Childhood ADHD is medically known as attention deficit hyperactivity disorder syndrome (ADHD) in children. The disorder is characterized by inattention, hyperactivity, emotional impulsivity, learning difficulties, and disruptive behavior. There are two types of attention, one is active attention, which means that the person focuses his or her energy on something according to his or her subjective will in order to achieve a certain goal or accomplish a certain task. Active attention requires will and perseverance. It is often called “effort”. The other type of passive attention is when objective things attract attention by their own characteristics, so that people can turn and focus their attention on them at will and without effort. Children with ADHD are characterized by a deficit of active attention and a relative hyperactivity of passive attention. This often manifests itself in the short time that they are able to focus on the lesson in class. The child’s mind may wander, and he or she may not be able to respond to the teacher’s questions. Easily distracted by extraneous external stimuli when doing homework. A little bit of homework takes most times longer to complete than normal children, despite repeated prodding. Even so, their work is sloppy and error-prone. Usually forgetfulness (lack of active attention). They may pay full attention to interesting TV programs, books and computer games or pay relatively close attention to them (passive attention hyperactivity). The pathology of ADHD is based on poorly developed or impaired function of the frontal and subcortical structures of the brain. The basic problem is the impairment of higher level active attention in the cerebral cortex and the relative enhancement of lower level passive attention. Hyperactive behavior is a manifestation of self-stimulation by the body to maintain an under-awake cerebral cortex. The current treatment of ADHD mainly relies on medication, supplemented by psychotherapy and behavioral training. The most commonly used drugs are central stimulants to increase the excitability of the under-awake cerebral cortex. The most commonly used drug is Quaaludes, also known as Ritalin. It can be stopped on double days and holidays. After taking the drug, firstly, active attention is enhanced and improved, when children can sit quietly in their seats during class, concentrate on the teacher and are not easily influenced by external stimuli. Secondly, the amount of activity and small movements can be reduced, the irrelevant activities that were carried out in class disappear, the effective listening time increases, and therefore, the academic performance improves, and some children even have immediate effects after taking the drug …… These are the main reasons why central psychostimulants are popular in children with ADHD These are the main reasons why central psychostimulants are so popular among children with ADHD. Not all children diagnosed with ADHD need to take stimulants; 2. The need to continue to take stimulants should be based on the efficacy, if the efficacy is satisfactory, after more than 3 months of maintenance can be reduced or discontinued for observation; 3. The belief that children with ADHD will naturally disappear as they get older and refuse to take stimulants to avoid “brain damage” is incorrect. Since ADHD can hinder mental and physical development, affect learning, cause low self-esteem and conduct disorders, and its adverse consequences are difficult to compensate, so we must weigh the pros and cons. Regarding the prognosis of ADHD, it is currently believed that only 1/3 of children enter adolescence or adulthood with behavioral symptoms that disappear, and most patients still have attention deficits, impulsivity, and social interaction problems. However, in adulthood, most patients are no longer in the classroom, so behavioral symptoms are less pronounced than before, giving the false impression that symptoms disappear with age. In addition, when we mention ADHD, we often overemphasize its negative impact on learning. In fact, ADHD patients have their strengths in job hunting because of their high energy and active personality traits, which make them suitable for careers in sales, software design, stock management, art, etc. This is where ADHD patients have their strengths.
