The risk of being diagnosed with Alzheimer's disease is about a third higher for seniors who have untreated high blood pressure, new research suggests.
READ MORE: The five vital health numbersA condition suffered by nearly half of all Americans raises their risk of Alzheimer's disease, a study suggests.
It causes damage to blood vessels, restricting blood flow and oxygen to the brain and depriving it of its ability to clear out toxic protein buildup which is a hallmark of Alzheimer’s. Researchers at the University of New South Wales in Australia combined data from 14 unique studies encompassing 31,250 people from a range of countries, including Australia, Brazil, China, France, Germany, Greece, Italy, Japan, Korea, Nigeria, Republic of Congo, Spain, Sweden, and the United States.
They found 9 percent had untreated high blood pressure, 51 percent were taking blood pressure medications, 36 percent did not have high blood pressure, and 4 percent were noted as uncertain. ‘These results suggest that treating high blood pressure as a person ages continues to be a crucial factor in reducing their risk of Alzheimer’s disease.’
When a person’s blood pressure is consistently 130/80 mmHg or higher, a doctor will typically diagnose them with hypertension.
