TMS usually involves outpatient sessions over several weeks. When treatment is effective, symptom relief may last for months or longer. According to Mayo Clinic, repetitive TMS is a noninvasive treatment that does not require anesthesia.
Treatment timelines vary based on the protocol, condition being treated, and individual response. Below, you’ll learn how long TMS sessions and treatment courses typically last, when improvement may begin, and what to expect after treatment.
Key Takeaways
- Most TMS sessions last between a few minutes and about 30 to 40 minutes, depending on the treatment protocol.
- A standard treatment course is usually five sessions a week for several weeks.
- Many people who respond to TMS continue feeling better after treatment ends, although some may need maintenance care or another course later.
TMS Session Length and Treatment Timeline
A TMS session usually lasts 3.5 to 40 minutes, depending on the treatment type. At Embracing Life Today, NeuroStar sessions typically take about 19 minutes.
Most patients receive treatment five days a week for several weeks. The first visit may take longer because the clinician maps the treatment area and sets the stimulation level.
| Treatment | Session Time | Schedule |
| Standard TMS | Up to 30-40 minutes | 5 days/week |
| iTBS | About 3.5 minutes | Usually 5 days/week |
| NeuroStar | About 19 minutes | Typically 5 days/week |
TMS is an outpatient treatment and does not require anesthesia. Most patients can return to normal activities after each session.
When Does TMS Start Working?
Most people do not notice improvement after the first session. Changes usually develop over several weeks. Some patients may notice better sleep, energy, focus, or mood first.
Before treatment begins, the clinician conducts a comprehensive medical review to evaluate your overall psychiatric health, ensuring that conditions such as panic disorder or other co-occurring anxiety spectrum issues are factored into your personalized care plan.
How Long Do TMS Results Last After Treatment?
TMS can reduce depression symptoms for months or longer. However, the length of relief varies from person to person.
Research suggests that many people who respond to TMS remain better for 6 to 12 months after treatment. Some stay well for a year or longer. Others may have symptoms return sooner.
As noted by Rachid, F. (2018)
“Recurrent episodes occur in greater than 50% of patients within a one year period despite treatment with antidepressant medications, electroconvulsive therapy and psychotherapy.” – ScienceDirect
Several factors can affect how long the benefits last:
- Response to TMS
- Severity of depression
- Medication and therapy
- Stress and sleep
- Overall mental health
If symptoms return, the clinician may consider medication changes, therapy, maintenance TMS, or another TMS course.
TMS should not be considered a permanent cure. It can provide lasting relief, but depression can return and may need ongoing care.
Regular follow-up helps the clinician track symptoms and decide if more treatment is needed.
What Is TMS Maintenance Treatment?
Some patients stay well after their first TMS course and do not need more treatment. Others may need more sessions if their symptoms return.
Maintenance TMS means having extra TMS sessions after the first course. There is no set schedule for everyone. The clinician may base the plan on symptoms, treatment history, and response to TMS.
| Treatment Stage | Purpose | Typical Approach |
| Acute TMS | Reduce symptoms | 5 sessions/week for several weeks |
| Follow-up care | Track progress | Medication, therapy, or monitoring |
| Maintenance TMS | Support improvement | Extra sessions as needed |
| Retreatment | Treat returning symptoms | Another TMS course if needed |
The American Psychiatric Association recognizes neuromodulation as a standard of care, and utilizing TMS therapy for anxious depression has shown significant clinical efficacy. While acute treatment guidelines are established, protocols for ongoing, routine maintenance sessions vary and continue to be studied
Medication and therapy may also be part of long-term care. The treating clinician can decide if more TMS is needed based on the patient’s symptoms and treatment history.
When Is TMS Booster Treatment Used?
A TMS booster treatment may be considered when depressive symptoms begin returning after an initially successful course, although the exact timing and number of sessions depend on the patient’s clinical response.
Booster treatment is generally different from the initial course because the purpose is not necessarily to start treatment from the beginning. Instead, additional stimulation may be used to reinforce or restore a previous response.
Clinical research has examined repeated TMS courses in patients who responded to an earlier treatment. A study published in Biological Psychiatry found that patients who had previously responded to TMS could respond again during retreatment.
The decision usually considers symptom severity, the duration of the previous response, the degree of improvement achieved during the original course, and whether other treatment changes could address the returning symptoms.
A patient with mild temporary symptoms may receive closer monitoring or medication adjustment instead of immediately returning for TMS. A patient with clear recurrent major depressive symptoms may require a more intensive intervention.
- A booster may be considered after symptoms begin returning.
- A previous positive TMS response supports consideration of retreatment.
- The number of booster sessions is individualized.
- A clinician should reassess the diagnosis before restarting treatment.
TMS retreatment eligibility also depends on whether the patient still meets the clinical and safety requirements for the procedure. Medical implants, neurological history, medication changes, and the current psychiatric diagnosis can affect eligibility.
