Polysomnographic and multiple sleep latency studies documented recurrent apneic episodes during NREM sleep stages 1 and 2 and REM sleep in 11 of 16 narcoleptic patients. Episodes were predominantly central, but obstructive and mixed events were also observed. Apneas were accompanied by mild to moderate oxygen desaturation.
