Does TMS Work? An Honest Guide to Response and Remission in Maryland

Does TMS work for depression?

Transcranial magnetic stimulation, usually shortened to TMS, can help some people with depression, particularly when antidepressant medicines have not provided enough benefit or have caused difficult side effects. It is not a guaranteed treatment, and it does not work in the same way for everyone.

TMS uses magnetic pulses placed against the scalp to stimulate areas of the brain involved in mood regulation. It is non-invasive: there is no surgery, no implanted device and no need for general anaesthetic. A person is awake during treatment and can generally return to usual activities afterwards.

The US Food and Drug Administration first cleared TMS for major depressive disorder in 2008. It later cleared TMS for depression with comorbid anxiety in 2021. These clearances reflect evidence that TMS can be an appropriate treatment option for some patients, but they do not mean every person will respond.

For people in Maryland who are considering treatment, it can be useful to understand how clinicians and research studies describe results. The two terms most often used are response and remission.

What does “response” mean?

In TMS research, a response usually means that a person’s depression symptoms have reduced substantially from where they started treatment. It is commonly measured using a recognised depression questionnaire completed before and during treatment.

A response does not necessarily mean that all symptoms have gone away. Someone may still experience low mood, poor sleep, reduced motivation or anxiety, but at a lower intensity or less often than before. They may find it easier to work, study, maintain relationships or manage day-to-day responsibilities.

Response is an important outcome because depression can improve in meaningful steps. A person does not need to feel completely symptom-free for treatment to have made a worthwhile difference.

Clinicians will usually look beyond a score on a questionnaire. They may also ask questions such as:

• Is it easier to get out of bed or start the day?
• Have suicidal thoughts reduced, stayed the same or increased?
• Is concentration improving?
• Are you able to take part in activities that depression had interrupted?
• Have sleep, appetite or energy changed?
• Are medicines, therapy or other supports also changing at the same time?

The answer is individual. Two people can have similar questionnaire scores yet describe very different experiences of recovery.

What does “remission” mean?

Remission means that depression symptoms have reduced to a level considered minimal or no longer clinically significant on a rating scale. In everyday terms, it means a person is no longer experiencing an active depressive episode by the measure being used.

Remission is generally a stronger result than response. A person can respond without reaching remission, while everyone in remission would usually be considered to have responded.

It is also worth distinguishing remission from a permanent cure. Depression can return after any treatment, including TMS, medication and talking therapy. Some people remain well after a course of TMS, while others may need continuing mental health care, changes to medication, psychotherapy, lifestyle support or, in some cases, further TMS treatment.

A remission result is encouraging, but follow-up care still matters.

What published TMS trials generally report

Published clinical trials and later real-world studies have found that TMS can reduce depression symptoms for a meaningful proportion of people with major depressive disorder. Across studies, some participants achieve response, some reach remission, some notice only modest changes, and some do not improve enough to consider the course successful.

Results vary between studies because the participants, treatment protocols and outcome measures are not always the same. Some trials include people who have tried several antidepressants without enough improvement. Others may include patients earlier in their treatment journey. Studies may use different forms of TMS, different pulse patterns and different methods for judging improvement.

For this reason, it is better to view published findings as an indication of what may be possible rather than a personal prediction.

A clinic should be able to explain how it will measure progress during treatment and what it would do if symptoms do not improve as hoped. This may include reviewing the diagnosis, checking whether the treatment plan is being delivered consistently, considering medication changes with the prescribing clinician, or discussing other treatment options.

Why individual TMS results vary

Depression is not one identical condition. It can involve different symptom patterns, causes and levels of severity. That is one reason outcomes differ from person to person.

Factors that may affect an individual’s experience include:

• Previous treatment history. People seeking TMS have often already tried medicines, therapy or both. The number and type of previous treatments, and how well they were tolerated, may be relevant to planning care.
• The nature of the depression. Depression can occur alongside anxiety, trauma-related symptoms, substance use, chronic pain, sleep problems and other health conditions. These factors may need attention alongside TMS.
• The treatment protocol. TMS is not a single uniform procedure. A clinician may recommend a particular approach based on the diagnosis, symptoms and the equipment available.
• Attendance and completion. A standard TMS course is often around 36 weekday sessions delivered over six to nine weeks. Keeping appointments as consistently as possible helps a clinic assess the treatment fairly and deliver the planned course.
• Other treatment and support. TMS may be used alongside antidepressant medication, counselling or psychotherapy. A person’s wider support network, housing, work pressures and physical health can also affect recovery.
• Time. Some people notice change during the course, while others may not recognise improvement until later. Early changes can be uneven, and a difficult week does not always show that treatment will fail.

No clinic can honestly promise remission. A careful assessment should include a discussion of possible benefits, limitations, alternatives and practical commitments.

What the treatment process is usually like

Before starting TMS, a clinician will normally review your mental health history, current symptoms, medicines and any reasons the treatment may not be suitable. It is important to mention any history of seizures, neurological conditions, implanted medical devices or metal in or near the head.

During a session, a magnetic coil rests against the scalp. The treatment can feel like tapping or knocking on the head. Sessions are commonly brief, although the exact duration depends on the protocol.

The most common side effects are scalp discomfort and headache. These are usually manageable and may lessen as treatment continues. Seizure is a rare risk. A clinic should discuss safety screening and side effects before treatment begins.

TMS is generally delivered on weekdays over several weeks, so travel and scheduling are practical considerations. Maryland residents may want to ask about appointment times, parking, public transport access and whether a clinic can accommodate work or caring responsibilities.

Questions to ask a Maryland TMS clinic

Maryland has 100 published clinics listed in the TMS Therapy Maryland directory. Listings include clinics in Bethesda, Columbia, Towson, Annapolis, Rockville, Baltimore, Easton, Crofton, Arnold, Frederick, California and Bowie.

When comparing options, useful questions include:

• What diagnosis and symptoms is TMS being recommended for?
• How will you define response and remission in my case?
• Which rating scale or other measures will you use to track progress?
• What course length and attendance schedule do you recommend?
• Who will oversee my treatment and communicate with my psychiatrist or GP?
• What happens if I do not improve during the expected treatment period?
• Are medication and therapy plans expected to continue?
• What are the likely out-of-pocket costs, and can you check my cover before treatment starts?

Insurance arrangements vary by plan and provider. Carriers commonly seen in Maryland include CareFirst BlueCross BlueShield, UnitedHealthcare, Aetna, Cigna, Kaiser Permanente Mid-Atlantic, Maryland Medicaid HealthChoice MCOs, Medicare through Novitas Jurisdiction L, and TRICARE East. Coverage decisions can depend on diagnosis, previous treatments, referral requirements and prior authorisation, so it is sensible to confirm details directly with both the insurer and clinic.

A balanced way to think about outcomes

TMS can be a reasonable option for people whose depression has remained difficult despite other care. Research supports its use, but the outcome cannot be known in advance for any one person.

The most helpful expectation is often neither certainty nor pessimism: TMS may lead to a substantial reduction in symptoms, possibly remission, but it may also produce partial improvement or no adequate benefit. A thorough assessment, realistic discussion and regular review of progress can help you decide whether it is right for you.
