”My child is suffering from ADHD, how is it possible?” When 10-year-old Tingting was diagnosed with “ADHD”, her mother’s reaction was strong. Indeed, Tingting is very different from the perception of an ADHD child who is “always moving around”, she is always quiet and hiding in her own world. She always looks out of the window in class, daydreams all day, or plays with her school bag, pencils and erasers alone. Whenever the teacher asks a question in class, she doesn’t even know what question to ask, and she is often distracted when participating in group activities. She procrastinates on her homework, drinks water later, goes to the toilet later, and can’t finish the homework that her classmates can finish in one hour, but she can’t finish it in three to four hours. In addition, it is not uncommon for her to lose her books, pencils, stationery boxes and other school supplies at home or forget them at school. As a result of these “little root” like behaviors and the resulting poor academic performance, Tingting was scolded by her mother and criticized by her teachers. Over time, Tingting felt inferior to others in every way and even considered herself a “dumb kid” (when in fact her intelligence was perfectly normal). She became less and less talkative and depressed. Many people may wonder: How can it be ADHD if you don’t like to move? ADHD, known as Attention Deficit Hyperactivity Disorder (ADHD), has three core symptoms: attention deficit (commonly known as distractibility and inattentiveness), hyperactivity and impulsivity. Some children are predominantly attention deficit, some are predominantly hyperactive and impulsive, and more often all three co-exist. Some surveys show that about 10-15% of children with ADHD do not show obvious hyperactivity, but inattention as the most prominent manifestation. These children’s attention is difficult to focus, or the attention span is short and does not match the actual age, such as in class, often looking around, distracted, or seemingly quiet, but actually “distracted”, “slip”, listening but not listening. When doing homework, they play while doing it, scribble, scribble, and make many mistakes. They cannot concentrate on one thing, and often do things without finishing them. In girls with ADHD, the degree of hyperactivity is generally lighter than in boys, and is mostly manifested by inattentiveness. This is the case with Tingting. This “inactive” child with ADHD is very easy to be ignored by parents and teachers, so it should attract our attention and attention. For children with attention deficit hyperactivity disorder like Tingting, in addition to receiving treatment from a specialist, psychological and behavioral treatment at home is also particularly important. Parents should first understand that their children are not mischievous, nor are they deliberately delaying the completion of homework, but rather they have a weak active attention span and lack self-control. Therefore, the child should not be taught by scolding or corporal punishment. Parents should create a quiet learning environment for their children, keep in touch with their teachers, understand their children’s performance in school, patiently point out their children’s shortcomings and urge them to correct them, and praise them for their merits.
