Children afflicted with these conditions appear to share similar problems in sensory modulation but investigational studies on the underlying aetiology are scarce. This scoping review aims to find knowledge gaps, collate hypotheses and to summarise available evidence on the shared pathophysiology of AD, ADHD and ASD in children.Methods and analysis Our study will follow the methodological manual published by the Joanna Briggs Methodology for Scoping Reviews and will be reported in accordance with the Preferred Reporting Items for Systematic reviews and Meta-Analyses Extension for Scoping Reviews. The following electronic databases will be searched for studies focused on children with AD and symptoms of ADHD and/or ASD: Medline ALL via Ovid, Embase, Web of Science Core Collection and the Cochrane Central Register of Controlled Trials via Wiley.Ethics and dissemination This review does not require ethics approval as it will not be conducted with human participants. We will only use published data. Our dissemination strategy includes peer review publication and conference reports.
