The National Institute for Health and Clinical Excellence (NICE) and the National Collaborating Centre for Mental Health have issued a clinical guideline on the diagnosis and management of attention deficit hyperactivity disorder (ADHD) in children, young people and adults.

Key recommendations from the guideline include (taken directly from source):
• Trusts should ensure that specialist ADHD teams for children, young people and adults jointly develop age-appropriate training programmes for the diagnosis and management of ADHD for professionals who have contact with people with ADHD.
• Parent-training/education programmes should be offered as first line treatment of ADHD. Healthcare professionals should offer parents or carers of pre-school children with ADHD a referral to a parent-training/education programme as the first-line treatment.
• Teachers who have received training about ADHD and its management should provide behavioural interventions in the classroom to help children and young people with ADHD.
• If the child or young person with ADHD has moderate levels of impairment, the parents or carers should be offered referral to a group parent-training/education programme, either on its own or together with a group treatment programme (cognitive behavioural therapy [CBT] and/or social skills training) for the child or young person.
• In school-age children and young people with severe ADHD, drug treatment should be offered as the first-line treatment. Parents should also be offered a group-based parent-training/education programme.
• Drug treatment for children and young people with ADHD should always form part of a comprehensive treatment plan that includes psychological, behavioural and educational advice and interventions.
• Drug treatment for adults with ADHD should always form part of a comprehensive treatment programme that addresses psychological, behavioural and educational or occupational needs.
