This is probably too complicated for most of us (certainly above my pay grade), but I thought it was pretty cool:

. Now for the first time ever, researchers at the Luxembourg Centre for Systems Biomedicine (LCSB) at the University of Luxembourg have published an interactive picture containing the current knowledge about the underlying genetic and molecular causes of Parkinson's disease. This "Parkinson's disease map," or "PD Map"

Marek Ostaszewski sums up the most important benefit of the PD Map: "By uniting the existing knowledge about PD, the map sheds light on the connections between pieces of the puzzle nobody had thought existed - and which will form the basis for brand new research hypotheses." To the biological scientists the PD Map helps pinpoint the gaps in our current understanding of Parkinson's.

The other cool thing about this project is that the researchers are making it open-source like WikiPathways.

Tupelo3,

Thanks for finding this.

You write:

You do yourself a disservice: ask for a pay rise!

I played with it briefly. It was interesting following the links in the network. It's still early days, but it could grow into something important.

I've proposed in the past producing a belief network showing the linkage between any two factors involved in PD

Correlations could be used. They're not perfect: correlation does not imply causality and correlation is not transitive (A is positively correlated to B, and B is positively correlated to C, does not imply that A is positively correlated to C). Nevertheless, it would be interesting.

Can someone add to this?

did smoke ----> get PD ++++> constipation

A bonus mark to someone who can find a contradiction.
