Attention-deficit/hyperactivity disorder (ADHD) is increasingly recognized as a lifespan neurodevelopmental condition that persists into adulthood in a substantial proportion of individuals. Despite growing awareness, adult ADHD is frequently underrecognized, particularly in those with high intellectual ability and sustained academic or professional success. Misconceptions that high achievement without external supports excludes ADHD can delay diagnosis. This case describes a physician in his 30s with lifelong inattentive symptoms and inefficiency, who excelled in patient care yet struggled with selective task organization and completion. Years earlier, his difficulties were attributed to depression, likely influenced by the demands of medical training. When attentional symptoms persisted and began to affect personal relationships, he underwent a comprehensive neuropsychological evaluation. Testing revealed selective attentional and executive functioning vulnerabilities consistent with ADHD, Predominantly Inattentive Presentation. Depressive symptoms, including guilt and self-blame, were secondary to repeated lapses in attention and incomplete task follow-through. Receiving a formal ADHD diagnosis was profoundly clarifying, allowing the patient to pursue targeted interventions and better understand the relationship between chronic inefficiencies and self-perception. This case illustrates the value of neuropsychological assessment in clarifying diagnosis when achievement history may mask symptoms or when depressive features appear prominent. Recognition of ADHD in high-functioning adults has implications for timely intervention, self-awareness, and optimization of personal and professional functioning.
