Dear M.Dawn, you raise important questions around the impact of stress on PD, and by extension perhaps the impact of stress on the overall rate of progression of PD. >I know that stress can definitely make PD symptoms worse. I came across a recent article where moment to moment variability of hypokinesia (measured through spontaneous eye blink rate) was clearly impacted by exernally applied stressors. It explored this effect in a marital context which to my way of thinking makes the study more relevant by virtue of looking at the impact of stress on current functioning in a virtually real life situation. An extended value of this study is to draw attention to variability of presentation of PD across the day AND how stress can impact on that presentation. The study looked at interpersonal stress but I think we could all agree that it is a simple extension to seeing internally generated stressors (grief, anger, anxiety, etc.) as also contributing to variability of functioning. This will happen with most everyone and with PD it has particularly potent effects. >Can this work in the opposite way? Why not? Or put differently, of course. The structure of experience is bipolar. We often tend to attach to only one end of the polarity and then we are shocked when something else happens which doesn't fit with our model of the universe. (A bit philosophical but nevertheless very real.) Recently you posted to the list and mentioned that good things were happening to you over the past few months. Why would we not also presume that those experiences had a cumulative impact on you and also on the status of your PD, and possibly also on the rate of progression of your PD? Going back to the article re eye blink and stress, the key finding was the moment to moment variability of hypokinesia; if (-) stress contributed to the hypokinesia, could we not also say that eustress ( + stress) contributes to the presence of movement. (This needs to be explored since it is also possible that the absence of negatively perceived stress may be sufficient to block the hypokinesia, which is a bit different.) Now that was just momentary variabilities. Why not look at that as all being cumulative - a good cycle in essence feeding on itself. This raises the whole question of rate of progression of PD. I am just starting to explore that in the literature ( and am very receptive to input from anyone). This seems to me to be of the essence of your question. We all know the mantra which goes "PD is a progressive neurological disease..." Perhaps the mantra can be alternated with "PD is a neurological disease with variable rates of development..." ...the psychological factors affecting rate of progression are to be discovered by each person in their unique situation. How do you like those apples? How about another mantra? "PD is influenced by the presence or absence of Dopamine in the brain and as the brain cells in the substantia nigra die off there is less...." With "Our brains sit in a soup of neurotransmitters which interact with one another, one influencing another depending on, among other things, expectations and mood states, etc." Perhaps others can add and fine tune the + and - mantras. J.R. Bruman drew our attention to a similar line of thinking in his posting of 6/11/98 entitled Depression and PD. He cites fascinating research which clearly shows the relationship between behavior and emotional state and level of available dopamine. To me this is yet again another way of saying that there is tremendous potential for exploring non -pharmacological events and their impact on the presentation of PD in an individual. >Being with both of the doctors was a very postive experience for me. Let me emphasize the words "very positive." You said that you have the type of PD characterized by rigidity. Hypokinesia also? Weaving my story now, the backdrop to both visits is a series of postive experiences and presumably a sense of well being developing over the summer - that's the ground - and the heightened expectations and sense of ease of being with those two people -that's the immediate field (+ stress), combined to create a "soup" in your head/mind/body which was favorable to ease of movement. The backdrop creates the general state and if it is positive (favorable) it will help to raise expectations (of possibilities, of hope, etc.) and also increase our resiliency. >Have any of you improved at times which are emotionally very good for you? I have only seen one response so far (Barbara Rager, 9/4/98 and I totally agree with her). Perhaps you have received other responses back channel. There is such volume on this list that people must pick and choose what they respond to, but this appears to be a vitally important question. >a friend who was with me at Mayo has (I believe) misunderstood and now is rather convinced that I don't have PD. Perhaps since the both of you are "studiers" you could engage her is a search to further explore this issue of wellness and its impact on the rate of progression of PD, etc. It may be valuable and interesting for you to monitor your level of rigidity/hypokinesia during the time that you are "under the influence" of this tension with your friend. My expectation is that you will become more rigid, less flexible/creative in your mind, etc. To resolve this issue is to move back again into the other positive state you have been in all summer. Good luck! Thank you for raising these questions and for giving me the opportunity to begin to share some of my thinking on these matters.
