Tic disorder is medically known as tic disorder and is generally classified as temporary tic disorder, chronic tic disorder, and multiple tic disorder, which refers to involuntary, purposeless, repetitive, and rapid muscle contractions. The symptoms are blinking, eyebrow squeezing, forehead wrinkling, nose sniffing, lip smacking, neck stretching, head shaking, lip biting and imitating strange equations. Some children have twitching that is always confined to one part of the body, others have twitching that is not fixed, and others have twitching that occurs in all parts of the body at the same time. Most children in this category are sensitive, timid, misfits, easily excited and agitated, and some children also have symptoms such as enuresis, night terrors, stuttering and hyperactivity. There are many causes of twitching, some of which start with protective or habitual movements due to discomfort in certain areas, such as blinking, which can be caused by conjunctivitis or foreign objects in the eyes; after the above causes are removed, inert foci of excitement are formed in the cerebral cortex, so twitching movements can occur repeatedly. The common factors are: genetics, stress, anxiety, shock, autoimmune problems after infection such as upper respiratory tract infection, etc.; the following aspects should be noted: 1, do not blame the child, because the more blame the more nervous, involuntary movements will be more frequent, the child will gradually become timid and inferior. 2, ignore, do not prompt. 3, parents should encourage and guide the child to participate in a variety of interesting games and activities to divert their attention and relax. 4, parents do not have to worry about this tic, not to mention the child will grow up to fall into the problem the vast majority of children heal is good. The current belief is that children with tic disorder can be relieved by themselves if the symptoms are mild. If the symptoms are serious, you can use medication under the guidance of a physician. Nowadays, many children love to eat fast food and drink cola, watch TV and play computer for a long time, which will have a great adverse effect on children can trigger tics. The psychological pressure of learning, with the development of society, the increasing pace of life, the family to the development of only child, the parents of the pressure of learning, competition and the complex and changing social environment to children and adolescents brought different degrees of tension stimulation and psychological pressure. Almost all children like to have a partner to play with; however, many children lack a partner and often play alone; this “partner crisis” will have a negative impact on the healthy growth of children. The lack of playmates makes children more dependent on television and computers, and medical research has shown that prolonged viewing of television and computers can greatly increase the likelihood of tic disorders in children.
