The research applied these risk factors, which include metrics such as high blood pressure, to cardiovascular data collected from 7,899 British men and women at age 50 in the Whitehall II Study, which is looking at the impact of social, behavioural, and biological factors on long term health.
Participants were free of cardiovascular disease and dementia at age 50.
Dementia cases were identified using hospital, mental health services, and death registers until 2017.
Of the 7,899 participants, 347 cases of dementia were recorded over an average follow-up period of 25 years. Average age at dementia diagnosis was 75 years.
