TMS benefits for depression can last for varying periods, and Wisconsin patients are advised to plan follow-up care, monitor relapse signs and continue supports.
How Long Do TMS Results Last? A Wisconsin Guide to Follow-Up Care
Transcranial magnetic stimulation (TMS) is a non-invasive treatment most often used for major depressive disorder when other approaches have not provided enough relief. It was cleared by the FDA for major depressive disorder in 2008, and for depression with comorbid anxiety in 2021.
A common question after completing treatment is: how long will the improvement last? There is no single answer. Some people continue to feel well for a long time after a standard course, while others notice symptoms returning sooner and may need further support. Follow-up care is therefore an important part of planning TMS, rather than something to consider only after treatment ends.
In Wisconsin, TMS Therapy Wisconsin lists 47 published clinics. Whether you are finishing treatment in Milwaukee, Appleton, Wausau or another area, it is sensible to discuss a written follow-up plan with your treating clinician before your final session.
Understanding durability after TMS
A standard TMS course commonly involves about 36 weekday sessions over six to nine weeks. The aim is usually to reduce depressive symptoms and help a person regain day-to-day functioning. For some people, this may mean remission, where symptoms are minimal or absent. For others, it may mean a meaningful but incomplete improvement.
TMS does not guarantee that depression will not return. Depression is often a recurring condition, and relapse can happen after any treatment, including medication, talking therapies and TMS. The duration of benefit can be influenced by many factors, such as:
- How fully symptoms improved during the initial course
- Previous episodes of depression and their pattern over time
- Ongoing stress, illness, grief, sleep disruption or substance use
- Whether medication or therapy continues after TMS
- Access to practical and social support
- Other mental or physical health conditions
It can be helpful to think of TMS as one part of longer-term depression care. A good response may create a valuable period in which someone can return to routines, strengthen support, continue therapy or make adjustments to medication with their prescriber.
Relapse does not mean TMS failed
If symptoms return, it does not necessarily mean that the original treatment was unsuccessful. Depression can fluctuate, and a relapse may occur despite a strong initial response.
Early warning signs vary between individuals. They may include lower mood, loss of interest, reduced motivation, changes in sleep or appetite, withdrawing from other people, increased anxiety, difficulty concentrating or a return of hopeless thoughts. Some people recognise these changes gradually; others notice a more sudden shift.
Try not to wait until symptoms are severe before contacting a clinician. Discussing changes early may allow your care team to review what is happening and consider appropriate next steps. These may include changes to medication, resuming or increasing therapy, addressing sleep or stress, or discussing further TMS sessions.
If you have thoughts of harming yourself or feel unable to stay safe, seek urgent help through emergency services, a crisis service or your local emergency department.
Maintenance TMS: what it means
Maintenance TMS refers to planned sessions after an initial treatment course has ended. The purpose is generally to help sustain improvement or reduce the chance of symptoms returning.
There is no single maintenance schedule that suits everyone. Some people do not have maintenance sessions and instead attend follow-up appointments to monitor their wellbeing. Others may have TMS sessions at intervals agreed with their clinician. The approach can depend on a person’s symptom history, response to the initial course, treatment preferences and insurance arrangements.
A clinic may suggest maintenance treatment when someone has had repeated episodes of depression, has relapsed after previous treatments, or has responded particularly well to TMS but remains at higher risk of symptoms returning. However, maintenance TMS is not automatically necessary for every person who completes a course.
It is reasonable to ask your provider:
- Whether they offer maintenance TMS
- How they decide who may benefit from it
- What changes in symptoms should prompt a review
- Whether treatment can be arranged promptly if symptoms return
- How maintenance sessions may be covered by your insurance plan
Coverage rules can differ between insurers and individual plans. A recommendation from a clinician does not by itself confirm that sessions will be covered.
Re-treatment after symptoms return
Re-treatment, sometimes called a repeat course or booster treatment, means returning for another period of TMS after depressive symptoms have returned. This differs from a planned maintenance schedule, although the two approaches can overlap.
A repeat course may be considered for someone who benefited from TMS previously and later experiences a recurrence of depression. The clinician will normally reassess symptoms, safety, other treatments and whether TMS remains appropriate. They may also review whether anything has changed since the original course, including medication, health conditions or implanted medical devices.
Do not assume that you must repeat exactly the same plan as before. The treatment team may recommend a similar protocol, an adjusted approach or another form of care depending on your circumstances.
The practical side matters too. Before starting TMS, ask what the clinic’s process is if you need care again later. Questions might include whether a new referral is needed, how long re-assessment may take, and whether your insurer requires prior authorisation.
Planning follow-up before your final session
The end of an initial TMS course should include more than a final symptom questionnaire. It is a useful time to agree what ongoing care will look like.
A follow-up plan may include appointments with the TMS clinician, psychiatrist, GP, therapist or other mental health professional involved in your care. It should be clear who you should contact if symptoms begin to return.
Consider discussing the following before treatment ends:
- Your current symptom level and the changes you have noticed
- Your personal early warning signs of relapse
- Whether you will continue medication, therapy or both
- A plan for sleep, daily structure, activity and stress management
- How often you should check in with your usual mental health provider
- Whether maintenance TMS is being considered
- What would trigger a request for re-assessment or re-treatment
- Crisis contacts and urgent-care options
Keeping a simple record can also help. Some people track mood, sleep, anxiety, energy, work or study attendance, and social activity. This is not a replacement for clinical assessment, but it can make patterns easier to spot and discuss.
Insurance and practical follow-up in Wisconsin
Insurance is an important part of follow-up planning, particularly if maintenance or repeat TMS may be needed. Carriers commonly seen in Wisconsin include Anthem Blue Cross and Blue Shield (Wisconsin), Quartz Health Solutions, Dean Health Plan, Security Health Plan, UnitedHealthcare, Cigna, Aetna and BadgerCare Plus (Wisconsin Medicaid).
Policies may differ on initial TMS treatment, maintenance sessions and re-treatment. Ask both the clinic and your insurer about prior authorisation, medical review requirements, provider network status and your likely out-of-pocket responsibility. Keep notes of any authorisation numbers and the name of the person or department you speak with.
Wisconsin has directory-listed clinics across several communities. Milwaukee has six published listings, while Waukesha, Wauwatosa, Middleton, West Allis, Glendale and Brookfield each have three. Appleton, Racine, Wausau, Kenosha and Mequon also have multiple listed options. Availability, waiting times and follow-up arrangements can vary, so it is worth asking locally rather than assuming all services offer the same ongoing care.
