I do remember when this study came out last year there were two issues that needed clarity: determining if there was an actual causal relationship; and the fact that all but one of the patients were tobacco smokers also (which are actually related issues).

Nevertheless, there's always something to deal with..... the choices PwP have to make never seem easy..... I'm not at that point yet, but I would imagine if one's symptoms become bad enough, treatment decisions involving risk of some sort have to be made.
