A specific instrument has been developed to diagnose personality disorders in older adults. However, further research is necessary to improve the diagnostic accuracy of the Gerontological Personality disorders Scale (GPS).

As suggested by the results, it can be concluded that high-quality caring relationships contribute to the need fulfillment of residents and their well-being. The quality of caring relationships is thus an important topic for further research. The field may especially benefit from longitudinal studies and studies that use observations of the caring relationship in addition to self-reports.

Electrographic signs of improved cerebral function and improved cognitive function were found after Cbl supplementation in older subjects with low plasma Cbl concentrations who were free of significant cognitive impairment. These improvements were related to a reduction of plasma tHcy concentration.

Quality of life and wellbeing in nursing homes are becoming more important in research and practice. One of the main influences on residents' wellbeing is the interaction with their professional care-givers. The purpose of this study was to explore to what extent care-givers support the residents' needs of relatedness, autonomy and competence, and how this need support is related to wellbeing. Residents and their professional care-givers of four nursing homes in the Netherlands participated in an observational and questionnaire study. Three video-observations of each resident (with different care-givers) were made during morning care. Additional data were collected by means of questionnaires. The results show that the needs of residents were, on average, moderately fulfilled during care interactions. More need support by care-givers was related to higher resident wellbeing. Care-givers provided more need support to residents with stronger functional impairments. More need support was provided by highereducated care-givers and care-givers in higher job functions. The results show the importance of need support for situational wellbeing, but the contribution to the general subjective wellbeing of residents remains unclear. Further (longitudinal) research is needed to investigate changes in wellbeing over time. Possible differences between subjective ratings and observations of need support and wellbeing should be taken into account.

Little is known about the course of personality disorders across the life span. A major problem is that the current DSM nosology for personality disorders does not account for age-associated changes in behaviour and interpersonal functioning. This editorial will discuss the main diagnostic bottlenecks when applying the current DSM-IV-TR Axis II criteria to older adults. Subsequently, suggestions will be given for future research and the development of a geriatric sub-classification.

The clinical picture of dementia portrayed in fictional movies is mild and may be misleading.
