When using cognitive screening instruments (CSIs) there is always a balance to be struck between test sensitivity and specificity, with the chosen test cut‐off being determined by the needs of the particular clinical situation. Dr Larner investigates whether there is a trade‐off between CSI diagnostic accuracy and administration time, or, in other words, whether shorter CSIs are less accurate than longer ones which may sample more cognitive domains and/or in greater depth.
