Tic disorder is a sudden onset of involuntary movements that may be accompanied by single or multiple muscle group twitches that are more limited. Eye, face, and neck muscle twitches are usually the most common, and symptoms fluctuate or shift in location over weeks or months, progressing to the neck or upper and lower extremities. The common simple motor twitches are blinking, eyebrow squeezing, forehead wrinkling, eye rolling, nose tucking, lip biting, mouth pouting, mouth opening, tongue stretching, head nodding, head shaking, neck tilting, neck stretching, shoulder shrugging and other movements. It can also be seen in the upper and lower extremities, such as throwing hands and kicking legs. However, a few patients may exhibit complex motor tics, such as eye expression and rotation, facial movements and expressions, and head posture and movements. Simple vocal tics are characterized by simple, rapid recurrent coughing, eructation, or throat clearing. The frequency and severity of twitching symptoms vary, and usually have no significant impact on the child’s daily learning and adaptation to the environment. The neurological examination is usually free of abnormal signs. There are no localized focal lesions in the vocal organs. The duration of the disease usually does not exceed 1 year. The exact factors that cause tic disorder are not clear, but in general are related to the following factors: 1, genetic factors: tic disorder can have family clustering, and tic disorder is more common in the family of the affected child than in the general population. 2. Somatic factors: Children often start with habitual movements due to discomfort in a certain part of the body and become fixed, such as blinking due to conjunctivitis or impingement irritation, nose aspiration due to upper respiratory tract infection or rhinitis, and facial twitching. When the local cause is removed or disappears, the twitching symptoms still persist. 3, organic factors: some children often have birth injuries, asphyxia, premature birth, etc. 4, psychosocial factors: such as unpleasant events in the family, excessive mental stress, excessive stressful frightening situations in learning can also cause twitching. 5, drugs: due to inappropriate long-term or high dose application of central nervous stimulants or anti-psychotic drugs, etc. can produce tics. The danger of tics is obvious, because the symptoms of tics are often ridiculed and taunted by classmates, so that the affected children have low self-esteem, personality isolation, over time the child becomes lonely, reluctant to contact people, and even revenge and hostility towards the mockers. Therefore, it is easy to cause psychological problems in children. The actual fact is that you can find a lot of people who are not able to get a good deal on the subject. For those who have mild symptoms of tic disorder and little interference damage, no special treatment is needed. Those with more pronounced symptoms can be treated with medication, such as small doses of oral haloperidol or thiopride. ②Acupuncture therapy, suggestion or relaxation therapy are used to facilitate recovery. ③Psychotherapy, giving correct education and guidance, eliminating various psychological tension factors of the affected children, establishing confidence in overcoming the disease, and making reasonable arrangements for rest and living and study life. Participate in physical exercise appropriately to avoid overexertion. Parents should be instructed to change the way of education, overcome impatience, and prevent the phenomenon of seeking full and harsh blame on the affected child. ④Treatment of physical diseases, for children with trachoma, conjunctivitis, rhinitis, respiratory tract infections, should promptly go to the appropriate hospital specialist for treatment.
