Did any/all of you see the Oprah MJF show last week. The always interesting Dr. Oz showed a real brain and showed us all what the Substansia Nigra or whatever looks like and how it is placed in the brain. My thought was: maybe we differ because only sections or segments of it are damaged, and in each case that would manifest itself in different symptoms?

Rosebud,
Just a quick reply and more later. I am participating in a study that is correlating structural changes in the brains of PD patients with cognitive changes, sleep apnea and alterations in sleep patterns, memory. It looks like what happens, when and how much damage to substantia nigra is critical to the function of other parts of the brain and are reflected in the behavoir of PWP. I will write more about this study later. Girija |

What Dr.Oz was showing is the part of the brain that a F-Dopa scan watches to see how much radioactive isotope attached to dopamine is used by the dark ring of cells. Pathology reports also are used to determine if Parkinson's disease was part of a cadaver's physical makeup. If only a part of the brown cells are lightening, a diagnosis of PD is still made.
The question still needs to be answered, "What caused the death of the dopamine producing neurons?" There could be hundreds of reasons for the death of these cells. How the neurons are killed is what causes the different symptoms for each person. Does this make any sence? That is how I understand it anyway. Vicky |

Vicky: you clarified my question further by stating "it is How....these cells are killed" And yes there could be a thousand ways. Which would explain the thousand different variations. I know I certainly feel like I have not lost my uniqueness in this shipload of dysfunctional persons.
Sidenote: The local PD association thought there were approx 7000 People with Pd in British Columbia, but were alarmed to find there were actually 11,000.+ and newly diagnosed stats are rising scary fast .... especiallly in the Y.O. group

Do they believe the numbers are going up because of better dx tools or because more people are getting PD, and earlier? If the latter, to me that points to environmental causes (chemicals in our food, massive vaccinations of vulnerable infants) rather than genetics...thoughts?

Well the DX tools haven't changed much. They look you over and pronounce the words PD over you, and thats about it. You don't get the more advanced "tools" (if you wish to call them that) unless you have lots of money to blow, complain long and loud for a further look or get into some sort of study with benefits. Do I sound cynical? Must be cuz I am.
