Epilepsy Clinical Trial
Official title:
Use of Transcranial Magnetic Stimulation (TMS) as a Surrogate of Pathophysiology in Genetic Epilepsies
Transcranial magnetic stimulation (TMS) uses electromagnetic induction as an efficient, painless, non-invasive method to generate a suprathreshold current at the level of the encephalon, and provide in vivo measurements of cortical excitability and reactivity at the level of the motor cortex (TMS-EMG) or the entire cortical mantle (TMS-EEG). This study proposes TMS measurements as a diagnostic tool in patients to understand mechanisms of epileptogenesis related to genetic mutations, and prognostic to guide and monitor precision treatments.
