Tic disorders (TD) are a group neuropsychiatric disorders with childhood onset characterized by tics, i.e. repetitive, sudden, and involuntary movements or vocalizations; and Tourette syndrome (TS) is the most severe form of TD. Their clinical manifestations are diverse; and are often associated with various psychopathological and/or behavioral comorbidities, including attention deficit hyperactivity disorder (ADHD), obsessive-compulsive disorder (OCD), anxiety, depression, and sleep disorders. Individual severity and response to treatment are highly variable, and there are some refractory cases, which are less responsive to conventional TD treatment. TD/TS are also common in the Chinese pediatric population. To help improve the understanding of TD for pediatricians and other health professionals, and to improve its diagnosis and treatment in China, the Chinese Child Neurology Society (CCNS) has developed an Expert Consensus on Diagnosis and Treatment of TD in China, which is based on our clinical experience and the availability therapeutic avenues. It is focused on clinical diagnosis and evaluation of TD and its comorbidities, psychological and educational intervention, nonpharmacological therapy, pharmacological treatment, including traditional Chinese medicine and acupuncture, as well as prognosis in children with TD in China. A summary of the current status of TD and up-to-date diagnosis and treatment recommendations for TD in China is presented here.

China has a population of 1.3 billion, of which 238 million are children under age 15. The rapid economic development and social reforms that have taken place in recent years all had a great influence on child and adolescent mental health. Though a nationwide prevalence study for child and adolescent mental disorders in China is lacking, several regional studies have shown the prevalence of mental disorders in children to be close to the worldwide prevalence of 20%. This article reviews the current status of Chinese child psychiatry, the prevalence of specific disorders in China and the influence of culture on the diagnosis and treatment of child and adolescent mental disorders. Several important social issues are also explored in detail, including the one child policy and left-behind children of migrating workers. Changes in family structures along with the growing competitions in life have weakened the traditional social support system. As a result childhood behavioral problems, mood disorders in young college students, substance abuse and youth suicide are all increasing in China. Many who suffer from mental disorders are not adequately cared for because the scarcity of qualified service providers and pathways to care. This article also lists some challenges and possible solutions, including the multidisciplinary and culture sensitive service model for child mental health. Relevant laws, policies and regulations are also introduced.

Children who are left behind when their parents migrate for work have a high prevalence of emotional and behavioral problems, which affect social function and increase family burden. To date, no national survey has been conducted on the emotional and behavioral problems of left-behind children (LBC) in China. This study aimed to investigate the emotional and behavioral outcomes of primary school LBC in the fourth grade in impoverished rural China and the possible influences of family environment and parenting practices. A cross-sectional study was carried out in 27 rural counties in the central and western parts of China from November 2016 to January 2017. The method of quota sampling was adopted to achieve a representative sample using postweighting adjustment. The survey sample was distributed proportionately across each county. LBC were defined as children aged 17) was significantly higher in the LBC group than in the NLBC group (15.6% vs. 11.6%; p < .01). Binary regression analysis showed that high levels of insomnia (odds ratio [OR] 1.54, 95% confidence interval [CI] 1.04-2.27), loneliness (OR 1.65, 95% CI 1.13-2.43), and self-harm (OR 1.92, 95% CI 1.17-3.16) may increase the risk of abnormal SDQ total scores in LBC. LBC showed a higher prevalence of abnormal SDQ total scores than NLBC. Insomnia, loneliness, and self-harm behavior were associated with abnormal SDQ total scores in LBC.
