TMS Side Effects and Safety: A Georgia Patient Guide

TMS Side Effects and Safety: A Georgia Patient Guide

Transcranial magnetic stimulation (TMS) is a non-invasive treatment that uses magnetic pulses to stimulate specific areas of the brain. It is most often considered for adults with major depressive disorder when other treatments, such as medication or talking therapy, 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, you remain awake and can usually return to ordinary activities afterwards.

Like any medical treatment, TMS has possible side effects and safety considerations. A proper assessment by a qualified clinician is important before treatment starts. This guide explains what patients in Georgia may wish to know and what information to share with a TMS provider.

What treatment feels like

During a TMS session, a clinician places a magnetic coil against the scalp. The device produces brief magnetic pulses, often accompanied by a tapping sound and a sensation on the skin or scalp.

The exact sensation varies from person to person. Some people describe tapping, tingling, pressure or mild discomfort around the treatment area. The clinician can adjust coil placement and stimulation settings where appropriate, particularly during the early sessions when you are becoming used to the treatment.

A standard course is often around 36 weekday sessions, delivered over roughly six to nine weeks. The appointment itself may be relatively brief, but the full treatment plan requires regular attendance. Your clinic should explain its proposed schedule, monitoring arrangements and what to do if you need to miss a session.

Common side effects

The most commonly reported side effects of TMS are scalp discomfort and headache. These are generally mild to moderate and often become easier to tolerate as treatment continues.

Scalp discomfort

The magnetic coil may cause discomfort, pressure or tenderness at the point where it rests against the head. Some people find the tapping sensation unpleasant at first. This is not the same as an electric shock: the treatment uses magnetic pulses applied outside the head.

Tell the treatment team if discomfort is affecting you. They may be able to check the coil position, review the settings or discuss practical ways to make sessions more comfortable. Do not assume you need to put up with pain without mentioning it.

Headache

Headache can occur during or after a session. For many people, it is temporary and manageable. Your clinician can advise whether a usual over-the-counter pain medicine is suitable for you, taking account of your health history and other medicines.

It is sensible to report headaches that are severe, persist, change in character, or occur with other concerning symptoms. Your treatment team can decide whether you need further assessment.

Other temporary effects

Some people may experience tiredness, light-headedness, facial muscle twitching near the treatment area, or temporary irritation from the noise and repeated tapping. TMS sessions involve audible clicking, so clinics commonly provide hearing protection.

Side effects should be documented and discussed throughout the course, not only at the first appointment. A clinic should give you clear instructions on who to contact between sessions if you have a concern.

Rare but serious risks

A seizure is a rare but important risk of TMS. For this reason, screening before treatment matters. The risk may be higher in people with certain neurological conditions, a personal history of seizures, significant sleep deprivation, heavy alcohol use or withdrawal, or medicines that can lower the seizure threshold.

The clinician should review these factors carefully and decide whether TMS is appropriate. If treatment goes ahead, the team should have procedures in place to respond to an emergency.

You should seek urgent medical help for a seizure, loss of consciousness, serious injury, or severe symptoms that feel unusual or alarming. Your clinic should also explain its own urgent-contact arrangements before your first session.

TMS is not designed to cause memory loss. It differs from electroconvulsive therapy (ECT), which is another treatment with a different procedure, anaesthetic requirements and side-effect profile. If memory or concentration is a particular concern for you, ask your clinician to explain the expected benefits and risks of the treatment options being considered.

Who may not be suitable for TMS?

TMS is not suitable for everyone. One key concern is metal or electronic equipment in or near the head, because the magnetic field may interact with certain implanted devices or materials.

Examples that need careful clinical review include:

• cochlear implants;
• implanted neurostimulators or other electronic devices;
• metal clips, plates, fragments or foreign bodies in or close to the head;
• some aneurysm clips or other surgical implants;
• a history of eye injury involving metal fragments.

This does not automatically mean every item of metal prevents treatment. For example, ordinary dental fillings, braces and many dental implants may not be a barrier. However, the clinician needs accurate details about what is present, where it is located and, where possible, the make or medical records for the implant.

Do not rely on an internet checklist or assume that an older operation is irrelevant. Tell the clinic about any previous head, brain, ear, eye, neck or facial surgery, even if it took place many years ago.

A history of epilepsy, seizures, stroke, brain injury, neurological illness or fainting episodes should also be discussed. So should bipolar disorder, psychosis, or a history of mania or hypomania. These conditions do not necessarily rule out treatment, but they may change the assessment, monitoring or wider treatment plan.

What to tell your clinician before treatment

A thorough consultation should cover your mental health, physical health, medicines and practical circumstances. Being open helps the clinician assess safety and avoid preventable problems.

Before starting TMS, tell the clinician about:

• any seizures, epilepsy, head injury, stroke or neurological condition;
• any metal, implants, devices or previous surgery involving your head, neck, ears or eyes;
• all prescribed medicines, over-the-counter medicines, supplements and recreational substances;
• alcohol use, including recent heavy use or possible withdrawal;
• changes in sleep, particularly severe insomnia or prolonged sleep deprivation;
• pregnancy, plans for pregnancy or breastfeeding;
• a diagnosis or possible history of bipolar disorder, mania, hypomania, psychosis or substance use problems;
• hearing concerns, including hearing aids or ear conditions;
• allergies, recent illness and any new symptoms since your assessment.

Bring an up-to-date list of medicines where possible. Do not stop, start or change medication solely because you are considering TMS without speaking to the clinician who prescribes it. Medication changes can affect both your wellbeing and the safety assessment.

It is also important to update the team during the course. Tell them if you begin a new medicine, become unwell, experience a major change in sleep, drink substantially more alcohol than usual, or have any new head injury or neurological symptom.

Questions to ask a Georgia TMS clinic

Georgia patients may find that clinics differ in their referral pathways, assessment process and insurance arrangements. The directory currently lists 255 published clinics across the state, including listings in Atlanta, Alpharetta, Johns Creek, Grovetown, Snellville, Cumming, Columbus, Evans, Pooler, Sandy Springs, Norcross and Smyrna.

When speaking with a clinic, useful questions include:

• Who will carry out my assessment and oversee treatment?
• How will you check whether metal implants or medical conditions affect safety?
• What side effects should I report straight away?
• What happens if I experience significant discomfort during a session?
• What is your procedure if a seizure or other urgent event occurs?
• How will my existing psychiatrist, GP or other prescriber be involved?
• How many sessions do you recommend, and how will progress be reviewed?
• What are the likely out-of-pocket costs and prior authorisation requirements?

Insurance coverage depends on your individual plan, diagnosis, clinical history and provider network. Plans commonly encountered in Georgia include Anthem Blue Cross Blue Shield Georgia, Aetna, Cigna, UnitedHealthcare, Humana, Peach State Health Plan / Georgia Medicaid, Medicare including Advantage plans, and TRICARE East. A clinic may help check benefits, but it is wise to confirm coverage directly with your insurer as well.
