When it comes to depression, it often gives the impression of pessimism, negativity, and a worried face. However, in the clinical diagnosis process, many teenagers have different symptoms of depression. What are the signs of depression in children? At the age of 15, Xiao Li has been experiencing inexplicable headaches for a while, eating excessively every day, and gaining weight from 92 pounds to 117 pounds in just three months. The most obvious change is that he is prone to getting angry with his parents and shouting every day that he doesn't want to go to school. My parents thought that Xiao Li was in adolescence and it was normal for him to be rebellious. It wasn't until his academic performance dropped from the top 5 in the class to over 20 that he realized something was wrong. After detailed mental examination and psychological evaluation, Xiao Li was diagnosed with depression. Being angry, confrontational, irritable, and irritable with parents can easily lead parents to mistake it for adolescent rebellion or excessive academic pressure, but these are also manifestations of adolescent depression. From clinical experience, parents can preliminarily determine whether their child is at risk of depression based on the following symptoms. 1. The previously outgoing and outgoing personality suddenly changes, unwilling to socialize with friends, and even unwilling to go to school or become addicted to the internet; 2. Becoming irritable and irritable, preventing people from approaching oneself, frequently talking back to parents, losing temper, and liking to throw things; 3. Overindulgence in drinking and overeating, uncontrollable consumption of large amounts of food (such as junk food and carbohydrates), and rapid weight gain (some children may also experience rapid loss of appetite); 4. Sleep problems occur, manifested as insomnia, difficulty waking up in the middle of the night, frequent early awakening, and nightmares. Some children also exhibit drowsiness, feeling unable to wake up and feeling lethargic during the day; 5. I feel that my body continues to experience various discomfort, such as headaches, stomach pain, nausea, palpitations, chest tightness, etc., but I cannot find the cause after going to the hospital for examination; 6. Becoming "lazy" and not interested in many things, even unwilling to leave the door; 7. Feeling useless, always blaming oneself, and believing that one should be punished even if it is not their fault; 8. Things become procrastinating, completing homework and classroom assignments takes more time than before, resulting in reduced facial expressions, slow reactions, and significantly reduced body movements. Good parent-child relationship is the cornerstone of health. A meta-analysis of over 160 studies in China showed that 15 psychological and social risk factors are associated with the onset of depression in adolescents, including poor parent-child communication, negative life events, academic pressure, abuse, poor family function, bullying, and poor family cohesion. The first thing parents need to do to help their children stay away from the quagmire of depression is to establish rules and boundaries for their children. Famous child psychologist Piaget believes that children aged 2-8 are in the pre operational stage of cognitive development, and parents must seize this critical period of setting rules for their children to understand them. At the same time, parents should not excessively intervene and control their children in the name of love. In this process, children are able to make independent choices, solve problems independently, and maintain their sense of boundaries. Parents should respect the boundaries of their children's areas, not enter their children's rooms without permission, and not open their children's storage cabinets without permission. Secondly, parents should teach their children to manage emotions and accept their imperfections. Children should be guided to use language clearly
