Why a TMS Consultation Is a Conversation, Not a Decision
The most useful questions to ask during a TMS consultation are the ones that help you understand whether treatment may be appropriate for your situation, how a session works, what side effects to expect, and how scheduling and follow-up are handled. A TMS consultation is an evaluation and information-sharing visit, not a commitment to treatment. It typically includes a review of your medical and mental health history, your prior treatment history, and a discussion of whether TMS may be appropriate. Appropriateness is determined by a qualified clinician, and this article provides general education only, not individualized medical advice.[source][source]
It helps to arrive with a written list of questions organized around a few themes: candidacy, safety screening, the session itself, side effects, scheduling and follow-up, and access to care. The sections below offer question sets you can adapt to your own health history and concerns. No single question is more important than the others; the goal is to leave the visit with a clearer picture of what TMS involves and what the next step, if any, might be.
Questions About Whether TMS May Be Appropriate for You
TMS is a noninvasive, FDA-approved neuromodulation treatment for major depressive disorder (MDD), and it is commonly used for treatment-resistant depression (TRD) and other neuropsychiatric conditions that have not responded adequately to medications. It uses focused magnetic pulses delivered through a coil placed on the scalp to stimulate specific brain regions involved in mood regulation, particularly the left dorsolateral prefrontal cortex. According to one academic program, TMS may be considered for patients who have major depressive disorder or treatment-resistant depression with an inadequate response to antidepressant medications, who have not tolerated or benefited from pharmacologic treatments, who prefer a noninvasive, non-systemic treatment option, or who do not require the rapid symptom relief provided by other interventional treatments. All patients undergo a comprehensive evaluation to confirm the diagnosis, review prior treatment history, and assess the appropriateness of TMS therapy.[source]
Questions worth asking include: What conditions does TMS treat at this clinic? What prior treatments are typically expected before TMS is considered? How is treatment-resistant depression defined in this context? What factors in my history would make TMS more or less appropriate? The clinician's assessment, not your self-assessment, determines appropriateness, and no outcome can be guaranteed. A literature review has reported response rates to TMS ranging between 50% and 55% and remission rates between 30% and 35% in patients with major depression, but individual results vary and these figures are not a prediction of your own outcome.[source]
Questions About Safety Screening and Medical History
Safety screening is a core part of the consultation. Patients with any type of non-removable metal in their heads, with the exception of braces or dental fillings, may not be able to receive TMS; failure to follow this rule could cause the metal object to heat up, move, or malfunction, resulting in serious injury or death. Screening is performed by trained clinicians, and you should not try to screen yourself. Questions to ask include: How will my seizure and neurologic history be assessed? Do any of my medications or substances affect seizure threshold? Do I have any metal or implanted devices that could affect safety? What happens if a safety concern is identified?[source]
During your initial consultation, a thorough medical and mental health history will be taken to determine if TMS might be safe and appropriate for you, and the clinic should also provide detailed information about the treatment process, risks, benefits, and side effects. If you have questions about a specific implant, device, or medication, raise them directly with the clinician rather than relying on general information.[source]
Questions About What Happens During a TMS Session
During a TMS treatment session, an electromagnetic coil is placed against the scalp, and the electromagnet delivers a pulse that stimulates nerve cells in a region of the brain involved in controlling mood. For depression, the target is the dorsolateral prefrontal cortex, one of the major control centers of the brain. Because TMS uses magnetic pulses, patients must remove any magnetic-sensitive objects such as jewelry, hearing aids, and credit cards prior to treatment. Patients are required to wear earplugs during treatment for comfort and hearing protection, as the TMS device produces a loud clicking noise with each pulse. Patients are seated in a comfortable chair and are awake for the entire session.[source]
During the first session, several measurements are made to ensure the TMS coil will be properly positioned over the correct brain region. The TMS physician measures a motor threshold by administering several brief pulses over the left side of the brain. The motor threshold is the minimum amount of power necessary to make the patient's thumb twitch, and it varies from person to person; measuring it helps the physician determine the correct amount of energy required to stimulate the brain. Once the motor threshold is determined, the coil is placed directly over the dorsolateral prefrontal cortex, an area about the size of a golf ball located toward the front of the brain. During treatment, the device taps on the scalp over this region, and the patient can hear a series of clicking sounds and feel a strong tapping sensation on the scalp. Useful questions include: What is motor threshold, and how is it determined? Where is the coil placed, and why? Will I be awake during treatment? What will I hear and feel? How long does a session last? Session length and protocol can vary by device, indication, and individualized plan.[source]
Questions About Side Effects and Tolerability
