The Wyoming guide says TMS for depression is non-invasive, usually causes temporary scalp discomfort or headaches, and requires screening for uncommon risks.

TMS Side Effects and Safety: A Wyoming Patient Guide

Transcranial magnetic stimulation (TMS) is a non-invasive treatment that uses magnetic pulses to stimulate targeted areas of the brain. It is most often considered for major depressive disorder, particularly when other treatments have not provided enough relief or have caused difficult side effects.

TMS was cleared by the FDA for major depressive disorder in 2008, and for depression with comorbid anxiety in 2021. It does not involve surgery, anaesthesia or implanted electrodes. During treatment, a clinician places a magnetic coil against the scalp while you are awake and seated comfortably.

For people considering TMS in Wyoming, it is useful to understand the likely side effects, the uncommon but important risks, and the health information a clinic needs before treatment begins.

What treatment feels like

A TMS appointment usually involves sitting in a treatment chair while the clinician positions the coil over a specific part of the scalp. The machine produces clicking sounds and delivers repeated magnetic pulses. You may feel tapping, tingling or a pulling sensation in the scalp or forehead area.

A standard course commonly involves weekday appointments over several weeks, often around 36 sessions in total. Individual treatment plans can differ, including the type of TMS used and the length of each appointment.

Before a full course begins, the clinician will usually carry out an assessment and determine the correct coil placement and pulse intensity. This process helps tailor treatment to you and is also an opportunity to discuss safety concerns, medicines and medical history.

Common TMS side effects

Most TMS side effects are mild to moderate and occur during treatment or shortly afterwards. They often improve as you become accustomed to the sessions, or after the clinician adjusts the treatment settings.

The most commonly reported effects are:

  • Scalp discomfort or sensitivity where the coil rests
  • Headache
  • Facial muscle twitching during pulses
  • Tingling or a tapping sensation around the forehead or jaw
  • Temporary tiredness after an appointment
  • Mild light-headedness in some people

Scalp discomfort is often most noticeable during the first sessions. The sensation can vary depending on the individual, the placement of the coil and the treatment intensity. Tell the treatment team if it is painful rather than merely uncomfortable. They may be able to adjust the coil position, intensity or other aspects of the session.

Headaches can also occur, particularly early in a course. They are usually temporary. Your clinician can advise whether your usual pain relief is suitable, taking account of your medical history and other medicines.

Although TMS does not generally require sedation, it is still sensible to notice how you feel after each appointment. If you feel unusually unwell, dizzy or unable to continue your normal activities, contact the clinic for advice.

Rare but serious risks

The most significant rare risk associated with TMS is a seizure. Seizures during properly screened and delivered TMS treatment are uncommon, but the possibility is important to discuss before starting.

A seizure is a sudden episode of abnormal electrical activity in the brain. The risk may be higher for people with a history of seizures or epilepsy, certain neurological conditions, significant sleep deprivation, heavy alcohol use or withdrawal, or medicines that can affect seizure threshold.

TMS clinics use screening procedures and treatment protocols designed to reduce risk. This is why it is important to answer health questions fully, including questions that may not seem directly related to depression.

Other reasons to seek urgent medical advice include a severe or unusual headache, fainting, a suspected seizure, new neurological symptoms, or a marked deterioration in mental health. If you are in immediate danger or at risk of harming yourself, seek emergency help straight away.

Who may not be suitable for TMS?

TMS is not right for everyone. Eligibility depends on the type and location of any implanted device or metal, your medical history, current medicines and the clinician’s assessment.

In particular, tell the clinician if you have metal in or near your head. Some metal implants or fragments may be affected by the magnetic field. This can include certain aneurysm clips, cochlear implants, implanted stimulators, metal fragments from an injury, or other devices in the head or neck area.

Do not assume that dental work automatically rules out treatment. Many people have dental fillings, crowns or braces, but the clinic still needs to know about them. The treating team can determine whether a particular item presents a concern.

You should also mention any implanted medical device, such as a pacemaker, neurostimulator, medication pump or other electronic implant. Whether TMS is appropriate may depend on the specific device, where it is located and the manufacturer’s guidance.

A history of seizures does not always mean that TMS is impossible, but it requires careful discussion. The same applies to a history of brain injury, stroke, brain surgery, a tumour, or other neurological conditions. The clinic may need further records or may recommend another approach.

What to tell your TMS clinician

A thorough assessment is one of the most important parts of safe TMS care. Bring a current list of medicines and be prepared to discuss your health history openly.

Tell the clinician about:

  • Any previous seizure, epilepsy diagnosis, fainting episodes or unexplained loss of consciousness
  • Head injuries, concussion, stroke, brain surgery or neurological illness
  • Metal in or near the head, including fragments from an accident or work injury
  • Cochlear implants, implanted stimulators, pumps, pacemakers or other electronic devices
  • Prescription medicines, over-the-counter treatments, supplements and recreational substances
  • Recent medicine changes, including changes in dose
  • Alcohol use, especially heavy use or plans to stop suddenly
  • Sleep problems or recent severe sleep deprivation
  • Pregnancy, plans for pregnancy or breastfeeding
  • Bipolar disorder, psychosis, mania or a family history of these conditions
  • Current suicidal thoughts, self-harm, or a sudden worsening in mood or anxiety

It is also important to tell the team if your circumstances change during treatment. Starting a new medicine, missing several nights of sleep, increasing alcohol use, becoming unwell, or experiencing a new symptom may affect how safely treatment can proceed.

Do not stop prescribed medicines suddenly in preparation for TMS unless the clinician who manages those medicines has advised you to do so.

Questions to ask before treatment

A reputable clinic should make time for questions. You may wish to ask:

  • Why do you think TMS is suitable for me?
  • What type of TMS do you offer, and what will a typical appointment involve?
  • What side effects should I expect in the first few sessions?
  • What should I do if scalp discomfort or headache becomes difficult?
  • How will you assess my seizure risk?
  • Which of my medicines or health conditions need particular review?
  • Who should I contact outside appointment hours if I have concerns?
  • How will you monitor changes in depression, anxiety and safety during treatment?

You may also want to ask about practical arrangements, including attendance requirements and insurance checks. In Wyoming, patients may encounter coverage arrangements involving Blue Cross Blue Shield of Wyoming, UnitedHealthcare, Cigna, Aetna or Wyoming Medicaid (EqualityCare). Coverage depends on your individual plan, clinical criteria and the provider’s billing arrangements, so confirm details directly before beginning treatment.
