Controllable Yawning Expressed as Focal Seizure of Frontal Lobe Epilepsy

We present the first case of controllable yawning as a primary seizure semiology with dominant frontal lobe involvement in a 20year-old-man. Video electroencephalography recorded 8 yawning episodes accompanied with right arm movement correlating with rhythmic diffuse theta range activity with left hemispheric predominance. Magnetoencephalography-Coherence Source Imaging was consistent with persistent neuronal networks with areas of high coherence reliably present over left lateral orbito-frontal region. Epileptogenic areas may have widespread networks involving the dominant frontal lobe symptomatogenic areas.
