30% of patients with epilepsy suffer from drug-resistant seizures and are at risk of epilepsy-related complications, from cognitive dysfunctions to premature mortality. Both seizures and their complications are modulated by patients' vigilance states, with a tight and bi-directional interplay between sleep and epilepsy. Several epilepsy complications are associated with sleep, such as sleep-disordered breathing or Sudden and Unexpected Death in Epilepsy (SUDEP). SUDEP is a non-traumatic death, unrelated to a documented status epilepticus, which accounts for up 50% of premature deaths in epilepsy, with a cumulative risk of ≈ 10% at 40 years in patients with childhood-onset epilepsy. SUDEP typically occurs during sleep, after a nocturnal seizure, and primarily results from a postictal central respiratory dysfunction in patients with generalized convulsive seizure (GCS), suggesting that interaction between respiratory dysfunction and sleep state may play a role in its pathophysiology. Most of patients with drug-resistant seizures demonstrate transient peri-ictal apnea and hypoxemia, especially in the aftermath of a GCS. Experimental and clinical data suggest that most SUDEP primarily result from a fatal seizure-related respiratory arrest. In patients whose SUDEP had occurred during long-term video-EEG monitoring, we observed fatal postictal central apnea after a nocturnal GCS in all SUDEP. Accordingly, it is currently hypothesized that in a subgroup of patients, repetition of s…
