A study in the April issue of SLEEP found that children with sleep apnea have a higher risk of behavioral, adaptive and learning problems.  Sleep-disordered breathing doubled and tripled the odds of threshold scores on most assessments, reported MedPage Today.  Children with persistent sleep apnea also were seven times more likely to have parent-reported learning problems and three times more likely to have school grades of C or lower, noted UPI.  The findings also were mentioned by FOX news broadcasts in Colorado Springs, Fargo and Fresno.
