The occurrence of different intrusive errors in patients with Alzheimer's disease, multiple cerebral infarctions, and major depression

Recent evidence suggests that specific types of intrusive errors may occur more often in the protocols of Alzheimers disease (AD) patients than in those of patients diagnosed with other types of dementia. Using the FULD Object Memory Evaluation, we documented the occurrence of five qualitatively different types of intrusive errors for mildly and moderately impaired patients with AD and multiple cerebral infarctions (MCI). Depressed and normal elderly controls were also studied. Despite an equivalent degree of impairment on a broad array of neuropsychological measures, mildly impaired AD patients evidenced greater deficits on a measure tapping retrieval from semantic memory and demonstrated a higher occurrence of specific types of intrusive errors relative to their mildly impaired MCI counterparts. Further, both of these measures were highly correlated, suggesting that these indices may be particularly sensitive to semantic dysfunction associated with early AD.

Caregiving for Hispanic Alzheimer's Disease Patients: Understanding the Problem

The authors analyze aspects of caregiving for Hispanic Alzheimers disease (AD) patients. A review of the literature on caregiving and ethnicity and data concerning caregiving for AD patients in different Hispanic groups are presented. The presence of ethnicity-related differences in caregiving for Hispanic AD patients is confirmed. These differences, however, appear to be present largely in certain areas, such as household composition, distribution of caregiving roles, help-seeking behavior, and site of caregiving. The authors consider areas that need to be addressed in future research and specific modifications to current caregiving models for the study of AD patients in the Hispanic community.

Establishment of a Predominantly African-American Cohort for the Study of Alzheimer's Disease : The South Carolina Alzheimer's Disease Clinical Core

Background/Aims: The recruitment of culturally diverse subject populations into research studies, particularly African-Americans (AA), has been the focus of intense interest by many groups. Methods: In this paper, we present the methodology utilized to create a predominantly AA cohort for the longitudinal study of risk factors in Alzheimer’s disease (AD). The underlying strategy was that of identifying geographically diverse clinical venues within South Carolina (SC) where large numbers of AA patients already come to seek medical care. Results: This strategy was successful, although recruitment rates for AA subjects (43.4%) still fell below those for white subjects (70.3%; p = 0.0025). Subject characteristics of AA subjects that chose to enroll were not substantially different from those that declined to participate. The demographic characteristics of this cohort were largely similar to those of the SC Alzheimer Disease Registry, a population-based database. The problems of standardization of subject recruitment and assessment across diverse clinical venues are also addressed. Conclusion: The utilization of geographically diverse sites for research recruitment where minorities already receive medical care is one practical solution to the problem of minority participation in research. Multi-site recruitment to improve minority recruitment can be accomplished with acceptable standardization and inter-rater reliability.
