ADHD is a clinical syndrome defined in the DSMIV (APA, 1994) by high levels of hyperactive, impulsive and inattentive behaviours, when they begin during early childhood, are persistent over time, pervasive across situations and lead to clinically significant impairments.The definition of attention-deficit/hyperactivity disorder (ADHD) has been updated in the fifth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) to more accurately characterize the experience of affected adults. This revision is based on nearly two decades of research showing that ADHD, although a disorder that begins in childhood, can continue through adulthood for some people. Previous additions of DSM did not provide appropriate guidance to clinicians in diagnosing adults with the condition. By adapting criteria for adults, DSM-5 aims to ensure that children with ADHD can continue to get care throughout their lives if needed.
