My name is XXXXX XXXXX I am a General Specialist. I have done some research and have found a Professor Lindsay Simon MD, who Has been practicing and teaching at the National Hospital for Nervous Disease, at Queen Square, London, England: http://www.uclh.nhs.uk/OurServices/OurHospitals/NHNN/Pages/Home.aspx. This may be a great starting point to locate her. I found where she had done a Fellowship training with a Doctor in NY City: You can read his Bio and see where he had trained with her:
