The final exams were over, Xiao Ke came home with his head pulled back and handed his mom the report card in tears, “Mom, I did my best, but I still failed.” Mom hugged Xiao Ke, also frowned tightly. Thinking back to the parent-teacher conference, the teacher told Xiao Ke’s mom that Xiao Ke was always inattentive and absent-minded in class, and that he could not finish his classroom homework on time because he would write for a while and play for a while. He was also careless, losing stationery and books, and often misreading and forgetting questions on tests. The teacher repeatedly called Xiao Ke to the office to enlighten and educate him, and his mother often criticized him and helped him, but Xiao Ke did not make any progress as usual. The teacher and his mother were so frustrated by Xiao Ke that they gradually lost their confidence and patience with him. Xiao Ke is also very aggrieved: I would like to follow the teacher and mom’s requirements to do, but I can not control myself, academic performance is always up, is my brain than others stupid? Many children with learning difficulties are in the same situation as Xiao Ke. Is it because of their low intelligence or bad behavior that they are difficult to discipline? In fact, what brings them and their parents distress is a common childhood disease —- Attention Deficit Hyperactivity Disorder (ADHD), the prevalence rate of school-age children is about 3%-10%, the incidence rate of boys is three times as high as that of girls. Children with ADHD have normal intelligence, and some are very bright, and it is not due to problems with moral character or simply poor parenting. The reason is that certain neurotransmitters in the brain are abnormal, causing brain dysfunction, and about 70-85% of children with ADHD have learning difficulties. These children have difficulty concentrating, do not pay attention in class, can not fully grasp the content of the study, in addition, they have poor self-control, hyperactivity, lack of patience and perseverance in learning, it is difficult to go deeper, do homework carelessly, sloppy scribbling, play while doing, and do not answer the exam seriously, often look at the wrong questions, missed questions, thus seriously affecting the academic performance. Highlighted as a grasp of academic performance on the grasp on the up, do not grasp the results on the decline, on and off, fluctuating greatly. Elementary school in the lower grades, due to homework is simpler, the child’s intellectual level and other factors make learning difficulties is not obvious, but in the long run, with the increase in learning content and difficulty, the child’s grades will deteriorate, and even the phenomenon of failing or repeating a grade. Long-term poor academic performance, parents and teachers will blame the child’s self-evaluation will be reduced, lack of self-confidence, loss of interest in learning, anorexia, anxiety, depression, oppositional defiance and other psychological and behavioral disorders, seriously affecting the child’s healthy growth. One Monday morning, his mother brought Xiao Ke to the Children’s Behavioral and Psychological Clinic of Boai Hospital in Zhongshan City, where Dr. Deng Cheng made the diagnosis of ADHD after inquiring about Xiao Ke’s condition in detail and giving him a systematic and comprehensive examination. After learning about ADHD, his mother accepted the doctor’s recommendation of behavioral therapy and medication. After the standardized treatment, Xiao Ke’s ability to listen to class and complete homework soon improved significantly, and his test scores also improved significantly. Two months later, Xiao Ke went from being the tail of the class to being one of the top students in the class. Parents, teachers and classmates all felt that Xiao Ke seemed like a new person. For most children with ADHD, standardized comprehensive treatment can improve their symptoms significantly, keep their attention, listen attentively in class, think quickly, make progress in learning, improve their grades, and make the children’s potential intelligence fully developed.
