Abstract Background: The Cognitive Abilities Screening Instrument (CASI) is one of the most commonly used cognitive screening tools to assess overall cognitive function in people with dementia. However, the unidimensionliaty of the CASI using Rasch analysis has not been evaluated in people with dementia, limiting its utility in clinical and research settings. Unidimensionality verifies whether all items of a measure reflect a single theoretical construct, which is necessary to determine whether clinicians and researchers can appropriately use the sum scores of the CASI to describe overall cognitive function. This study aimed to examine unidimensionality of the CASI using Rasch analysis and estimate Rasch person reliability in people with dementia. Methods: CASI data of people with dementia was collected from medical records of one general hospital in northern Taiwan. A total of 506 people with dementia were recruited from the Department of Neurology. Unidimensionality was confirmed through two assumptions: (1) the infit and outfit mean square (MnSq) were 0.6-1.4, and (2) residual variance of the first principal component in principal component analysis was ≤ 20%. Rasch person reliability was estimated after undimensionality was supported. Results: One item from the list-generating fluency dimension was misfitted (outfit MnSq=1.42) and was deleted. The unidimensionality of the remaining 45 items (referred to as the CASI-45) was supported with an infit and outfit MnSq (0.85-1.24 and 0.84-1.28, respectively) and low residual variance of the first principal component (12.8%). The Rasch person reliability of the CASI-45 was 0.62. Conclusion: The CASI-45 showed a unidimensional construct and had acceptable Rasch person reliability in people with dementia.

ABSTRACTBackground: Large-scale nationwide data describing the end-of-life characteristics of older people with dementia are lacking. This paper describes the dying process and end-of-life care provided to elderly people with mild or severe dementia in Belgium. It compares with elderly people dying without dementia.Methods: A nationwide retrospective mortality study was conducted, via representative network of general practitioners (GPs) in 2008 in Belgium, with weekly registration of all deaths (aged ≥ 65) using a standardized form. GPs reported on diagnosis and severity of dementia, aspects of end-of-life care and communication, and on the last week of life in terms of symptoms that caused distress as judged by the GP, and the patients’ physical and cognitive abilities.Results: Thirty-one percent of our sample (1,108 deaths) had dementia (43% mildly, 57% severely). Of those, 26% died suddenly, 59% in care home, and 74% received palliative treatment, versus 37%, 19%, and 55% in people without dementia. GP–patient conversations were less frequent among those with (45%) than those without (73%) dementia, and 11% of both groups had a proxy decision-maker. During the last week of life, physical and psychological distress was common in both groups. Of older people with dementia, 83% were incapable of decision-making and 83% were bedridden; both significantly higher percentages than found in the group without dementia (24% and 52%).Conclusions: Several areas of end-of-life care provision could be improved. Early communication and exploration of wishes and appointment of proxy decision-makers are important components of an early palliative care approach which appears to be initiated too infrequently.

ABSTRACT Dementia prevalence is increasing in developing countries due to population aging. Brief tests for assessing cognition and activities of daily living are very useful for the diagnosis of dementia by the clinician. Low education, particularly illiteracy, is a hindrance to the diagnosis of dementia in several regions of the world. Objectives: To compare the Brazilian version of the Cognitive Abilities Screening Instrument-Short Form (CASI-S) with the Mini-Mental State Examination (MMSE) and Pfeffer Functional Activities Questionnaire (PFAQ) for the diagnosis of dementia in illiterate elderly. Methods: A cross-sectional study with illiterate elderly of both genders seen at the outpatient clinics of the Institute of Gerontology and Geriatrics Jundiaí, São Paulo state was performed. Spearman's correlation coefficient was used to correlate CASI-S, MMSE and PFAQ scores. Results: The sample comprised 29 elderly over 57 years old whose mean scores on the CASI-S (scores ranging from 3 to 23) and the MMSE (scores ranging from 2 to 23) were 11.69 and 12.83, respectively. There was a strong significant correlation between the CASI-S and MMSE (r=0.75, p<0.001) and a moderate correlation coefficient that was significant and negative between the PFAQ and CASI-S (r= -0.53 p=0.003),similar to that between the MMSE and PFAQ (r= -0.41 p=0.025). Conclusion: The Brazilian version of the CASI-S demonstrates ease of application and correction in the illiterate elderly, and warrants further studies regarding its applicability for the diagnosis of dementia in populations with a heterogeneous educational background.

The primary focus of research related to spiritual and ministry needs of older people, historically and in the present, has been on those whose cognitive abilities are only minimally impaired. The older adult with a dementia like Alzheimer’s disease, however, has not received as much attention. This may be related to a lack of any theoretical framework from which to understand what may be happening to a markedly confused person spiritually, and how a person with progressive cognitive impairment might still be able to maintain a relationship with God and be ministered to by a God who may only be remembered vaguely, if at all. Elderly persons with dementia with a faith background rooted in the Judeo-Christian worldview are often able to respond to various rituals of their faith, verbally, physically, and emotionally. Common practices like familiar prayers, Bible readings, hymns, and attendance at worship services where collective memory is shared can serve as memory joggers to reconnect the person, not only to the faith community, but to a faithful God. A spiritual care ministry to older people with dementia can be considered a ministry of memory.

ABSTRACTBackground:The Cognitive Abilities Screening Instrument – Short (CASI-S) is a brief cognitive screening test. However, there is limited information regarding its applicability in primary care.Objectives:To ascertain whether the CASI-S differentiates between dementia patients and normal controls in primary care; to examine its correlation with other cognitive instruments, to analyze its internal consistency, test-retest stability, and diagnostic accuracy.Methods:In a case-control study, carried out at two Primary Care Units (PCUs) in the eastern region of the city of São Paulo, 47 older adults were diagnosed with dementia according to DSM-IV criteria (mean age = 76.81 ± 7.03 years), and 55 were classified as normal controls (mean age = 72.78 ± 7.37 years), by a multidisciplinary panel which had access to results from a comprehensive cognitive battery and the patients’ health data. The present analyses included results from the Mini-Mental State Examination (MMSE). The CASI-S was not used to determine diagnostic status.Results:The CASI-S was easily applied in the primary care setting. There was a significant performance difference (p < 0.001) between dementia patients (15.57 ± 7.40) and normal controls (26.67 ± 3.52) on the CASI-S. CASI-S scores correlated with age (ρ = −0.410, p < 0.001), educational level (ρ = 0.373, p < 0.001), and MMSE score (ρ = 0.793, p < 0.001). The internal consistency of the CASI-S was high (α = 0.848) and the correlation between test and retest was 0.688, suggesting adequate temporal stability. In the ROC curve analyses, scores of 22/23 generated an area under the curve of 0.907, with sensitivity of 93% and specificity of 81%.Conclusions:The CASI-S can be useful for dementia screening in primary care in Brazil.
