With aging populations and growing life expectancy, the number of people suffering from dementia is increasing. For more effective dementia prevention, it is important to better understand risk and protective factors affecting late-life cognition. It is known that midlife cardiovascular risk factors are associated with weaker late-life cognition (memory and other information processing skills). A new study from the University of Helsinki and the University of Turku aimed to examine if educational background affects this association. More than 4,000 Finnish twins participated in the study published in Age and Ageing.
