The treatment of attention deficit hyperactivity disorder is comprehensive, including medication, behavioral therapy, educational training, etc. Medication is the main treatment modality, and currently there are two types of medications: psychotropic drugs and non-psychotropic drugs, psychotropic drugs are central stimulants, methylphenidate including short-acting drugs and long-acting drugs, and non-psychotropic drugs including tomoxetine hydrochloride. The most common adverse effects of medications are gastrointestinal reactions, decreased gastric intake, nausea, etc. Behavioral treatment focuses on enhancing the frequency of certain desired behaviors by praising and rewarding the child, and reducing undesired behaviors by intentional ignoring, etc. Educational training includes parent training, school intervention, and sensory integration training. Parent training is mainly to popularize the knowledge of related diseases, establish interactive and communicative parent-child relationship patterns, improve parental attention skills, and guide parents to effectively manage these behaviors of the affected children and enhance compliance and self-control. School intervention is to strengthen communication links and cooperation between parents and teachers, establish positive teacher-student relationships, help children control impulsivity, focus attention and discipline, and improve learning skills so that children can learn and maintain appropriate behaviors and change and reduce inappropriate behaviors. Synergy and cooperation between school, family and doctor help to achieve better results. Sensory Integration Training is a training program that helps children to control their body senses, increase the input of sensory information, and promote the coordination of various sensory perceptions in order to improve brain function. Sensory integration training is effective at least twice a week for an hour each time, with at least 40 sessions. Attention deficit hyperactivity disorder is a chronic disease that requires early diagnosis, early systematic and standardized treatment. Only long-term adherence to treatment and regular follow-ups can stabilize control and thus minimize the harm of attention deficit hyperactivity disorder to children.
