Inclusion Criteria:

1. >18 years old and <65 years old
2. English Speaking, can read and write, and able to provide informed consent
3. Diagnosis of "documented" Functional Seizures as made by an MUSC epileptologist or neurologist using the ILAE recommendations: "by clinician experienced in diagnosis of seizure disorders (on video or in person), showing semiology of typical of FND-seiz, while on EEG plus no epileptiform activity on routine or ambulatory ictal EEG during a typical ictus/event in which the semiology would make ictal epileptiform EEG activity expected during equivalent epileptic seizures"2
4. In addition to meeting ILAE minimum requirements for FND-seiz diagnosis, must have previously undergone and documented in the electronic medical record a minimum of 24-hours of otherwise normal video EEG without interictal epileptiform findings
5. Duration of symptoms >3 months and continuing to experience NES at least monthly
6. Not currently undergoing any psychotherapeutic intervention, agree to forgo any psychotherapeutic intervention during the study, and if previously completed any psychotherapeutic intervention continue to experience monthly non-epileptic seizures
7. If on psychotropic medications may choose to continue during the duration of the study at current doses, but consent to not modifying medication doses or switching to alternative psychotropic regimens during the trial
8. In good general health, as ascertained by medical history
9. Females of reproductive age (ages 18 to 50) must have a negative urine pregnancy test, performed onsite, and documented in the study record within 72 hours prior to the first TMS session

Exclusion Criteria:

1. History of clinical concern for concomitant epileptic seizures or epilepsy
2. History of ongoing psychosis, mania, active alcohol or substance use disorder as screened by the PSQ, YMRS, AUDIT, and DAST-10
3. History of positive screening urine test for drugs of abuse within the last year: cocaine, amphetamines, barbiturates, opiates
4. Active suicidal intent or a score >2 on question 3 of the HAM-D
5. Use of medications known to lower the seizure threshold at doses that may increase this risk in the setting of rTMS-iTBS (i.e. buproprion at >300 mg, combinations of tricyclic antidepressants, antipsychotics… as determined by investigators)
6. History of central nervous system surgeries or clinically relevant structural brain lesions
7. Significant or unstable cardiac, metabolic, oncologic, psychiatric, developmental, or neurologic condition(s) or treatments that may impact safe participation in the study as determined by the study investigators (e.g. poorly-controlled heart failure, current or past cardiac arrhythmia, sustained systolic blood pressure >180, labile diabetes, significant electrolyte abnormality, brain cancer, cognitive impairment, neurodevelopmental disorders, autism spectrum disorder, mania, schizophrenia spectrum or other psychotic disorder, movement disorders, multiple sclerosis, moderate to severe brain injury)
8. Participation in any clinical trial with an investigational drug or device within the past month or concurrent to study participation
9. History of TMS exposure
10. TMS contraindications (e.g., ferromagnetic implants, cochlear implants, conditions or treat-ments that lower seizure threshold - as determined by study investigators).
11. Current pregnancy or desire to become pregnant during study duration without contraceptive plan
12. Are a prisoner or in police custody at the time of eligibility screening
