Global Developmental Delay
A diagnosis given to young children who show significant delays in two or more developmental domains, when standardized testing is not yet feasible.
Overview
Global developmental delay is diagnosed in children under age five who fail to meet expected developmental milestones in two or more domains, such as motor, language, cognitive, or social skills, used when a child is too young for standardized cognitive testing.
Signs and Symptoms
Symptoms can include delayed walking, talking, or other milestones relative to same-age peers, across more than one developmental area. Experiencing one or more of these symptoms does not necessarily mean that a person has this condition. Diagnosis requires an appropriate clinical evaluation.
Causes and Risk Factors
Causes can include genetic conditions, prenatal exposures, birth complications, or early illness or injury; in many cases, the exact cause is not identified at the time of diagnosis.
Diagnosis
A diagnosis should be made by a qualified healthcare professional following a comprehensive clinical assessment. Clinicians may use established diagnostic frameworks such as DSM-5-TR and/or ICD-11 as part of a comprehensive assessment.
Treatment
Treatment depends on the individual’s symptoms, clinical history, severity, age, co-occurring conditions, and other relevant factors.
Psychotherapy
Early intervention services, including physical, occupational, and speech therapy, have strong evidence supporting their use.
Living With Global Developmental Delay
Early, consistent engagement with developmental intervention services is associated with better long-term outcomes.
When to Seek Professional Help
Professional evaluation may be appropriate if symptoms persist, worsen, cause significant distress, or interfere with work, school, or relationships.
Outlook
Outcomes vary widely; some children catch up to peers with early intervention, while others go on to receive a more specific diagnosis, such as intellectual disability, as they get older.
