ADHD (Attention Deficit Hyperactivity Disorder) is a neurodevelopmental disorder which is the most prevalent childhood psychiatric disorder in Canada. Symptoms continue into adulthood in more than 75% of people. It is recognized by medical associations and government health agencies as a medical disorder and is not caused by parenting. A person with ADHD has differences in brain development that can include difficulties with paying attention, sitting still and controlling impulsive behaviour. Although everyone can have trouble with these things at times, in ADHD these difficulties are so persistent and pervasive that they affect every day functioning at home, school or work and in the community.
