Neurobehavioral implications of habitual snoring in children.

Objective: Current guidelines for the treatment of children with obstructive sleep apnea (OSA) suggest that primary snoring (PS) in children is benign. However, PS has not been well evaluated, and it is unknown whether PS is associated with serious morbidity. This study investigated whether PS is associated with neurobehavioral deficits in children.

Neurobehavioral correlates of sleep-disordered breathing in children.

The effects of sleep-disordered breathing (SDB) on neurobehavioral function were examined in two matched groups of children from the general population. Thirty-five children with polysomnographically confirmed SDB were matched for ethnicity, age, gender, maternal educational attainment, and maternal smoking, to healthy children with no evidence of SDB. Children with SDB had significantly lower mean scores on the Differential Ability Scales for General Conceptual Ability (similar to IQ) and for the Non-verbal Cluster.

The effect of stimulants on sleep characteristics in children with attention deficit/hyperactivity disorder.

Objective: To investigate the effects of stimulant medications on subjective and objective sleep characteristics of children with attention deficit/hyperactivity disorder (ADHD) compared with control children.

Methods: An observational study in the sleep clinic and the community. Children with characteristics of ADHD, both stimulant-medicated (n=53), and non-medicated (n=34), together with control children (n=53) completed a sleep habits questionnaire prior to undergoing full overnight polysomnographic assessment.

Sleep disturbances in children with attention deficit hyperactivity disorder.

The objective of the study was to compare polysomnographic patterns in two groups of preadolescent children with attention deficit hyperactivity disorder (ADHD) (a sleep clinic referral sample and a community sample) with control children. A prospective and observational study in the sleep clinic and the community was undertaken. Forty-seven ADHD children referred to the sleep clinic (ADHDcl), 53 ADHD children from a community survey (ADHDcom), and 49 control children underwent overnight polysomnography.

Sleep and neurobehavioral characteristics of 5- to 7-year-old children with parentally reported symptoms of attention-deficit/hyperactivity disorder.

Objectives: This study examined the hypothesis that domains of neurobehavioral function would be selectively affected by sleep-disordered breathing (SDB). Therefore, we assessed potential relationships between objectively measured sleep disturbances and neurobehavioral function in children with reported symptoms of attention-deficit/hyperactivity disorder (ADHD) and also determined the incidence of snoring and other sleep problems in 5- to 7-year-old children in the local community and potential relationships to parental snoring and passive smoking.

Methods: Parents of 5- to 7-year-old children in public schools were surveyed about their child's sleeping habits using a validated questionnaire.
