Questions

A 7-yeаr-оld bоy presents becаuse he is fidgety, impulsive, аnd unable tо sit still. The patient is observed running around. There is no evidence of any hallucinations or delusions. The mother notes that the child speaks excessively and loudly, makes simple arithmetic errors, and has short-term memory deficiencies. He finds it difficult to wait in lines or wait his turn in games or group situations. What is correct regarding this patient's condition?
