With school starting, more parents are coming to the psychological clinic for counseling. Recently, I met two such cases when I was sitting in the clinic, and Ms. A, a strong woman in the office, was busy with her work all day. When her child was 3 years old, she divorced her husband peacefully due to the appearance of a third party, and had to leave her child in the countryside to be taken care of by her parents. For several years, Ms. A felt that she owed the child too much, and this year, at the age of 7, she specially brought the child to school in the city. But within a few days of school, the teacher reflected to her that the child’s small movements in class, buttocks twisting on the bench, the books are not painted like. He likes to provoke others and often argues and fights with his classmates. She often misses homework assignments because she cannot hear them. She reads “6” as “9” and “d” as “b”, and always has trouble distinguishing between left and right. Her teacher suggested that she bring her child to our hospital for treatment. Her teacher suggested that she bring her child to our hospital for treatment, and her child was found to have ADHD. The disease is also known as “attention deficit disorder” or “mild brain dysfunction”, which mostly starts before the age of 7, with hyperactivity as the external manifestation, mainly characterized by inattention and difficulty in retention, accompanied by mood changes and learning disabilities. The Chinese Classification and Diagnostic Criteria for Mental Disorders has the following criteria for determining ADHD: I. The disorder has at least four of the following: easy distraction when learning, hearing any external sound to visit; very inattentive in class, often looking around or dazed; procrastination in doing homework, playing while doing, dirty and messy homework, often doing less or doing it wrong; inattentive to details, often careless in doing homework or other activities He/she loses or does not take care of things; he/she has difficulty in following instructions to complete homework or chores; he/she has difficulty in doing things for a long time; he/she often does not do one thing and then goes to do something else; he/she is often distracted when talking to him/her and seems to listen; he/she loses things in daily activities. Second, hyperactivity disorder at least four of the following: hands or feet often unstable, or squirming when sitting; in the classroom or other occasions requiring the maintenance of seat position; often inappropriate occasions or climbing ladders; play often inappropriate noise, it is difficult to quietly participate in recreational activities; show persistent excessive activity, the social environment or the requirements of others can not make the affected child significantly change; often talk too much; often in often blurts out answers before others have finished asking questions; often fails to line up or wait in order in games or organized situations; and frequently disturbs or interferes with others. Ms. B. is on her second visit to the consultation room. “Doctor, my child is always hyperactive and willful, does he have ADHD?” At present, many parents have many misconceptions about ADHD in children: hyperactivity, impulsiveness, capriciousness that is ADHD; not being able to complete homework well is also ADHD; not listening in class, many times by the teacher looking for parents, fearing that it is ADHD; avoiding responsibility and reducing pressure, some parents not only suspect or even hope that their children are ADHD, so that they can reduce the pressure and responsibility in education, training and correction. Nowadays, there are many only children, parents have higher expectations of their children, and parents are particularly anxious when their children do not learn well. Ms. B’s child was interested in the doctor’s stethoscope as soon as she entered the consultation room, and kept asking the doctor about the stethoscope. He also asked the doctor several times what the parts of the stethoscope did, and even took some of the parts off and used them as toys. This shows that he is still able to concentrate on what he is interested in and is able to come up with ideas. Children with ADHD have a short attention span to stay on one thing and are easily distracted by outside stimuli such as sounds. Clearly, Ms. B’s child is not ADHD. At best, he is a naughty child. Naughty children are punished by “being honest” for a period of time, but not ADHD children, who talk and laugh like nobody’s business just a few minutes after they have been beaten. Children with ADHD must be treated with medication when the symptoms are severe, such as Ritalin and Pemoline, which must be used under the guidance of a doctor because of the adverse effects of these drugs, especially psychiatric dependence. Medication along with behavioral therapy, such as sensory integration training, biofeedback training, etc. can provide better results. Since these children are often discriminated against and have low self-esteem and rebelliousness, their physical and mental development is affected. The attitude of parents and teachers has a great impact on the treatment, so they should give more care to them. Be patient, don’t scold the child, and don’t give up lightly. With the understanding of the disease and the application of various treatment methods, together with a good educational environment, the prognosis of ADHD in children is more optimistic.
