Laboratory polysomnography is the gold standard for objective sleep measurement. With hospital waiting times becoming increasingly long, outpatient polysomnography seems a good solution. Children are at greater risk of developing sleep disorders and polysomnography in the hospital laboratory can be a stressful examination for these children and their parents. This can be even more the case in populations of children with neurodevelopmental disorders, such as Attention Deficit Disorder with or without Hyperactivity (ADHD), or dys- learning disorders. Several studies have already demonstrated the feasibility of ambulatory, in a home setting, polysomnography in children. The objective of this study is to demonstrate the acceptability and satisfaction of performing polysomnography at home on a large cohort of children, including children with neurodevelopmental disorders.

Inclusion Criteria:

• All consecutive children who underwent a H-PSH
• Age beetween 2 and 17 years old

Exclusion Criteria:

• No signed informed consent form for study participation

The study population consisted of any children coming to the doctor's office for a home unattended polysomnography, aged between 2 and 17 years at the time of polysomnography, and whose parents had signed a consent form for polysomnography and data collection.

Observational study on routine practice. The individual data collected are specific to the protocol and cannot be directly reused without the full set of tools and methodologies developed for this study. Their dissemination could be misinterpreted or non-reproducible outside this context.
