Welcome to ADHD & ADD Awareness

Attention-Deficit Hyperactivity Disorder (ADHD) and Attention Deficit Disorder (ADD) are neurodevelopmental disorders that significantly impact the regulation of attention, impulse control, and executive functioning. These conditions affect millions of people worldwide — from children in classrooms to adults in the workplace.

ADHD ranks among the most widely researched childhood mental health issues globally. It is estimated that nearly 5 to 7 percent of children and about 2.5 percent of adults are affected. The disorder is often identified in childhood but continues to impact individuals throughout adolescence and adulthood, affecting academic success, professional effectiveness, and interpersonal relationships.

Historically, ADD was a term used to describe individuals who showed typical inattentional symptoms without hyperactivity. Today, modern diagnostic systems — including the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) — classify ADD as a subtype of ADHD known as the Predominantly Inattentive Presentation.
