Sorry to have taken so long. I was most impressed with the presentation on Deprenyl. I felt the doctor explained the situation very well and in a manner that could be understood by most of us. He explained that Deprenyl blocked the oxidation of the dopamine producing cells and thus retarded the progression of the disease. He had been part of a study with 800 participants. The overall results of the study indicated that Deprenyl-Eldepryl does slow the progression of PD and he uses it in his patients. He even talked about the British study that indicated a higher mortality. His response was that they had look at many other studies done worldwide and did not find any increased mortality. He also reviewed their list of 800 and found not only was there no increase, but in fact there was a decrease. He felt that maybe the older age of the participants in the British study might have contributed to the increase. I was so impressed by his findings that I am very relieved that Fuad has been put back on the drug. I hope I have not misrepresented any of the facts, but I tried not to get to technical.
