Childhood ADHD is a common psychological and behavioral problem in childhood. Psychologists call it “attention deficit and hyperactivity disorder,” and in society, especially elementary school teachers and parents tend to call hyperactive or inattentive children “ADHD,” when in fact many of them are normal children. So what exactly is considered “hyperactive”? Is “hyperactivity” a disease? In fact, it is the nature of children to be active, many people say that active children are smart, from the perspective of developmental psychology, there is indeed truth. This is because children who are active are more creative. The ability to use their hands is stronger than that of the less active children. So how do you distinguish between normal and abnormal hyperactivity? To be precise, “hyperactivity” in ADHD is inappropriate. It is not only an increase in the amount of movement, but also a change in the nature of the movement. Usually, in a psychologically normal child, the activity should be appropriate to the environment in which it is taking place and should be goal-oriented. For example, at home, a child may do certain things to get the attention or reprimand of parents in order to get their attention. These activities, in fact, are an outpouring of mental activity for the child, but are not what they are expected to be for the parents, so it is treated as a manifestation of ADHD. Hyperactivity must be distinguished from these activities that annoy parents but are actually normal, and parents become annoyed because they are unfamiliar with the child’s psychological characteristics while placing too high expectations on the child’s self-control. It must also be distinguished from the lack of appropriate and beneficial play opportunities for the child, and must be an objective assessment of the field in which the child finds himself or herself. In addition hyperactivity in normal children generally occurs between the ages of 3 and 6 years, and is more common in boys. Their hyperactivity can be self-controlled after appropriate education and training, and can be corrected quickly and effectively. In addition, in clinical work, we have seen certain physical and psychological disorders that can also appear similar to ADHD. For example, hearing and visual impairment. Allergic diseases. Anemia. Adverse drug reactions . Hyperthyroidism. Epilepsy, and tic disorders commonly seen in psychological disorders. Autism. Learning phobia. Childhood schizophrenia, etc. Therefore, if parents find that their children have hyperactivity problems, they should seek medical treatment as soon as possible.
