TMS can provide lasting depression relief, but results vary, so Maryland patients should monitor symptoms and use therapy, medication or maintenance care if needed.
How Long Do TMS Results Last? A Maryland Guide to Follow-Up Care
Transcranial magnetic stimulation (TMS) can reduce depression symptoms for some people, but it is not usually helpful to think of treatment as ending completely after the final appointment. Like other treatments for depression, TMS works best when there is a plan for monitoring symptoms and responding early if they return.
TMS was cleared by the FDA for major depressive disorder in 2008, and for depression with comorbid anxiety in 2021. A standard initial course often involves around 36 weekday sessions over six to nine weeks. What happens afterwards varies. Some people remain well without further TMS for a long time, while others need occasional maintenance sessions or a further course of treatment if symptoms return.
For people in Maryland, follow-up care may involve the TMS clinic, a psychiatrist, GP, therapist, or a combination of these professionals. The aim is to keep track of wellbeing, medicines, therapy and practical supports rather than waiting for a full relapse.
What does it mean for TMS results to last?
A lasting result does not necessarily mean that every symptom disappears permanently. More often, it means that depression has improved significantly and that the improvement is sustained over time.
You may notice that you have more energy, a steadier mood, better sleep, clearer thinking or more ability to manage daily tasks. Some people describe returning to interests, work, relationships or routines that depression had made difficult. Others may still have symptoms, but find they are less intense or less disruptive.
How long improvement lasts is individual. It can be influenced by:
- How severe or longstanding the depression was before treatment
- Whether symptoms fully improved or only partly improved during the initial course
- Previous patterns of relapse
- Ongoing medication and psychological therapy
- Major life stress, illness, bereavement or changes in sleep
- Alcohol or substance use
- Whether there are other mental or physical health conditions requiring support
Your TMS team should discuss what a meaningful response looks like for you. It is useful to identify the signs that tell you you are doing well, as well as the early signs that your depression may be returning.
Relapse can happen, but early action matters
Depression can be recurrent, whether it has been treated with TMS, medication, therapy or a combination of approaches. A return of symptoms after a period of improvement is often called relapse or recurrence. It does not mean that TMS has “failed”, nor does it mean you have done anything wrong.
The first signs can be subtle. They may include sleeping much more or less than usual, withdrawing from people, losing motivation, becoming more irritable, struggling to concentrate or noticing that negative thoughts are becoming more persistent. For some people, anxiety increases first. Others notice physical changes such as fatigue, appetite changes or a loss of routine.
It can help to write down your own early warning signs before finishing the initial course. You might also ask a family member, friend or partner what changes they tend to notice. This provides a clearer plan if your mood begins to worsen.
Contact your usual clinician or TMS provider promptly if symptoms return. It is generally easier to review treatment when difficulties are emerging than when depression has become severe again.
If you are at immediate risk of harming yourself or cannot keep yourself safe, seek urgent help through emergency services or a local crisis service.
Maintenance TMS: planned follow-up sessions
Maintenance TMS refers to sessions given after the initial treatment course, usually to support an improvement and reduce the chance of symptoms returning. There is no single maintenance schedule that suits everyone.
Some people do not have planned maintenance sessions. Instead, they continue with medication, talking therapy or other parts of their care plan and return for review only if symptoms recur. Others may have TMS sessions at intervals agreed with their clinician. The timing, frequency and duration should be based on your clinical history, response to treatment and practical circumstances.
A maintenance plan may be considered when someone has had repeated episodes of depression, has relapsed after earlier treatment, or has found that symptoms tend to return in a recognisable pattern. It may also be discussed if a person responded well to TMS but has limited options with medicines because of side effects or past lack of benefit.
Maintenance treatment is not a guarantee against relapse. It is one possible part of an ongoing depression-care plan. Your clinician should explain the purpose of any proposed schedule, how progress will be measured and when the plan will be reviewed.
Re-treatment when symptoms return
Re-treatment, sometimes called a repeat course, is different from routine maintenance. It generally means returning for a more concentrated series of sessions after a meaningful return of depression symptoms.
A clinician will usually reassess you before recommending another course. They may review:
- Your response to the first TMS course
- How long the improvement lasted
- Current symptoms and their impact on daily life
- Changes in medicines, health conditions or personal circumstances
- Whether another treatment should be started, changed or continued alongside TMS
- Any safety issues, including new seizure risks or implanted medical devices
TMS is generally well tolerated. Scalp discomfort and headache are common side effects, particularly early in treatment. Seizure is rare, but screening and clinical review remain important before an initial or repeat course.
If you previously benefited from TMS, tell the clinician what you remember about the course: which symptoms changed first, when you felt most improved, any side effects, and what follow-up support was in place. This can help them make a more informed recommendation.
Planning follow-up before your final session
It is sensible to discuss follow-up well before the last appointment rather than treating the end of the course as an abrupt finish. Ask your provider who will take responsibility for ongoing monitoring and how you should get back in touch if symptoms return.
A practical follow-up plan might include:
- A check-in appointment after treatment has finished
- Continued appointments with your prescribing clinician, if you take medication
- Ongoing therapy or counselling, where appropriate
- A written list of your early warning signs
- Sleep, activity and routine goals that are realistic for you
- A plan for contacting the clinic if you feel your mood slipping
- Permission to involve a trusted person in recognising changes
It can also be useful to keep brief mood notes for a while after treatment. This need not be complicated. A record of sleep, mood, anxiety, activity and major stresses can show patterns that are hard to spot day to day.
Insurance and practical questions in Maryland
Before arranging maintenance sessions or a repeat course, ask both the clinic and your insurer about the current requirements. Coverage can depend on your diagnosis, previous treatments, clinical documentation, the type of TMS proposed and whether prior authorisation is needed.
Maryland patients may encounter plans administered by CareFirst BlueCross BlueShield, UnitedHealthcare, Aetna, Cigna, Kaiser Permanente Mid-Atlantic, Maryland Medicaid HealthChoice MCOs, Medicare through Novitas Jurisdiction L, or TRICARE East. Benefits and approval rules can differ between plans, even within the same insurer.
Ask whether the clinic is in network, whether follow-up or maintenance care is covered, and what documentation may be required if symptoms return. Do not assume that an initial TMS authorisation automatically applies to later sessions.
