[Summary of the Dutch College of General Practitioners' (NHG) practice guideline 'ADHD in children'].

The diagnosis of ADHD may be considered if a child is hyperactive, impulsive or inattentive, and if this behaviour results in evidently impaired functioning in multiple settings. Children with behavioural problems and slightly impaired functioning may benefit from patient information, education and parenting advice. From the age of 6 years, children can be offered diagnostic testing and professional support within the primary care setting, provided sufficient knowledge and expertise is available and there is collaboration with other health care providers. Management of a child with ADHD but no comorbid psychiatric disorder, consists of a step-by-step plan including education, parent and teacher guidance and, optionally, behavioural therapy for the child. In consultation with parents, child and other therapists, methylphenidate can be prescribed if behavioural interventions are not sufficiently effective. Children taking medication for ADHD should be monitored periodically, including assessment of the effectiveness and side effects.
