Here’s a new study which reinforces what I’ve been saying about sleep-breathing problems and children: That it’s a major undiagnosed cause of developmental and behavior problems in childhood. Researchers from Albert Einstein College of medicine followed over 11,000 children over a 6 year period. Parents were asked about snoring in sleep surveys from 6 months on, and at 7 years, they filled out a behavioral assessment. Not too surprisingly, children who snored as early as 6 months of age had a 50% increased risk of developing behavior problems by age 7 compared to controls.
We know that children who are sleep deprived become paradoxically hyperactive. In contrast, adults get sleepy (there are always exceptions to this observation). This study supports another study which I mentioned in the past showing that in children with ADHD who undergo tonsillectomy, about 50% can be cured for their ADHD condition. It’s no wonder that stimulants like Ritalin can help to calm a hyperactive child.
It’s important to note that I’m not saying all cases of ADHD are due to sleep-breathing disorders. However, it’s been estimated that a significant number of children (25 to 50%) with an ADHD diagnosis could have a treatable sleep-breathing problem. With these numbers in mind, wouldn’t it make sense to routinely screen for obstructive sleep apnea or a sleep-breathing problem before being given an ADHD diagnosis?
