Madelyn,
Many thanks for your input, putting the alternative, or contradictory evidence on the effects of taking statins.
Like you, I am not recommending what people should take. I am just trying to assemble all the evidence I can find relating to the BBB. Maybe the conflict of whether statins improve or exacerbate the symptons of PD depends on which statin you use. The researchers from Boston University found Simvastatin gave the best improvement in PD. Do you know which statins the 3 people you mention who had adverse effects? Possibly atorvastatin or lovastatin? I have not yet been able to find what effect these other statins have on the BBB.
Thanks again for the terrific amount of work you have posted on the topic.
Best wishes
Ron
