Deciding whether someone has ADHD requires careful assessment and determination by a specialist, usually a paediatrician or psychiatrist, and is based on extensive data of developmental, learning, social and behavioural areas, drawn from a range of sources. The parent’s input is critical for an accurate diagnosis.
For a diagnosis of ADHD, some symptoms must have been present before 7 years of age. They have to present in more than one environment (eg at home and school) and be inappropriate for the age of the child and the setting.
Tests which can be used include psychological tests such as the WISC_R and the Connors Rating Scale.
