Attention Deficit Hyperactivity Disorder (ADHD), formerly known as childhood hyperactivity disorder, is a group of syndromes that are characterized by significant difficulty concentrating, short attention span, hyperactivity and impulsivity compared to children of the same age. In layman’s terms, ADHD is mainly characterized by symptoms of inattention and hyperactivity. Because of the relatively high prevalence rate of 4.31% to 5.83%, ADHD has become an important public health problem today. Inattentiveness not only affects children’s schooling, but also reduces their self-confidence, affects their interaction with people and society around them, and is extremely detrimental to their physical and mental development. Because of its insidious onset, ADHD is often not taken seriously in its early stages and often receives parental attention only after school because it affects school. In fact, if detected early, early treatment can improve the educational and psychosocial development of most children with ADHD. The diagnosis of ADHD is mainly symptomatic after excluding other organic diseases. The diagnosis requires a parent interview, a child interview, necessary psychological evaluation and laboratory tests. Through behavioral interventions and medication, children with ADHD are able to improve not only their academic performance, but also their self-confidence.
