Prevalence of Cognitive Impairment Without Dementia and Dementia in Tremembé, Brazil.

Background:The prevalence of cognitive impairment is insufficiently determined in developing countries. The aim of this study was to ascertain the prevalence of cognitive impairment without dementia and dementia in community-dwelling elderly in Brazil. Methods:This was a single-phase cross-sectional survey of the elderly (aged 60 years and above) living in the municipality of Tremembé, Brazil. Twenty percent of the households with elderly persons were randomly selected from urban and rural areas, to obtain a homogenous representation of all socioeconomic and cultural levels. Results:We assessed 630 individuals [mean age, 71.3 y (±7.99); mean years of education, 4.9 (±4.54)] and found prevalence rates of 17.5% (95% confidence interval, 14.6-20.6) for dementia and 19.5% (95% confidence interval, 16.6-22.8) for cognitive impairment without dementia. These prevalence rates were influenced by age (P<0.001) and by educational level (P<0.001). There was no significant sex difference among diagnostic groups (P=0.166). The prevalence of dementia was higher in relatively younger individuals (below 70 y) when compared with other studies. Besides, dementia was associated with low socioeconomic status, stroke, previous psychiatric disorder, alcoholism, and epilepsy. Conclusions:The prevalence of dementia in this study was higher than in other studies, particularly among younger elderly.

Prevalence of depressive symptoms among elderly in the city of Tremembé, Brazil: Preliminary findings of an epidemiological study

Depression is a heterogeneous mental disease classified as a set of disorders, which manifest with a certain duration, frequency and intensity. The prevalence of depression in the elderly ranges from 0.5 to 16%. OBJECTIVE To establish, in an epidemiological study, the prevalence of significant depressive symptoms in the population aged 60 years or older. METHODS Results of a cross-sectional epidemiological study, involving home visits, being carried out in the city of Tremembé, Brazil, were reported. The sample was randomly selected by drawing 20% of the population over 60 years from each of the citys census sectors. In this single-phase study, the assessment included clinical history, physical and neurological examination, cognitive evaluation, the Cornell scale and the Patient Health Questionnaire for psychiatric symptoms. Scores greater than or equal to 8 on the Cornell scale were taken to indicate the presence of depressive symptoms. RESULTS A total of 455 elders were assessed, and of these 169 (37.1%) had clinically significant depressive symptoms (CSDS). Depression prevalence was higher among women (p<0.001) and individuals with lower education (p=0.033). The Chi-square test for trends showed a significant relationship where lower socioeconomic status was associated with greater likelihood of depressive symptoms (p=0.005). CONCLUSION The prevalence of depressive symptoms was high in this sample of the population-based study and was associated with female gender, low educational level and socioeconomic status. The assessment of the entire population sample must be completed.

Decision-making in Cognitively Unimpaired Illiterate and Low-educated Older Women: Results on the Iowa Gambling Task

Objective This study investigated the pattern of decision-making (DM) on the Iowa Gambling Task (IGT) in a sample of Portuguese speaking healthy older women in Brazil with limited education: illiterate, 1–2 years, and 3–4 years of schooling. Methods Around 164 non-demented community-dwelling women participated in the study. Among them 60 were illiterate, 52 had 1–2 years of schooling and 52 had 3–4 years of schooling. Participants completed the instruments: Brief Cognitive Screening Battery (BCSB), Mini-Mental State Examination, Verbal Fluency Test (animal category), Clock Drawing Test, Geriatric Depression Scale, Geriatric Anxiety Inventory, Digit Span Forward and Backward, Ravens Coloured Progressive Matrices, Wisconsin Card Sorting Test, and IGT. Results The three education groups were equivalent as to age, number of diseases, medications taken daily, depression, and anxiety symptoms. In the IGT the literate older adults made more advantageous choices than the illiterate and IGT performance improved linearly with higher levels of education. IGT performance correlated significantly with all cognitive test scores with the exception of the memorization of the pictures on the BCSB. Conclusion The results suggested that education influences IGT performance, with worse scores among the illiterate. Results may be used by clinicians to interpret IGT performance among seniors with low literacy levels.

