The Australian Conference on Neurodevelopmental Disorders* covers the group of conditions with onset in the developmental period, typically manifesting early in development before a child enters school. The range of developmental impacts varies from very specific limitations of learning or control of executive functions to global impairments of social skills or intelligence. These disorders frequently co-occur; for example individuals with autism spectrum disorder often receive a diagnosis of attention deficit disorder. Issues with sleep, eating and anxiety can also be common. *Usage of the term Disorders for our conference is intended to align with current DSM-5-TR terminology. The approach of our conference is to highlight "Differences" in neurodevelopment.
