Review Question - QID 215153

A 7-year-old girl is brought to her pediatrician because her parents are concerned that she is doing poorly in school. Specifically, her teacher says that she appears to "zone-out" in class and does not engage with other children. Furthermore, her teacher has noticed that she is very fixated with cups and will flip them over repetitively during the course of the day. Her teacher says that she is very intelligent and gets perfect scores in subjects she enjoys such as mathematics. However, it is very hard to engage her in other topics. Her parents are afraid that she has not adjusted well to their recent move to a new school district. What is the most likely diagnosis for this patient?
