Drug-resistant epilepsy affects 20-30% of children, where early and effective intervention is critical for reducing seizure frequency and neurodevelopmental outcomes, yet it remains a major therapeutic challenge. Pharmacotherapy often fails, and surgery or vagus nerve stimulation is not universally feasible. Repetitive transcranial magnetic stimulation (rTMS) has emerged as a non-invasive neuromodulation strategy that modulates cortical excitability with magnetic pulses. In pediatric populations, rTMS may not only reduce seizure frequency and electrographic abnormalities but also support developmental domains, with adverse effects typically being mild and transient (e.g., scalp discomfort, headache). Beyond seizure reduction, reports describe improvements in cognition, behavior, and quality of life that are particularly relevant for children’s learning and psychosocial development. Mechanistically, rTMS likely acts through two complementary pathways: (i) desynchronization of abnormal cortical oscillations and (ii) modulation of synaptic efficacy via long-term potentiation and long-term depression like plasticity. TMS also has diagnostic and presurgical uses via motor-evoked potentials, paired-pulse paradigms, and TMS-electroencephalography biomarkers, providing clinicians with tools that can inform individualized treatment planning in young patients. However, evidence is heterogeneous, reflecting differences in age, epilepsy subtype, and stimulation parameters, alongside small sample sizes and protocol variability. Concerns specific to pediatrics including the long-term neurodevelopmental safety of repeated stimulation during critical brain maturation remain insufficiently characterized. Practical barriers such as access, cost, and clinician familiarity further limit adoption. This review synthesizes current pediatric rTMS evidence, identifies methodological gaps, and outlines priorities for child-focused trial designs and longitudinal safety monitoring. Advances in neuronavigation, closed-loop stimulation, and artificial intelligence-guided dosing tailored to pediatric neurophysiology could transform epilepsy care by improving precision and individualization for children. rTMS is therefore best positioned as a promising adjunct for carefully selected pediatric patients, delivered within ethically approved, multidisciplinary research settings.
