Assessing children and youth with global developmental delay and intellectual developmental disorder.

Abstract

The paediatric health care provider (HCP) plays a pivotal role in the care of children with global developmental delay (GDD) and intellectual developmental disorder (IDD). This role encompasses early detection of developmental concerns, guiding families through the diagnostic process, coordinating care with other HCPs and educators, and ensuring that appropriate interventions are accessed. A comprehensive review of the medical history, completion of a thorough physical assessment, and the initiation of a genomic investigation-depending on clinical indications and available resources-are the mainstays for assessing children with GDD/IDD. Metabolic testing is only recommended in specific circumstances, which are briefly described.
