Attention-deficit hyperactivity disorder in children and adolescents: assessment and treatment

Attention-deficit hyperactivity disorder (ADHD) is a heterogeneous neurobehavioural syndrome, complex in aetiology and presentation. It is characterised by symptoms of inattention, hyperactivity and impulsivity of varying combinations and degrees of severity. This article seeks to elucidate the different components of the assessment and diagnosis of ADHD in comparison with various differential diagnoses that must also be considered. Despite its complexities, ADHD can be effectively managed using a comprehensive approach advocated by the National Institute for Health and Care Excellence (NICE). The article discusses the combination of medication, psychoeducation and parental handling that has been shown to be effective in containing the problematic symptoms of ADHD. It also highlights the difficulties that can persist into adulthood and potential strategies to improve prognosis.
