Yesterday, a parent came to see me at the Child Health Clinic and asked worriedly, “Doctor, what are the dangers of ADHD?”, “Can it be cured when it grows up?” and “Can it be cured when it grows up?” ADHD does cause some harm to children, such as: 1. Difficulty in maintaining attention: that is to say, attention cannot be highly concentrated and kept for a short period of time. For children who go to school, learning is a long-lasting and hard labor for them, without interest is not possible, pay attention in class, finish homework on time is a must, which requires a high degree of concentration, can no longer play like in the past. However, children with ADHD have poor initiative and self-motivation in learning, make small movements in class, and have to let their parents supervise their homework. At the same time, their attention is difficult to sustain, generally for students aged 10-12 years old to maintain 40 minutes of continuous learning is not difficult, and ADHD children are difficult to do this. 2, attention to the transfer of poor: ADHD children’s attention to a narrower range, the number of mastery of the number of significantly less than the average child, and attention to the stability of the poor, it is difficult to maintain attention, they can not grasp and understand the full content of the text! , and their academic performance fluctuates greatly. This reflects their insufficient breadth of attention and unstable attention, and is not due to low intelligence. Similarly, their coordination is poor, they are not good at distributing their attention, and they are highly susceptible to distraction. Completion of a task requires the eyes, ears, brain, hands, respectively, to control and cooperate with each other, such as the classroom eyes to look at the book, the blackboard, ears to listen to the lecture, but also to think, hands to take notes, this time they will appear to be busy, overwhelmed. 3, attention to the selective poor: attention to the unintentional attention and intentional attention. ADHD children’s unintentional attention is dominant, changes in the surrounding environment, the emergence of new stimuli can easily cause reactions, the intentional attention to things but can not see. When they are doing homework at home, they will always listen to adult conversations and noises outside the window; on the way to school, they will also be attracted by toys in the store and forget to go to school. Their attention is unconscious and purposeless; they see and do whatever they see, and they don’t know to recognize whether they should do it or not. As for the question of whether ADHD children can heal themselves in adulthood, experts explain: with the deepening of research on ADHD, we can tell parents with certainty that if not actively treated, most children will not heal themselves as they grow older, and even as they grow older, some co-morbidities slowly appear, such as learning difficulties, emotional disorders and social disorders, which have a bad impact on the child’s schooling, career and social life. This will have a negative impact on the child’s academic, professional and social life. Parents should not take the chance that their children will “get over it” as they get older.
