This document presents a case study of a 15-year-old client diagnosed with Asperger's syndrome and anxiety. Cognitive behavioural therapy was used to address the client's social anxiety. Over the course of treatment, the client's anxiety symptoms decreased, communication with his family improved, and he was able to independently engage in social activities like shopping and playing pool. The therapist reflected that focusing more on psychoeducation about Asperger's syndrome and behavioural experiments earlier in treatment may have led to even better outcomes for the client.
