Attention deficit hyperactivity disorder (ADHD) is a neurobiological disorder characterized by three core symptoms: the inability to regulate attention; the inability to regulate activity; and difficulty with inhibitory behaviour resulting in impulsivity. ADHD is the most common psychiatric disorder among children and is highly hereditary.1

According to the Centre for ADHD Awareness, Canada, there are up to three children in every school classroom with ADHD. In addition, 80% of adolescents and 60% of adults who experienced childhood ADHD continue to display ADHD symptoms.1
