Fascinating study.
One reason there are not enough resources devoted to PD. It is under-reported:
…”the proportion of PD sufferers whose death certificates made no mention of the disease ranged from 68% in Iceland to 81% in Rochester; and 2) in those cases where PD was reported, the annual proportion recorded as the underlying cause of death in Sweden ranged from 46% to 81%, and varied by county…..”
…”excess mortality registered in many towns in Catalonia, the Basque Country, Huesca, Asturias and Tarragona is consistent with the traditional, well-documented industrial toxic emissions reported in these places….. emissions from multiple industrial plants near the city of Tarragona, in which lead, cadmium and other organic and inorganic industrial chemicals are included…”
(and yet there are other towns with the same level of pollution, but lower than average PD)
There was a similar map of the USA somewhere here on Neurotalk – showing the frequency county by county
And this north-south thing – northern spain has a lot more PD than southern Spain. In Canada, there is a high rate of PD among the Inuit in the Arctic.
Whassup with that, doc?
