Higher levels of total cholesterol (TC) and low-density lipoprotein cholesterol (LDL-C) are associated with a decreased risk for Parkinson’s disease (PD) in men, a large observational study shows.

Just my luck – my total cholesterol has always been low, even though recently my HDL has been a high percentage of LDL and total cholesterol.

261,638 persons aged 40 to 79 years not taking statins.

…followed from baseline to death, end of study, or PD diagnosis.

From annual blood tests, researchers collected information on levels of TC, LDL-C, and high-density lipoprotein cholesterol (HDL-C).

They categorized TC levels into upper (210 mg/dL or more), middle (180 to 209 mg/dL), and low tertiles and LDL-C levels into upper (140 mg/dL or more), middle (110 to 139 mg/dL), and low tertiles.

Among men, compared with low levels, middle and upper levels of TC and LDL-C were significantly associated with lower risk for PD.
