The risk of Alzheimer’s disease could escalate along with high blood pressure, according to a new study.Published in the medical journal Neurology, the research found that people age 60 and older who have untreated high blood pressure may be more likely to develop the common dementia type.Although the results don’t prove that untreated high blood pressure causes the disease, they do show an association, the American Academy of Neurology stated in a press release.ALZHEIMER’S AND PARKINSON’S RISK IS HIGHER FOR PEOPLE WITH BODY FAT IN TWO SPECIFIC AREASStudy author Matthew J. Lennon, M.D., PhD, of the University of New South Wales in Australia, wrote in a statement that high blood pressure is a “leading cause of stroke and cerebrovascular disease, and yet it can be controlled with medication, reducing a person’s risk of these diseases.” The study found that people age 60 and older with untreated high blood pressure may have an increased risk of Alzheimer’s.

(iStock)Factors like socioeconomic status, health literacy, access to medications, poorly managed medical conditions, and depression and other mental illnesses could also confound the association between hypertension status and dementia risk, Lennon added.”Because the study is taken over a long period of time, any number of outside variables can alter the results, making it less reliable,” Landsverk noted.CLICK HERE TO GET THE FOX NEWS APPHypertension is extremely common, affecting two-thirds of those over age 65 and around 1.3 billion people worldwide, Lennon noted. “In the vast majority of cases, it is clinically silent, causing no symptoms until you present with a heart attack, a stroke, or — as we now have shown — dementia,” Lennon said. Hypertension is extremely common, affecting two-thirds of those over the age of 65 and around 1.3 billion people worldwide.
