The increasing incidence of dementia-type problems is a growing concern for our aging population, and early diagnosis is important to best manage its potentially devastating effects. Screening is routinely used in dementia assessments. However, limited research has been conducted in New Zealand regarding whether we are using the most appropriate screening in the most appropriate way for the local population. Ms Strauss investigated these issues through two projects. The first was an online survey of clinicians’ approaches to screening, their requirements, and their favourite screening tests. The second was a retrospective quantitative study comparing the performance of three commonly used screens. Results showed that the Addenbrooke’s Cognitive Assessment-Revised (ACE-R) is the most suitable screen in terms of diagnostic sensitivity, specificity, and meeting other clinician needs. Ms Strauss recommends that cut-off scores for the New Zealand population be different to those used by the ACE-R’s international authors.
