ADHD is a brain condition in which the levels of neurotransmitters affecting certain centers of the brain are lower than normal. Those diagnosed with
ADHD have trouble with concentration, keeping still and impulsivity. The disorder begins to manifest itself in children between the ages of 5 and 8 and can affect girls and boys. Lack of diagnosis can lead to the symptoms of the condition continuing on into adulthood in a greater number of children.
