Adolescents face the conflicts that psychological development and physiological development cannot develop in a coordinated manner. At the same time, they have to face a series of brand-new life issues, such as the awakening of sexual consciousness, academic pressure, peer pressure, the initial formation of self-concept, and the sharply increased external pressure. They are prone to psychological problems such as self-centeredness, biased thinking, confused self-concept, emotional volatility, and improper behaviors. They show mild emotional disorders (e.g., sensitivity, suspicion, anxiety, tension, etc.), or neurotic symptoms such as depression and anxiety, and in severe cases, psychotic symptoms like capriciousness, talking to themselves, hallucinations, and delusions may occur. Yinzi, a senior psychotherapist, innovatively applies traditional medicine to the psychological and psychiatric treatment of adolescents. In this book, she begins with depression, generalized anxiety, pre-exam anxiety, social anxiety, eating disorders, schizophrenia, bipolar disorder, Internet addiction, and other disorders that often occur during adolescence, and thoroughly analyzes them at the physiological, psychological, and social levels through detailed case studies. Explaining the theory and processes of treatment to readers, this book allows doctors and parents to discuss how to take care of adolescents' mental health and help them grow up healthily from a broader perspective.
