Neuropsychological correlates of obstructive sleep apnea severity in patients with epilepsy Volume 21, issue 1, February 2019

TEST YOURSELF

(1) When left untreated, obstructive sleep apnea can have major impact on cognition. Which cognitive domains are particularly affected by obstructive sleep apnea in the general population?

(2) According to this study, which cognitive domains seem particularly affected by more severe obstructive sleep apnea in epilepsy?

(3) When designing a prospective study to examine the effects of obstructive sleep apnea on cognitive functioning in patients with epilepsy and whether treatment of obstructive sleep apnea may help improve cognition, what would be the most sensitive OSA-related measure?

Answers

(1) In the general population, obstructive sleep apneahas significant negative impact on attention/executive functions and memory processes.

(2) In adults with epilepsy, more severe OSA is associated with poorer performances on tests assessing attention/executive as well as memory functions.

(3) According to our results, OSA-related hypoxemia variables may be more sensitive measures of the effects of OSA on cognition, by contrast to the sole frequency of apnea events per hour.
