Summary

The purpose of this study is to investigate a novel stimulation protocol of repetitive transcranial magnetic stimulation (rTMS) for the treatment of unifocal neocortical epilepsy, namely continuous thetaburst stimulation (cTBS). As this is a pilot study, the primary endpoint is on safety and tolerability of the treatment. However, information on clinical efficacy and mechanism of action will also be collected.

Interventions

DEVICE

continuous thetaburst stimulation

On 4 consecutive days patients receive 5 cTBS trains with a 10min intertrain-interval. One cTBS train consists of 600 pulses delivered in bursts at theta frequency (200ms) during 40s. Each burst comprises 3 pulses at 50Hz. Focal stimulation occurs over the epileptogenic focus (EF), perpendicular to the local gyral geometry, using online neuronavigation. Stimulation intensity is set relative to the resting motor threshold (rMT) determined at baseline (80% rMT). Stimulation intensity is further adjusted to the coil-cortex distance at the EF with the following formula: adjusted MT% (AdjMT) = rMT + 2,7\*(DEF-DM1) \[DEF = distance over EF; DM1 = distance over M1\]. If rMT exceeds the capacity of the stimulator output, stimulation intensity is 100% of maximal stimulator output (MSO).
