Physicians currently do not have available rigorous treatment options that change the natural course of dementia. However, if and when interventions to prevent, delay, or cure dementia become available, then early identification will become more important. Cognitive screens of increased sensitivity, specificity, positive predictive value, and negative predictive value that can be easily and quickly administered in a variety of clinical settings will be paramount. From population health and economic perspectives, in order to do the most good for the greatest number of people, economically viable screening methods must be developed. These might include, for example, cognitive screening examinations rather than expensive neuroimaging or serum analysis. [23]
