Group 1: Weekly TMS
LF-rTMS intervention for 2 weeks (5 days per week for total of 10 days) , LF-rTMS 1 session/week for 1 month (4 days), and LF-rTMS 1 session/month for 11 months
Low frequency repeated TMS (LF-rTMS): Each patient will then begin treatment with 14 minute sessions of 1 Hz rTMS or sham rTMS, 120% minimum threshold (MT), and 800 stimuli on the position of the calculated 3D source using EEG, MRI, and digitized electrode locations. Two different timelines of delivering the rTMS will be compared against a sham/delayed treatment group.

Timeframe: 8-weeks Post rTMS TreatmentPopulation: Data was based on standardized threshold of 80% across 20 Epochs
Standardized functional scalp EEG connection per of region (anterior, posterior, right, and left). Calculations required EEG electrode activity of 80% for a minimum of 20 epochs to be included. All area electrode counts were then divided by the threshold providing a normalized value per brain region. Scalp EEG connectivity was collected 8-weeks post rTMS treatment.

SECONDARY outcome
Timeframe: 8-weeks Post rTMS treatmentPopulation: Post APB-evoked response was not collected, therefore cannot be analyzed.
The motor evoked potential (MEP) will be calculated using the Nexstim system's 6-channel EMG module (SR=1450 Hz, cut-off frequency of 350 Hz for the low pass filter) as the APB is stimulated to find the threshold for each individual. Listed values represent the percentage of the maximum Tesla output of the Nexstim system.

Short-term Protocol
LF-rTMS intervention daily for up to 5 days in medically refractory status epilepticus participants only
Low frequency repeated TMS (LF-rTMS): Each patient will then begin treatment with 14 minute sessions of 1 Hz rTMS or sham rTMS, 120% minimum threshold (MT), and 800 stimuli on the position of the calculated 3D source using EEG, MRI, and digitized electrode locations. Two different timelines of delivering the rTMS will be compared against a sham/delayed treatment group.

Group 1: Weekly TMS
n=1 Participants
LF-rTMS intervention for 2 weeks (5 days per week for total of 10 days) , LF-rTMS 1 session/week for 1 month (4 days), and LF-rTMS 1 session/month for 11 months
Low frequency repeated TMS (LF-rTMS): Each patient will then begin treatment with 14 minute sessions of 1 Hz rTMS or sham rTMS, 120% minimum threshold (MT), and 800 stimuli on the position of the calculated 3D source using EEG, MRI, and digitized electrode locations. Two different timelines of delivering the rTMS will be compared against a sham/delayed treatment group.

Group 2: Monthly TMS
LF-rTMS intervention for 2 weeks (5 days per week for total of 10 days), LF-rTMS 1 session/month for 12 months
Low frequency repeated TMS (LF-rTMS): Each patient will then begin treatment with 14 minute sessions of 1 Hz rTMS or sham rTMS, 120% minimum threshold (MT), and 800 stimuli on the position of the calculated 3D source using EEG, MRI, and digitized electrode locations.

SECONDARY outcome
Timeframe: 8-weeks Post rTMS TreatmentPopulation: left posterior electrodes are divided by the anterior electrodes
Expresses the asymmetry power ratio for the corresponding electrode pairs between the posterior and anterior brain regions, where the left posterior electrodes are divided by the anterior electrodes.

Group 3: Sham TMS
Sham LF-rTMS for 2 weeks (5 days per week for a total of 10 days), sham LF-rTMS 1 session/week for 1 month (4 days), and sham LF-rTMS 1 session/month for 1 month. After the sham stimulation real LF-rTMS intervention sessions will be delivered as follows: 50% of placebo group will follow group 1 protocol and the other 50% will follow group 2 protocol
Low frequency repeated TMS (LF-rTMS): Each patient will then begin treatment with 14 minute sessions of 1 Hz rTMS or sham rTMS, 120% minimum threshold (MT), and 800 stimuli on the position of the calculated 3D source using EEG, MRI, and digitized electrode locations.
