It is the nature of children to be active, and it is not strange for them to be mischievous. However, involuntary, purposeless, repetitive, rapid eyebrow squeezing, mouth, nose, tongue, or even twisting the neck, stomach, shrugging, arm flinging, jumping, or accompanied by voice, cursing, this is not children’s naughty or “bad”, but in recent years gradually increased a child mental illness tic disorder. Tic disorder is a neuropsychiatric disorder that begins in childhood and adolescence and has a clear genetic predisposition, mainly manifesting involuntary, repetitive, rapid one or more parts of muscle movement twitching and vocal twitching, and may be accompanied by inattention, hyperactivity, compulsive actions and thinking or other behavioral symptoms. Of course, in most cases, only one or two of these symptoms are present in a child, and the symptoms may be mild or severe. In the early stages of the disease, some symptoms can be temporarily controlled. For parents, teachers, and even some doctors who lack knowledge about children’s mental health, it may be difficult to treat such symptoms as “bad problems” or “trachoma”, “conjunctivitis”, or “pharyngitis”. If the child is treated as “bad” or “trachoma”, “conjunctivitis” or “pharyngitis”, it will not only delay the treatment of the child, but also bring some harm to the child’s mind and body. Therefore, it is necessary to popularize the knowledge of tic disorders in children and to prevent and treat them at an early stage to promote their mental and physical health. There are various clinical manifestations of this disease, summarized in three main categories: 1, temporary tic disorder. Also known as habitual spasms, transient tic disorder. It is the most common type of twitching. It is characterized by simple or transient muscle twitching, and is generally most common in the eye muscles, facial muscles and neck muscles. The most common symptoms of this disorder are repeated blinking, nuzzling, head shaking, neck tilting, squinting, shoulder shrugging, forehead wrinkling, nose sucking, mouth opening or limb fluttering and trunk twisting. A few of them simply show stereotyped, repetitive uttering of breath, nose twitching or throat clearing. These twitches can be restrained by will for several minutes to several hours. The duration of the disease lasts at least two weeks, but not more than one year. 2. Chronic tic disorder. The symptoms are simple or complex motor twitching (twitching of certain muscle groups) or vocal twitching, but motor and vocal twitching do not exist simultaneously. Motor tics are usually the most common, and the symptoms tend to be persistent and stereotyped. The duration of the disease lasts at least one year, and some patients may have symptoms that last a lifetime. 3, vocal and multiple motor combined tic disorder. Also known as tic-obscene syndrome, Tourette’s syndrome, multiple tics, multiple tics, impulsive tics, etc. The disorder was described in detail by the French physician Tugret in 1928 and has been extensively studied by the medical community since then. The syndrome is characterized by twitching of the articulatory muscles, meaningful or nonsensical sounds, and frequent swearing, which is very painful for the patient. The syndrome is also often accompanied by imitative movements, imitative speech, repetitive speech, obsessive-compulsive movements, or obscene behavior. Patients are sometimes emotionally unstable, hyperactive and have more bad behavioral habits, which often lead to their own psychological distress and even affect their daily life and study. Treatment: 1. Psychological behavior treatment. Tic disorders of different severity can bring different degrees of disturbance and impact on the daily life and learning of the affected children themselves and their families. Although we cannot determine the role of psychological factors in the pathogenesis of tic disorder, the symptoms of the affected children are often aggravated by factors such as trauma, mood swings, peer relationships or study burdens. Therefore, in addition to pharmacological treatment, psycho-behavioral treatment is essential. Help parents and teachers understand the nature and characteristics of the child’s disease and explain that the disease is not a result of the child’s mischievousness or intentional behavior, so as to obtain their cooperation and support for proper education and patient help. Reasonably arrange the rest time and activities of the child to avoid stress and strain. 2. Drug treatment. So far, we have not found a complete cure for tic disorder, and the medication used is still a treatment to control the symptoms. There are two main types of medications used to control the symptoms of tics, one is non-psychoactive drugs used for the treatment of mild tics, including colistin, guanfacine, baclofen and anti-epileptic drugs. The other category is antipsychotic drugs, including haloperidol, Tebrile, thiopirid, risperidone, quetiapine, aripiprazole, and amisulpride. The overall goal of treating symptoms is not to completely control them, but to reduce them and not to produce further impairment of psychosocial functioning. 3. Neurosurgical treatment. Rarely chosen.
