TMS can improve depression for varying periods, with outcomes shaped by symptom response and ongoing care; follow-up helps identify relapse and consider maintenance treatment.
How Long Do TMS Results Last? A Indiana Guide to Follow-Up Care
Transcranial magnetic stimulation (TMS) is a non-invasive treatment most commonly used for major depressive disorder. A standard course often involves weekday appointments over several weeks, followed by a review of how symptoms have changed and what support may be needed next.
For many people, improvement after TMS can last for a meaningful period. However, there is no single timetable that applies to everyone. Depression can be a recurring condition, and some people remain well after treatment while others notice symptoms returning over time.
Planning follow-up care before the end of a TMS course can make it easier to respond early if mood, sleep, motivation or anxiety begin to worsen.
What does “lasting results” mean after TMS?
A TMS course may lead to a response, meaning symptoms improve, or remission, meaning symptoms reduce to a level where they are minimal or no longer meet the usual threshold for depression. These are different outcomes, and both can be valuable.
How long improvement lasts depends on several factors, including:
- Whether depression has been recurrent or difficult to treat in the past
- How fully symptoms improved during the TMS course
- Ongoing medication, therapy or other mental health support
- Sleep, physical health, substance use and major life stress
- Whether anxiety, trauma symptoms, chronic pain or other conditions are also present
- How quickly early signs of relapse are recognised and addressed
TMS is not generally viewed as a one-time cure for depression. Instead, it can be one part of a longer-term care plan. Some people complete treatment and need no further TMS for a long time. Others may benefit from occasional maintenance sessions or another full course if depression returns.
Relapse can happen, but it is not a personal failure
A relapse means that depressive symptoms return after a period of improvement. It does not mean TMS “failed”, nor does it mean that someone has done anything wrong. Depression often follows a fluctuating course, and people can need different levels of support at different times.
Early signs can vary from person to person. They may include:
- Sleeping much more or less than usual
- Loss of interest in routine activities
- Increasing fatigue or difficulty concentrating
- Withdrawing from family, friends or work
- Feeling more hopeless, irritable or anxious
- Changes in appetite
- Missing medication, therapy or follow-up appointments
- Thoughts of self-harm or suicide
It can help to write down the symptoms that tended to appear before previous depressive episodes. Patients may also wish to ask a partner, family member or trusted friend what changes they have noticed in the past. This creates a more practical relapse plan than waiting until symptoms become severe.
If thoughts of self-harm or suicide are present, seek urgent help through emergency services, a crisis service or a local emergency department.
Follow-up after a TMS course
Your TMS clinician will usually arrange a review at the end of treatment or shortly afterwards. This appointment is an opportunity to look at progress, discuss any remaining symptoms and agree on the next stage of care.
Follow-up plans vary, but may include contact with:
- The TMS clinic or prescribing clinician
- A psychiatrist
- A GP or primary care clinician
- A therapist, counsellor or psychologist
- Other services involved in your care, such as pain, sleep or substance-use support
It is useful to ask who will take responsibility for each part of the plan. For example, your TMS clinic may monitor the immediate post-treatment period, while a psychiatrist manages medication and a therapist provides ongoing talking therapy.
Consider keeping a simple record of mood, sleep, activity and anxiety for the first months after treatment. This does not need to be detailed. A brief weekly note can make it easier to spot patterns and give your clinician a clearer picture at review appointments.
Maintenance TMS: what is it?
Maintenance TMS refers to additional sessions given after an initial course, with the aim of helping sustain improvement or reducing the chance of symptoms returning. There is no single maintenance schedule that is right for every patient.
Some people do not need maintenance sessions. Others may have sessions spaced out over time, or may be offered a small number of sessions when early symptoms reappear. The approach depends on clinical history, previous response to TMS, practical access to appointments and the treating clinician’s assessment.
Maintenance treatment is different from a full new course of TMS. It is generally considered when a person is well or mostly well but may benefit from additional support to maintain progress.
Questions to discuss with a clinic include:
- Do you recommend routine maintenance sessions after my course?
- What signs would suggest that I should contact the clinic sooner?
- Would a brief set of sessions be considered if symptoms start returning?
- Who decides whether maintenance TMS is appropriate?
- How would medication or therapy fit alongside maintenance sessions?
- What might my insurance plan require before covering further treatment?
The evidence and clinical practice around maintenance TMS continue to develop. A personalised plan is usually more useful than assuming everyone will need the same schedule.
Re-treatment if depression returns
Re-treatment means having another structured course of TMS after a return of clinically significant depressive symptoms. People who responded well to TMS previously may wish to discuss re-treatment if depression recurs.
A clinician will normally reassess symptoms rather than automatically restarting TMS. They may consider changes in medication, therapy, physical health, sleep, alcohol or drug use, recent stressors and any new diagnoses. They will also review whether TMS remains suitable and whether another treatment should be considered alongside it.
Contact a clinician promptly if symptoms are returning. Seeking support early may provide more options than waiting until daily functioning has become seriously affected.
If you are changing providers, ask for copies of relevant records from your original TMS course. These may include the treatment protocol used, the number of sessions completed, symptom measures, side effects and discharge summary. This information can help a new clinician understand what was previously helpful.
Combining TMS with ongoing care
TMS is often provided alongside other depression treatments rather than replacing all of them. Some patients continue antidepressant medication, while others work with their prescriber on changes to medication. Do not stop or alter prescribed medication without speaking to the clinician who manages it.
Talking therapy can also remain important after TMS. For some people, improved energy and concentration after treatment make it easier to engage with therapy, rebuild routines or address ongoing stresses.
A longer-term plan may include:
- Regular medication reviews where appropriate
- Continued therapy or counselling
- A manageable sleep and daily routine
- Support for alcohol, drug use or smoking where needed
- Physical health care and treatment for pain or sleep problems
- A crisis and safety plan
- Clear instructions for contacting the TMS clinic if symptoms return
Practical follow-up planning in Indiana
TMS Therapy Indiana currently lists 68 published clinics across the state. Directory listings include clinics in Indianapolis, Richmond, Columbus, Danville, Bloomington, Elkhart, Lafayette, Bedford, Fishers, Connersville, Carmel and Seymour, among other Indiana locations.
When choosing a clinic for an initial course, maintenance care or re-treatment, ask about follow-up before you begin. Travel, work schedules and transport can matter more after the intensive weekday phase of a standard TMS course has ended. A clinic may be convenient for an initial treatment course but less practical for occasional future appointments.
Insurance coverage for maintenance or repeat TMS can differ from coverage for an initial course. In Indiana, plans commonly seen include Anthem Blue Cross and Blue Shield, UnitedHealthcare, Aetna, Cigna, MHS Ambetter, CareSource Indiana, the Healthy Indiana Plan (Medicaid) and Medicare. Coverage rules, clinical criteria and prior authorisation requirements can vary by plan and may change.
Before arranging maintenance or re-treatment, contact both the clinic and your insurer. Ask whether the provider is in network, whether prior authorisation is needed, what records are required and what out-of-pocket costs may apply.
