Do age-standardised dementia incidence rates really increase in England and Wales?

Abstract

Yuntao Chen and colleagues analysed data from the English Longitudinal Study of Ageing (ELSA) across 2002–2018, revealing a U-shaped trend in dementia occurrence.1 Their findings indicate that age-specific dementia rates initially declined from 2002, and began to rise around 2008. However, a commentary by Nichols and Lee raised the possibility that the upward trend might be due to methodological issues.2
