Use of Lipid-Lowering Agents, Indication Bias, and the Risk of Dementia in Community-Dwelling Elderly People

While the possibility of indication bias in the original observations cannot be excluded, it was not demonstrated in LLA use in this study. Lipid-lowering agent use was associated with a lower risk of dementia, and specifically of Alzheimer disease, in those younger than 80 years. Further research is warranted.
