TMS Therapy in Gilbert: A Non-Medication Option for Treatment-Resistant Depression
TMS therapy, or transcranial magnetic stimulation, uses targeted magnetic pulses to stimulate specific brain regions and requires no medication, no sedation, and no downtime of any kind (Mayo Clinic). The FDA cleared TMS for major depressive disorder in 2008, giving it a clinical evidence base that now spans nearly two decades (National Institutes of Health). At Core Self in Gilbert, TMS is one of two advanced treatments we offer for patients whose depression has not responded to standard antidepressants.
What TMS Actually Is
TMS is a procedure that delivers focused magnetic pulses to targeted areas of the brain from a device placed against the scalp. Those pulses stimulate neurons in the prefrontal cortex, the region most associated with mood regulation, which in patients with depression is typically underactive. The pulses are not electricity and do not involve any physical penetration of the scalp or skull. Patients remain awake and seated throughout.
The closest everyday comparison for what TMS feels like is a light tapping or knocking sensation at the point of stimulation. Most patients adapt to this within the first few sessions. It is not painful for the majority of patients, and no anesthesia or sedation is required before, during, or after treatment.
Before beginning TMS at Core Self, your provider conducts an initial brain mapping session. This maps the specific location on your scalp that corresponds to the motor cortex, which is then used to precisely calculate where the treatment coil should be positioned for your treatment target. This step is not optional; accurate targeting matters for clinical outcomes, and we do not skip it.
What Conditions TMS Treats at Core Self
TMS is FDA-cleared for major depressive disorder and for obsessive-compulsive disorder. At Core Self, we offer TMS for patients with major depressive disorder who have not responded adequately to antidepressant medication, which is the population for whom the evidence base is strongest.
The FDA's clearance for TMS in depression was based on clinical trials demonstrating meaningful improvement in depressive symptoms in patients who had not responded to prior medication treatment (National Institutes of Health). That clearance has since been extended to OCD as a second indicated condition, reflecting the growing body of evidence supporting TMS across more than one psychiatric diagnosis.
TMS is not appropriate for every patient. Patients with certain types of metal implanted in or around the head, active seizure disorders, or other specific contraindications may not be candidates. We review medical history carefully before recommending TMS, and the evaluation process at Core Self is thorough before any treatment begins.
For a broader look at what TMS has meant for patients managing depression, our post on TMS therapy as a breakthrough for depression covers the clinical context in more depth.
What the Treatment Protocol Looks Like
A standard TMS course at Core Self involves sessions five days a week, Monday through Friday, for four to six weeks. Each session runs between 20 and 40 minutes. Because there is no sedation involved, patients drive themselves to and from every appointment. There is no recovery time required after sessions, and patients return to work, school, or their regular routine immediately.
The consistency of daily sessions is a meaningful consideration for anyone evaluating whether TMS fits their life. We hear this concern regularly. The daily schedule is one of the most common reasons patients hesitate, and we think it deserves a straightforward answer: the session length is short, the visits are manageable for most patients working or parenting full-time, and the treatment period has a defined end point. It is not open-ended. Most patients complete a full course within six weeks and then move into a monitoring or maintenance phase based on their response.
Safety and Side Effects
TMS has a well-established safety profile, and the side effects most commonly reported are mild and localized (National Institute of Mental Health). Scalp discomfort or mild headache at or near the site of stimulation is the most frequently reported experience, particularly in the first few sessions. For most patients, this decreases significantly as the course progresses.
Serious adverse events from TMS, including seizure, are rare. The risk of seizure associated with TMS is considered low, and precautions are built into the screening process to identify patients whose history may elevate that risk. There are no systemic side effects from TMS because the treatment does not enter the bloodstream. This is one of the features that makes TMS a meaningful option for patients who have experienced significant side effects from antidepressants.
TMS does not cause memory loss, does not require recovery time, and does not affect a patient's ability to drive or operate normally after a session. These are among the most common questions patients ask before starting, and the answers are consistent across the published evidence base (National Institute of Mental Health).
Insurance Coverage and What to Expect Financially
TMS therapy is covered by most major insurance plans, including Medicare and Tricare, for patients who meet clinical criteria. Criteria typically include a documented history of inadequate response to antidepressant medication, which is standard for patients pursuing TMS. Core Self's team handles insurance verification and prior authorization before treatment begins, so you have a clear picture of your financial responsibility before your first session.
Cost is one of the most common reasons patients delay pursuing TMS, and the insurance landscape for TMS has changed substantially. Coverage has expanded considerably over the past several years as the clinical evidence base has grown. If you have tried antidepressants and not found sufficient relief, there is a reasonable chance your insurance covers this treatment. The only way to find out for certain is to verify your specific plan's benefits, which our team does as a standard part of the intake process.
Cash-pay and patient financing options are available for patients whose insurance does not cover TMS or who are paying out of pocket.
Every patient at Core Self begins with a free consultation before any formal evaluation or treatment is scheduled. We encourage every patient to discuss their options openly with their provider and to make any treatment decisions collaboratively. Results vary by individual, and TMS is not appropriate for every patient or every presentation of depression. For patients who also want to explore a complementary approach, SPRAVATO® is a second advanced treatment available at Core Self for eligible patients.
Frequently Asked Questions
Does TMS hurt?
Most patients describe a tapping or knocking sensation at the stimulation site during sessions. Mild scalp discomfort is the most commonly reported side effect, particularly in the first week, and tends to decrease as the treatment course progresses. TMS does not involve anesthesia, needles, or any physical penetration of the scalp. Most patients tolerate it well enough to drive themselves home after every session.
How many sessions will I need?
A standard TMS course at Core Self involves daily sessions, five days a week, for four to six weeks. The initial brain mapping session is completed before treatment begins. After the course concludes, your provider will assess your response and discuss whether any maintenance sessions are appropriate.
Will my insurance cover TMS?
TMS is covered by most major insurance plans, including Medicare and Tricare, for patients who meet clinical criteria. Our team verifies your benefits and handles prior authorization before treatment begins. If your plan covers TMS, we will confirm that before you commit to anything.
Can I keep taking my antidepressant during TMS?
In many cases, yes. Whether to continue, adjust, or pause any existing medication during a TMS course is a clinical decision made collaboratively with your provider based on your individual history and situation. We do not make blanket recommendations, and the evaluation process addresses this specifically.
Is TMS the same as electroconvulsive therapy?
No. TMS and ECT, or electroconvulsive therapy, are different treatments. ECT involves passing an electrical current through the brain and requires general anesthesia. TMS uses magnetic pulses, requires no anesthesia, and does not cause a seizure as part of its mechanism. They are distinct procedures with different protocols, different patient populations, and different evidence bases.
