TMS may provide lasting relief from major depression, but results vary; follow-up care helps monitor symptoms, support ongoing treatment, and consider maintenance or retreatment.
How Long Do TMS Results Last? A North Carolina 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 at the end of treatment is: how long will that improvement last?
There is no single answer. Some people remain well for a long time after a standard course of TMS, while others notice symptoms gradually returning and may need further support. The durability of a response can depend on the person’s history of depression, their current stressors, whether they continue other treatments, and how quickly changes in mood are recognised.
TMS is not usually viewed as a one-off cure. It is better understood as one part of a longer-term plan for managing depression. Follow-up care can help you and your clinician protect gains made during treatment, identify early warning signs, and decide whether maintenance sessions or a future re-treatment course may be appropriate.
What happens after a course of TMS?
A standard course of TMS commonly involves about 36 weekday sessions over six to nine weeks. The exact schedule may differ between providers and treatment plans.
At the end of the course, your TMS clinician will usually review your symptoms, functioning and goals. This may include discussing:
- Changes in mood, motivation, sleep and concentration
- Whether anxiety symptoms have changed alongside depression
- Any remaining symptoms that need attention
- Medication and talking-therapy plans
- Follow-up appointments with your psychiatrist, primary care clinician or therapist
- A plan for what to do if symptoms return
TMS was cleared by the FDA for major depressive disorder in 2008, and for depression with comorbid anxiety in 2021. However, treatment decisions remain individual. Your follow-up plan should take account of your diagnosis, medical history and previous experiences with depression treatment.
Understanding durability and relapse
A positive TMS response may last after treatment finishes, but depression can be a recurring condition. A return of symptoms does not necessarily mean that TMS “failed” or that earlier improvements were not real. It may mean that further support is needed at a particular point in your care.
Relapse can look different from person to person. For some, symptoms return slowly: sleep becomes unsettled, energy falls, or activities start to feel harder. For others, a downturn may be more noticeable after a period of stress, illness, bereavement, changes at work or family pressures.
It can be useful to distinguish between occasional low mood and a more sustained return of depression. Everyone has difficult days. A pattern that persists, worsens, or affects work, relationships, self-care or safety deserves prompt attention.
Possible warning signs include:
- Losing interest in activities that had become enjoyable again
- Withdrawing from friends, family or routine responsibilities
- Sleeping much more or less than usual
- Increasing hopelessness, guilt or irritability
- A marked drop in energy or concentration
- Changes in appetite
- Thoughts of self-harm or suicide
If you have thoughts of harming yourself or feel unable to stay safe, seek urgent help through emergency services or an appropriate crisis service. Do not wait for a routine follow-up appointment.
Maintenance TMS: what it means
Maintenance TMS refers to sessions given after an initial course has finished, with the aim of supporting ongoing wellbeing or responding early to returning symptoms.
There is no universal maintenance schedule that suits everyone. Some people may not need maintenance sessions. Others may discuss occasional sessions, a short series of sessions, or a more structured plan with their clinician. Decisions are generally based on symptom patterns, previous relapses, response to TMS and practical matters such as travel, work and insurance cover.
Maintenance care should be planned rather than assumed. Ask the provider how they decide whether it is appropriate, what signs would lead them to recommend it, and how progress will be reviewed.
It is also important to ask how maintenance TMS is handled by your insurer. Cover can depend on your policy, clinical documentation and whether a treatment is considered medically necessary. A clinic’s insurance team may be able to explain the authorisation process, but they cannot guarantee approval.
Re-treatment if symptoms return
If depression returns after a period of improvement, a clinician may discuss another course of TMS. This is sometimes called re-treatment or a repeat course.
A re-treatment plan is not necessarily identical to your first course. Your clinician may review what helped previously, how long the benefit lasted, whether medicines or therapy have changed, and whether there are new health concerns. They may also consider whether another treatment approach is more suitable.
Contact your treating clinician early if you notice symptoms building. Waiting until depression becomes severe can make day-to-day life harder and may delay access to care. Early review gives you more options, whether that involves therapy, medication adjustments, support for sleep and routine, maintenance sessions or a repeat TMS course.
TMS is generally well tolerated, though scalp discomfort and headache are common side effects. Seizure is rare. If you are considering further TMS, discuss any changes in your health, medicines or seizure risk with the clinical team.
Building a practical follow-up plan
Before your final TMS session, ask for a clear written or verbal plan. Knowing who to contact and when can reduce uncertainty if symptoms change later.
A useful plan may cover:
- Your next appointment with the clinician managing your depression
- Whether you will continue medication, therapy or both
- Whether maintenance TMS is being considered
- Your personal early warning signs
- Who should be contacted if symptoms return
- What to do outside normal clinic hours
- Crisis contacts and safety planning where needed
- How insurance authorisation would work for future TMS care
It can help to involve a trusted family member or friend, particularly if they have noticed changes in your mood in the past. They may be able to spot early signs that are harder to recognise yourself.
Keeping a simple record of sleep, mood, anxiety, activity and medication changes can also be useful. It does not need to be complicated. The purpose is to help you and your clinician see patterns over time.
Continuing care beyond TMS
For many people, the period after TMS is a time to strengthen routines that support recovery. This might include regular sleep and meals, manageable activity, ongoing counselling, social connection and a plan for handling stress. These steps do not replace clinical treatment, but they can form part of a wider relapse-prevention approach.
Do not stop prescribed antidepressants or other mental health medicines without discussing this with the clinician who prescribes them. Some people continue medication after TMS, while others may have a different plan. Changes should be made carefully and with medical guidance.
If you are working with more than one provider, such as a TMS clinic, psychiatrist, therapist and primary care clinician, ask how information will be shared. Clear communication can prevent gaps in care after the treatment course ends.
