Does your child involuntarily make unusual movements such as blinking, tilting the mouth, shrugging the shoulders, making faces, etc.? Or does your child always make dry coughs, sniffing noises, or strange noises? Or even unexpectedly jumping, jumping, twisting the body, hitting themselves, repeating words, imitating words, speaking foul language? This is not a bad habit of your child, but a disease called childhood tic disorder. 1, the main features of tic disorder Tic disorder is a group of sudden involuntary muscle twitching in the head, limbs and trunk, and (or) with explosive guttural sounds and behavioral disorders of neuropsychiatric disorders, commonly known as tic disorder. In the past 20 years, the prevalence of the disease has been gradually increasing, with a prevalence rate of 0.05% to 3%, mostly at the age of 5 to 12 years old, with 90% of the first onset before the age of 10 years old, with more males than females, and a male to female ratio of 4 to 6:1. The involuntary twitching of the neck, shoulders and limbs, such as neck twisting, head shaking, shoulder shrugging and limb shaking, frequent throat clearing or dry coughing, or in severe cases, “uttering”, “roaring” or screaming. The disease is often combined with attention deficit-hyperactivity disorder, obsessive-compulsive disorder, social disorders, learning difficulties, emotional disorders, self-injury and aggression, which has a serious impact on the learning, life and social activities of the affected children, and even affects the employment and marriage of the patients. 2, modern medical understanding of the disease Most people believe that it is related to spiritual factors, psychological factors, environmental factors, genetic factors, abnormalities in neurotransmitter metabolism, minor organic damage to the central nervous system and sex hormone dysfunction. In recent years, some scholars have suggested an association with infection, while others have explored the genetic studies related to the disorder from a molecular biology perspective, suggesting a close relationship with the dopamine receptor gene. Although the etiology of tic disorder is related to genetic, infectious immune and psychosocial factors, none of them can fully explain the specific manifestations and severity of the disease, which may be the result of a combination of genetic and environmental and other non-genetic factors. The incidence of the disease is on the rise, with a lifetime prevalence of 12%-16%, often combined with attention deficit-hyperactivity disorder, obsessive-compulsive disorder, social disorder, learning difficulties, mood disorders, self-injury and aggression, which has a serious impact on the learning, life and social activities of the affected children, and even affects the employment and marriage of the patients, and brings a heavy psychological burden to parents. Modern medicine mostly uses dopamine receptor blockers such as haloperidol and Tebri, which have certain efficacy in controlling tic symptoms, but their side effects cannot be underestimated. If left unattended the results can be quite serious. The causes of tic disorders in children are both congenital and acquired. Insufficient congenital endowment includes genetic factors that cause genetic defects, birth injuries that result in head injury, premature birth, difficult birth, birth asphyxia, etc. Acquired factors include viral infections, allergies, head trauma, emotional depression, accidental stimulation, environmental pollution and environmental changes, etc. The combination of congenital and acquired factors results in the imbalance of yin and yang, with yin not controlling yang and yang being active. The disease is located in the liver and is closely related to the dysfunction of heart, lung, spleen and kidney, and internal disturbance of wind, fire and phlegm. The disease is classified into three types: one is qi depression and fire, depletion of yin essence, liver blood deficiency, loss of nourishment of the meridians, and internal movement of false wind; the second is spleen deficiency and phlegm accumulation, phlegm and qi interconnection, congestion in the chest, the mind is blinded, and the body is not free; the third is yin deficiency and wind movement, deficiency of kidney yin, water does not contain wood, and internal movement of false wind. 4.Therapeutic advantages of Chinese medicine At present, the treatment of tic disorder has no special medicine, and it is a clinically difficult disease. However, there is no evidence-based evidence that these drugs can improve the natural course of tic disorder. improve the natural course and prognosis of tic disorders. “The essence of ancestral medicine is to refine the symptoms and signs of the child, and to combine drugs under the principles of clearing the liver and fire, strengthening the spleen, resolving phlegm, nourishing yin and subduing yang, and pacifying the liver and wind. The study found that foods rich in tryptophan and salicylic acid and beverages containing caffeine are more likely to suffer from tic disorder; meanwhile, the idea of “prevention before illness” in Chinese medicine has profoundly influenced clinical practice, and modern research considers this disease as a neuropsychiatric disease. Therefore, for normal children, parents should take a guiding family education approach to encourage and support the healthy growth of children, and for children with tic disorder, they should actively take medication based on evidence-based treatment and supplemented by psychological and behavioral treatment, in order to promote the physical and mental health of children with comprehensive, comprehensive, scientific treatment. In addition, this disease is often accompanied by symptoms such as ADHD and OCD, so it is necessary to pay great attention to the accompanying symptoms in clinical practice and actively treat them. The clinical evidence shows that the efficacy of Chinese medicine in the treatment of childhood tic disorder is certain, with few side effects, and it is better to reduce the toxic side effects for children who have been taking western medicine for a long time. 5. Suggestions Tic disorders generally have a development process from mild to severe. When the condition is mild, the child’s psychological state is good, has not yet formed psychological pressure to cooperate with the treatment, the effect is fast. When the symptoms are complex, serious, recurrent, the surrounding people often can not understand, causing misunderstanding or even shame, the child’s psychological damage to varying degrees, this time the treatment is more complex. It is clinically found that the longer the history of the disease and the older the age of seeking treatment, the slower the treatment effect. Adolescence is a period of special growth and development, a period of knowledge seeking, competitive and independent personality formation, and the pressure of competition and challenges from many parties. Therefore, it is undoubtedly most meaningful for the child to have his or her condition controlled before puberty. Therefore, early detection and treatment of tic disorder is essential.
