Why this study was done

Polysomnography (PSG) is the main test used to diagnose sleep problems in children. However, it can be difficult for children to tolerate all the sensors needed for the test. Little was known about how children with neurodevelopmental disorders (NDD) cope with PSG compared to children without NDD.

What the study did

Researchers looked back at PSG tests performed over six months at Queensland Children’s Hospital. They compared how well 132 children with NDD and 139 neurotypical children tolerated the test and its sensors, using reports from sleep technicians and doctors.

What the study found

• Children with NDD were more than three times as likely to have trouble with PSG sensors.
• Nasal prongs and thermistors (used to measure airflow) were the hardest sensors for all children.
• Children with Down syndrome had the most difficulty tolerating the test.

What this means

PSG can be particularly challenging for children with NDD, especially those with Down syndrome. Strategies like desensitisation programs or alternative testing methods may help improve the experience and make sleep assessments more effective for this group.
