developmental delay
Significant lag in achieving expected developmental milestones for a child's chronological age.
Full Definition
Developmental delay refers to a significant lag in a child's achievement of developmental milestones in one or more areas including gross motor, fine motor, language, cognitive, or social-emotional development. A delay is typically defined as performance more than 2 standard deviations below the mean for age or failure to achieve milestones within the expected timeframe. Early identification of developmental delays is crucial as early intervention services can significantly improve long-term outcomes. Documentation requires specific details about affected domains, severity of delay, and referral for appropriate therapeutic services.
Usage
Usage note: Specify affected developmental domains and severity; distinguish from regression.
