Localization of hypnopompic seizures - A stereo EEG study.

ABSTRACT: Hypnopompic seizures, characterized by arousal from sleep as the primary clinical manifestation, are a rare and challenging seizure type. Their exact localization has been elusive, often requiring stereotactic EEG (SEEG) for accurate identification. We present the case of a 23-year-old male with drug-resistant focal epilepsy, in whom hypnopompic seizures were localized to the mesial orbitofrontal cortex, with rapid recruitment of the middle temporal gyrus, fusiform gyrus, rostral cingulate, and amygdala. SEEG captured multiple seizures, with arousal occurring 4-5 s after EEG onset, followed by ictal central apnea. The patient underwent resection of the right orbitofrontal and mesial temporal lobe regions and has remained seizure-free for over seven months. This case provides new insights i
