Prognostication in dementia.

Dementia is a progressive, irreversible illness and leading global cause of death defined by cognitive and subsequent functional decline. Current treatments have limited impact on mortality. In this chapter, we discuss the trajectory of dementia and its variability, markers associated with poorer prognosis (such as poor nutrition, pneumonia, comorbid conditions), the impact of hospitalization on prognosis, and current models of end-of-life palliative care/hospice eligibility (with the use of the Functional Assessment Staging tool and other markers). We then discuss strategies to discuss prognosis with patients and their healthcare proxies using a mental model (Ask, Discover, Anticipate, Provide, Track: ADAPT) and specific skills. Because of progression of dementia variability, prognosis is better discussed in terms of function. For patients with dementia, initiating advance care planning earlier in their disease course allows for more patient involvement (such as to identify a surrogate decision maker).
