The case story of a 47-year-old man with advanced rectal carcinoma illustrates the professional services and care system strategies available to help clinicians serve patients coming to the end of life. For this patient, who understands his prognosis, primary care physician services include (1) prevention and relief of symptoms, (2) assessment of each treatment before and during implementation, (3) ensuring that the patient designates a surrogate decision-maker and makes advance plans, and (4) preparation of patient and family for the time near death. ⋯ Function and symptoms for those living with serious chronic illness at the end of life generally follow 1 of 3 trajectories: (a) a short period of obvious decline at the end, which is typical of cancer; (b) long-term disability, with periodic exacerbations, and unpredictable timing of death, which characterizes dying with chronic organ system failures; or (c) self-care deficits and a slowly dwindling course to death, which usually results from frailty or dementia. Effective and reliable care for persons coming to the end of life will require changes in the organization and financing of care to match these trajectories, as well as compassionate and skillful clinicians.

Alzheimer disease (AD) represents a major and increasing public health problem. If populations were identified with significantly lower or higher incidence rates of AD, the search for risk factors in the genesis of AD could be greatly enhanced. ⋯ This is the first report of incidence rate differences for dementia and AD in studies of 2 populations from nonindustrialized and industrialized countries using identical methods and the same group of investigators in both sites. Further explorations of these population differences may identify potentially modifiable environmental or genetic factors to account for site differences in dementia and AD.
