Informant Questionnaire on Cognitive Decline in the Elderly--Farsi Version

Abstract. This study examines the psychometric properties of the IQCODE and its applicability in the Iranian elderly population. A group of 95 elderly patients with at least 4 years of formal education who fulfilled the criteria of DSM-IV-TR for dementia were examined by the MMSE and the AMTs. The Farsi version of the IQCODE was subsequently administered to their primary caregivers. Results showed a significant correlation ( p = .01) between the score of the questionnaire and the results of the MMSE ( r = −0.647) and AMTs ( r = −0.641). A high internal reliability of the questionnaire was confirmed by Cronbach’s alpha coefficient (α = 0.927) and test-retest reliability by correlation coefficient ( r = 0.81). This study found that the IQCODE has acceptable psychometric properties and can be used for evaluating the cognitive state in the elderly population of Iran.

Abstract Background Few previous cohorts have studied the different type of physical activities and the degree of cognitive decline. The objective of this work was to analyze the leisure, domestic and professional activities with mild and moderate cognitive disorders in older people living in community. Methods The study used data from the longitudinal and observational study, FrèLE (FRagility: Longitudinal Study of Expressions). The collected data included: socio-demographic variables, lifestyle, and health status (frailty, comorbidities, cognitive status, depression). Cognitive decline was assessed by using: MMSE (Mini-Mental State Examination) and MoCA (Montreal Cognitive Assessment). MoCA was used with two cut-offs (26 and 17) so as to define mild and moderate cognitive disorders Physical activity was assessed by the PASE (Physical Activity Scale for the Elderly), structured in three sections: leisure, domestic and professional activities. Spline and proportional hazards regression models (Cox) were used to estimate the risk of cognitive disorders. Results At baseline, 1623 participants were included and the prevalence of cognitive disorders was 6.9% (MMSE) and 7.2% (MoCA), mild cognitive disorders was 71.3%. The mean age was 77 years, and 52% of the participants were women. After a 2 years long follow-up, we found 6.9% (MMSE) and 6% (MoCA) cognitive disorders on participants. Analyses showed that domestic activities were associated to cognitive decline (HR = 0.52 [0.28-0.94] for MMSE and HR = 0.48 [0.28-0.80] for MoCA). No association were found with leisure and professional activities, and no spline were significant with mild cognitive disorders. Conclusions Analysis showed a relationship between cognitive disorders and type of physical activity, thanks to the use of specific questionnaire of elderly and two global test of cognition. These findings will contribute to the debate on the beneficial effects of physical activity on cognition. Key messages This work allowed to compare two test of cognition and their link with physical activity. It contributes to the debate on the beneficial effects of physical activity on cognition. The work allowed us to see the effect of the different types of physical activity and the impact of the statistical method on the results.

Functional Gain

The objective of this paper was to study the evolution of cognitive status and of functional dependency in patients over 65 and how these relate to different demographic variables. The sample consisted of 259 elderly people admitted to the Hospital Neurotraumatológico in Jaen (Spain) with a diagnosis of bone fracture. Sociodemographic data was obtained through a semi-structured interview. Furthermore, the following tests were also administered: Barthel Index, Lawton and Brody’s Scale, Phototest, and Informant Questionnaire on Cognitive Decline in the Elderly. According to the results of this study, elderly patients show increased dependency during hospitalization and a mild recovery at discharge, but without regaining their dependency values prior to hospitalization. There is a differential incidence of functional decline as a function of gender, where women have significantly lower functional dependency at home than men and they do not decline as much as men do from their status prior to hospitalization. Also, we have encountered significant inverse relations between the different levels of dependency and cognitive status, and the age of the elderly patient. Moreover, married patients experienced greater functional gain than did the widowed patients, regardless of gender.

Depressive States

Background. We report the outcome of depressive states after 3-4 years in a community sample of the elderly.Methods. A sample of 1045 persons aged 70+ years in 1990–1 was re-interviewed after 3·6 years.Results. Mortality (21·7%) and refusal or non-availability (10·4%) were higher in those who initially had had a diagnosis or symptoms of depression. Of those with an ICD-10 depressive episode in 1990–1, 13% retained that diagnosis. Of those who were not depressed initially only 2·5% had become cases. Depression was unrelated to age or apolipoprotein E genotype. The best predictors of the number of depressive symptoms at follow-up was the number at Wave 1, followed by deterioration in health and in activities of daily living, high neuroticism, poor current health, poor social support, low current activity levels and high service use. Depressive symptoms at Wave 1 did not predict subsequent cognitive decline or dementia.Conclusions. Non-random sample attrition is unavoidable. ICD-10 criteria yield more cases than other systems, while continuous measures of symptoms confer analytical advantages. Risk factors for depressive states in the elderly have been further identified. The prognosis for these states is favourable. At the community level, depressive symptoms do not seem to predict cognitive decline, as they do in referred series.

Rate Of Progression

The spectrum of cognitive decline in the elderly ranges from what can be classified as normal cognitive decline with aging to subjective cognitive impairment to mild cognitive impairment (MCI) to dementia. This article reviewed the up-to-date evidence of MCI including the diagnostic criteria of MCI due to Alzheimer’s disease, vascular cognitive impairment and MCI due to Parkinson disease, management and preventive intervention of MCI. There are various etiologies of MCI, and a large number of studies have been conducted to ascertain the practical modalities of preserving cognition in predementia stages. Lifestyle modification, such as aerobic exercise, is an approved modality to preserve cognitive ability and decrease the rate of progression to dementia, as well as being recommended for frailty prevention.

O presente trabalho tem como objetivo apresentar os resultados do processo de tradução e adaptação transcultural do Informant Questionnaire on Cognitive Decline in the Elderly (IQCODE) e da confiabilidade teste-reteste de uma versão para uso no Brasil. Um comitê para revisão do instrumento analisou a equivalência conceitual e de itens. Para análise de equivalência semântica, foram realizadas três traduções e três retrotraduções; elaboração de uma versão síntese; pré-teste e elaboração de uma versão teste. A consistência interna e a confiabilidade teste-reteste foram mensuradas pelo coeficiente ± de Cronbach e o coeficiente de correlação intraclasse (CCI), respectivamente. Dos 169 informantes avaliados, 97 foram retestados. O ± de Cronbach foi 0,94 e o CCI foi de 0,92. Os níveis de confiabilidade obtidos permitem concluir que a versão do IQCODE-BR se mostrou de fácil compreensão, sendo observada uma boa equivalência com a versão original.
