    The study analyzed 130 adults, 68 with ADHD and 62 with excessive daytime sleepiness (EDS) but without ADHD, undergoing Multiple Sleep Latency Testing.

    Subjective sleepiness, measured by the Epworth Sleepiness Scale, showed no significant difference between the ADHD group (median score 14.0) and the EDS-only group (median score 13.0).

  • 3

    Objective sleep propensity differed significantly, with the ADHD group having a longer median mean sleep latency of 432.0 seconds compared to 322.0 seconds in the EDS-only group.

  • 4

    MSLT positivity was less frequent in the ADHD group at 61.8% compared to 87.1% in the EDS-only group, indicating a lower objective sleep propensity.

  • 5

    Within the ADHD group, ESS scores were not significantly correlated with mean sleep latency, contrasting with a significant inverse correlation in the MSLT-positive EDS-only subgroup.
