Counting dementia: There is no one "best" way.
The growing societal and individual burden of dementia means that counting the cases of dementia is critical. There are several approaches and methods that can be used to identify dementia cases. The ascertainment can range from very detailed characterization of the individual (deep) to a brief standardized assessment (wide) that emphasizes individual functioning. The choice of going deep or wide depends on the goal of the ascertainment. These goals are discussed, as well as the emerging issues that may change the way dementia cases are classified.
