developmental regression
Loss of previously acquired developmental skills, indicating potential neurological or metabolic disorders.
Full Definition
The loss of developmental skills or abilities that were previously mastered, representing a concerning sign that may indicate neurodegenerative conditions, metabolic disorders, or severe developmental disorders like autism spectrum disorder. Regression can affect language, motor skills, social abilities, or cognitive function and typically prompts urgent evaluation. The timing, pattern, and extent of regression help guide diagnostic workup and intervention planning. Documentation must clearly distinguish true regression from developmental plateaus.
