Sclesinger Associates are a marketing research compnay. The questions were about my symptoms, what medications I take, my diagnosis, what treatment options was I offered, why did I choose Tysabri, was it my choice or my neuro's choice and my experience in receiving it. I was asked to describe the day I received the medication, what happened before, during and after. There was no mention of Biogen/Elan, any other company, etc. Short simple questions and a thank you.
