How is global developmental delay diagnosed?

Global Developmental Delay (GDD) is diagnosed through a structured process that includes observation, standardised testing, and medical investigation. In Australia, this is usually managed by a multidisciplinary team before the age of five.

The process may involve:
1. A review of the child's medical and developmental history
2. Observations of delayed milestones in communication, motor skills, cognition, or social interaction
3. Use of standardised tools like the Bayley Scales or Griffiths Developmental Scales
4. Additional tests, which may include:
    • Genetic or chromosomal testing
    • Vision and hearing screening
    • Brain imaging such as MRI

Early diagnosis enables access to NDIS early intervention services.
