What is the difference between a child being lively and energetic and ADHD?

Patient's question:

The difference between a child being lively and hyperactive and ADHD

Doctor's answer:

1、The activities of children with ADHD may be aimless and often unfinished, whereas the hyperactivity of normally lively children is usually motivated and goal-oriented.???
2、The behavior of children with ADHD is often impulsive and without regard for time or consequences. What is the difference between lively children and children with ADHD? It is that the former acts in certain situations and disregards the consequences, lacking self-control. In contrast, normally lively children, constrained by time and place, exhibit some self-control.
3、Children with ADHD often ignore the advice of teachers and parents, acting contrary to what is said. On the other hand, normally lively children tend to improve after being inspired and educated.
