MRCP2-3444

A 65-year-old man returns to neurology clinic for review with his wife. He was diagnosed with Parkinson’s disease three years ago and was started on ropinirole nine months ago as his symptoms were becoming difficult to manage. He was mainly concerned with the rigidity of his movements. Since then he has improved remarkably, and his movements are much better, with reduced rigidity on examination. His mood has also been improving with the relief from his symptoms.

However, his wife has become concerned that he has been increasingly spending large amounts on shopping, something which he has not done before and that she feels is out of character. What is the most likely explanation?
