The brains of middle-age adults may be ageing prematurely if they have obesity or other factors linked to cardiovascular disease, new research has found.
Almost one-quarter of adults have metabolic syndrome, a set of factors that in combination amplify a person's risk of heart disease, diabetes, stroke and other illnesses. In the new research, participants were considered metabolically unhealthy if they had two or more such factors: high blood pressure; high blood sugar; high blood triglyceride levels; or low levels of HDL, the "good" cholesterol — or if they took medicine for diabetes, high blood pressure, or cholesterol.
