To all listmembers, Since posting the abstracts on personality a few days ago, there has been a lot of discussion on the list about this subject. Certainly, debate is a good thing, and many of the responses I received were thoughtful and eloquent, but a few (not many,but some) were quite angry and seemed to be personally directed against me. So I'd like to say a few more things. (If this isn't risk-taking behavior, I don't know what is!) First of all - I did not write these articles; I didn't conduct the research; I'm not a psychologist, and I wasn't attempting to promote a certain point of view. Another list member asked if anyone knew of literature on a "Parkinson personality" and I answered her question, and copied the abstracts of some articles I had in my files. I also added my reactions to the articles and posed some "what if" questions that came to mind after re-reading them. I find it fascinating to read about human behavior and the influences that form our personalities, and thought others might be interested too. I never meant to imply that every PWP has the same personality traits. As I said in my original posting, "Of course while many of us may fit the profile, there are probably just as many others who don't." No group of people should be stereotyped. I would never defend such a practice, and I don't believe that was what these researchers were trying to do either. The disadvantage of seeing only an abstract is that so much is left out. If you read the entire article, the authors do discuss many of the same issues that were brought up in your replies. There has been much research in recent years on brain chemistry, and there is some evidence that it can produce tendencies for certain traits and behaviors. But these tendencies are of course influenced by many other factors - our parents and upbringing, social influences, the environment, and living with a chronic disease. I do think it is important to understand how all these influences work and interact, including how decreased levels of dopamine may affect us in all ways, whether premorbidly or not. Maybe we don't all agree with the theories presented in these articles, but who knows - perhaps this type of research will add another piece to the PD puzzle. I am facing similar challenges as everyone else. I feel anger too - anger about having this disease,at insensitive medical personnel,at people who patronize me,at a government that moves too slowly,or just doesn't care. But what good does it do for us to be angry with each other for sharing information (even if it is controversial),or for expressing a differing opinion? Peace, Linda Herman
