Abstract

Many adult clients have repeatedly asked the authors if the onset of attention-deficit/hyperactivity disorder (ADHD) could happen during the adulthood. The current understanding of the condition of ADHD is that it is a neurodevelopmental disorder whose onset takes place in childhood before the age of 6 years. The triad of impairments in ADHD consists of inattention, hyperactivity and impulsivity. The exact cause of ADHD remains evasive and hence, it is unknown. However, current medical studies have strongly indicated neurogenetic causality pinpointing to its constitutional origin and development impairment of the executive functioning cortex in the brain. In other words, ADHD tends to run in families though environmental factors and lifestyle may worsen or improve the symptoms rather than causing the disorder. In this short paper, the authors have chosen to focus on a case study of a male vicenarian’s ADHD whose onset purportedly happened during his emerging adulthood phase.
