  2. Definition

    Attention-Deficit hyperactivity disorder (ADHD) is a neurodevelopmental condition with secondary behavioural, social, and educational difficulties. ADHD is defined as a behavioural syndrome characterized by the core symptoms of hyperactivity, impulsivity, and inattention which can lead to psychological, social, education, or occupational impairment. The ADHD phenotype includes hyperkinetic disorder, hyperkinetic conduct disorder, attention-deficit hyperactivity disorder and disturbance of activity and attention.

    ICD-10 definition

    This definition has been previously validated and published (John et al, 2022; Martin et al, 2024).

    Read codes definition

    This definition also includes disturbance of activity and attention, attention deficit with/without hyperactivity, and ADHD treatment, management and monitoring. This definition has been previously validated and published (John et al, 2022; Martin et al, 2024).

    SNOMED CT definition

    This definition has been created by mapping the existing Read code and ICD-10 definitions and additional exploration of SNOMED CT codes. It excludes non-specific definitions of neurodevelopmental disorders, developmental delay, attentional delay and measurement codes for ADHD medication/prescription.

    An auxiliary concept “ADHD assessments” is provided to help identify individuals being assessed for ADHD.

    Warning: The SNOMED CT definition have not undergone validation yet.
