TMS benefits vary over time; follow-up care helps monitor relapse, and some patients may need additional treatment alongside medication, therapy and lifestyle support.
How Long Do TMS Results Last? A Mississippi Guide to Follow-Up Care
For many people considering transcranial magnetic stimulation (TMS), an important question is what happens after the treatment course ends. TMS is not usually thought of as a treatment that requires daily sessions indefinitely. Instead, it is commonly delivered as an initial course, followed by monitoring and, for some people, further treatment if symptoms return.
TMS was cleared by the FDA for major depressive disorder in 2008, and for depression with comorbid anxiety in 2021. A standard course often involves around 36 weekday sessions over six to nine weeks. The aim is to reduce depressive symptoms and help a person regain day-to-day functioning, but the length of benefit varies between individuals.
Planning follow-up before the final session can make it easier to recognise changes early and decide what support may be helpful.
How durable are TMS results?
Some people continue to feel well after completing TMS without needing further sessions for a long time. Others notice symptoms gradually returning and may need additional support sooner. There is no single timetable that applies to everyone.
How long a response lasts can be influenced by several factors, including:
- How severe and longstanding depression was before treatment
- Whether symptoms fully improved or partly improved during the initial course
- Previous patterns of relapse and recovery
- Ongoing medication, talking therapy or other mental health care
- Stressful life events, sleep disruption, substance use, physical illness or changes in routine
- Whether a person has related conditions, such as anxiety
It can be useful to think of TMS as one part of a longer depression care plan. Even when treatment has worked well, follow-up remains important. Depression can be recurrent, and a return of symptoms does not necessarily mean that TMS has stopped working or that the initial treatment was unsuccessful.
What does relapse mean?
Relapse generally means that depressive symptoms return after a period of improvement. The signs may be similar to those experienced before TMS, although they can also be less intense at first.
Possible early warning signs include:
- Lower mood or increased tearfulness
- Loss of interest in activities
- Withdrawing from friends, family or work
- Changes in sleep, appetite or energy
- Difficulty concentrating or making decisions
- Greater anxiety, irritability or hopelessness
- Thoughts of self-harm or suicide
It may help to write down your own early warning signs while you are feeling better. Family members or trusted friends can sometimes notice changes before the person experiencing depression does, so you may also wish to discuss what they should look out for.
A brief dip in mood does not always mean relapse. Everyone has difficult days, particularly during periods of stress. However, symptoms that are persistent, worsening or affecting daily life are worth discussing with a treating clinician promptly.
Follow-up after an initial course of TMS
Your TMS provider may arrange a review after the final session, followed by further check-ins over time. The exact format differs between services and individuals. Some people continue regular appointments with a psychiatrist, GP, therapist or other mental health professional alongside their TMS care.
A useful follow-up plan may cover:
- Who to contact if symptoms start to return
- When your next mental health review will take place
- Whether medication will continue, change or be reviewed
- Whether ongoing therapy could be useful
- Practical plans for sleep, work, family responsibilities and stress
- What to do if you miss a planned appointment
- When maintenance TMS or a new course might be considered
Keep a record of the clinic’s contact details and ask whether there is a preferred way to get in touch between appointments. If you move within Mississippi, you may need to transfer records or find a provider closer to home.
TMS Therapy Mississippi currently lists 21 clinics. Directory listings are available in Bay St. Louis, Hattiesburg, Gulfport, Tupelo, Southaven, Pascagoula, Columbus, Ocean Springs, Ridgeland and Biloxi. Availability, referral requirements and follow-up arrangements can differ by clinic, so it is sensible to ask about these matters before beginning treatment.
Maintenance TMS: what does it involve?
Maintenance TMS refers to sessions given after the initial treatment course, with the intention of helping to sustain improvement or respond to early symptom changes. It is not the same as the standard weekday course of treatment.
There is no single maintenance schedule that is right for everybody. A clinician may recommend occasional sessions, a short series of sessions if symptoms return, or monitoring without planned TMS unless there is a clear change in mood. The decision should be based on your treatment response, history of depression, preferences and access to care.
Ask a clinic whether it offers maintenance treatment and how it decides when it is appropriate. Useful questions include:
- Do you provide maintenance or follow-up TMS after the initial course?
- Is maintenance planned in advance, or only offered if symptoms return?
- Would I see the same clinician for review?
- How would you assess whether I need more sessions?
- What happens if I need support urgently?
- Can you coordinate with my psychiatrist, GP or therapist?
Maintenance treatment may not be necessary for everyone. It is also important not to assume that it will be covered by insurance simply because an initial course was approved.
Re-treatment if depression returns
A new course, sometimes called re-treatment, may be considered when depression returns after an earlier helpful course of TMS. The approach can vary. Some people may have a shorter set of sessions targeted at returning symptoms, while others may be advised to repeat a more complete course.
The clinician will normally review what happened during the first treatment: how much symptoms improved, how long the benefit lasted, whether there were medication changes, and whether any new health concerns have arisen. They may also reassess whether TMS remains the most appropriate option.
TMS is generally well tolerated. Scalp discomfort and headache are common side effects, particularly during treatment. Seizure is rare, but it remains an important risk to discuss with the treating team, especially if there have been changes in medicines or medical history since the original course.
If you had a good response before, tell a future provider about it and request that relevant records are shared where possible. Details such as your treatment protocol, number of sessions, side effects and symptom changes can help with planning.
Insurance and practical preparation in Mississippi
Coverage for follow-up, maintenance sessions and re-treatment can be different from coverage for an initial TMS course. Insurers may have their own requirements for diagnosis, clinical review, prior treatment history and authorisation. A clinic’s billing team may be able to explain its process, but it is still wise to contact your insurer directly.
Insurance carriers commonly seen in Mississippi include Blue Cross and Blue Shield of Mississippi, UnitedHealthcare, Aetna, Cigna, Humana, Ambetter of Magnolia, Mississippi Medicaid and Medicare. Coverage depends on your individual plan and clinical circumstances.
Before agreeing to further TMS, consider asking:
- Is prior authorisation required?
- Is maintenance TMS covered under my plan?
- Is re-treatment assessed differently from my first course?
- Which parts of treatment may involve out-of-pocket costs?
- Do I need a new referral or psychiatric assessment?
- Are there limits on where I can receive treatment?
Practical planning matters too. TMS appointments can require travel and time away from work, study or caring responsibilities. If you live some distance from the clinic, discuss how a maintenance or re-treatment plan could fit your routine.
