash-pay and require a more concentrated time commitment. Whether that tradeoff is right for you is a decision worth making with full information.
How does TMS compare to antidepressants?
They work through different mechanisms, in different timeframes, with different side effect profiles. It's less a competition than a toolkit and for many patients, the most effective path involves both at different points.
Antidepressants work systemically, affecting neurotransmitter availability throughout the brain and body. Response typically takes 4–8 weeks. Side effects weight changes, sexual dysfunction, emotional blunting, sleep disruption are common and can significantly affect quality of life. They require ongoing daily adherence to maintain effect.
TMS works at the circuit level, targeting specific brain networks without systemic chemical exposure. There are no systemic side effects. A completed course of TMS doesn't require ongoing daily treatment to maintain the neuroplasticity changes, once consolidated, tend to be durable.
For patients who have tried antidepressants without adequate relief, or who have found side effects intolerable, TMS offers a genuinely different mechanism not just a different molecule doing the same thing.
For patients currently on medication that's partially working, TMS can augment and extend what the medication is doing. Many patients complete a TMS course and find their existing medication suddenly works better.
How does TMS compare to ketamine or esketamine?
Both TMS and ketamine produce rapid antidepressant effects through mechanisms that promote neuroplasticity. The differences are real and worth understanding.
Speed of onset: Ketamine/esketamine can produce mood changes within hours. TMS response typically builds over days to weeks even with accelerated protocols.
Durability: This is where TMS tends to have an advantage. Ketamine's antidepressant effects often require ongoing maintenance infusions to sustain. TMS-induced neuroplasticity changes tend to be more durable without ongoing treatment.
Side effect profile: Ketamine produces dissociative effects during infusion and requires monitoring. It carries dependence and misuse potential with repeated use. TMS produces no psychoactive effects and no dependence risk.
Cost: Ketamine infusions typically run $400–$800 per infusion, with multiple infusions required for a course. Esketamine (Spravato) is FDA-approved and may have insurance coverage, but access and logistics vary. TMS cash-pay costs are competitive when considered on a per-course basis.
Best use case: Ketamine/esketamine may be the right choice for patients in acute crisis who need rapid stabilization. TMS particularly accelerated TMS is typically the better choice for patients seeking a durable, maintenance-free remission.
Some patients benefit from both, sequenced appropriately. If you're trying to decide between them, that's a conversation worth having with a provider rather than a website.

Why should I choose Optimal TMS over another TMS clinic?
We'll answer this directly, because you asked.
Most TMS clinics offer one protocol: traditional six-week rTMS. They're good at it, and it's a legitimate treatment. But it's yesterday's protocol — the field has moved forward, and most clinics haven't.
We offer accelerated protocols that most clinics don't. The 1-Day Intensive modeled after the ONE-D study and the 5-Day Intensive modeled after the SAINT protocol represent the current leading edge of TMS research. If you're going to do TMS, doing it with the protocols that have the strongest published outcomes is simply the better clinical decision.
Beyond protocols, what makes us different is a philosophy: we believe that educated patients get better outcomes. That's not a marketing line — it's the subject of our lead provider's doctoral research. We invest in your understanding of what's happening and why, before, during, and after treatment. The informed patient who knows what neuroplasticity means and why the inter-session timing matters is a different patient than one who just shows up and sits in a chair.
We're also not a pure-play TMS provider. We offer medication management and talk therapy in-house. If you don't have an existing mental health provider, we can be your complete care team. If you do, we'll work alongside them.
Finally: we'll tell you when TMS isn't right for you. Not every patient who comes through our door should do TMS. We'd rather say that in a free consultation than take your money and hope for the best.
Are your accelerated protocols the same as Stanford's SAINT protocol?
No — and we want to be clear about that.
Our 5-Day Intensive is modeled after the Stanford Neuromodulation Therapy (SNT/SAINT) protocol in its session structure: 10 iTBS sessions per day across five consecutive days, with 30-minute inter-session intervals, for a total of 50 sessions. The timing, stimulation parameters, and session volume are based on the published methodology.
The key difference is targeting. The Stanford protocol used individualized fMRI neuroimaging to identify each patient's optimal stimulation site — a precise but expensive and logistically complex step that requires dedicated imaging infrastructure. Our protocol uses validated scalp-based heuristics for targeting, which is the standard approach used by the large majority of TMS providers in practice.
What this means clinically: we deliver equivalent session volume with the same timing and parameters, without the fMRI individualization. Whether fMRI-guided targeting produces meaningfully better outcomes than standard targeting in an accelerated protocol is an open question in the literature — the answer isn't settled.
We are not affiliated with Stanford University, the Stanford Department of Psychiatry, or the SAINT study authors. When we reference their research, we're citing published science — not claiming their endorsement or institutional equivalence.
