There is a difference between ADHD, which is a disorder, and hyperactivity, which is a normal child. Children with ADHD often have brain developmental disorders and develop more slowly, both structurally and functionally, as opposed to normal children. Mental manifestations are inattention, mental hyperactivity, poor academic performance, great difficulty in doing tasks, especially longer ones, agitation, impulsivity and these phenomena, and some patients can have emotional symptoms. These symptoms begin to appear in childhood and continue into adulthood with significant symptoms. Those with a clear diagnosis can be treated with medication as well as psycho-behavioral therapy. The common medical treatments are central excitatory drugs and non-central excitatory drugs. Children with hyperactivity are more active, do not have central nervous system developmental disorders, do not have learning disabilities, do not have attention disorders or impulse disorders, and have stronger organizational and executive skills. This behavior can often be overcome by persuasion and education, and can be controlled by the child.
