Uncontrolled high blood pressure increases the risk of stroke and other conditions. The key word is uncontrolled, because high blood pressure is treatable and in so doing reduces risk of disease including Alzheimer’s. A multination analysis of more than thirty thousand older people was published in the journal Neurology. Even after correcting for variables such as age and gender, researchers report those with untreated high blood pressure had thirty-six percent greater risk of Alzheimer’s disease compared to people without high blood pressure. Authors say results of the study say the association between high blood pressure and Alzheimer’s suggest treating high blood pressure as a person ages continues to be a crucial factor in reducing their risk of the disease.
