A study proved that antihypertensive patients have lower risk of Alzheimer’s disease. The study was appeared in the journal Plos Medicine.

The scientists analysed the genetic data from 17,008 individuals with Alzheimer's and 37,154 people without the disease. The team looked for links between Alzheimer's disease and a number of health conditions including diabetes, obesity and high cholesterol. But they only found a significant association between higher systolic blood pressure and reduced Alzheimer's risk.

"It may be that high blood pressure is protective or it may be that something that people with high blood pressure are exposed to more often, such as antihypertensive medication, is protecting them from Alzheimer's disease," said co-author Paul Crane, associate professor of internal medicine at University of Washington.

"This is to date the most authoritative paper looking at causal relationships between Alzheimer's disease and these potentially modifiable factors. In terms of the number of samples, it can't get bigger at this point," Kauwe said.
