A pharmacist collected data in an active geriatric outpatient program on 140 patients admitted consecutively over a 1-year period. Compliance was monitored by patient statement, pill counting, and daily written record-keeping of all medications with the help of a pocket diary provided in the program. Weekly pharmacist counseling sessions were then initiated for all patients. After four compliance sessions, two subgroups of patients were identified: 120 compliant patients and 20 patients showing persistent 50% noncompliance. Patients were interviewed by a psychiatrist to develop a profile of the noncompliant patient. This profile may be useful in identifying other noncompliant geriatric patients. Early recognition of this special group of patients in need of directed counseling may help reduce medical misjudgment in prescribing for the frail elderly population.

A nutritional study of 100 patients enrolled in an active geriatric outpatient teaching program was conducted to document the clinical impression of weight loss in Alzheimer's disease. All new patients were asked to complete a questionnaire on nutrition. Patients were evaluated by a geriatrician, then categorized using DSM-III and NINCDS-ADRDA criteria. There were 34 Alzheimer patients and 60 nondemented patients with an average weight of 56.2 kgs and 66.1 kgs, respectively (p < .002). Of the Alzheimer group, 44% reported weight loss in the past five years compared with 37% of the nondemented group, despite a concomitant increase in food intake in 35% versus 7%, respectively. On a one-year follow-up, 92% of Alzheimer patients lost weight, whereas 57% of the nondemented patients actually gained weight. The increase in reported food intake, with a significant concomitant weight loss, raises some challenging questions as to the existence of a hypermetabolic state in Alzheimer's disease.

Alzheimer's disease affects an estimated 2 million elderly in the U.S. and challenges primary care physicians to assist caregivers in dealing with the daily management of these patients. To support the clinical observation of weight loss in Alzheimer patients despite adequate food intake, we reviewed the existing literature. To date, eight international studies have focused on nutrition in Alzheimer's disease and all have found weight loss. It is not clear whether this weight loss is a component of or a consequence of the disease.

These findings suggest systemic, metabolic alterations in Alzheimer's disease. They require further investigation as to their nature and as to their appropriate recognition and management to retard the deteriorating effects of chronic weight loss and malnutrition. Finally, some reports lead to speculation that nutritional strategies may improve cognitive function.
