Obstructive sleep apnea (OSA) is accompanied by significant daytime cognitive and behavioral deficits that extend beyond the effects of sleepiness. This article outlines a causal model by which to understand these psychological effects among OSA patients. The model proposes that sleep disruption and blood gas abnormalities prevent sleep-related restorative(More)
This article summarizes correlational, case-control, quasi-experimental, and experimental studies that have examined whether sleep during childhood and adolescence is related to daytime functioning. Published findings suggest that inadequate sleep quality and/or quantity can cause sleepiness, inattention and, very likely, other cognitive and behavioral(More)
STUDY OBJECTIVES To comprehensively review research on the association between childhood sleep-disordered breathing (SDB) and neurobehavioral functioning. DESIGN Qualitative and quantitative literature review. SETTING N/A. PATIENTS OR PARTICIPANTS N/A. INTERVENTIONS N/A. MEASUREMENTS AND RESULTS The findings of 61 studies of the relationship(More)
STUDY OBJECTIVES The research literature on the neuropsychological effects of obstructive sleep apnea (OSA) has yielded seemingly contradictory findings, and narrative reviews of this literature are prone to interpretive errors. We used sophisticated meta-analytic models to minimize such errors, with the goal of clarifying the effect of OSA on(More)
PURPOSE Clinicians often assume that children with posterior fossa tumors are at minimal risk for cognitive or adaptive deficits if they do not undergo cranial irradiation. However, small case series have called that assumption into question, and have also suggested that nonirradiated cerebellar tumors can cause location-specific cognitive and adaptive(More)
BACKGROUND The relationship between inadequate sleep and mood has been well-established in adults and is supported primarily by correlational data in younger populations. Given that adolescents often experience shortened sleep on school nights, we sought to better understand the effect of experimentally induced chronic sleep restriction on adolescents' mood(More)
BACKGROUND Adenotonsillectomy is commonly performed in children with the obstructive sleep apnea syndrome, yet its usefulness in reducing symptoms and improving cognition, behavior, quality of life, and polysomnographic findings has not been rigorously evaluated. We hypothesized that, in children with the obstructive sleep apnea syndrome without prolonged(More)
STUDY OBJECTIVES (1) to determine the associations of sleep disordered breathing (SDB) with behavioral functioning, cognitive test scores, and school grades during middle- to late-childhood, an under-researched developmental period in the SDB literature, and (2) to clarify whether associations between SDB and school grades are mediated by deficits in(More)
The diagnostic criteria for Angelman syndrome includes sleep disturbance as an associated characteristic. There are, however, few researchers who have examined sleep problems in this population. Our goal in this study was to better characterize the sleep patterns and problems in individuals with Angelman syndrome. Parents of 339 individuals between the ages(More)
This review seeks to familiarize clinicians with several major theoretical perspectives on the relationship between bulimia nervosa and depression. It begins by clarifying the affective changes which occur within the binge-purge cycle. Six hypotheses relating negative affect to bulimia nervosa are then reviewed in light of these changes, with their(More)
