WP1 Longitudinal and economic analysis

The English Longitudinal Study of Aging (ELSA) began in 2002 with 11,391 members aged 50-100 years. The sample is reassessed every two years on a range of cognitive processes and lifestyle and health factors. Emerging findings from the database suggest that dementia risk is positively related to loneliness, while having a number of close relationships and being married later in life is inversely related. Other identified factors associated with increased risk include hearing/vision loss and slower walking speed. Reduction in physical activity after diagnosis is also associated with accelerated cognitive decline and maintaining physical activity may reduce symptom progression in dementia.
