NCT00560456

Brief Summary

Young subjects and patients with nocturnal respiratory disorders are frequently involved in sleep-related accidents. This study assess the impact of chronic sleep restriction (4 hr of sleep during 5 days) or total sleep deprivation in young or mature healthy subjects or snorers on simulated driving, objective and subjective sleepiness and objective and subjective cognitive performances. The effects of recovery night on these parameters are also assessed.
