How is ADHD clinically assessed?

When evaluating individuals for attention-deficit hyperactivity disorder (ADHD), or hyperkinetic disorder (HKD), it is typical to use multiple stages of assessment prior to formal diagnosis.1-5 Following assessment, formal diagnosis is based on symptomatology and conducted by secondary care specialists using validated medical classification systems (e.g. the Diagnostic and Statistical Manual of Mental Disorders – 5th Edition [DSM-5TM] or the International Classification of Diseases 11th Revision [ICD-11]).6,7

Assessment of ADHD typically involves the comprehensive evaluation of information gathered from a number of sources, including parents/carers, family members, teachers, or partners and colleagues, depending on the age of the individual (Figure 1).1-5 A range of qualified healthcare professionals may be involved in the assessment and diagnosis of ADHD, such as psychiatrists, psychologists or nurses, who have training and expertise in the diagnosis of ADHD in children, adolescents and/or adults.1-4

What clinical examinations can be performed?

Clinical examination aims to identify the presence of other illnesses with symptoms that overlap with those of ADHD.1-5

  • This clinical examination typically involves inspections for vision or hearing impairments, neurodevelopmental immaturity in relation to gross and fine motor functions and motor or vocal tics, and retardation.
  • A general examination of the individual’s physical health may also be performed to highlight any evidence of a congenital disorder.
  • Clinicians may also look for evidence of psychiatric comorbidities, which are often found in individuals with ADHD.

Why are observations useful?

Behavioural observations may be useful to confirm symptoms reported in an interview.1,8 For children and adolescents, parent rating scales and teachers in particular may be especially well placed to identify symptoms of ADHD.8 Reports from teachers are recognised as one of the optimal sources of information related to problems with behaviour, developmental or social functioning in children and adolescents, with standardised questionnaires considered a useful tool to obtain such information.8 Classroom observations by an educational psychologist are also useful for diagnosing children and adolescents, if feasible.2

What rating scales are available?

A number of rating scales are available to help assess general behaviour and psychosocial functioning, ADHD symptomatology and comorbidities.1-5 Rating scales can be completed by parents, teachers or the individual themselves, depending on which scale is chosen, and are considered to be an essential part of the full assessment process for ADHD.1-4

 

Information collected from family members and a spouse is useful for the lifetime assessment of adults with ADHD.5
