The extent of social interaction of aggressive, cognitively impaired nursing home residents and the relationship between social interaction and selected resident characteristics were explored in this study, which was part of a larger experimental study of the effect of dementia education for staff on the aggressive behavior of cognitively impaired residents. Staff rated residents using the Social Interaction Scale (SIS),which has two subscales: Institutional Interaction and Family/Community Interaction. Mean SIS scores were low; institutional interaction scores were higher than family/community scores. Marital status, morale, degree of cognitive impairment, dependency, and sexual aggression were significantly associated with social interaction, but gender and age were not.

The objective of this study was to examine the effects of morning bright light on behavioral disturbances in dementia using a repeated measures ABA design. We hypothesized that morning bright light in demented patients reduces the agitation rating and directly observed disruptive behavior, but increases observed positive behavior.

The study was done in a special care unit of a long term care facility, with 16 demented residents ages 60 to 89, 13 female and three male. Morning bright light (Day-Light Box 10000, produced by DayLight Technologies, Inc, providing 10,000 lux) was administered Monday to Friday during the treatment week. The Global Deterioration Scale rating at baseline, followed by baseline, treatment and post-treatment ratings in the Cohen-Mansfield Agitation Inventory (CMAI) and Environment-Behavior Interaction Code (EBIC) were used as measurements

Compared to baseline, the mean total Cohen-Mansfield score decreased more during the phototherapy week than during the post-treatment week (p < 0.05 on one-tailed paired t-test). Regardless of phototherapy, Cohen-Mansfield scores decreased significantly in summer versus fall-spring (p < .005). Although the direct behavioral measures [EBIC] showed no statistically significant change compared to baseline, there was a pattern of greater mean increase in positive behaviors (p = .08) during phototherapy than in the post-treatment week, and a mean decrease of total disruptive behaviors most pronounced in the post-treatment week (p = .05).

Bright light therapy has modest efficacy in reducing agitation, with possible concurrent improvement in positive behaviors. Disruptive behaviors may also become less frequent during phototherapy with evidence of even greater delayed optimal effect. Further research should focus on subgroups of patients demonstrating a particularly robust response, enhance power through a larger sample, provide for longer light exposure, and control for seasonal variables.

Although discussion of Alzheimer's disease (AD) is increasing in the popular media, knowledge about AD has not been extensively examined. This study analyzes factors associated with knowledge about AD in an elderly sample. Data from a mail survey was sent to a random sample (N=527) of subjects aged 60 and older in the Northwest Indiana metropolitan area. We performed a multiple regression analysis to determine the effect of demographic characteristics, knowledge about services for the elderly, and health information scanning on knowledge about AD. Results indicate that misconceptions of AD are widespread among the elderly population. Race and general knowledge about services for the elderly is associated with specific misconceptions of AD. In addition, a higher education level is associated with fewer misconceptions of AD, while health information scanning is not. These findings suggest that there is a need for accurate information about both AD and community services for older people. Results of these analyses indicate the importance of addressing race and education level when disseminating information about services and AD.

While there is evidence to suggest that in long term residential care settings the provision of more choices and better designed environments have a positive effect on agitation and disturbed behaviors, there are no controlled studies on the effect of imposed confinement in these settings or in acute units.

The effect of mandatory confinement indoors on the incidence of verbal and physical aggression and psychotropic medication use among patients with dementia and associated psychiatric and behavioral disturbance was studied. The setting was an acute psychogeriatric admission unit accommodated in a colonial building originally built as a military barracks. A convenience sample was studied to assess changes in levels of aggression and nurse-initiated psychotropic medication use during and after a 32-day period of indoor confinement. Correlations with gender, diagnosis, pre-admission disturbed behavior and ultimate discharge outcome were examined.

Release from mandatory confinement indoors was correlated with decreases in both verbal and physical aggression as well as medication use. Correlations could be identified between decreases in aggression and male gender, pre-admission aggressive behavior and discharge outcome. Decreased medication use was correlated with discharge outcome. The freedom to go outdoors or have access to extra space should be an important component of the environmental design and care philosophy for the acute admission of people who experience dementia and associated psychiatric and behavioral disturbance.

Clients with dementia in an adult day care center were observed taking part in regular activities programming or Montessori-based activities developed for persons with dementia. During the nine-month study, clients in Montessori-based activities exhibited greater amounts of constructive engagement, defined as motor or verbal behavior exhibited in response to the activity in which the client was taking part, than clients in regular programming. Montessori-based activities also elicited less passive engagement, defined as listening and/or looking behavior exhibited in response to the activity the clients were participating in, than regular programming. Implications of these results and ways to implement Montessori-based programming in settings serving persons with dementia are discussed.

A series of individual caregivers were studied in a program for reducing caregiver burden. Using a modified caregiver burden inventory for assessment, an educational program and a needs-based intervention algorithm to guide intervention of caregivers, attempts were made to mitigate caregiver burden. A study of individual cases suggested that primary burden for caregivers included time spent in caring for loved ones and missing out on phase-of-life-appropriate activities. It was our impression that caregiver burden did not represent an appropriate outcome measure in this situation, and that the most desired outcome was the openness of individuals to assistance when and where they were able to accept it.
