I have had PD for about 5 years. Have passed me well most of the time. During this autom, I began to get worse again, I got dizzy and it was harder to remember things. For a while I thought that I could not continue working as the principal of a school. During the autom, I was working in a research on PD. In this study, they look at the relationship between PD and the cognitive, our thinking. During a visit with my PD doctor I got a new medicine, Azilect. This medication has helped me so well that I feel a big positive improvement and the cognitive functions are much better. I'm glad I join this study but wonder why I did not receive this medication early.
