In daily life, you can often see children who like to shake their heads, blink their eyes, and shrug their shoulders constantly. These movements are purposeless and often uncontrollable, more pronounced in crowded or stressful situations, and disappear after sleep. At first, parents are very anxious, thinking that their children have “trachoma”, “conjunctivitis” or “pharyngitis”. But to the hospital to check the eyes and throat is all normal, the family is easy to think that the child’s “bad habits” or “bad habits” and ignore delayed treatment. In fact, what these children have is a common disease, medically called tic disorder. It occurs mainly between the ages of 2 and 12, and is more common in boys. The tics can be either motor or vocal. Motor tics such as involuntary blinking, nodding, frowning, sucking mouth, shrugging shoulders, making faces, drumming belly, etc.; vocal tics such as dry cough, light cough, clear throat sound, nasal sound, severe cases can appear to swear, repeat other people’s words, etc.. There are three types of transient tic disorder, chronic tic disorder and multiple tic disorder. Transient tic disorder refers to motor tics without or with vocal tics and vice versa, and the duration of the disease does not exceed one year; chronic tic disorder refers to motor tics or vocal tics only, and the duration of the disease exceeds one year; multiple tic disorder refers to both motor tics and vocal tics, and the duration of the disease is more than one year. Tic disorders can be complicated by a wide range of behavioral problems, such as hyperactivity, depression, anxiety, obsessions, etc., which can have a negative impact on the child’s learning and life. It should be taken seriously by parents. Treatment is mainly psychotherapy, supplemented by medication. Psychological treatment includes helping to understand the disease correctly, warning parents not to pay too much attention to the child’s tic symptoms, not to take the child to too many doctors, arranging the child’s daily life reasonably and reducing the pressure of study, and communicating with school teachers and classmates. For children with severe symptoms that affect their daily life, study or social activities, if psychotherapy alone is not effective, medication should be added, such as Haloperidol, Tebretol or Colistin tablets. However, many children are reluctant to take these medications because of their adverse effects, such as dizziness, fatigue, and impaired liver function.
