What is ADHD (Attention Deficit Hyperactivity Disorder)

The information below cannot be used to diagnose ADHD.  It can only suggest that a person may be a candidate for the disorder.  There are other disorders that have similar signs.  Only an expert in ADHD can diagnose the disorder.  If there is a team with an expertise in ADHD available in your area, please, consult them.  The team may consist of a neurologist, a psychologist, a speech therapist, an occupational therapist and a special needs trained teacher.  Your child’s teacher, your neighbour, your family doctor, your paediatrician cannot diagnose ADHD.  However, your doctor can refer you to an expert or a team of experts.

ADHD is:

A neurological disorder affecting a person’s attention, activity level and impulse control.  This disorder may cause a life-long disability.  However, with proper treatment the effects can “dramatically reduce the family, educational, behavioural and psychological problems experienced by individuals with ADHD” (Sam Goldstein, 2009).  Persons with ADHD are unable to act in the expected manner.  ADHD is only diagnosed if it interferes with the person’s quality of life and is present for a prolonged period of time.
