An ADHD assessment is a comprehensive process that evaluates whether an individual meets the criteria for Attention-Deficit/Hyperactivity Disorder (ADHD). This assessment involves multiple steps, including clinical interviews, standardized questionnaires, cognitive testing, behavioral observations, and sometimes collateral information from family, teachers, or colleagues. The goal is to determine whether ADHD symptoms are present, how they impact daily life, and whether other conditions may be contributing to the difficulties.
