Your First TMS Appointment in New Hampshire: Mapping, Sensations and What Comes Next

Your First TMS Appointment in New Hampshire: Mapping, Sensations and What Comes Next

Starting transcranial magnetic stimulation (TMS) can feel like a significant step, particularly if you have been living with depression for some time or have tried several other treatments. Your first appointment is usually longer and more detailed than the sessions that follow. It is commonly focused on preparation: confirming that TMS is appropriate for you, finding the treatment position and measuring your motor threshold.

TMS is a non-invasive treatment that uses magnetic pulses to stimulate selected areas of the brain. It was cleared by the FDA for major depressive disorder in 2008, with clearance later extended to depression with comorbid anxiety in 2021.

TMS Therapy New Hampshire lists 29 published clinics across the state. There are directory listings in Manchester, Derry, Nashua, Salem, Dover, Portsmouth, Londonderry, Bedford, Peterborough, Concord and Exeter. Although the details of an appointment can vary between providers, the main stages of first-visit mapping are broadly similar.

Why the first appointment is different

Later TMS appointments are often relatively straightforward. Once your treatment settings have been established, you may check in, sit in the treatment chair, receive the planned session and leave afterwards.

The first visit usually takes more time because the clinical team needs to personalise the treatment setup. They may review your medical history, current medicines and any changes since your initial assessment. It is important to mention any history of seizures, neurological conditions, head injury, implanted medical devices, metal in or near the head, or changes to medicines that could affect seizure risk.

The appointment may include:

• A discussion of the treatment plan and consent process
• A review of practical arrangements, including attendance and missed-session policies
• Positioning you comfortably in the treatment chair
• Identifying a consistent head position for future sessions
• Motor threshold mapping
• The first treatment session, in many cases

Some clinics complete mapping and begin treatment during the same visit. Others may arrange the first treatment session separately. Your provider can tell you what to expect from their schedule.

A standard TMS course commonly involves around 36 weekday sessions over six to nine weeks. The exact number, frequency and protocol depend on your clinical assessment, the type of TMS being used and your provider’s plan.

What motor threshold mapping means

Motor threshold mapping is a measurement used to help set the intensity of your treatment safely and individually. It is not a test of intelligence, strength or how severe your depression is.

During mapping, the clinician places the TMS coil against a specific area of your scalp, often towards the front and side of the head. The coil produces brief magnetic pulses. The team looks for a small, reliable movement in a hand or finger, usually on the opposite side of the body to the stimulated area.

For example, you may be asked to relax one hand while the clinician delivers pulses and watches for a twitch in your thumb, fingers or wrist. The treatment intensity is then based on the lowest level of stimulation that produces a consistent response. This is called your motor threshold.

The motor area used for this measurement is not necessarily the area treated for depression. Mapping helps the clinician determine an appropriate setting, while the treatment coil is positioned over the brain region targeted by your prescribed protocol.

You may hear terms such as “threshold”, “mapping”, “calibration” or “dose”. If the terminology is unclear, it is reasonable to ask the clinician to explain what they are measuring and how it relates to your treatment.

What the sensations can feel like

People experience TMS differently, but most describe the pulses as a repeated tapping, knocking or flicking sensation against the scalp. The machine also makes a clicking sound with each pulse. You will usually be offered ear protection because of the noise.

During motor threshold mapping, the sensations may be felt over the scalp and you may notice the hand or fingers moving briefly. This movement is expected and helps the clinician find the appropriate threshold.

During treatment, you may feel:

• Tapping or pressure on the scalp
• Tightening or brief twitching in facial muscles
• A sensation around the forehead, temple or jaw
• Mild discomfort at the treatment site
• A headache during or after the session

Scalp discomfort and headache are among the more common side effects of TMS. They are often manageable and may become less noticeable as you become used to the sessions. Tell the treatment team promptly if the pulses feel painful, if you develop a persistent headache or if anything feels different from what was explained.

The clinician may be able to adjust the coil position, seating position or the way intensity is increased. In some cases, treatment intensity is gradually raised towards the prescribed level rather than reaching it immediately. This can make the first sessions more tolerable for some people.

TMS does not involve anaesthesia or sedation. You remain awake and able to communicate throughout the appointment. You can normally stop or ask for a pause if you need one.

Preparing for the visit

Your clinic should provide its own instructions before the appointment. It is sensible to follow these closely, particularly where medicines, alcohol, recreational drugs, sleep or caffeine are concerned.

In general, it can help to:

• Arrive with an up-to-date list of medicines and supplements
• Tell the team about any new diagnosis, illness or head injury
• Mention recent changes in sleep, alcohol use or medicines
• Wear comfortable clothing
• Bring glasses or hearing aids if you normally use them, unless the clinic advises otherwise
• Ask in advance whether there is paperwork to complete before arrival

Try not to make sudden changes to prescribed medication without discussing this with the clinician who manages your care. Treatment safety decisions rely on accurate information about your health and medicines.

It may also be useful to plan for the first visit to take longer than a routine session. If you work, care for children or rely on public transport, ask the clinic how much time to allow.

Can you drive after your first TMS appointment?

Many people can drive themselves home after TMS because the treatment does not usually involve sedation and does not normally impair alertness in the way some medicines can. However, whether you should drive after your first appointment is an individual question.

Your clinic may advise you to arrange a lift for the first visit, particularly if you are unsure how you will feel, are prone to headaches, are starting or changing medicines, or have a long journey home. It can also reduce pressure if the initial appointment includes mapping, paperwork and your first treatment session.

Do not drive if you feel unwell, dizzy, unusually tired, distracted by pain or headache, or otherwise not fit to drive safely. Let the clinic know before you leave if you have concerns. They can discuss whether resting for a short time, contacting someone for a lift or making another arrangement is appropriate.

It is also important to follow any specific advice from your TMS provider. Clinic policies can differ, and your wider medical situation may affect the recommendation. If you have a seizure history or another condition that affects driving, discuss this clearly with your treating clinician.

Seizure is a rare side effect of TMS, but it is one reason that careful screening and adherence to the treatment plan matter.

What happens after mapping

Once the mapping process is complete, the team records the settings and positioning needed for future appointments. They may use a headrest, measurements, markings or a positioning system so that the coil can be placed consistently at later visits.

The first few sessions can still involve adjustments. Your motor threshold may be reviewed again during the course of treatment, especially if there are relevant changes in medication, health or treatment response. This is a normal part of safe clinical care, rather than a sign that something has gone wrong.

Your provider should also explain how progress will be monitored. TMS does not usually produce an immediate mood change after a single session. Some people notice changes gradually over the course, while others need a longer period before they and their clinician can judge the effect.

Keep attending as planned where possible, and let the clinic know if you need to miss a session. Regular weekday attendance is generally part of a standard course, so practical planning can be important from the start.

Questions worth asking your clinic

Before leaving your first appointment, you may wish to ask:

• How long will my usual sessions take?
• Will I have the same clinician or technician each time?
• What should I do if I get a headache or scalp discomfort?
• Can I drive after my appointments?
• Who should I contact outside appointment hours if I have a concern?
• How will we review whether treatment is helping?
• What happens if I miss a session?
• Will my treatment settings be checked again during the course?

If you are using insurance, it is also reasonable to ask the clinic’s administrative team about authorisation, appointment limits and possible out-of-pocket costs. Carriers commonly encountered by New Hampshire providers include Anthem Blue Cross Blue Shield New Hampshire, Harvard Pilgrim Health Care, Cigna, Aetna, UnitedHealthcare, NH Medicaid, Medicare including Advantage plans, and TRICARE East. Coverage and requirements depend on the individual plan and clinical circumstances.
