Globally, falls in older people are a leading cause of injury-related mortality and morbidity. Cognitive impairment is a well-known risk factor for falls in this population group. While there is now a large body of evidence to support effective interventions for falls reduction across care settings, very little is known about interventions in the vulnerable, but increasing population of cognitively impaired community-dwelling older people. Therefore, the purpose of this systematic review is to investigate interventions designed to reduce falls in community-dwelling, cognitively impaired older adults. ⋯ The diversity of interventions, study designs, populations, and quality of the studies, which met inclusion criteria, resulted in conflicting evidence and inconclusive results for falls prevention interventions in this highly complex population.

The objectives of this study were to examine the factors modifying the relationship between cortisol level and prevalent/incident cognitive impairment in older adults and to verify whether these relationships were non-linear. ⋯ These results suggest that cognitive impairment in older adults is linked to higher or lower cortisol level depending on characteristics such as anxiety, depressive episode, education level, and physical health.
