TMS can reduce depression symptoms for varying periods, with relapse possible, so patients should monitor changes and use follow-up care, therapy, medication or retreatment as needed.
How Long Do TMS Results Last? A Ohio Guide to Follow-Up Care
Transcranial magnetic stimulation (TMS) can help some people with major depressive disorder achieve a meaningful improvement in symptoms. A common question after completing treatment is how long that improvement may last.
There is no single answer. Some people continue to feel well for a long time after their initial course, while others notice symptoms gradually returning and may need further support. The durability of results can depend on the severity and pattern of depression, previous episodes, ongoing medicines or therapy, life circumstances, sleep, substance use, and other health conditions.
TMS is usually given as a course of weekday sessions over several weeks. Once that acute course ends, the focus changes from attending treatment regularly to monitoring wellbeing and having a clear follow-up plan.
What “lasting results” can mean
TMS does not always produce an all-or-nothing outcome. Results may include:
- A substantial reduction in depression symptoms
- A partial improvement, with some symptoms still present
- A period of remission, where symptoms are minimal or absent
- Improvement that is maintained with ongoing mental health care
- Improvement followed by a later return of symptoms
It can be useful to discuss results in practical terms rather than only using a score on a questionnaire. For example, you may notice that you are sleeping more regularly, returning to work or study, reconnecting with others, finding daily tasks easier, or experiencing fewer distressing thoughts.
Your TMS clinician may use symptom scales before, during and after treatment. These can help identify changes that may be easy to miss from day to day. They are also useful as a baseline if symptoms return later.
Relapse is possible, but it is not a failure
Depression can be a recurring condition. Even after a successful response to TMS, some people have another depressive episode in the future. This is often described as relapse when symptoms return after an improvement, or recurrence when a new episode develops after a longer period of wellness.
A return of symptoms does not necessarily mean that TMS “stopped working” or that you did something wrong. It may mean that your depression needs further treatment at that point, just as it might after improvement with medication, talking therapy or another approach.
Early signs can vary from person to person. They may include:
- Sleeping much more or much less than usual
- Loss of interest in activities that had become manageable again
- Increasing fatigue or difficulty concentrating
- Withdrawal from family, friends or responsibilities
- Changes in appetite
- A return of persistent low mood, hopelessness or anxiety
- Thoughts of self-harm or suicide
It can help to write down your own early warning signs before the end of your TMS course. A partner, friend or family member may also notice changes before you do.
If you have thoughts of harming yourself or feel unable to stay safe, seek urgent help through emergency services or a crisis service rather than waiting for a routine TMS appointment.
Maintenance TMS: what it involves
Some people and clinicians consider maintenance TMS after an initial course. This means occasional further sessions intended to support stability or address early symptom changes. Maintenance plans are not identical for everyone.
A clinic may recommend scheduled sessions at gradually wider intervals, while another person may only return if symptoms begin to reappear. In some cases, the plan is based on symptom monitoring rather than a fixed timetable. The right approach depends on your treatment response, history of depression, other treatments and practical circumstances.
Evidence and clinical practice around maintenance TMS continue to develop, and there is no universal maintenance schedule that suits every patient. It is reasonable to ask your treating team:
- Whether they offer maintenance sessions
- How they decide who may benefit from maintenance care
- What signs would prompt a review
- Whether treatment would be planned in advance or arranged as needed
- How they coordinate with your psychiatrist, GP or therapist
- What insurance authorisation may be required
Maintenance TMS should be part of a wider plan, not the only form of follow-up. Continuing medication where appropriate, attending therapy, protecting sleep and maintaining regular contact with your mental health team may all matter.
Re-treatment after symptoms return
If depression symptoms return after a period of improvement, some people may be considered for another course of TMS. This is often called re-treatment or a repeat course.
The decision is individual. Your clinician will usually want to understand when symptoms returned, how severe they are, whether there have been changes in medication or health, and how you responded to the first course. They may also review whether other treatment options should be adjusted alongside TMS.
It is generally better to raise concerns early rather than waiting until symptoms become severe. A prompt review may give you and your clinical team more options. Keep a record of your mood, sleep, anxiety, functioning and any major stressors if you start to feel less well. This information can make the review more useful.
If you are returning to a different clinic, ask for copies of relevant treatment records from your original provider where possible. This may include your treatment summary, response measures, medication list and details of the TMS protocol used.
Planning follow-up before your course ends
A follow-up plan is most helpful when it is discussed before the final TMS session. You should know who to contact, what symptoms to watch for and how other parts of your care will continue.
Consider covering the following points with your TMS team:
- A follow-up appointment after the acute course
- Who will manage antidepressant or other psychiatric medication
- Whether you will continue with counselling or psychotherapy
- Whether maintenance TMS is clinically appropriate for you
- How to contact the clinic if symptoms begin to return
- What to do if you need support outside clinic hours
- Whether your insurer needs approval before maintenance or repeat treatment
- How your GP, psychiatrist and therapist will receive updates
If you take medication, do not stop or alter it simply because you are feeling better after TMS unless the clinician responsible for prescribing it advises you to do so. Likewise, continuing therapy may help you build on improvements in mood, routines and coping skills.
Insurance and practical planning in Ohio
Coverage for TMS, follow-up sessions and repeat treatment can differ between plans. In Ohio, people commonly encounter insurers including Anthem Blue Cross and Blue Shield, Medical Mutual of Ohio, UnitedHealthcare, Aetna, Cigna, Humana, Ohio Medicaid managed care plans and Medicare.
Your cover may depend on your particular plan, diagnosis, prior treatment history, provider network and whether authorisation is needed. Maintenance or re-treatment may be reviewed differently from an initial course. Ask both the clinic and your insurer about eligibility, referrals, authorisation and potential out-of-pocket costs before assuming that follow-up sessions are covered.
Practical access also matters when planning long-term care. TMS Therapy Ohio lists 91 published clinics across the state, including listings in Cincinnati, Mason, Beachwood, Cleveland, Hilliard, Columbus, Sandusky, Youngstown, Akron, Dublin, Centerville and Maumee. If you may need follow-up care, consider travel time, appointment availability and whether the clinic can coordinate with your existing mental health professionals.
Keeping track of your wellbeing
A simple written plan can make follow-up feel more manageable. It might include your current medicines, helpful routines, warning signs, preferred supports and contact details for your care team.
You do not need to wait for a full relapse to ask for help. If your mood begins to shift, a conversation with your clinician can clarify whether you need closer monitoring, changes to ongoing treatment, further therapy, medication review or consideration of TMS follow-up.
