A worried mother brings her 4-year-old son in to the GP surgery, reporting that he has had a change in behaviour

A worried mother brings her 4-year-old son in to the GP surgery, reporting that he has had a change in behaviour. She tells you that he is normally a very happy, responsive child, but over the past few months has been quite rude, ignoring instructions both at home and at school. His teacher raised concerns that he prefers to play alone and often will not engage when asked questions in the classroom. She is concerned that his speech is not developing as well as his peers. Otherwise, he has reached his other developmental milestones and is generally well aside from an ear infection a few months ago.