TESTS OF EXECUTIVE FUNCTION MAY NOT DIFFERENTIATE ALZHEIMER’S DISEASE FROM BEHAVIORAL VARIANT FRONTOTEMPORAL DEMENTIA

twenty-six patients with MCI, 97 patients with AD, and 91 healthy older adults were recruited. All participants consented to examination with the MMSE-2, the MMSE, and other detailed neuropsychological assessments. Discriminant analysis of each test was used to evaluate and compare their correct classifications and sensitivity and specificity of each test was compared using receiver operating characteristic (ROC) analysis. Results: The result of discriminant validity of MMSE-2 showed that 71.1% of cases correctly identified in a discriminant analysis of patients with MCI (68.6%), patients with AD (78.4%), and healthy older adults (72.5%). The result of discriminant validity of K-MMSE showed that 67.9% of cases correctly identified in a discriminant analysis of patients with MCI (83.6%), patients with AD (68.0%), and healthy older adults (28.6%). Moreover, the AUC of the MMSE2:BV (0.708), the MMSE-2:SV (0.720), and the MMSE-2:EV (0.728) were larger than the AUC of the K-MMSE (0.703) when comparing with healthy older adults and patients with MCI. However, the AUC of the K-MMSE (0.936) was lager than the MMSE2:BV (0.930), the MMSE-2:SV (0.925), and the MMSE-2:EV (0.921) when comparing with patients with MCI and AD. Conclusions:TheMMSE-2 is more useful cognitive screening instrument for assessing cognitive impairment in a Korean population than the K-MMSE. Especially, theMMSE-2:SVand theMMSE-2:EVare more sensitive to discriminate cognitive dysfunction between healthy normal aging and patients with MCI, but when comparing between patients with MCI and AD, the MMSE-2:BV and the KMMSE are more sensitive to discriminate cognitive dysfunction.

DISEASE STAGING IN FRONTOTEMPORAL DEMENTIA AND ALZHEIMER'S DISEASE: THE CONTRIBUTION OF THE FRONTOTEMPORAL DEMENTIA RATING SCALE (FTD-FRS) IN A 12-MONTH FOLLOW-UP STUDY

811⁄49.407, p1⁄40.0002, R1⁄4.188, b1⁄47.897) but not the lPRC, ERC, or PHC (all p-values <.05). Conclusions:Verbal semantic memory tests are commonly used tools in AD diagnosis. We found that the fluency performance for living, but not nonliving, things differentiated NCs from very early AD patients. Further, we showed that only mean cortical thickness of the mPRC predicted living thing fluency performance. These results are in line with the findings of Kivisaari et al. (2012) showing that only mPRC thickness significantly predicted picture naming performance for living relative to nonliving things. Fluency tasks with living thing categories may provide an early marker of incipient AD.

Performance of the Visual Analogue Scale of Happiness and of the Cornell Scale for Depression in Dementia in the Tremembé Epidemiological Study, Brazil

Depression is a major growing public health problem. Many population studies have found a significant relationship between depression and the presence of cognitive disorders. Objective To establish the correlation between the Visual Analogue Scale of Happiness and the Cornell Scale for Depression in Dementia in the population aged 60 years or over in the city of Tremembé, state of São Paulo, Brazil. Methods An epidemiological survey involving home visits was carried out in the city of Tremembé. The sample was randomly selected by drawing 20% of the population aged 60 years or older from each of the citys census sectors. In this single-phase study, the assessment included clinical history, physical and neurological examination, cognitive evaluation, and application of both the Cornell Scale and the Analogue Scale of Happiness for psychiatric symptoms. The presence of depressive symptoms was defined as scores greater than or equal to 8 points on the Cornell Scale. Results A total of 623 subjects were evaluated and of these 251 (40.3%) had clinically significant depressive symptoms on the Cornell Scale, with a significant association with female gender (p<0.001) and with lower education (p=0.012). One hundred and thirty-six participants (21.8%) chose the unhappiness faces, with a significant association with age (p<0.001), female gender (p=0.020) and low socioeconomic status (p=0.012). Although there was a statistically significant association on the correlation test, the correlation was not high (rho=0.47). Conclusion The prevalence of depressive symptoms was high in this sample and the Visual Analogue Scale of Happiness and Cornell Scale for Depression in Dementia should not be used as similar alternatives for evaluating the presence of depressive symptoms, at least in populations with low educational level.
