People with hypertension between ages 35-44 more at dementia risk, a recent study shows. The researchers studied how age at high blood pressure (HBP) diagnosis is associated with brain volume and dementia risk.
It found that people with hypertension diagnosis between ages 35 and 44 are 61% more at risk of developing dementia than those without HBP.
The World Health Organization (WHO) states that HBP, or hypertension affects around 1.28 billion people aged 30–79 worldwide.
HBP is the leading cause of cardiovascular disease and premature death worldwide. It is also associated with risk factors such as diabetes, depression, and dementia.
In a recent study, researchers from China and Australia investigates how the age of hypertension onset affects brain health and the risk of developing dementia.
The researchers concluded that individuals diagnosed with hypertension between ages 35 and 44 had a 61% higher risk of developing dementia compared to those without hypertension.
The authors published their study in the journal Hypertension.
People who were diagnosed before age 35 were at an 80% higher risk, while those diagnosed between 45 and 54 were at a 45% higher risk.
“However, it is generally believed that interactions between
several pathologic factors are most likely responsible. Importantly,
hypertension may result in structural and functional alterations in cerebral
vessels, such as atherosclerosis, vascular stiffness, vascular remodeling, and
impaired cerebral blood flow circulation and regulation,” Dr. Simin Mahinrad, a
research assistant professor at Northwestern University’s Feinberg School of
Medicine in Chicago, IL. He was not involved in the study.
