Attention Deficit Hyperactivity Disorder (AD/HD) is a neurodevelopmental condition characterised by a persistent pattern of inattention and/or hyperactivity-impulsivity that interferes with development and everyday functioning.

Inattention

Difficulties sustaining attention, organising, and retaining information. This may include memory difficulties, challenges following instructions, managing sequential tasks (planning), and getting easily distracted.

Hyperactivity and Impulsivity

Constant fidgeting, inability to remain seated, being described as 'driven by a motor', excessive talk, blurting out answers, interrupting and intruding on others.

Shared characteristics

For both autism and ADHD, characteristics need to be present across multiple settings and in the early developmental period. They may become more evident when specific life demands commence — for example starting nursery, primary school, or when social and performance demands increase.
