Long term protocol: Perform non-invasive neuro-navigated repeated Transcranial Magnetic Stimulation (rTMS) at low frequencies (LF) with to reduce the occurrence of seizures over time. Seizure reduction and improvements in the quality of life in patients with epilepsy will be associated with increased cortical inhibition resulting from the LF-rTMS sessions over time. This procedure using rTMS at low frequencies (LF-rTMS) between 0.5 and 1 Hz is a safe and painless method for noninvasive focal cortical brain stimulation, which will be evaluated in its efficacy at reducing/suppressing seizures. Accordingly, we propose a clinical trial in patients with epilepsy to test whether LF-rTMS can improve seizure suppression. The location of the presumed 3D source in the brain will be stimulated for few minutes (10 to 15 min.). Using a double-blinded, sham-controlled design, we will enroll up to 100 participants aged 18-80 with focal and generalized retractable epilepsy. Baseline data will include a detailed seizure diary over 4 weeks, psychometric testing/neuropsychology evaluation, and 20-minute EEG recordings. Each patient will then begin treatment with 14 minute sessions of 1 Hz rTMS or sham rTMS, 120%MT, and 800 stimuli on the position of the calculated 3D source using EEG, MRI, and digitized electrode locations. The protocol will be divided in 3 groups (Groups 1, 2 and 3) as follows:~Groups 1, 2, and 3: LF-rTMS for 2 weeks (5 days per week for total of 10 days).~Group 1: protocol total duration: 1 year: LF-rTMS 1 session/week for 1 month (4 days), and LF-rTMS 1 session/month for 11 months~Group 2: protocol total duration: 1 year: LF-rTMS 1 session/month for 12 months~Group 3 (placebo protocol, total duration: 1 year): LF-rTMS 1 session/week for 1 month (4 days); and LF-rTMS 1session/month.~During each session EEG may be recorded. Also, we will obtain the number, frequency, and duration of seizure events from an ongoing seizure diary. Psychometric testing will be performed at the beginning of study, 3 months, and at the end of the study. Thus, each patient will have rTMS testing, psychometrics, and EEG recordings. With the same rTMS modality, we will also perform motor threshold mapping in conjunction with its fully integrated and compatible electroencephalography (EEG) module.~Short-term protocol: Use LF-rTMS protocol as described but for up to 5 days in 10 participants with medically refractory status epilepticus. During each session EEG will be recorded.
Perform non-invasive neuro-navigated repeated Transcranial Magnetic Stimulation (rTMS) at low frequencies (LF) with the intent to reduce the occurrence of seizures over time (long-term protocol).
