Hz generalized spike-and-slow wave bursts of 1 second duration with maximal spike amplitudes over frontal regions (Fig. 1). Epilepsy protocol magnetic resonance imaging of her brain was normal. Her seizures proved difficult to control from age 17 when generalized tonic-clonic seizures recurred reaching a frequency of up to four seizures per month, despite trials of zonisamide, lamotrigine, levetiracetam and clobazam.
