Marcum ZA, et al. - Researchers assessed the correlation between high-density lipoprotein cholesterol (HDL) and non-HDL-C levels at specific ages and subsequent Alzheimer's disease (AD) risk. Modestly higher risk of AD was seen in the people with low (120 mg/dL) and high (210 mg/dL) non-HDL-C levels during their 60s and 70s vs those with intermediate (160 mg/dL) levels. Small sample sizes were seen in the extreme age bands (50s and 80s). Findings did not suggest a statistically significant association between HDL-C and AD risk.
