Attention-Deficit/Hyperactivity Disorder (ADHD)

Attention deficit/hyperactivity disorder is a neurobehavioural disorder of concentration, focus, activity and impulsivity. Sub-types of the disorder described in DSM-V are categorized as being predominantly inattentive, predominantly hyperactive-impulsive or the two combined. Symptoms emerge before the age of seven, and 30-50% of those individuals diagnosed in childhood continue to have symptoms into adulthood.
