[Behavioral and psychological symptoms in dementia: description and management]. / Les symptômes psychologiques et comportementaux de la démence: description et prise en charge.

Behavioral and Psychological Symptoms in Dementia (BPSD) are, beside cognitive disorders, major features of Alzheimer's disease and related disorders. Diagnosis is important to enhance our knowledge of the pathophysiology of dementia and of their functional consequences for patients and caregivers. Pharmacological and non-pharmacological management of dementia depends to a large extent on the presence of BPSD. A committee of geriatricians, neurologists and psychiatrists specialized in dementia (THEMA 2) has promoted an epidemiological, diagnostic and therapeutic update in this field. This work was based on the BPSD Consensus Conference Report edited in 2000 by the International Psychogeriatric Association. This report was updated with the most recent literature reports, and was adapted to the French environment. This paper is a synthesis of this meeting, validated and corrected by the entire Thema 2 group.

A prospective study of changes on nutritional patterns 6 months before and 18 months after retirement.

To present results from a two year prospective study on diet, 6 months before and 18 months after retirement. The studied population exhibited an increase in social and physical activities over time after retirement. A significant decrease in weight was found in men 18 months after retirement. Retired individuals reported taking more time for breakfast. 45.5% of retired individuals, compared to 25.5% before retirement, took more than 30 minutes for lunch than before retirement. The amount of dietary nutrients consumed remained the same before and after retirement. However, retired individuals ate out more often, and had guests more frequently. Nutrients' distribution is similar before and after retirement. Given a life expectancy of more than 20 years after retirement, it is necessary to initiate nutritional intervention.

Nutrition and successful aging: a study of 520 elderly persons from the Toulouse and New-Mexico Aging Process Study.

Epidemiological studies of aging are usually confronted with the presence of numerous pathologies or environmental factors which make it difficult to identify the effects of aging individually. One way of reducing the variability among individuals is to use well defined criteria to select the study population. This is the choice that was made for the New Mexico and Toulouse Aging Process Studies, which were particularly turned towards successful aging. In this study we have sought to explain the diversity of states of health of the subjects of these two studies by means of an aging classification exploring the medical history, balance and walking, and the cognitive functions. This reveals that the poorer health of certain subjects (about 10% and 30% of the populations of Toulouse and Albuquerque respectively) is slightly associated with changes in eating behaviour relative to subjects who age successfully. We have, however observed a decrease in vitamin E intake in Toulouse associated with a reduction of lipids in the food. But the poorer state of health is predominantly explained by advancing age and the occurrence of pathological states. This study confirms that aging was generally successful in the two populations studied.
