Late-Onset High Blood Pressure May Stave Off Dementia
Numerous studies have shown that high blood pressure, or hypertension, is a risk factor for dementia. However, according to new research, hypertension may actually lower dementia risk in older adults.
A recent study examined the link between high blood pressure and dementia in people over the age of 90. Researchers assessed study participants—who had not been diagnosed with dementia—every six months for 2.8 years. At each assessment, neurological and neuropsychological examinations were performed and blood pressure measurements in medical records were reviewed.
According to researchers, people diagnosed with hypertension between the ages of 80 and 89 had a significantly lower risk of dementia than people with normal blood pressure. The lowest dementia risk was seen in people diagnosed with high blood pressure after the age of 90. This is the first study that showed this association and more research is needed.
