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 into the neuroanatomical origins of seizure-induced arousal, identifying the mesial orbitofrontal cortex as a potential site for hypnopompic seizures. The findings underscore the critical role of SEEG in accurately localizing seizure foci in complex epilepsy cases, enabling targeted surgical interventions.

The known mutations underlying the two spectra are different, but there are multifold population-genetic-, family- and even individual (the two conditions occurring in the same person) overlaps supporting common genetic roots. In the episodes of disorders of arousal, the anterior cingulate, anterior insular and pre-frontal cortices (shown to be involved in fear- and emotion processing) are activated within a sleeping brain. These regions overlap with the seizure-onset zones of successfully operated sleep-related hypermotor seizures, and notably, belong to the salience network being consistent with its hubs. The arousal-relatedness and the similar fearful confusion occurring in sleep terrors and hypermotor seizures, make them alike acute stress-responses emerging from sleep; triggered by false alarms. The activation of the anterior cingulate, prefrontal and insular regions in the episodes of both conditions, can easily mobilize the hypothalamo-pituitary-adrenal axis (preparing fight-flight responses in wakefulness); through its direct pathways to and from the salience network.
