In the child health clinic, there are often children whose mothers say, “Doctor, this child is too active, he never stays still for a moment, and his teacher always calls me to take him to the hospital to see if he has ADHD. Some children are really active? Does it look like ADHD? But it is the nature of children to be active. Some children’s hyperactivity is due to playfulness or lack of interest in learning, especially boys, but hyperactivity is not the same as ADHD. The difference between children’s hyperactivity and ADHD is the following: 1, self-control: ADHD children do not have a certain amount of self-control, their hyperactivity and impulsiveness is not occasion, their behavior is more impulsive, in the process of acting constantly changing patterns, a moment to turn a pencil, a moment to make a face, do things without rules, often without end. However, children who are active have strong self-control in an environment that requires quiet. When parents want their attention? Have some self-control? Can be quiet and no longer indiscriminately noisy. 2, with or without purpose: ADHD children’s hyperactivity is purposeless, chaotic, with a beginning and an end? Often make people feel annoyed, headache. They often have weak willpower, do things without end, often one thing is not done and go to another thing. While active children have strong willpower, their activities often have a certain purpose, and have plans and arrangements. 3, there is no real hobbies: ADHD children almost no real hobbies, no matter when and where, can not concentrate for a long time. Active children can pay full attention to the things they are interested in, and they also hate the interference and influence of others. 4. Understandable: ADHD children’s hyperactivity and impulsivity often have no cause and are often difficult to understand. Even if an active child is particularly naughty, he often has a reason for being active and can be understood. 5, the relationship with partners: ADHD children are often poor partnerships, often saying “they do not play with me. In contrast, active children generally have better partnerships. Therefore, in the face of naughty and active children, do not use adult standards to require children, but should grasp the characteristics of the psychological development of children at all ages to patiently guide, not bored to stop, otherwise it will prevent the normal development of intellectual and psychological children. However, if a child has difficulty sitting still in class, interrupts frequently, has difficulty following orders, is often distracted when others talk to him, and often acts riskily without regard to the consequences, he should be alerted to the possibility of ADHD, and should be taken to the hospital for consultation.
