AAIC 2023 | A single question dementia screening method

Xin Xu, PhD, School of Public Health and The Second Affiliated Hospital of School of Medicine, Zhejiang University, Hangzhou, China, discusses an investigation into a stepwise dementia case-finding approach based on an initial single question assessment. Community-based screening efforts can be hindered by the time commitment necessitated by the large elderly population in China. Dr Xu therefore investigated the time-effectiveness and discriminant validity of a single question case finding approach. Participants were asked the Progressive Forgetfulness Question (PFQ), with anyone answering ‘Yes’ completing further testing, including the MoCA, MMSE, or AMT. The PFQ showed a negative predictive value of 94.2%. In this way, many low-risk individuals could be immediately ruled out, decreasing the number of people requiring further evaluation. Overall, this approach could be valuable to minimize time and resources in community-based settings where these assets are limited. This interview took place at the Alzheimer’s Association International Conference® (AAIC) 2023 in Amsterdam, Netherlands.