TMS is well tolerated and associated with very few side effects. Commonly reported side effects include headaches, which are usually mild and diminish over the course of treatment, and painful scalp sensations or facial twitching with TMS pulses, which also tend to improve over the course of treatment; adjustments can be made immediately in coil positioning to reduce discomfort. The most serious risk of TMS is seizures, but seizure risk is rare, and clinics follow up-to-date safety guidelines designed to minimize that risk. Questions to ask include: How often do headaches or scalp discomfort occur, and how long do they typically last? What adjustments can be made if I find a session uncomfortable? How does this clinic minimize seizure risk? Side effects are typically transient and serious adverse events are rare, but no risk-free experience can be guaranteed.[source]
A review of TMS in depression also describes commonly reported adverse effects such as transitory or recurrent headaches that respond to over-the-counter analgesics, a tingling sensation on the scalp and face, and ipsilateral lacrimation, with seizure activity being rare. If you experience side effects that concern you, discuss them with the treatment team rather than stopping or adjusting anything on your own.[source]
Questions About Scheduling, Treatment Course, and Follow-Up
TMS is administered in an outpatient clinical setting and does not require anesthesia or sedation. At one academic program, the treatment process includes an initial motor threshold determination and individualized treatment planning session, followed by daily treatment sessions administered five days per week. A standard course of TMS consists of 36 total treatment sessions, typically delivered as 20-minute sessions five times per week for six weeks, followed by a tapering phase to sustain antidepressant effects and reduce relapse risk: three sessions during the first taper week, two sessions during the second taper week, and one session during the final taper week. Treatment schedules may be adjusted based on clinical response and tolerability.[source]
Other sources describe a typical course of at least 30 treatments, with individual sessions varying in length depending on the type of TMS utilized, and a protocol lasting anywhere from one week up to six to eight weeks depending on the number of treatments per day. Because session counts and schedules vary by device, indication, protocol, and clinical response, ask the clinic directly: How many sessions are typical here? How many visits per week? How long might a full course last? Are accelerated protocols offered? What follow-up or maintenance options exist after the acute course? Confirm the clinic's specific offerings rather than relying on general numbers.[source]
Questions About Costs, Insurance, and Access
Access to TMS usually begins with a conversation with your mental health or primary care provider, who can submit a consultation request to a TMS clinic; a staff member then contacts you for an in-person or video-based consultation. Questions worth asking include: Does this clinic accept my insurance? What documentation may be needed for a referral or prior authorization? What is the process for getting started? Are telemedicine options available for any part of the evaluation or follow-up? Coverage and cost details are time-sensitive and vary by plan, so confirm them directly with the clinic; this article does not provide pricing or coverage guarantees.[source]
How to Prepare for Your TMS Consultation
A little preparation can make the consultation more productive. Bring a list of your current medications and prior treatments, write down your questions in advance, and consider bringing a caregiver or support person if that would help you remember and process the information. Remember that the consultation is a chance to gather information rather than make an immediate decision, and that this article is general education and does not replace individualized medical evaluation.[source][source]

Frequently Asked Questions
What is the most important question to ask during a TMS consultation?
There is no single most important question. The key is to ask about candidacy, safety screening, the session process, side effects, scheduling and follow-up, and access to care. Prioritize the questions that matter most for your own health history and concerns, and remember that the clinician's assessment determines whether TMS is appropriate.
Can I get TMS if I have metal implants?
Patients with any type of non-removable metal in their heads, with the exception of braces or dental fillings, may not be able to receive TMS. Safety screening is performed by trained clinicians, so discuss your specific implants or devices directly with the clinic rather than trying to assess this yourself.
How many TMS sessions will I need?
A typical course may involve multiple sessions per week over several weeks. One academic program describes a standard course of 36 total sessions delivered as 20-minute sessions five times per week for six weeks, followed by a tapering phase, while other sources describe at least 30 treatments with sessions varying in length depending on the type of TMS. Exact counts and schedules vary by device, indication, protocol, and clinical response, so ask the clinic about its specific protocol.
Is TMS covered by insurance?
Coverage varies by plan and is time-sensitive. Ask the clinic directly about insurance acceptance and what documentation may be needed for a referral or prior authorization. This article does not provide pricing information or coverage guarantees.
What side effects should I ask about?
Ask about common side effects such as headaches and scalp discomfort, how often they occur, how long they typically last, and what adjustments can be made. Also ask about the risk of seizure and how the clinic minimizes it. Side effects are typically transient and serious adverse events are rare, but no risk-free experience can be guaranteed.
Can I drive myself home after a TMS session?
TMS does not require sedation or anesthesia, and patients are fully awake and aware during treatment. There is no recovery time, so patients can drive to and from appointments and return to usual activities as soon as treatment is completed. Confirm with your clinic based on your individual situation.
What should I bring to my TMS consultation?
Bring a list of current medications and prior treatment history, a written list of your questions, and a caregiver or support person if that would be helpful. The consultation is for information gathering, and no decision needs to be made immediately.
