ADHD is a relatively common group of psychological disorders that occur in childhood (mostly around the age of 3) and manifests itself as a more pronounced group of syndromes with difficulty concentrating attention, short attention spans, and excessive or impulsive activity compared to children of the same age. Two characteristics are evident in children with ADHD: one is attention impairment, which is manifested by an early departure of attention before something is done; the second is hyperactivity, which is manifested by excessive restlessness, especially in environments that require relative quiet. In the case of a child who is attending school, this may include: dawdling on homework, losing things, not being able to keep quiet in class, making small movements, sometimes getting out of their seats to do some “private work”, often clashing with classmates due to lack of discipline, and teachers often having to find parents “in trouble”. “The teacher often has to find trouble with the parents. ADHD is a common childhood psychological disorder with a prevalence of about 5% among school-age children, and is more common in boys than in girls, about four times as common. Although the condition resolves spontaneously in most children in adulthood, the need for treatment remains strong – ADHD can seriously interfere with a child’s learning. The most common and effective and convenient treatment is medication, with Ritalin being the near-exclusive routine. Psychotherapy, especially family therapy, is also an effective treatment, especially for cases where there is reluctance to take medication or concern about its side effects.
