Takeaway
In a South Korean population study, those with lower high-density lipoprotein cholesterol (HDL) and greater variability in HDL have a higher incidence of Parkinson’s disease (PD) over 5 years.
Why this matters
While the benefits of HDL extend beyond the cardiovascular system, the association with PD risk is uncertain; this country-wide cohort study indicates there may be a link between HDL and PD risk.
