Introduction: Attention-Deficit/Hyperactivity Disorder (ADHD)

Topic 1: Attention-Deficit/Hyperactivity Disorder (ADHD)

Attention-Deficit/Hyperactivity Disorder (ADHD) is a neurodevelopmental (brain-based) disorder. It is characterized by an on-going pattern of inattention and/or hyperactivity-impulsivity. This is present across multiple settings, such as work and home. Many of the symptoms can look like extreme forms of normal behavior, and lead to significant challenges in daily life.

Although ADHD begins in childhood, it carries through to adulthood approximately 50% to 60% of the time. You may primarily experience symptoms related to inattentiveness, or primarily to hyperactivity/impulsivity. You may also experience symptoms from both categories (inattentiveness and hyperactivity/impulsivity). Symptoms can be mild, moderate or severe.
