Healthy Cognitive Ageing Project

This is a sub-study of the main ELSA study, looking at how memory and cognition changes as people age. It is based on a similar study carried out in the United States in 2016/17 by ELSA’s sister study, the Health and Retirement Study (HRS). Further similar studies are planned around the world.

The aim of the study is to understand more about changes in cognition as people age, and about the prevalence of mild cognitive impairment, dementia and Alzheimer’s disease among the over-65s in England, and in comparison to other parts of the world.

Fieldwork took place in early 2018, with a sub-group of ELSA participants aged 65 and over selected to undertake a series of cognitive assessments during a face-to-face interview. A total of 1,274 face to face interviews will take place. Participants will also be asked to nominate a family member or friend to undertake a short paper self-completion or telephone interview to provide information about changes in the participant’s memory and cognition and the activities they do inside and outside the home.

Information for ELSA participants who have been invited to take part in the study is available at
