“…The FM kernel is defined (42) The YBG kernel is defined: (43) where Ω n1 defines the orientation of the unit vector u⃑ n and the three-particle correlation function is defined: (44) The definitions in eq (42) and eq (44) assume that the average over configurations is equivalent to the appropriate ensemble average. After integrating over r⃑ 1 in eq (43), the YBG kernel may be expressed (45) The integrals over the orientational degrees of freedom may then be evaluated according to the identity in eq (36).…”

(2005)]. If no approximations are made, the MS-CG method yields a many-body multi-dimensional potential of mean force describing the interactions between CG sites. However, numerical applications of the MS-CG method typically employ a set of pair potentials to describe non-bonded interactions. The analogy between coarse-graining and the inverse problem of liquid state theory clarifies the general significance of three-particle correlations for the development of such CG pair potentials. It is demonstrated that the MS-CG methodology incorporates critical three-body correlation effects and that, for isotropic homogeneous systems evolving under a central pair potential, the MS-CG equations are a discretized representation of the well-known Yvon-Born-Green equation. Numerical calculations validate the theory and illustrate the role of these structural correlations in the MS-CG method.

“…3–5,18–24 Overall, most studies of cognitive test performance to date typically have shown little difference between Native and non-Native samples, although most of these investigations have been conducted with relatively acculturated tribes, 3–5,22,25 some of whom also have relatively low levels of genetic American Indian heritage. 21 This is important because acculturation status may affect elders’ performance on cognitive tests.…”

Little is known about factors that predict older American Indians' performance on cognitive tests. This study examined 137 American Indian elders' performance on the MMSE and the Dementia Rating Scale-Second Edition (DRS-2). Multivariate regression identified younger age, more education, not receiving Supplemental Security Income, and frequent receipt of needed health care as predictors of better performance on the MMSE. Better performance on the DRS-2 was predicted by more education, boarding school attendance, not receiving Supplemental Security Income, and frequent receipt of needed health care. This study points to the importance of economic and educational factors on cognitive test performance among American Indian elders.Despite a dramatic increase in American Indian life expectancy in recent years, 1 remarkably little is known about the nature and frequency of cognitive impairment among older American Indians. 2 Although a few studies have examined the utility of standard neuropsychological testing in this population, [3][4][5] little is known about the performance on common neurocognitive screening measures among American Indian elders. This gap is especially noteworthy since American Indians have high rates of several conditions that increase risk for poor cognitive functioning, such as alcohol abuse and addiction, 6-8 diabetes, 9,10 traumatic brain injury, 11,12 and overweight/obesity and cardiovascular disease. 13,14 Further, American Indians are disproportionately poor (28.4% compared with 12.4% of the U.S. general population), 15 and low socioeconomic status has been linked to several factors that might affect cognitive ability. These include pre-and postnatal Address correspondence to Lori L. Jervis, 2 Partners Place, 3100 Monitor Ave., Room 100, Norman, OK 73072-7805; lori.jervis@ou.edu. This constellation of factors suggests that American Indians may be at considerable risk for the development of cognitive disorders associated with aging. As the population of older American Indians continues to increase, so does the need to develop methods by which to identify cognitive impairment and its optimal assessment in this population. HHS Public Access American Indians, Dementia Prevalence, and Cognitive TestingA handful of small, non-population-based, empirical studies have examined dementia among American Indian and Canadian First Nations people. [3][4][5][18][19][20][21][22][23][24] Overall, most studies of cognitive test performance to date typically have shown little difference between Native and non-Native samples, although most of these investigations have been conducted with relatively acculturated tribes, [3][4][5]22,25 With this in mind, our work examines performance on the MMSE and the DRS-2 in a community-dwelling American Indian sample. The goal was to investigate the predictors of differential performance on these assessment instruments in this culturally unique population, since it is likely that performance reflects factors other than neurocognitive disease alone. It was hypothes...

“…Although the body of knowledge is not very large and there is a low grade of diversity of the participants [ 10 ], there are some studies addressing experiences of dementia in other countries and among ethnic groups and immigrant populations in western societies. These studies have revealed different cultural constructions of dementia, from a normative understanding in India [ 11 ] to a ‘supernormal’ construct of the disease in native Americans where dementia-related symptoms are perceived as normal while the person is perceived as being in touch with a supernatural world [ 12 ].…”

Experiences of dementia in a foreign country: qualitative content analysis of interviews with people with dementia

et al. 2014

BackgroundDementia is a worldwide health concern of epidemic proportions. Research in the field of subjective experience of dementia suffers from a lack of diversity of their participants including immigrants. Different portraits of life with dementia could help us understand how people with dementia conceptualise their experiences of dementia and how they live. Our study aimed to explore the subjective experiences of living with dementia among Iranian immigrants in Sweden.MethodsQualitative content analysis of interviews with fifteen people with dementia from Iranian immigrant backgrounds were conducted (8 females and 7 males).ResultsThree themes and seven associated sub-themes were revealed. The themes included: Being a person with dementia means living with forgetfulness (personal sphere), living with forgetfulness in the private sphere means feeling incompetent but still loved, living with forgetfulness in the public sphere means feeling confident and secure but also isolated.ConclusionsLiving with dementia for the participants meant living with forgetfulness. They experienced feeling incompetent but still loved within their families and feeling confident and secure but also isolated in the society. Educating people with dementia and their families about the course and process of dementia may help them understand the changes better and adjust their expectations. Our study can provide a basis for healthcare workers to understand the experiences of living with dementia from this specific perspective.
