global developmental delay
Significant delays in two or more developmental domains including motor, language, cognitive, social, or adaptive functioning.
Full Definition
Global developmental delay (GDD) is a clinical term used to describe children under age 5 who demonstrate significant delays in two or more of the following developmental domains: gross or fine motor skills, speech and language, cognition, social and personal development, and activities of daily living. The diagnosis requires delays of at least two standard deviations below the mean in standardized developmental assessments. GDD often serves as a provisional diagnosis for young children who may later receive more specific diagnoses such as intellectual disability when formal cognitive testing becomes feasible. Children with GDD typically require comprehensive medical evaluation to identify underlying causes and benefit from early intervention services and multidisciplinary therapeutic support to maximize developmental potential.
Usage
Usage note: Used for children under 5; specify which developmental domains are affected and degree of delay.
