Abstract: Obstructive sleep apnea syndrome (OSA) is a common respiratory sleep disorder in children that is believed to adversely affect both quality of life and cognition. The purpose of the present systematic review was to obtain evidence of the impact of OSA on children's cognitive/behavioral abilities from primary studies published in MEDLINE/PubMed, LILACS, SciELO, ISI Web of Science, and PsycINFO databases from 2002 to 2016. Of the 649 articles found, only 34 met the eligibility criteria: studies that evaluated cognition, behavior, and/or academic achievement of children meeting clinical criteria for OSA to compare their data to those of healthy controls or normative data, provided that the samples did not present conditions that might affect cognition/behavior irrespective of OSA. The few selected articles with low risk of bias (levels of evidence I and II) showed that OSA children's intellectual abilities may be impaired but remain within the normal range. Which specific cognitive ability drives this impairment is unclear, as there was insufficient evidence of deficits in language, memory, attention, executive functions, and academic performance, due to low levels of evidence, conflicting findings, and/or heterogeneity of tasks and cognitive abilities tapped by the measures used to assess these domains. To determine why this is so, future studies must test OSA patients using measures that allow for fractionated higher-and lower-order cognitive abilities based on accepted cognitive neuropsychology models.
