Residual Sleepiness in Treated Sleep Apnea Linked to Memory Deficits

by GLOOM

Stylized sleep-apnea treatment scene with CPAP, daytime sleepiness testing, and memory-task circuitry, representing cognitive deficits linked to residual sleepiness despite PAP adherence.

Some sleep apnea patients stay sleepy even when their CPAP is used 6+ hours a night and apnea events have been driven back to normal range. A 2026 cross-sectional study of 65 PAP-adherent adults found those residually sleepy patients performed measurably worse on global cognition, memory, executive function, attention, and processing speed than their well-rested …

CPAP Mask Leak Reduced PAP Adherence 7.2% per 10 L/min

MHD featured image for CPAP mask leak, Real Leak, and PAP adherence in obstructive sleep apnea.

A 2026 secondary analysis of the HomePAP trial found that each 10 L/min more unintentional CPAP mask leak was associated with 26.6 fewer PAP minutes per night and 7.2 percentage-point fewer adherent days, but the new Real Leak metric did not significantly outperform ordinary device-reported Average Leak.1 Research Highlights Real Leak tracked poorer adherence: each …
