[Sleepiness, continuous positive airway pressure and the obstructive sleep apnea hypopnea syndrome].
Excessive daytime sleepiness is a major symptom in cases of the obstructive sleep apnea-hypopnea syndrome. Most often, it is vastly improved by treatment with continuous positive airway pressure (CPAP). The most effective way to confirm its disappearance is through wakefulness maintenance testing. ⋯ In some rare cases (about 6% of patients) investigations will reveal central hypersomnia due to the obstructive sleep apnea-hypopnea syndrome or "lesional" hypersomnia due to intermittent hypoxia. Since 2011, medications treating excessive sleepiness have had marketing authorization only for narcolepsy in France. However, they can be administered by way of derogation to other neurological hypersomnias on prescription by a reference centre or a centre with expertise in hypersomnia.
