Learn how TMS therapy can help with depression, including who may benefit, how treatment works, what to expect, and possible side effects.
Depression can affect far more than mood. It can change sleep, concentration, motivation, relationships, work, and the ability to enjoy everyday life.
Many people improve with psychotherapy, antidepressant medication, or a combination of treatments. But not everyone responds to the first approach they try.
For adults with major depressive disorder who have not responded adequately to antidepressant treatment, TMS therapy for depression may be an option worth discussing with a qualified healthcare provider.
TMS, or transcranial magnetic stimulation, is a non-invasive treatment that uses magnetic pulses to stimulate specific areas of the brain involved in mood regulation. It does not require surgery, and patients remain awake during treatment.
But what exactly happens during TMS? Who is it for? And what can someone realistically expect?
Let’s take a closer look.
Transcranial Magnetic Stimulation is a non-invasive brain stimulation treatment that uses magnetic fields to influence nerve cells in specific areas of the brain.
Unlike electroconvulsive therapy (ECT), TMS does not involve inducing a seizure. Patients generally remain awake and able to communicate throughout the session.
TMS therapy for depression is most commonly considered for people with major depressive disorder who have not achieved adequate improvement with other treatments. A clinical evaluation is necessary to determine whether it is appropriate for an individual.
The exact mechanisms behind TMS are still being studied, but the treatment is designed to influence activity in specific brain circuits associated with mood.
During a session, the TMS device delivers a series of magnetic pulses through the scalp. These pulses stimulate targeted areas of the brain. Over a course of repeated treatments, this stimulation may influence neural activity and connectivity within circuits involved in depression.
It is important to be careful with the language here. TMS does not simply “reset” the brain, and it isn’t accurate to promise that it will restore everyone’s mood or eliminate depression. Treatment response varies from person to person.
A provider may consider factors such as:
TMS isn’t necessarily the next step for everyone with depression. That’s why an assessment matters.
One of the characteristics that distinguishes TMS from some other interventions is that it does not require surgery.
The magnetic stimulation is delivered externally through a device positioned against the scalp.
TMS is generally administered while the patient is awake and alert.
This means it does not require the type of general anesthesia associated with some procedures.
Rather than circulating throughout the body like an oral medication, TMS delivers magnetic stimulation to a targeted area of the brain.
This localized approach is one reason TMS has become an important area of interest in depression treatment.
Some people continue to experience significant depressive symptoms despite trying antidepressant medications or psychotherapy.
For appropriately selected patients, TMS therapy for depression can provide another treatment option to discuss with a mental health professional.
TMS sessions are generally performed in an outpatient clinical setting.
After a session, many patients can return to their normal activities without a lengthy recovery period.
However, individual circumstances can vary.
A typical session begins with the patient sitting comfortably in a treatment chair.
The clinician positions the TMS device against the scalp and determines the appropriate treatment location and stimulation settings. During treatment, you may hear clicking sounds and feel tapping or pressure around the treatment area.
Some people experience scalp discomfort or a headache during or after treatment. Your provider can make adjustments when appropriate to improve comfort.
Importantly, you remain awake during the procedure. After the session, your provider will let you know whether you can return to your usual activities.
TMS is not usually a one-session treatment.
Because its effects are associated with repeated stimulation, treatment generally involves multiple sessions scheduled over several weeks. The exact schedule depends on the specific TMS protocol, the treatment device, and the patient’s circumstances.
Some newer protocols can deliver treatment in shorter time frames, while traditional protocols may involve sessions on multiple days each week. Your provider should explain the recommended schedule before treatment begins.
TMS is generally considered well tolerated, but side effects can occur.
Common effects may include:
Most side effects are temporary, but your provider should explain the potential risks before treatment.
Although uncommon, more serious complications can occur. Your clinician will review your medical history and treatment suitability before beginning TMS.
TMS and antidepressant medication work differently. Antidepressants are systemic medications that affect neurotransmitter systems throughout the body. TMS uses magnetic stimulation directed at specific brain regions.
That doesn’t mean one approach is automatically better than the other.
For some people, medication may be appropriate. Others may benefit from psychotherapy, TMS, a combination of treatments, or another treatment strategy.
The right choice depends on the individual’s diagnosis, treatment history, medical circumstances, preferences, and response to previous care.
No. TMS requires careful screening. Certain medical conditions, implanted devices, or metal in or around the head may affect whether someone is an appropriate candidate.
Your healthcare provider should review your medical history, medications, previous treatments, and any relevant implants or medical devices before treatment.
TMS can reduce depressive symptoms in some appropriately selected patients, particularly those with major depressive disorder who have not responded adequately to previous treatments. However, treatment response varies, and no treatment guarantees remission.
The number of sessions depends on the treatment protocol and individual circumstances. Traditional treatment courses commonly involve repeated sessions over several weeks, while newer protocols may use different schedules.
TMS is generally not considered painful, but some people experience scalp discomfort, tapping sensations, or headaches during or after treatment. Your provider can discuss ways to improve comfort.
Many people can resume their usual activities after a TMS session. Because individual circumstances differ, your treatment provider can advise you about your specific situation.
Not necessarily. TMS can be used as part of a broader depression treatment plan. Whether medication should be continued, changed, or stopped is a decision that should be made with your prescribing clinician.
The timeline varies. Some people notice changes during a treatment course, while others may require more sessions before experiencing meaningful improvement. Your provider can monitor your symptoms throughout treatment.
Choosing a depression treatment can feel complicated, particularly when previous approaches haven’t provided the improvement you hoped for.
If you’re considering TMS therapy for depression, a qualified provider can evaluate your concerns, review previous treatments, explain what TMS involves, and determine whether it may be an appropriate option for you.
Treatment should never be reduced to a single procedure. A comprehensive approach may include psychotherapy, medication management, TMS, or other appropriate behavioral healthcare services.
Living with depression that hasn’t improved with previous treatment can be exhausting. It can also leave you wondering whether you’ve simply run out of options. You haven’t necessarily reached the end of the road.
TMS therapy for depression is one evidence-based treatment option that may be appropriate for some people with major depressive disorder, particularly when previous treatments have not provided adequate relief.
It isn’t a guaranteed solution, and it isn’t right for everyone. But for the right patient, it may offer another path worth exploring.
If depression continues to affect your mood, relationships, work, sleep, or everyday life, Pinnacle Behavioral Healthcare can help you explore whether TMS or another evidence-based treatment approach may be appropriate for your needs.
