Just out in PLoS Medicine, a study from Alastair Noyce on the interplay between body mass index (BMI) and risk for Parkinson’s disease. This uses a genetic technique called Mendelian randomisation to test whether there is a causal link between two areas of biology. Fascinatingly Alastair’s results suggests that increased BMI is associated with a reduced risk of Parkinson’s, although what underlies this link isn’t clear and there are significant health implications of raised BMI beyond PD. A very thought provoking piece indeed.
