TMS in Iowa is an outpatient depression treatment that commonly causes temporary scalp discomfort or headaches, while clinicians assess rare risks and suitability before care.
TMS Side Effects and Safety in Iowa
Transcranial magnetic stimulation (TMS) is a non-invasive treatment that uses magnetic pulses to stimulate areas of the brain involved in mood. It is most commonly considered for major depressive disorder, particularly when medicines or talking therapies have not provided enough relief or have caused difficult side effects.
TMS is generally provided as an outpatient treatment. You remain awake, sit in a treatment chair and can return home afterwards. A standard course often involves weekday appointments over six to nine weeks, commonly around 36 sessions in total.
The US Food and Drug Administration first cleared TMS for major depressive disorder in 2008, and later cleared it for depression with comorbid anxiety in 2021. As with any treatment, it is important to understand the possible side effects, uncommon risks and the information your clinician needs before treatment begins.
The most common side effects
Most people who have TMS experience either no significant side effects or mild, temporary effects. The most commonly reported issues are discomfort on the scalp during treatment and headache afterwards.
During a session, the magnetic coil is placed against the scalp. The pulses can feel like tapping, knocking or a brief tightening sensation. Some people find the first few sessions uncomfortable, especially while they are getting used to the sensation. The treating team can often adjust aspects of the setup or gradually increase the treatment intensity where appropriate.
Common effects can include:
- Scalp discomfort or tenderness where the coil is positioned
- Headache during or after a session
- Mild facial muscle twitching during pulses
- Temporary fatigue
- Light-headedness or mild dizziness in some people
Headaches and scalp discomfort are usually short-lived. Your clinician may suggest simple measures such as rest, hydration or an appropriate over-the-counter pain reliever, if this is safe for you. Do not start or change medicines without checking with a healthcare professional, particularly if you take prescribed medication or have other health conditions.
It is useful to tell the treatment team exactly what you feel during a session. They may be able to alter the coil position, check its fit or discuss whether the treatment setting should be reviewed.
What TMS should not feel like
TMS should not involve surgery, needles or anaesthesia. You should remain conscious and able to speak to staff throughout treatment. The magnetic pulses do not normally cause memory loss, and TMS is not the same as electroconvulsive therapy (ECT).
That said, discomfort should be discussed rather than simply endured. Let the clinician know if pain becomes difficult to manage, if a headache is severe or unusually persistent, or if you develop new symptoms that concern you between sessions.
Seek urgent medical help for severe or sudden symptoms, such as a seizure, loss of consciousness, severe confusion, chest pain, difficulty breathing or signs of a serious allergic reaction to any medicine you may have taken.
The rare risk of seizure
Seizure is a rare but recognised risk of TMS. Clinics assess this risk carefully before starting treatment and should review changes that could affect it during the course.
Certain factors may increase seizure risk. These can include a personal history of seizures or epilepsy, a recent significant head injury, some neurological conditions, heavy alcohol use or abrupt alcohol withdrawal, recreational drug use, severe sleep deprivation, and medicines that can lower the seizure threshold.
This does not automatically mean that TMS is unsuitable. It means the clinician needs a complete picture and may need to seek further medical information, adjust the plan or recommend a different approach.
Be particularly open about changes during treatment. For example, tell the clinic if you have started a new prescription, stopped a medicine suddenly, changed your alcohol intake, been unwell, had very little sleep, or used non-prescribed substances. These details are relevant to safe treatment planning.
Metal, implants and other precautions
TMS uses a powerful magnetic field near the head. Some metal objects or implanted devices may make TMS unsuitable, depending on their type and location.
Before treatment, tell the clinician about any metal in or near your head, including clips, coils, plates, screws, shrapnel or retained fragments. This is particularly important if the metal is not designed to be safely exposed to magnetic fields.
You should also disclose implanted medical devices, such as:
- Cochlear implants or other hearing devices
- Implanted stimulators
- Medication pumps
- Devices used for neurological or cardiac care
- Any implant where you are unsure of the material or its location
Do not assume an implant is irrelevant because it is old or because another healthcare setting has previously scanned or treated you. Bring details where possible, such as implant cards, operation records or the name of the surgeon or hospital involved. The TMS clinician can determine whether further checks are needed.
Hearing protection is normally used during TMS because the coil makes a repeated clicking sound. Tell staff if you have hearing loss, tinnitus, ear pain or concerns about wearing earplugs.
What to tell your TMS clinician
A careful assessment is an important part of TMS safety. Be ready to discuss your mental health history, physical health, medicines and daily circumstances honestly. The purpose is not to rule people out unnecessarily; it is to help the clinician make an informed recommendation.
Tell the clinician about:
- Any past seizure, epilepsy diagnosis, fainting episode or unexplained loss of consciousness
- Head injuries, stroke, brain surgery, neurological illness or severe migraines
- Metal fragments, implants, cochlear implants or other implanted devices
- All prescription medicines, over-the-counter products, vitamins and supplements
- Recent medication changes, including missed doses or stopping medicines
- Alcohol use, recreational drug use and any recent withdrawal symptoms
- Sleep problems, especially major sleep loss before an appointment
- Pregnancy, plans for pregnancy or breastfeeding
- Hearing concerns or ear conditions
- Previous TMS, ECT or other psychiatric treatments
- Any worsening depression, agitation, unusual mood elevation, psychosis or thoughts of self-harm
If you are at immediate risk of harming yourself or someone else, contact emergency services or go to the nearest emergency department. TMS treatment planning is not a substitute for urgent crisis care.
Questions to ask before starting
It can help to write down questions before your consultation. You may want to ask how the clinic screens for seizure risk, what happens if you have pain during treatment, whether the treatment protocol is appropriate for your diagnosis, and how changes in medication will be handled.
You can also ask who will be present during sessions, how to contact the clinic between appointments, and what the plan would be if you miss appointments because of illness, travel or another issue.
Cost and cover may also affect practical decisions. In Iowa, insurers commonly encountered include Wellpoint, UnitedHealthcare, Aetna, Cigna, Iowa Total Care, Molina Healthcare of Iowa, Iowa Medicaid and Medicare. Cover, prior authorisation requirements and eligibility can vary by plan and by treatment provider, so confirm details directly with both the clinic and your insurer.
