So, what is Attention Deficit Hyperactivity Disorder? ADHD is subdivided into three types based on clinical presentation: inattentive, hyperactive-impulsive, and mixed. That is to say, some children may not be active, but just can’t concentrate well when doing things; some children may be active and impulsive, but also have poor concentration. These manifestations basically appear in the pre-school years, but often most prominent around the age of nine. As the age increases, the possibility of learning difficulties, oppositional defiance, poor behavior, emotional disorders, etc. increases significantly. Therefore, once your child shows the above signs, you should consult a doctor as soon as possible so as not to cause irreparable damage to your child’s growth and success. Some parents say that their children read comic books, animation books to see is a morning, full attention, motionless, is the class attention is not focused, how can I say that my child’s attention deficit? In fact, watching comic books, cartoons and listening to lectures and doing homework are not the same attention. The attention required to read comic books and cartoons is not casual attention, that is, attention that does not require the child to make an effort to pay attention. Because comic books and cartoons are full of new, varied, and interesting content, the child’s attention is naturally drawn to the plot of the story. In contrast, listening to the teacher and doing homework is boring and monotonous, and requires a great deal of willful effort on the part of the child to focus his or her attention on it. Therefore, if your child has problems paying attention to things that require a lot of willpower, you should be on the lookout for ADHD.
