Daytime Sleepiness, Apnea, Neuroimaging Correlates and Cortisol Dysregulation in a Memory Clinic Cohort.

The association between sleepiness index and awakening cortisol was only significant in females [Females: β = -0.05, p = 0.025, Males: β = −0.01, p = 0.598], whereas the association between apnea index and awakening cortisol was non-significant in both sexes, although closer to significance for males [Females: β = −0.02, p = 0.428, Males: β = −0.04, p = 0.061].
