Adult Attention Deficit Hyperactivity Disorder ADHD is a neurodevelopmental condition that affects attention regulation, organisation, emotional control, and impulse management across daily life. It is best understood as a difficulty with executive functioning, which includes planning, prioritising, remembering tasks, managing time, and regulating emotional responses. In adults, ADHD often presents as mental restlessness, overwhelm, inconsistent performance, and difficulty following through rather than visible hyperactivity. ADHD begins in childhood even when it is only recognised later in adult life, and diagnosis is based on established clinical criteria (American Psychiatric Association, 2013; Barkley, 2015).
