How Long Do TMS Results Last? A South Carolina Guide to Follow-Up Care

Transcranial magnetic stimulation (TMS) is a non-invasive treatment most commonly used for major depressive disorder. It uses magnetic pulses applied to targeted areas of the scalp while you are awake. A standard course often involves about 36 weekday sessions over six to nine weeks.

A natural question after completing treatment is: how long will the benefits last?

There is no single answer. Some people continue to feel well after a course of TMS, while others notice symptoms returning over time and may need further support. The durability of results can depend on your history of depression, how fully symptoms improved during treatment, ongoing stress, sleep, physical health, medicines and other mental health care.

The aim of follow-up is not to assume that relapse will happen. It is to notice changes early, maintain the progress you have made and agree a clear plan with your prescribing clinician and TMS team.

What does a lasting TMS response mean?

A lasting response does not necessarily mean never feeling low, anxious or stressed again. Depression can fluctuate, and difficult life events can affect anyone’s mood.

Instead, a durable response may include:

• A sustained reduction in depressive symptoms
• Better daily functioning at home, work or school
• Improved sleep, concentration or motivation
• More ability to use coping strategies and keep routines
• Fewer or less severe depressive episodes

Some people experience a substantial improvement but still have symptoms that need ongoing care. Others may reach remission, meaning their symptoms are minimal or no longer meet the usual threshold for a depressive episode. Both outcomes can be meaningful.

TMS is FDA-cleared for major depressive disorder, with clearance first granted in 2008. It was also cleared in 2021 for depression with comorbid anxiety. Your own diagnosis, treatment history and goals should guide discussions about whether TMS is suitable and what follow-up may look like.

Why symptoms can return

Depression is often a recurring condition. TMS can be an important part of treatment, but it does not remove every factor that contributes to future episodes.

Symptoms may return for reasons such as:

• A previous pattern of recurrent depression
• Stopping or changing prescribed medicines without clinical guidance
• Major stress at work, home or in caring responsibilities
• Bereavement, relationship difficulties or financial pressure
• Disrupted sleep, substance use or changes in physical health
• Loss of regular therapy, social connection or healthy routines

A return of symptoms does not mean that TMS “failed” or that you have done something wrong. It may mean your treatment plan needs adjusting. Early contact with your clinical team can be helpful, rather than waiting until symptoms become severe.

Maintenance TMS: what it means

Maintenance TMS refers to sessions given after the initial treatment course to help support ongoing improvement. There is not one maintenance schedule that suits everyone.

Some people may not need maintenance sessions at all after completing an acute course. Others may discuss occasional sessions, a short series of sessions during a period of worsening symptoms, or a planned maintenance approach based on their previous history. The decision should be individual and reviewed over time.

Your clinician may consider questions such as:

• How severe and frequent were past depressive episodes?
• How much did symptoms improve with the initial TMS course?
• Have you previously relapsed after other treatments?
• Are you continuing medication, talking therapy or both?
• Are there new stressors or warning signs?
• What practical and financial arrangements are realistic for you?

Maintenance care can also mean maintenance of the wider treatment plan: keeping medication reviews, continuing therapy where appropriate, protecting sleep and maintaining contact with supportive people.

Re-treatment when depression returns

If symptoms return after an earlier positive response, some people may be considered for another course of TMS. This is often called re-treatment or a repeat course.

A repeat course is not automatically the right answer for every person. A clinician will usually reassess your current symptoms, safety, diagnosis, medicine changes and other possible contributors, including physical health concerns. They may also ask how long the earlier benefit lasted and whether your treatment circumstances have changed.

It is useful to contact your clinician when symptoms first begin to build, rather than waiting for a full relapse. Warning signs can be subtle. They may include withdrawing from others, missing work or appointments, sleeping much more or less than usual, losing interest in activities, feeling persistently hopeless, or finding everyday tasks harder.

If you have thoughts of harming yourself, feel unable to stay safe or are in immediate danger, seek urgent help through emergency services or an appropriate crisis service. TMS follow-up is important, but urgent mental health needs require immediate assessment.

Planning follow-up before the final session

A good follow-up plan should ideally be discussed before you finish your original course of TMS. Ask who will be responsible for each part of your care: the TMS provider, psychiatrist, primary care clinician, therapist or another prescriber.

Consider writing down a plan that covers:

• Your next review appointment and who to contact between appointments
• Current medicines, doses and who manages prescriptions
• Whether you will continue counselling or psychotherapy
• Your personal early warning signs of depression
• What steps to take if symptoms begin to return
• Whether maintenance TMS or re-treatment may be considered
• A crisis and safety plan, if relevant
• Any practical barriers, such as transport, work schedules or caring duties

A simple symptom diary can be useful in the months after treatment. You do not need to record every emotion. A brief weekly note on mood, sleep, energy, anxiety, activity and functioning can make gradual changes easier to spot.

It can also help to involve a trusted family member or friend, if you feel comfortable doing so. They may notice changes in your routine or mood before you do.

Questions to ask your South Carolina TMS provider

Before completing treatment, you may wish to ask:

• How will we measure whether my improvement is continuing?
• When should my first follow-up review take place?
• Which symptoms should prompt me to call the clinic?
• Do you offer maintenance TMS or repeat courses where clinically appropriate?
• If I move or my circumstances change, how will my care be transferred?
• How does your clinic coordinate with my psychiatrist, GP or therapist?
• What documentation will I receive about my treatment course?
• Can you help me understand coverage requirements if further TMS is recommended?

TMS is generally well tolerated. Scalp discomfort and headache are among the more common side effects. Seizure is rare, but your clinician should review your health history and any changes in medicines or medical conditions before treatment or re-treatment.
