1.Psycho-behavioral treatment Tic disorder (TD) of different severity can bring different degrees of disturbance and impact on the daily life and study of the affected children themselves and their families. The symptoms of children are often aggravated by mood swings, trauma or overload of study, etc. If delayed to adults, many psycho-behavioral problems such as schizophrenia, depression, psychasthenia and anxiety disorders can easily appear. Modern medical research shows that children with this disease have personality characteristics such as introversion, neuroticism and psychoticism. Therefore, psycho-behavioral treatment is essential for any child with TD. Treatment for this disease is mainly supportive guidance and education of the child’s family, school and other relevant personnel at the beginning, and medication can never replace these efforts. Among them, for children with mild TD who have good social adjustment ability, only psychological behavior treatment is needed, and there is no need to apply medication, but mainly to give psychological adjustment and psychological guidance. Telling patients and their families and partners, school teachers about the nature of the disease, rebuilding the school environment and providing supportive guidance are two methods that are sufficient to avoid the use of medication. The purpose of treatment is not to eliminate the tic symptoms directly, but mainly to support and help the patient to eliminate psychological distress, reduce anxiety and depression, and adapt to the real environment. Psycho-psychological treatment often requires the full cooperation of the doctor, family and school to achieve better results, the main of which is psychological support and guidance for the child and his parents. One of the most important aspects of treatment is to teach the patient and family members about tic symptoms and related behavioral disorders, to help the child eliminate nervousness and low self-esteem, and to understand the disease correctly, especially to let parents know that the symptoms are pathological manifestations of the disease itself, not the child’s mischievousness or intentional behavior, and not to blame or punish them for it. At the same time, we should also relieve the parents of some unnecessary worries, eliminate their excessive tension and worry because they do not understand this kind of disease, and obtain their cooperation and support, which is conducive to parents’ correct education and patient help for their children. We should create a relaxing environment for the child, arrange the child’s daily life reasonably, encourage and guide the child to participate in various interesting games and activities to divert his or her attention, avoid excessive excitement and fatigue, reduce the pressure and burden of study, do not play video games and watch horrible movies or TV, do not force the child to do things that are extremely repulsive to the child, show concern and understanding to the child, and enhance the child’s self-confidence. The child’s self-confidence will be enhanced, which will be conducive to the recovery of the disease. Behavior therapy TD’s behavior therapy methods include positive reinforcement, negative practice, assembly practice, self-monitoring, relaxation training and behavior reversal training. A combination of the above methods can be used for the same patient. A randomized controlled study design program can help determine the efficacy of TD behavioral therapy, especially for the assessment of the efficacy of the combined treatment of behavioral therapy and pharmacotherapy. 4, diet adjustment and environmental therapy In addition to drug and psychotherapy, attention should be paid to the proper arrangement of daily work and rest time to avoid excessive stress and fatigue, and to participate in certain sports and recreational activities to make them in a relaxed and pleasant environment as much as possible. Food additives can contribute to the development of behavioral problems in these children, including hyperactivity and learning difficulties. Caffeinated beverages can exacerbate tic symptoms. For this reason, food additives, coloring, caffeine, and salicylic acid should be avoided in the food of these children.
