The researchers, from the Mayo Clinic, in Olmsted County, Minnesota, examined the medical records of everyone in Olmsted County who developed Parkinson’s from 1976 to 1995.
They found the highest levels of Parkinson’s disease in people with nine or more years of education. The degree of risk was seen to rise with additional years of schooling.
Among a range of occupations, physicians were most at risk, while people in active, manual jobs, such as construction and factory workers, had the lowest risk.
No clear explanation for the trend has yet been found. But previous Parkinson’s research has shown that regular exercise can protect against the disease, and, for those already affected, slow its onset. Researchers theorise the risk of Parkinson’s may be higher in people with sedentary occupations
Ummm, the “years of study” were nine? In Olmsted County, Minnesota? That would be 9th grade.
The researchers examined medical records of people in ONE county who had been diagnosed with Parkinson’s. They didn’t take all people in the county and examine them to see if they had Parkinson’s.
So, what they found was that, of the people who had access to medical care in Olmsted County AND who had already been diagnosed with Parkinson’s, there was an association with higher education.
Duh! In the US, there is an association between having medical care and income, and there is an association between income and education. Of course, there would be fewer pre-9th grade drop-out manual laborers being diagnosed with Parkinson’s, because those sorts of people don’t go to doctors unless things are far advanced and desperate. Unlike the UK, they cannot afford to go to doctors. They have no insurance.
And who would be most likely to identify early signs of Parkinson’s in themselves and self-diagnose and seek care for it? Or an explanation? Those with higher education, particularly physicians.
Well, I’m sure they adjusted for all that.
I think it more likely that there is an association with lutefisk. Minnesota, you know. Hmmm, I wonder did they say anything about an association with membership in the Sons of Norway . . .
