Although the behavioral characteristics of hyperactivity are very similar to naughty, the causes are different.
It is difficult for a teacher to assess a student as having hyperactivity disorder based solely on observational information. A comprehensive assessment by a specialist is required before the determination can be made. Many times, teachers may find that the student with hyperactivity problems is not the naughtiest one in the class.
Hong Kong hyperactivity disorder schoolchildren
According to statistics, among 100 children in Hong Kong, about 4 to 5 have hyperactivity disorder/attention deficit disorder. Most of them are boys.
Causes of hyperactivity disorder
As for the causes of hyperactivity disorder, it was misunderstood in the early days that it was caused by poor parental discipline, family problems or certain foods. Some parents also feel guilty about this. Now, decades of medical and scientific research have accumulated, and there is evidence that hyperactivity disorder is based on physiological factors, related to genetics and brain function, and is not caused by parenting methods, parental relationships or family environment. However, if the parents of children with hyperactivity disorder do not know how to discipline their children, coupled with other family pressures, the problem of hyperactivity disorder will become more serious. Therefore, in programs to help children with hyperactivity disorder, these family factors must also be addressed.
Medical research has confirmed that hyperactivity is genetically related, and a new generation of genetic tests can help doctors and parents understand their children's condition better.
Symptoms of hyperactivity disorder, do these behavioral characteristics disappear with age?
Some parents have begun to notice some behavioral characteristics of hyperactivity disorder in their children in early childhood (about three years old), and they become more obvious after entering elementary school. The age at which hyperactivity problems begin is generally around six or seven years old. As we age, some hyperactive behavioral traits become more controlled and less obvious, but research shows that they do not disappear with age.
