Abstract

Attention deficit hyperactivity disorder (ADHD) has traditionally been viewed as a childhood condition (American Psychiatric Association, 2013). However, research indicates that ADHD persists beyond childhood. Longitudinal studies suggest that approximately 50% to 60% of individuals diagnosed with ADHD in childhood continue to experience symptoms into adulthood (Faraone et al., 2015). This evidence challenges the long-held belief that ADHD is only a paediatric disorder and highlights the need for broader recognition of its manifestations across the lifespan. This article draws on a review of existing longitudinal and cross-sectional studies examining the persistence and transformation of ADHD symptoms from childhood into adulthood. It synthesises empirical findings and theoretical perspectives to illustrate how adult ADHD presents, as well as the social and clinical factors influencing its recognition and diagnosis. Findings suggest that adult ADHD remains underdiagnosed and misunderstood. Many adults develop coping mechanisms that conceal symptoms, or healthcare professionals may overlook the disorder among adults (Murray & Kollins, 2020). Stigma and misconceptions, such as equating ADHD with a lack of self-control or dismissing it as a childhood issue, further complicate diagnosis and treatment. Symptom expression also evolves; hyperactivity tends to diminish and transform into internal restlessness or mental agitation (Kooij et al., 2019), while inattention manifests as difficulties with organisation, planning, and focus (Asherson et al., 2016). Impulsivity may persist through emotional instability, hasty decision-making, or risky behaviours that have social or financial consequences. ADHD should be recognised as a lifelong neurodevelopmental condition rather than as a disorder confined to childhood. Enhanced awareness and diagnostic sensitivity are essential for identifying and supporting adults living with ADHD. Collaboration among healthcare providers, educators, and policymakers is necessary to reduce stigma, improve access to appropriate interventions, and ultimately enhance the quality of life for affected individuals.
