ADHD refers to a group of symptoms which begin in early childhood and continue into adulthood causing difficulty at home, school and at work. It is the most common behavioural disorder of children and teens. Children or adults suffering from ADHD are restless, hyperactive, impatient, impulsive and inattentive. Boys are diagnosed with ADHD more often than girls. We frequently get little ones, moving around in the chamber, touching different things on the table, opening drawers, not listening to their parents or to the doctor, adults of this disorder can not wait for their turn, they are impatient, all the time enquiring, how long they will have to wait, constantly moving in and out of the waiting room.
