In daily life, we often see some children appearing to squeeze their eyes, frown, clear their throat and involuntary rapid movement of their hands and feet, parents often take their children to the ophthalmology, quintessential medicine, neurology, repeated examination and treatment have no effect, and no problem can be found. Some parents also think that their children are deliberately misbehaving and give severe criticism, which results in more and more talk. In fact, it is the child who has tic disorder. Childhood tic disorder is an involuntary sudden, rapid, repetitive, non-rhythmic single or multi-site muscle movement or vocalization. It includes motor tics and vocal tics, which can occur sequentially or simultaneously. Motor twitches: Often eye twitches are the first symptom. Blinking is considered to be the most common first symptom of tic disorder. The twitching episodes are conscious and can be self-controlled briefly and disappear after falling asleep. It can be exacerbated or recurred with flu, diarrhea, fatigue, stress, or prolonged television viewing. Twitching episodes alternate between exacerbation and remission. The twitching can develop in the order of head and face, neck, shoulders, upper extremities, trunk and lower extremities, and the site can be a single site or multiple sites. Facial muscle twitching is mostly manifested as blinking, squinting, raising eyebrows, frowning, grinning, shrugging nose, making strange movements, etc.; head and neck muscle twitching is manifested as nodding, shaking head, jerking neck, shrugging shoulders, etc.; trunk muscle twitching is manifested as jerking chest, twisting waist, abdominal muscle twitching; upper limb twitching is manifested as rubbing fingers, clenching fist, shaking hands, raising arms, twisting arms; lower limb twitching is manifested as shaking legs, kicking legs, tiptoeing and even abnormal gait. Vocal tics: Vocal tics manifest as rapid, meaningless monotonous repetitions, such as constant throat clearing, coughing, grunting, growling, uttering, screaming, etc. Pediatric tics may be the result of the interaction of genetic and non-genetic factors (biological, psychological and environmental factors) during development. 1, psychological factors: common psychological factors: frightened, emotional excitement, sadness, children with excessive study load, chronic anxiety, watching thrilling TV, novels and exciting cartoons, experiencing unpleasant events in life, etc. Family factors: parental tension, divorce, reprimanding or scolding the child, parental discipline of the child is too strict, bad family environment, etc. 2, physical diseases: Infection factors: respiratory tract infections, tonsillitis, rhinitis, pharyngitis, conjunctivitis of the eyes, trachoma and other local irritation and produced. After various infections such as chickenpox, various types of encephalitis, hepatitis, etc., especially streptococcal infection may lead to the sudden onset of severe twitching, so the disease also has autoimmune neuropsychiatric disorder in children associated with streptococcal infection. Pharmacogenic factors: Children who take antipsychotics or central stimulants for a long time. 3, behavior imitation: some children are interested in other people’s blinking, twitching nose, clearing throat and other behaviors, repeatedly imitate and gradually behavior fixed. 4. Genetic factors: If there are people with tic disorder in the family, the chance of having the disease is significantly higher than if there are no people with the disease, so it is thought to be related to family inheritance. The most important thing to remember is that when a child has Tourette’s syndrome, he or she will attract the attention of others because of his or her unsightly appearance, and will be talked about or ridiculed. This causes psychological stress for the child and worry for the parents. In fact, mild tics can disappear naturally and do not leave after-effects, so there is no need to worry too much. For severe tics or chronic tics, it can affect the child’s daily life, learning, and social interaction. This can lead to anxiety, depression, low self-esteem and other psychological problems. Some children may become truant and have conduct problems, and even develop personality disorders and anti-social psychology. Therefore, timely treatment is necessary. The first thing you need to do is to take a comprehensive approach to the treatment of Tourette’s syndrome. First of all, it is necessary to treat physical diseases, such as trachoma, conjunctivitis, rhinitis, tonsillitis and other primary diseases in children. Secondly, parents should know that the child’s symptoms are not intentionally done by the child, never blame or punish the child for this, and do not always for some nagging, the more said the child more nervous, the heavier the symptoms. This disease will not make the child stupid, nor will it make the child psychotic. Parents should help their children eliminate psychological distress, reduce anxiety and depression, and adapt to the real environment. To create a relaxed and pleasant environment for the child, arrange the child’s daily life reasonably, encourage and guide the child to participate in a variety of interesting games and activities to divert their attention, avoid excessive excitement and tension fatigue, rhythmic sports activities can be carried out to exercise, appropriate to reduce the pressure and burden of learning, it is recommended that as far as possible not to play video games and watch horror movies or television, do not force the child to do something that is extremely repulsive to him. Do not force your child to do things that he finds extremely objectionable, such as forced piano practice, excessive extracurricular work, etc. Of course, children with severe symptoms need medical help.
