Anne and list: Each time I (and anyone else in the study) go to Philadelphia for an appointment to see the study Drs., I am examined and the results recorded to be checked against prior examinations. Some of the tests (for example those which are timed), are subjective. Some, however, are objective and are therefor subject to all kinds of bias, intentional or not. It is why there are two Drs. examining and forming opinions independently. All the foregoing is a roundabout way of getting to your question of discussions with other study participants. The answer is no, because we are specifically asked not to do so to avoid subjective bias. If you know I feel better then you might think that you are as well and answer questions put by the Drs. accordingly. might even be that I shouldn't have revealed my progress to the list public at large since there are certainly study participants on the list. I did it purposefully because I thought it would give more list members some food for thought with regard to attempting to join the study. Paul H.
