Hi..I think she needs psychiatric as-well-as neurological consultation. As post-stroke depression is a common presentation and she has other co-morbidity like mitral valve prolapse
, so cardiological issues also need to be addressed as the choice of medication should also be judicious in case of such illness. So please consult a cardiologist
, then a neurologist
for her post-stroke neurodeficit & then a psychiatrist
for her mood problems. Have a good health.
