Depression in a 13-year-old child should be promptly and clearly diagnosed in a specialized psychiatric or psychological department. Determine the type of depression and the severity of the symptoms, and select medications for targeted treatment. At the same time, parents need to actively observe their children’s performance in daily life to determine the causes of depression or aggravation of symptoms, such as excessive academic pressure, high mental tension, or the family atmosphere they live in is too tense, which can lead to the appearance or aggravation of depressive symptoms. In such cases, parents should provide a warm and comfortable environment and communicate with their children in a timely manner to understand their inner activities. At the same time, parents should try to reduce stress, not to create too much pressure, and not to scold the child roughly when the expected goal is not achieved. It is also important to identify problems with the child, while providing more encouragement to maintain a certain level of self-confidence. Through close cooperation of parents and standardized treatment by professional psychiatrists or psychologists, most children’s depression can gradually improve.
