Demographic and nap-related variance of the MSLT: results from 2,498 suspected hypersomnia patients: Clinical MSLT variance.

ABSTRACT:

Objective

The purpose of this study was to enhance our understanding of clinical trends in sleep and rapid eye movement (REM) propensity on the multiple sleep latency test (MSLT). Demographic variables of interest included early childhood/advanced age, gender, race, and REM-suppressant use.

Methods

Nocturnal sleep studies and 5-nap MSLTs were retrieved from a large repository of deidentified studies from various US sleep clinics between 2007 and 2015. Studies were signal processed, human-edited, and underwent rigorous quality assurance for inclusion.

Results

The final sample consisted of N = 2498 MSLTs (24.2% Black; 34.2% Men; Age 4-89). In adults (age ≥ 21), sleep propensity modestly decreased across nap (90% at nap 1 to 80% at nap 5; p < 0.001). Children ≤12 years w
