Renal failure is significantly associated with an increased risk of Parkinson's disease

The research article entitled ‘Association between kidney function and Parkinson's disease risk: a prospective study from the UK Biobank’ explores the potential link between kidney function and the risk of developing Parkinson's disease (PD). The study is based on a cohort of 400,571 participants from the UK Biobank, a vast epidemiological database. The researchers used the estimated glomerular filtration rate (eGFR) as an indicator of renal function, calculated from creatinine and cystatin C levels in serum. The aim was to examine whether renal insufficiency, as measured by a reduced eGFR, could be associated with an increased risk of PD.
