Is plasma cholesterol related to cognitive decline in hypertensive individuals?

Hypertensive patients have cognitive decline, possibly related to cerebrovascular alterations and Alzheimer`s disease. In addition, it is described a positive relationship between high serum cholesterol levels and cognitive impairment. However, the impact of hypercholesterolemia on cognitive function in hypertensive individuals is not described. Thus, this study hypothesizes a positive relationship between plasma cholesterol concentrations and decreased cognitive function in hypertensive individuals.
