In life, you may find some children with “special performance”, such as frequent blinking, eyebrow squeezing, squinting, pouting, nose, head shaking, shoulder shrugging, neck shrinking, arm stretching, arm flinging, chest lifting, waist bending, belly bulging, body rotation, leg stirring, throat clearing, coughing, throat whirring, and even appearing involuntary yelling, cursing, repetitive language, etc. If you have a tic disorder, you have to be highly alert to it! Tic disorder in children, as a very difficult social disease in the last decade, has been troubling parents, children and pediatricians; the disease is often very volatile, sometimes light, sometimes heavy, and sometimes may also remit on its own for a period of time, the site, frequency and intensity of twitching can change constantly. With the changing times and the rapid development of people’s material and spiritual world as well as the diversity of values, the number of children with tics can be said to be increasing, seriously affecting their physical and mental health and growth and development. Tic disorder, which is a chronic neuropsychiatric disorder in children, its ultimate change lies in the dysfunction of the nervous system; however, it is very closely related to many aspects of the child’s mental, psychological and immune system. First of all, the family, educational and social environment has an important role in the triggering or exacerbation of tic disorders. For example, parents are too strict with their children, too much criticism, and children are overburdened with studies; this happens more often in life with children from families such as teachers and lawyers, where parents unconsciously bring home professional habits and impose them on their children. Also include unpleasant family life environment (parental divorce, quarrels, over-indulgence, etc.), the child’s long-term anxiety and tension or sensitive and introverted personality psychology. Secondly, long hours of watching TV, cell phones or being obsessed with computer games, bad eating habits (love of sweet, fried and puffed food, various drinks, fast food, etc.) and wrong daily routine (staying up late, little or excessive outdoor exercise) also seriously interfere with the performance of tics and the degree of recurrence; and these life behaviors are not correlated with the parents’ high or low cultural quality. It was also found that recurrent colds, allergies or other infections in children can also cause tics to recur or worsen symptoms; low immune function is an endowment for children with tics.
