Depression and certain mental health conditions can affect energy, mood, sleep, and daily functioning. While many people benefit from medication or psychotherapy, others may continue experiencing symptoms despite trying standard treatments. In these cases, healthcare providers may discuss additional treatment options.
One option that may be recommended is transcranial magnetic stimulation (TMS). But what is TMS therapy, and how does this non-invasive treatment work? This guide explains the process, safety considerations, and what patients can expect based on information from established medical sources.
What Is TMS Therapy?
Transcranial magnetic stimulation (TMS) is a non-invasive medical procedure that uses magnetic fields to stimulate nerve cells in specific areas of the brain. The treatment is performed without surgery or anesthesia.
According to Mayo Clinic’s overview of transcranial magnetic stimulation, TMS uses magnetic pulses delivered through a coil placed against the scalp to stimulate regions of the brain involved in mood regulation.
Certain TMS devices have been cleared by the U.S. Food and Drug Administration (FDA) for treating major depressive disorder when other treatments have not been effective. The FDA has also cleared specific devices for obsessive-compulsive disorder (OCD) and smoking cessation.
Because the procedure does not involve surgical incisions or implanted devices, it is considered non-invasive.
How TMS Therapy Works
Understanding how TMS therapy works begins with brain activity patterns involved in mood and emotional regulation.
During treatment, an electromagnetic coil placed on the scalp generates magnetic pulses. These pulses create small electrical currents in targeted brain areas.
Cleveland Clinic explains that transcranial magnetic stimulation uses magnetic pulses to activate nerve cells and influence brain activity in areas involved in mood regulation.
Although researchers continue studying the exact mechanisms, repeated stimulation may help influence neural activity and improve communication within brain networks linked to depression.
TMS sessions are typically delivered in a series over several weeks.
Types of TMS Treatment
There are several TMS protocols. Key differences include the pulse pattern, session length, and coil design, which can influence which brain areas are stimulated. A healthcare provider selects the appropriate approach based on the person’s condition and individual needs.
Repetitive TMS (rTMS)
Repetitive TMS is the most commonly used form. It delivers repeated magnetic pulses to targeted brain areas using a coil placed on the scalp. Session details vary depending on the protocol, including pulse frequency and pattern.
Theta-Burst Stimulation (TBS)
Theta-burst stimulation is a patterned form of TMS that delivers rapid bursts of magnetic pulses. TBS sessions are often shorter compared to traditional repetitive TMS protocols.
Deep TMS (dTMS)
Deep TMS uses specialized coil technology designed to stimulate broader and deeper brain regions compared to standard TMS coils. Certain deep TMS systems have received U.S. Food and Drug Administration (FDA) clearance for specific indications, including major depressive disorder, obsessive-compulsive disorder, and smoking cessation.
Accelerated TMS (aTMS)
Accelerated transcranial magnetic stimulation (aTMS) refers to treatment approaches that deliver multiple TMS sessions within a shorter timeframe compared to traditional schedules. One well-known example is Stanford Neuromodulation Therapy (SAINT), an accelerated form of theta-burst stimulation delivered in several brief sessions per day over approximately five days in specialized settings.
In 2025, the U.S. Food and Drug Administration (FDA) also cleared an accelerated deep TMS protocol for major depressive disorder. Treatment protocols and availability may vary depending on the device and clinical practice.
TMS Benefits
When discussing TMS benefits, it’s important to remain realistic and evidence-based.
Potential advantages may include:
- Non-invasive treatment without surgery
- No need for anesthesia
- Outpatient sessions
- Ability to return to normal daily activities after treatment
Mayo Clinic reports that TMS does not require sedation and is generally well tolerated by many patients.
Individual results vary, and not everyone responds to treatment.
How to Prepare Before Your TMS Session
Preparation usually involves a clinical evaluation.
Before treatment, providers may:
- Review medical and psychiatric history
- Discuss medications and supplements
- Screen for metal implants or implanted devices
- Assess seizure risk
Because TMS uses magnetic fields, certain implanted devices may affect eligibility. Cleveland Clinic advises informing your provider about any medical devices or prior neurological conditions.
What to Expect During Treatment
Knowing what to expect during treatment can help patients feel more prepared.
During a session:
- You sit in a chair while an electromagnetic coil is placed against your scalp.
- You may feel tapping sensations and hear clicking sounds.
- You remain awake and alert throughout the procedure.
Mayo Clinic notes that treatment sessions are typically performed daily, five times per week, for several weeks depending on the protocol.
After treatment, most people can resume normal activities unless otherwise instructed by their provider.
Important Considerations
TMS therapy is a medical treatment that should only be considered in consultation with a licensed healthcare professional. Treatment decisions should be based on individual medical history, diagnosis, and professional evaluation.
