What Is TMS Therapy and How Does It Work?

About one in three people treated for major depressive disorder do not get adequate relief from antidepressants (National Institutes of Health). For those patients, the assumption that medication is the only option can delay effective care by years. At DreamWork Wellness Center, TMS therapy is one of the core treatments we offer at our Frisco and Sherman, TX locations for patients who have been through the standard options and are still looking for a way forward.

What TMS Therapy Actually Is

TMS stands for transcranial magnetic stimulation, a non-invasive treatment that uses a device placed against the scalp to deliver short, focused magnetic pulses to targeted areas of the brain. Those pulses generate small electrical currents in the underlying neural tissue, stimulating neurons in regions that depression has underactivated. The process does not require surgery, anesthesia, or sedation. Patients sit in a chair, remain fully awake throughout, and leave the office under their own power when the session ends (Mayo Clinic).

The device we use at DreamWork is the NeuroStar Advanced TMS system, which delivers precise, repeatable stimulation to the left prefrontal cortex. The prefrontal cortex is the region of the brain most consistently linked to the emotional and motivational symptoms of depression, and reduced activity there is one of the most well-documented neurological patterns associated with the condition. The magnetic field produced during treatment is similar in strength to that of an MRI machine. Sessions run approximately 30 to 60 minutes, and a full treatment course typically involves five sessions per week for four to six weeks.

How TMS Works in the Brain

The reason TMS takes weeks to produce its full effect comes down to neuroplasticity, the brain’s capacity to reorganize itself by forming and strengthening new neural connections. Depression is associated with reduced activity in circuits responsible for mood regulation, motivation, and emotional processing. Repeated stimulation of those circuits encourages them to become more active and better connected over time, which is why most patients notice changes building gradually across the treatment course rather than arriving all at once (National Institutes of Health).

This mechanism is different from how antidepressants work. SSRIs and SNRIs increase the availability of serotonin and norepinephrine in the brain through the bloodstream, affecting neurotransmitter levels broadly. TMS activates specific neural circuits directly, without introducing any substance into the body. It does not produce the systemic effects associated with psychiatric medication, and it does not affect sleep, appetite, or other functions the way many antidepressants can. For patients who have had difficulty tolerating medication side effects, that distinction matters.

FDA Clearance and the Conditions We Treat With TMS

The FDA first cleared TMS for major depressive disorder in 2008, and the clinical evidence base has grown significantly since. The FDA has also cleared TMS for obsessive-compulsive disorder, and research continues to support its use for PTSD, anxiety, and migraines (National Institutes of Health). At DreamWork, we offer TMS for all of these conditions across our Frisco and Sherman locations.

Every TMS patient at our practice is evaluated by our medical team before beginning treatment. Our medical director, Dr. Jahi Anderson, is a board-certified psychiatrist with more than fifteen years of clinical experience in mood disorders, anxiety, PTSD, and substance use disorders. He completed his psychiatric residency at Robert Wood Johnson Medical School and Cooper University Hospital, where he served as chief resident. Understanding your full history before recommending any treatment is how we work. No one begins TMS at DreamWork without a thorough evaluation first.

What to Expect During a TMS Course

A TMS session at DreamWork follows a consistent structure. The TMS device is positioned against the left side of your scalp, and treatment begins. During the session, you will hear a series of clicking sounds and feel a tapping sensation on your head as the magnetic pulses are delivered. The sensation is noticeable but not painful for most patients. Mild scalp discomfort at the treatment site is the most commonly reported side effect, and for most people it diminishes after the first few sessions as they adjust to the process (Mayo Clinic).

There is no recovery period. You drive yourself to and from appointments, return to work the same day, and continue your normal routine throughout the entire treatment course. There is no sedation, no anesthesia, no memory disruption, and no medication involved at any point. This makes TMS particularly practical for patients who cannot take time away from work or family responsibilities.

Treatment schedules run five days per week for four to six weeks. Results vary by individual. Some patients begin noticing changes within the first two weeks; others see the full benefit build in the weeks following the conclusion of the course. Our team monitors your progress throughout and communicates with you about what you are experiencing.

Cost and Insurance Coverage

We know that cost is a real factor in whether people can access care, and we think it is worth addressing plainly. At DreamWork, we accept all major insurance plans, including Medicare, Blue Cross Blue Shield, Aetna, UnitedHealthcare, Cigna, United Medical Resources, Magellan, and TriWest Healthcare Alliance. Insurance coverage for TMS for major depressive disorder has expanded considerably in recent years, and many plans now cover TMS when specific clinical criteria are met.

Our team handles prior authorization and insurance verification before your first session begins. You will know your financial responsibilities before any commitment is made. If you have questions about your specific plan, call us at 214-592-8159 and our front desk team will walk through the details with you.

TMS pricing is not posted on our site because coverage varies significantly by plan. We do not want patients to make assumptions based on a number they saw online. A direct conversation is always the clearer path.

Is TMS Right for You?

TMS is generally considered for adults who have not had adequate results from one or more antidepressant trials. It is also an option for patients with PTSD, anxiety, OCD, and migraines, and for patients who prefer a treatment that does not involve systemic medication. Patients with certain metallic implants in or near the head, a history of epilepsy or unprovoked seizures, or certain other neurological conditions may not be candidates, which is why the evaluation process matters.

The right starting point is a conversation about your full treatment history. Understanding who qualifies for TMS therapy is the best way to get a clear, honest answer about whether TMS fits your situation. We do not push any single treatment as the answer for every patient.

Frequently Asked Questions

How long does it take for TMS to start working?

Most patients do not experience the full effect of TMS until several weeks into the treatment course, because the therapy works by gradually strengthening neural pathways rather than producing an immediate chemical shift. Some patients report noticing a change in mood or energy within the first two weeks; others see continued improvement in the weeks after the final session. Results vary by individual.

Does TMS hurt?

The most commonly reported sensation during TMS is a tapping or knocking feeling on the scalp at the treatment site. Mild scalp discomfort during the session is the most frequently reported side effect, and for most patients it becomes easier to manage after the first few sessions as they adjust. There is no pain after the session ends, and no sedation or anesthesia is involved at any point (Mayo Clinic).

Is TMS covered by insurance?

TMS for major depressive disorder is covered by many major insurance plans, including Medicare, when clinical criteria are met. At DreamWork, our team handles prior authorization and insurance verification before treatment begins so patients understand their out-of-pocket costs before committing to anything. Call us at 214-592-8159 to ask about your specific plan.

Who is not a good candidate for TMS?

Patients with certain metallic implants in or near the head, a history of epilepsy or unprovoked seizures, or certain other neurological conditions may not be candidates for TMS. A thorough evaluation is the necessary first step, and candidacy is assessed individually at DreamWork before any treatment is recommended.

Can TMS be used while I am on medication?

In many cases, yes. Some patients continue their existing psychiatric medications throughout a TMS course; others work with their provider on adjustments. The approach is determined individually, in discussion with your provider, based on your history and goals. Discuss your current medications with our team at your consultation.
