The ABC’s of Snoring and Childhood Cognition

Snoring kids can be cute, but snoring may reflect a serious problem. New research in the journal Sleep and Breathing found that primary snoring (PS) is associated with neurocognitive impairments in children.

The community-based study included 1,114 primary school children. The researchers identified 410 children who never snored, and 92 children who habitually snored.

Polysomnogram (PSG) scores distinguished children with PS from those with upper airway resistance syndrome (UARS) or obstructive sleep apnea (OSA). Children with UARS and OSA actually experience pauses in breath that can prevent restorative sleep.

Neurocognitive impairments and poor school performance were compared between children who never snored, those with PS, and those with UARS or OSA.

Of the 92 snorers, 69 had PS while 23 had UARS or OSA.

Compared to children who never snored, children with PS demonstrated significantly more hyperactive and inattentive behavior. They also had a higher risk for poor school performance in mathematics, science and spelling. The risks for PS were on par for children with UARS or OSA.

These results show that children with non-apneic PS may exhibit significant neurocognitive impairments. Consequences may be similar to those associated with UARS or OSA. If confirmed, PS is not “benign” and may require treatment.
