Dr David McIntoshthank you for this useful explanation connecting sleep disordered breathing and ADHD to research findings 🙌🏻🙏🏻
Can treating sleep-disordered breathing improve ADHD-like symptoms in children?
Yes—but we need to be precise about what the evidence actually shows.
Children with sleep-disordered breathing (SDB) can develop symptoms that overlap with ADHD, including:
• Inattention
• Hyperactivity
• Impulsivity
• Irritability
• Poor concentration
• Emotional dysregulation
So what happens when the underlying sleep-disordered breathing is treated?
One of the most important studies in this area was the Childhood Adenotonsillectomy Trial (CHAT).
The study randomised 464 children with obstructive sleep apnoea to early adenotonsillectomy or watchful waiting.
Surgery produced significantly greater improvements in:
• Behaviour
• Sleep-related symptoms
• Quality of life
• Polysomnographic findings
But there was not a statistically significant improvement in the primary objective measure of attention and executive function.

This distinction is important.
It would be incorrect to say:
“Adenotonsillectomy treats ADHD.”
The evidence does not support that statement.
But it is equally inappropriate to ignore the possibility that untreated sleep-disordered breathing can contribute to behavioural and attentional difficulties.
A 2026 systematic review and meta-analysis found moderate improvement in parent-reported behavioural measures and a smaller improvement in executive function following adenotonsillectomy, while objective ADHD-related measures did not reach statistical significance.

So perhaps the better clinical question is
“Does this child have ADHD, sleep-disordered breathing, or both?”
Because if a child has an underlying sleep disorder, treating the sleep disorder may improve some of the behaviours that brought the child to medical attention in the first place.
And that can be a very meaningful outcome—even if the child still meets criteria for ADHD.
We need to be asking:
“How well is this child actually sleeping?”
