How We Screen Patients for TMS: Seizure Risk, Medications & Neurologic Conditions

Quick Intro
Safety is our top priority. Before any Transcranial Magnetic Stimulation (TMS) course, Creative Wellness performs a focused medical and psychiatric screen to identify seizure risk, medication interactions, and neurologic conditions that could affect safety or protocol choice. This careful process protects you and helps your care team design the safest, most effective treatment plan.
Why screening matters
TMS is non-invasive and generally well tolerated, but certain medical and neurologic factors can increase the chance of rare side effects -most importantly, seizure. A targeted pre-treatment screen ensures we identify those risks early so we can adapt the plan, select appropriate protocols, or recommend alternate therapies if needed. The screening also clarifies whether medications or implants require special handling.
The core elements of our screening process
1. Comprehensive medical & neurologic history
You’ll be asked about:
- Any prior seizure disorder (epilepsy) or unexplained convulsions
- Prior head trauma, stroke, brain tumor, or progressive neurologic disease
- Any metal implants in or near the head (for example, aneurysm clips, cochlear implants, deep brain stimulators) - implants in or near the skull may rule out TMS or require specialist review
- Other neurologic questions that matter for safety and device placement
These items are standard because they can affect safety and whether TMS is appropriate. If any of these are present, we'll review them with your medical team.
2. Full medication review (psychiatry-led)
Our psychiatry team reviews every prescription, over-the-counter medication, and supplement you take. This matters because certain medications and combinations can affect seizure threshold or interact with TMS care. We screen for interactions and, when needed, coordinate medication adjustments or additional monitoring before a TMS course. Medication screening is part of our routine comprehensive evaluation and ongoing medication management.
3. Risk stratification for seizure and safety
Seizure during TMS is rare, but not impossible. We identify factors that increase seizure risk (for example, known epilepsy, some neurologic lesions, or specific medication interactions) and use that information to:
- Decide if TMS is appropriate
- Choose a conservative stimulation protocol or altered parameters, and
- Plan enhanced monitoring during treatment when needed.
If risk is significant, we’ll discuss alternative treatments or obtain additional neurologic input.
4. Motor mapping & motor-threshold testing
Before the first full course, we perform a mapping/motor-threshold assessment. This is not just to find the treatment target - it also identifies the correct stimulation intensity that is effective while minimizing discomfort and risk. Mapping is a key technical safety step used by specialist clinics.
5. Psychiatric assessment & coordination of care
Our psychiatrists evaluate diagnosis, prior medication trials, and current psychiatric status. They make decisions about continuing or adjusting medications, and they coordinate TMS with medication management or other advanced treatments (for example, Spravato or ketamine) as clinically indicated. This combined-care model improves safety and outcomes.

Common neurologic and implant questions we screen for
- Do you have a history of seizures or epilepsy? (Yes → specialist review)
- Have you had a recent stroke, brain tumor, or neurosurgery? (Yes → review imaging/records)
- Do you have metal in your head/brain (clips, shunts, electrodes)? (Yes → many implants in/near the skull are a contraindication or need neurosurgical clearance)
- Have you had significant head injuries? (Yes → evaluate for residual risk factors)
These focused questions help us identify the small group of patients who require referral or an altered approach.
Medications: what we look for (high-level)
We do not expect patients to know every possible interaction, which is why we take a medication list and do a clinical review. In practice, this means:
- Screening for medications or combinations that lower the seizure threshold or require special monitoring,
- Checking for agents that might affect TMS session tolerance, and
- Coordinating with your prescriber to adjust medications safely if needed.
Our psychiatry team performs medication interaction screening and ongoing safety checks at every follow-up.

What happens if we find a risk
- Minor, manageable risks: We usually adjust the plan (e.g., conservative intensity, extra observation) and proceed with close monitoring.
- Significant risk (e.g., active seizure disorder, incompatible cranial implant): We will pause and arrange further evaluation. Sometimes TMS is contraindicated, and alternative evidence-based treatments will be discussed.
- Unclear cases: We may request prior records, imaging, or a neurology consult to clarify safety before starting. The decision is always made with your safety and the best outcome in mind.
How we explain risk and get informed consent
We review benefits, expected side effects (including the uncommon possibility of seizure), and the specific findings from your screening. You’ll meet with a clinician to discuss the plan, and we’ll answer questions before you sign informed consent. This transparency and shared decision-making are part of our standard of care.
Practical tips for patients before screening
- Bring a complete medication list (prescription, OTC, supplements.
- Bring records of any prior seizures, neurologic imaging (CT/MRI), or neurosurgical reports if you have them.
- List prior psychiatric medication trials (drug, dose, dates, response).
- Tell us about implants or implanted devices, even if you think they aren’t relevant. It’s safer to disclose and let clinicians assess.
Does TMS cause seizures?
Seizures during TMS are very rare. Clinics screen carefully for seizure risk and adjust protocols or decline treatment when risk is significant to keep patients safe.
Can I have TMS if I take psychiatric medications?
Often yes. We perform a medication review and coordinate with your psychiatrist to manage interactions or adjust medications as needed. Medication management is an integrated part of our TMS care.
What about metal implants or devices?
Implants in or near the head may be a contraindication and require specialist review. Tell us about any implants so we can assess safety.
Will you still do TMS if I had a brain injury years ago?
It depends on the injury and residual risk. We review records and may request imaging or neurology input before recommending TMS. Most decisions are individualized.
