Psychiatry 10

An 11-year-old boy is brought to the psychiatrist by his mother for an evaluation as mandated by his school. The patient was recently suspended from school and will not be allowed back until he is evaluated by a psychiatrist. The mother is interviewed alone, and the patient is asked to wait in the waiting room. His mother reports that there has been a series of incidents at school where other children have accused her son of bullying them. The patient has had behavioral troubles in school since kindergarten where he would get up out of his seat and walk around class pinching other children. She reports that her son is a “very intelligent” boy who “refuses to apply himself” in his studies. He has always had difficulty completing assignments on time, remembering to turn in assignments, and has resisted doing homework. She reports that the patient is prone to violent outbursts where he screams at his mother and that he recently threatened her with a kitchen knife when she attempted to set boundaries. The last time mother cleaned his room she noticed that he had several pairs of sneakers that she did not purchase for him.
