Most children with attention deficit disorder do not heal on their own. However, after treatment, the brain structure tends to be normal and the level of brain development is better than in untreated children, so the disease is preventable and treatable. In addition, early diagnosis and treatment can improve the overall life and quality of life of children. If the child is not treated in time, long-term follow-up problems such as anxiety and depression can occur. Therefore, early diagnosis and standardized treatment are needed to improve the quality of life of children throughout their life cycle.
