How Long Do TMS Results Last? A New York Guide to Follow-Up Care

How Long Do TMS Results Last?

Transcranial magnetic stimulation (TMS) is used most often for major depressive disorder. It involves placing a magnetic coil against the scalp to stimulate targeted areas of the brain associated with mood regulation. In the United States, TMS was cleared by the FDA for major depressive disorder in 2008, and for depression with comorbid anxiety in 2021.

A common question after completing treatment is how long the benefit will last. There is no single answer. Some people continue to feel better for a long period after their initial course, while others notice symptoms gradually returning and may need further support.

It can help to think of TMS as one part of an ongoing depression-care plan rather than a treatment that always ends follow-up needs. Your response, previous pattern of depression, medicines, talking therapy, physical health, stress levels and access to continuing care can all affect what happens after treatment.

A standard TMS course is often around 36 weekday sessions over six to nine weeks. At the end of that course, your clinician should discuss how your symptoms have changed and what follow-up will look like.

What does a lasting response mean?

A response to TMS generally means that depressive symptoms have improved meaningfully. Remission is a related but different term: it usually means symptoms have reduced to a minimal level. Neither term guarantees that depression will never return.

Depression can be recurrent, even after a good response to treatment. A person may remain well for some time and later experience a return of low mood, loss of interest, sleep changes, fatigue, anxiety or difficulty concentrating. This is often called relapse when it happens after improvement or remission.

The durability of TMS results varies considerably between individuals. It is not possible to predict precisely at the start of treatment whether someone will require maintenance sessions or a future repeat course. However, the pattern of a person’s past depressive episodes can provide useful context. Someone who has experienced repeated episodes or who has previously needed ongoing treatment may wish to plan more regular monitoring after TMS.

It is also worth remembering that recovery is not always all-or-nothing. Symptoms may fluctuate without meaning that TMS has stopped working altogether. Early discussion with a clinician can help distinguish a temporary difficult period from a more sustained return of depression.

Relapse does not mean treatment has failed

A return of symptoms can feel discouraging, particularly after the time and effort involved in a course of weekday appointments. But relapse is a recognised part of managing a condition that can be long term or recurrent. It does not automatically mean that the original TMS course was ineffective.

If symptoms begin to return, your treating clinician may review several areas:

• the timing and severity of the changes
• sleep, work, family or other recent pressures
• current medicines and any recent changes
• alcohol or substance use, where relevant
• physical health concerns that may affect mood
• whether talking therapy or other supports are in place
• whether TMS maintenance or re-treatment may be appropriate.

It is generally easier to make a plan when changes are noticed early. Keeping a simple record of mood, sleep, energy, anxiety and daily functioning can be useful between appointments. Some people also ask a family member, friend or therapist to help identify early warning signs, particularly if they tend to minimise symptoms when depression returns.

Maintenance TMS: ongoing sessions after the initial course

Maintenance TMS refers to sessions provided after an initial treatment course, with the aim of helping sustain improvement or reducing the chance of symptoms returning. There is no single maintenance schedule that suits everyone.

For some people, a clinician may suggest occasional sessions that are spaced out over time. For others, the plan may involve no scheduled maintenance, but a clear route back to the clinic if symptoms recur. The decision is individual and may depend on how well someone responded, how stable that improvement has been, their history of relapse and the practicalities of attending appointments.

Maintenance arrangements can also be affected by insurance rules and prior authorisation requirements. Coverage is not the same across plans, and approval for an initial course does not necessarily mean that maintenance sessions will be covered in the same way. Before agreeing to ongoing treatment, ask the clinic and your insurer what documentation may be required, what your plan considers medically necessary and what out-of-pocket costs could apply.

In New York, patients may encounter plans including Empire BlueCross BlueShield, EmblemHealth / HIP, Fidelis Care, Aetna, Cigna, UnitedHealthcare / Oxford, NY Medicaid Managed Care and Medicare, including Advantage plans. Individual benefits can differ even within the same insurer, so it is important to check your own policy rather than relying on general information.

Re-treatment when symptoms return

Re-treatment, sometimes called a repeat course or “booster” treatment, is different from a maintenance plan. It usually means returning for a further series of TMS sessions after a more definite return of depressive symptoms.

A clinician will normally reassess you before recommending re-treatment. They may review how you responded to the first course, how long the improvement lasted, whether there have been changes in medicines or health, and whether TMS remains suitable for you.

The details of a repeat course can vary. It may not necessarily be identical to the original plan. Your clinician should explain the proposed schedule, goals, expected monitoring and how progress will be assessed.

If you have previously had a good response to TMS, make sure you keep a record of where and when you were treated, the protocol used where available, and any information about your symptom improvement. This can be helpful if you later move, change insurer or seek treatment at another New York clinic.

Planning follow-up before your last TMS session

The final week of an initial TMS course is a useful time to put a follow-up plan in writing. Do not wait until symptoms have become severe to work out whom to contact.

A practical plan may include:

• a follow-up appointment with the TMS prescriber or referring mental health clinician
• regular reviews with your psychiatrist, GP or other clinician involved in depression care
• a plan for medicines, including who will manage any changes
• continuing psychotherapy, if this is part of your care
• a description of your personal early warning signs
• contact details for the clinic and instructions for requesting review
• an agreement about when maintenance or re-treatment would be considered
• urgent support contacts for a mental health crisis.

Ask whether the clinic measures symptoms using questionnaires before, during and after treatment. Consistent symptom tracking can make it easier to identify gradual changes that might otherwise be missed.

You may also want to discuss practical issues specific to your routine. In New York, travel time, work arrangements, caring responsibilities and appointment availability can affect whether a maintenance plan is realistic. A plan that cannot be followed is less useful than one that fits your circumstances.

Safety and changes after treatment

TMS is generally well tolerated. Common side effects include scalp discomfort and headache, often around the treatment period. Seizure is rare, but your clinic should review relevant medical history and any changes in medicines or health that could affect safety.

Tell your clinician promptly about significant mood changes, new symptoms, medication changes or any concern about side effects. If you experience thoughts of harming yourself or feel unable to stay safe, seek urgent mental health or emergency support rather than waiting for a routine TMS appointment.

Finding follow-up care in New York

Continuity matters, whether you are considering your first course, completing treatment or exploring a repeat course. TMS Therapy New York lists 223 published clinics across the state, including listings in Carmel Hamlet, New York, Mount Kisco, Garden City, Buffalo, Rochester, White Plains, Albany, Park Slope, Yonkers, Syracuse and New Rochelle.

When comparing clinics, ask whether they provide follow-up after the acute course, how they handle symptom recurrence, whether they offer maintenance appointments and how they support insurance verification. It may also be helpful to ask whether the treating clinician can coordinate with your existing psychiatrist, therapist or primary care doctor.
