Ganstigmine (CHF2819) is an acetylcholinesterase inhibitor that increases acetylcholine in rat hippocampus and ameliorates scopolamine-induced amnesia. In this article, we examined whether and how ganstigmine might prevent or rescue the neurodegenerative phenotype in AD11 antinerve growth factor (anti-NGF) mice, a transgenic model for Alzheimer's disease. The effects of ganstigmine were compared with those obtained after administration of donepezil. Results demonstrate that intraperitoneal and oral administration of ganstigmine and donepezil can reverse the cholinergic and behavioral deficit in AD11 mice but not the amyloid and phosphotau accumulation, uncovering different mechanisms leading to neurodegeneration in AD11 mice.

Subjects enrolled in the Autopsy Program at the University of Southern California Alzheimer's Disease Research Center may receive clinical diagnoses from primary care providers in the community or from specialists in neurology. We reviewed the autopsy concordance rates for 463 subjects for diagnoses made by both groups of clinicians. Seventy-seven percent of the sample met neuropathological criteria for Alzheimer's disease (AD). The overall diagnostic accuracy for this sample was 81 percent. Neurologists assessed 200 of the subjects (43 percent). The diagnostic accuracy for any clinical diagnosis among the non-neurologists was 84 percent, and 78 percent (p = 0.07) among neurologists. For AD, non-neurologists had a diagnostic concordance rate of 91 percent and neurologists 87 percent. Where neuropathological AD was missed, non-neurologists had failed to detect any cognitive impairment; neurologists had diagnosed Parkinson's disease (PD) and amyotrophic lateral sclerosis (ALS). Erroneous clinical diagnoses of AD missed dementia with Lewy bodies (DLB) or AD concurrent with Parkinson's disease (PD). Our findings identify specific foci for improving clinical diagnosis of dementia among all physicians managing dementia.

People with dementia living in the community interact with a range of people who provide services to the public. Within these interactions, there may be communication problems associated with symptoms of the person's dementia. Problems include memory loss, difficulty communicating clearly, inability to grasp complex ideas, and problems handling money. This article describes a project that set out to promote training in dementia awareness for public contact staff with the expectation that it would help them better cater to people living with dementia. We worked with a police service, members of a city council, and staff of community pharmacies. This report provides suggestions about appropriate learning outcomes and program content and recommends steps to help others set up similar education programs.

This study examined the effects of particular design interventions in a long-term care facility on residents with dementia and staff perceptions of care delivery. Major renovations were carried out in a care facility in the Midwestern United States. Renovations included a new addition of a dementia care unit designed as a cluster of resident rooms around living and dining areas, and two renovated wings with decentralized dining areas. The research methods used in the study included environmental assessment with the Professional Environmental Assessment Protocol (PEAP), behavioral mapping, and focus-group interviews with staff members. The renovated environment scored higher in PEAP and was perceived by the staff members as a more homelike setting. Although behavioral observations indicate that there was more involvement in programmed activities by the residents, the decentralized neighborhood design did not meet all the behavioral expectations due to a lack of appropriate activities, high staff turnover, and family members' resistance to the relocation of their loved ones. Organizational commitment, advanced planning for appropriate staffing levels, and dementia-related training is crucial for fuller realization of the potential of a household design.

This case study describes a person with mild-to-moderate stage Alzheimer's disease (AD) and examines the relationship between malignant positioning and the ability of a person with AD to gain the cooperation of healthy persons to construct a valued social identity. Findings reveal that malignant positioning limited the person with AD to the embarrassing social identity of dysfunctional patient; whereas, the absence of such positioning allowed the subject to gain the cooperation from others necessary to construct a valued social identity, as well as reduce embarrassment and experience greater sense of self-worth. Preliminary recommendations on reducing malignant positioning are provided. Further research is required to elucidate the degree to which the present findings may be generalized.

One of the shortcomings of the pathways-to-care literature is the lack of empirical support for the validity of the data collection methods. This study uses three common formats to collect retrospective pathways-to-care data for adults who have been diagnosed with possible or probable Alzheimer's disease (AD) and compares indicators to evaluate their relative validity. Forty family caregivers of adults diagnosed with possible or probable AD were recruited from the caregiver registry of the Boston University Alzheimer's Disease Core Center (BU ADCC). In each of three formats (questionnaire, structured interview, and medical record review), data were collected regarding four key events in the pathway to dementia care: first appearance of symptoms, first verbalized recognition of symptoms, first effort to seek professional help, and first diagnosis by a professional. In addition to the dates of these events, researchers attempted to determine: the first verbalized concern about the symptoms, who first sought professional help, what professional was first approached, and what professional made the first diagnosis. In a consensus meeting, data collected in all three formats were reviewed, and a consensus on the most likely answers to all questions was recorded and compared to data collected in each format. The results suggest that the three formats are not equivalent in terms of concurrent validity. While substantial agreement is found among data collection methods, the validity of the structured interview format and the medical record review is most consistently supported by the data in this study. Questionnaire data resulted in underestimates of delays and correlated poorly with other data sources, including the consensus judgment.
