Allowing ad libitum sleep during overnight polysomnography affects Multiple Sleep Latency Test results in patients being assessed for hypersomnolence.

ABSTRACT:

Study objectives

The Multiple Sleep Latency Test (MSLT) is a key diagnostic component in the diagnosis of central disorders of hypersomnolence. Due to time constraints, it is common practice to wake patients at a standard time from overnight polysomnography (PSG) prior to the MSLT. This has the potential to influence MSLT results due to sleep deprivation. We describe the impact of allowing ad libitum sleep on the night prior to the MSLT in patients being assessed for hypersomnolence.

Methods

A total of 580 consecutive patients undergoing PSG/MSLT for assessment of hypersomnolence were analyzed: 290 either side of a change in laboratory protocol that allowed patients ad libitum sleep during the PSG, rather than being woken at a prespecified time. Baseline characteristics, PSG
