Will the child’s physical development be affected? What are the risks of ADHD for children? ADHD has little impact on physical development, but it has a very significant impact on the child’s psychology and behavior. On the one hand, these children have poor attention span, which directly affects their schooling; on the other hand, they do not go through the brain, are mentally young, have poor emotional control, are prone to conflicts with others, and affect interpersonal communication. Moreover, ADHD continues into adulthood and can lead to dangerous behaviors such as drug abuse and crime, which can be harmful to the growth of the individual and society. Does ADHD affect my child’s intelligence? ADHD does not directly affect intellectual development, but because the core symptom of ADHD is poor attention span, and because children are at the peak of their intellectual development, poor attention span can lead to children not remembering knowledge and not having the patience to learn, resulting in a lower level of presented intelligence. On the surface, the condition seems to be due to the disease affecting the child’s intellectual development, but in reality it is only because the child’s attention span is affected and his or her ability to learn knowledge is limited.
