TMS can provide lasting depression relief, but benefits vary and symptoms may return, so follow-up plans and ongoing support can help maintain improvement.
How long can TMS results last?
Transcranial magnetic stimulation (TMS) is usually given as a course of weekday treatment sessions over several weeks. For many people treated for depression, improvement can continue after the final session as the benefits of treatment settle in.
How long a response lasts varies considerably. Some people remain well for a long period after one course. Others notice symptoms gradually returning and may need additional support, changes to their wider treatment plan, or another course of TMS.
TMS is not generally viewed as a permanent cure for depression. Depression can be a recurring condition, and a return of symptoms does not necessarily mean that TMS “failed”. It may reflect the natural course of the illness, changes in stress, sleep, physical health, medication, substance use, or other factors affecting mental wellbeing.
A useful aim after treatment is to have a clear follow-up plan rather than waiting until symptoms become severe again.
What does “response” mean after TMS?
Clinicians may use several terms when discussing outcomes after TMS:
- Response usually means a meaningful reduction in depression symptoms.
- Remission generally means that symptoms have reduced to a level where they are minimal or no longer meet the threshold for a depressive episode.
- Relapse means symptoms return after a period of improvement or remission.
- Recurrence can refer to a new depressive episode after a longer period of wellness.
These terms can sound technical, but the practical question is often simpler: are you able to function more like yourself, and are symptoms remaining manageable over time?
Follow-up may include discussion of mood, anxiety, sleep, energy, concentration, work or study, relationships and daily routines. If you have had thoughts of self-harm in the past, ongoing assessment of safety should also be part of your care plan.
Why results can differ from person to person
There is no reliable way to predict exactly how long TMS benefits will last for an individual. Several factors may influence durability, including:
- Whether symptoms improved partially or reached remission
- Previous episodes of depression and how often they have returned
- Ongoing medication and whether it remains helpful
- Access to talking therapy or other mental health support
- Major life stress, bereavement, trauma or relationship difficulties
- Sleep problems, alcohol or drug use, and physical health conditions
- Whether anxiety, bipolar disorder, obsessive-compulsive symptoms or other conditions are also present
TMS was cleared by the FDA for major depressive disorder in 2008, and for depression with comorbid anxiety in 2021. However, treatment decisions and follow-up arrangements should still be individualised. A person receiving TMS for depression with significant anxiety may need monitoring for both sets of symptoms, rather than focusing on mood alone.
What happens after the final TMS session?
The end of a standard TMS course does not have to mean the end of contact with the treating team. Before discharge, ask what follow-up is included and who will take responsibility for ongoing mental health care.
A follow-up plan may cover:
- A review shortly after treatment finishes
- How and when to contact the clinic if symptoms return
- Continued appointments with a psychiatrist, GP, therapist or other prescriber
- Medication plans, including any changes that should be avoided without medical advice
- Therapy, peer support, or practical support where needed
- Early warning signs that suggest depression may be returning
- What would make maintenance TMS or re-treatment appropriate
It can be helpful to write down your personal early warning signs. These might include disrupted sleep, withdrawing from friends or family, reduced motivation, increasing irritability, a return of hopeless thoughts, or finding ordinary tasks harder than usual. Family members or trusted friends may spot changes before you do, so consider sharing the plan with someone you trust.
Maintenance TMS: what is it?
Maintenance TMS means occasional sessions after the initial treatment course, intended to help sustain improvement or respond early to returning symptoms. It is not the same as a full acute course of daily weekday sessions.
There is no single maintenance schedule that suits everyone. Some people may have planned sessions at intervals agreed with their clinician. Others do not have scheduled maintenance treatment but return if symptoms begin to reappear. Some people may not need further TMS after their first course.
The evidence and clinical practice around maintenance approaches continue to develop. Availability can also differ between clinics, and insurance cover may be more limited or require specific clinical justification. Ask a prospective clinic how it approaches follow-up rather than assuming that maintenance sessions will automatically be offered or covered.
Questions worth asking include:
- Does the clinic offer planned maintenance TMS, symptom-triggered sessions, or both?
- Who decides whether further treatment is clinically appropriate?
- How will progress be measured after the acute course?
- What happens if symptoms return outside the clinic’s usual appointment times?
- Will my referring clinician receive a treatment summary?
- How does the clinic handle insurance authorisation for further sessions?
Re-treatment if symptoms return
A new course of TMS may be considered if depression returns after a previous helpful course. This is often called re-treatment or a repeat course. It is not unusual for clinicians to review TMS again when someone previously responded and then experienced a relapse.
Before re-treatment begins, a clinician should reassess your current symptoms and overall situation. The review may include whether the symptoms are similar to the earlier episode, whether medication or therapy has changed, whether there are new health concerns, and whether another form of support should be considered alongside TMS.
Do not wait until you are in crisis to make contact. If you notice a gradual return of depression, speaking to your treating clinician early may give more options for managing symptoms.
If you are at immediate risk of harming yourself or someone else, seek urgent help through emergency services or a local crisis service rather than waiting for a routine TMS appointment.
Planning for follow-up care in Michigan
Michigan residents may receive TMS near home, near work, or through a clinic that is convenient for regular travel. TMS Therapy Michigan currently lists 55 published clinics across the state, including listings in Grand Rapids, Lansing, Troy, Southfield, Detroit, Grandville, Flint, St. Clair Shores, Brighton, Okemos, East Lansing and Bloomfield Hills.
When comparing clinics, location matters not only during the initial course but afterwards as well. If maintenance sessions or re-treatment become part of your plan, consider how manageable travel will be during work, family responsibilities, winter weather and periods when depression makes leaving home more difficult.
It is also sensible to ask about continuity of care. A clinic may provide TMS treatment while your GP, psychiatrist or therapist remains responsible for wider mental health care. Clear communication between professionals can reduce the risk of medication changes, symptom concerns or relapse warning signs being missed.
Insurance arrangements can affect follow-up decisions. Carriers commonly seen in Michigan include Blue Cross Blue Shield of Michigan, Priority Health, Molina Healthcare of Michigan, McLaren Health Plan, UnitedHealthcare, Aetna, Michigan Medicaid and Medicare. Cover for an initial TMS course does not automatically confirm cover for maintenance sessions or a later repeat course. Check directly with both the insurer and clinic, and ask what prior authorisation or clinical documentation may be required.
A practical checklist after TMS
Before your final sessions, try to leave with answers to the following:
- Who should I contact if my mood worsens?
- When is my next mental health review?
- Which symptoms should prompt an earlier appointment?
- Should I continue medication or therapy, and who will review this?
- Is maintenance TMS an option for me?
- If I relapse, could I be assessed for another TMS course?
- What insurance cover should I confirm before arranging further sessions?
- Can the clinic send a summary to my usual doctor or therapist?
