This chapter discusses dementia, memory loss, and other cognitive dysfunction. Dementia is diagnosed when cognitive or behavioral symptoms interfere with the ability to function at work or at usual activities. This represents a decline from previous levels and is not explained by delirium or major psychiatric disorder. The criteria for dementia include a minimum of 2 of the following cognitive or behavioral impairments: 1) impaired ability to acquire and remember new information, 2) impaired reasoning and handling of complex tasks, 3) impaired visuospatial abilities, 4) impaired language functions, and 5) changes in personality, behavior, or comportment.
