TMS for Long-Term Depression Management: What to Expect After Treatment

Transcranial Magnetic Stimulation (TMS) has become a life-changing treatment for people living with treatment-resistant depression. For many, TMS offers what other interventions haven’t: meaningful, measurable relief from depressive symptoms — often without the side effects of medication.

But one of the most common questions patients and families ask is: “What happens after the TMS course ends?”

In this blog, we’ll walk through what to expect after completing TMS, how long the results last, and what options are available if symptoms return — so you feel confident about your long-term depression management plan.

How TMS Works: A Quick Recap

TMS is an FDA-approved, non-invasive treatment that uses magnetic pulses to stimulate specific areas of the brain involved in mood regulation — most commonly, the left dorsolateral prefrontal cortex (DLPFC).

Patients typically undergo a course of daily treatments (5 days/week) for 6 to 8 weeks. Over time, these sessions help rewire neural pathways involved in depression.

But once the initial course is completed, what happens next?

Long-Term TMS Results: What the Research Shows

The good news: TMS doesn't just provide short-term symptom relief — it has strong data supporting durability of benefit for many patients.

A systematic review of preservation TMS (i.e. continuation/maintenance TMS) supports using TMS to sustain clinical response after acute treatment.”

📊 What the Studies Say:

• A 2021 review found that 50–60% of patients maintain remission or significant improvement 12 months after treatment

• In one 2023 follow-up study, two-thirds of responders did not require additional TMS treatments in the year following initial therapy

• Maintenance therapy and booster sessions may reduce risk of depression relapse even further

It’s important to note that individual results vary — and long-term outcomes often depend on compliance with follow-up care, therapy, lifestyle changes, and medical management.

What Is TMS Maintenance Therapy?

TMS maintenance therapy involves periodic follow-up treatments after the initial course — even if a patient is still feeling well.

The idea is similar to how some people continue medication or therapy to prevent relapse, not just to treat current symptoms.

🔄 Two Main Approaches:

1. Scheduled Maintenance:

   • Pre-planned “booster” sessions (e.g. once every 4–6 weeks)

   • Ideal for patients with a strong response who want to protect long-term gains

2. As-Needed Maintenance:

   • Treatment only when symptoms begin to return

   • Ideal for patients who can reliably track mood and triggers

At CPS, we work with each patient to develop a customized follow-up plan, based on clinical response, history of relapse, and individual preferences.

What Are the Signs of a Possible Relapse?

Depression can return — sometimes subtly at first. Watch for:

• Trouble sleeping

• Loss of interest in activities

• Persistent low mood or irritability

• Fatigue or low motivation

• Changes in appetite or weight

• Feelings of worthlessness

If these signs persist for more than 10–14 days, it’s time to check in with your provider. Early intervention can often reverse the slide before it becomes a full relapse.

What Happens If Depression Comes Back?

It’s important to understand: a return of symptoms does not mean TMS failed. Depression is a chronic condition for many people — and like other long-term illnesses (diabetes, hypertension), ongoing care is often needed.

Research suggests relapse risk is highest around five months post‑treatment, making early follow-up meaningful.

Options include:

• TMS booster sessions: A short series (often 5–10 treatments) may restore symptom control

• Adjusting medication: Sometimes medications are more effective after TMS primes the brain

• Psychotherapy: Talk therapy helps reinforce behavioral and cognitive skills to manage mood

• Lifestyle changes: Exercise, sleep hygiene, and social connection are powerful maintenance tools

At CPS, we take a whole-person approach — looking at physical, psychological, and social factors that may impact long-term outcomes.

FAQs About Life After TMS

Q: How long do the effects of TMS last?

A: For most patients, symptom relief lasts 6–12 months or longer, especially with follow-up care.

Q: Will I need TMS forever?

A: Not usually. Some patients may do a full course just once. Others may benefit from booster sessions every few months, depending on how their depression behaves over time.

Q: Does insurance cover maintenance or booster TMS?

A: Some plans do, especially if symptoms return. Most commonly, insurance will cover/recommend a full course of treatment if depression symptoms return. Our team helps you navigate coverage and pre-authorization.