NeuroStar is not appropriate for every psychiatric condition. Its FDA-cleared indications are specific, and treatment is not intended as first-line therapy for mild depression in patients who are responding adequately to standard treatment.
The goal is therefore not to schedule boosters automatically. The goal is to identify returning symptoms early enough for a clinician to determine whether receiving additional TMS therapy in Coral Gables, FL or at another specialized regional clinic is appropriate.
What Happens If Depression Returns After TMS?
Relapse after TMS can occur, but returning symptoms do not automatically mean that the original treatment failed or that TMS can no longer work.
Depression is commonly a recurrent disorder, so symptom recurrence can occur even after a strong response to treatment. Mayo Clinic notes that TMS may require additional treatment when symptoms return, depending on the clinical situation.
Insights from Arici, C., et al. (2022) indicate
“A 6-month follow-up study on response and relapse rates following an acute trial of repetitive transcranial magnetic stimulation in patients with major depression.” – PubMed
A clinician may first evaluate whether the returning symptoms represent a depressive relapse, another psychiatric condition, medication-related change, sleep disruption, or a major environmental stressor. That assessment helps determine the appropriate next treatment.
If a patient previously responded well to TMS, retreatment may be considered. Published research indicates that some patients can achieve another meaningful response after a repeat course.
The interval between courses can vary substantially. Some patients may remain well for a year or longer, while others may notice symptoms returning earlier.
- Relapse after TMS should prompt clinical reassessment.
- Previous response can support consideration of another TMS course.
- Medication and psychotherapy may continue during follow-up.
- Maintenance or booster treatment may be appropriate for selected patients.
There is also no reliable calendar date at which TMS benefits suddenly disappear. Symptoms tend to change gradually, and early clinical monitoring can help identify a return of depression before symptoms become severe.
Patients should also avoid interpreting temporary fluctuations as definite treatment failure. Mood can vary during and after a TMS course, and clinicians can use standardized symptom assessments to distinguish normal variation from clinically meaningful worsening.
TMS Safety, Side Effects, and Eligibility
Some patients report a temporary increase in symptoms during TMS, sometimes called a “TMS dip.” It does not happen to everyone. Report any new or worsening symptoms to your clinician.
Common Side Effects
Common side effects include:
- Mild headache
- Scalp discomfort
- Temporary pain
These effects are usually mild and improve over time. Serious side effects are rare.
Who Can Receive NeuroStar TMS?
NeuroStar is FDA-cleared for certain conditions, including major depressive disorder, anxiety symptoms in adults with major depressive disorder, and specialized protocols like TMS therapy for OCD.
A clinician reviews your medical history before treatment. Certain metal near the head, some implanted devices, or a history of seizures may affect eligibility.
Insurance coverage varies. Some plans require proof of previous medication trials.
A clinical evaluation can determine if NeuroStar is safe and appropriate for you.
How Long Does TMS Last for Each Patient?
TMS sessions are short, but treatment usually takes several weeks. If TMS works, symptom relief may last for months or longer. The length of relief varies from person to person. If symptoms return, a clinician can decide if more TMS may help.
At Embracing Life Today, NeuroStar Advanced TMS Therapy is an outpatient treatment that does not require medication or anesthesia. Sessions typically last about 19 minutes. Schedule a consultation at Embracing Life Today to learn if TMS may be right for you.
FAQs
How often are TMS maintenance sessions needed after the initial treatment?
TMS maintenance sessions are not required for every patient. The appropriate schedule depends on the patient’s diagnosis, response to the initial treatment course, and changes in symptoms over time. Some patients may receive additional sessions when symptoms return, while others may remain well without maintenance treatment. A clinician should determine whether ongoing sessions are appropriate for each patient.
When might a TMS booster treatment be considered?
A TMS booster treatment may be considered when depressive symptoms return after an initial improvement. A clinician may review the patient’s current symptoms, previous response to TMS, and the length of time since the original treatment course. The clinician can then determine whether additional TMS sessions are appropriate. Patients should not begin booster treatment without a clinical assessment.
How long can TMS remission duration last after treatment?
TMS remission duration varies among patients, and there is no specific period that applies to everyone. Some patients maintain remission for several months, while others experience a return of symptoms sooner. The duration of remission can depend on the patient’s response to treatment, underlying condition, and follow up care. Regular clinical monitoring can help identify changes in symptoms.
What factors affect TMS retreatment eligibility if symptoms return?
TMS retreatment eligibility depends on the patient’s diagnosis, previous response to TMS, current symptoms, and treatment history. A clinician may also consider how long the patient remained improved after the original treatment course. The clinician will assess whether the return of symptoms is significant enough to consider another treatment course. Eligibility should be determined through an individual clinical evaluation.
What should you do if you experience relapse after TMS?
Patients who experience relapse after TMS should contact their treating clinician for an evaluation. The clinician can assess changes in depressive symptoms, review the response to the previous TMS course, and determine whether additional treatment is appropriate. Depending on the assessment, options may include another TMS course, medication changes, psychotherapy, or other treatments that address the patient’s current clinical needs.
