Direct answer

What are the signs of ADHD in children?

Signs of ADHD in children include difficulty staying focused, frequently losing things, not following instructions, fidgeting, difficulty staying seated, talking excessively and acting without thinking. To be clinically significant, they must be more marked than expected for the child's age, present in more than one setting and cause impairment.
