- Prevalence of Cognitive Impairment Without Dementia and Dementia in Tremembe, Brazil(2016) CESAR, Karolina G.; BRUCKI, Sonia M. D.; TAKADA, Leonel T.; NASCIMENTO, Luiz F. C.; GOMES, Camila M. S.; ALMEIDA, Milena C. S.; OLIVEIRA, Maira O.; PORTO, Fabio H. G.; SENAHA, Mirna L. H.; BAHIA, Valeria S.; SILVA, Thais B. L.; IANOF, Jessica N.; SPINDOLA, Livia; SCHMIDT, Magali T.; JORGE, Mario S.; VALE, Patricia H. F.; CECCHINI, Mario A.; CASSIMIRO, Luciana; SOARES, Roger T.; GONCALVES, Marcia R.; MARTINS, Ana C. S.; DARE, Patricia; SMID, Jerusa; PORTO, Claudia S.; CARTHERY-GOULART, Maria T.; YASSUDA, Monica S.; MANSUR, Leticia L.; NITRINI, RicardoBackground: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 Tremembe, 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.
- Validity and Reliability of the Frontotemporal Dementia Rating Scale (FTD-FRS) for the Progression and Staging of Dementia in Brazilian Patients(2018) LIMA-SILVA, Thais B.; BAHIA, Valeria S.; CECCHINI, Mario A.; CASSIMIRO, Luciana; GUIMARAES, Henrique C.; GAMBOGI, Leandro B.; CARAMELLI, Paulo; BALTHAZAR, Marcio; DAMASCENO, Benito; BRUCKI, Sonia M. D.; SOUZA, Leonardo C. de; NITRINI, Ricardo; MIOSHI, Eneida; YASSUDA, Monica S.Introduction:Few studies on instruments for staging frontotemporal dementia (FTD) have been conducted.Objective:The objective of this study was to analyze the factor structure, internal consistency, reliability, and convergent validity of the Brazilian version of the Frontotemporal Dementia Rating Scale (FTD-FRS).Methods:A total of 97 individuals aged 40 years and above with >2 years' education took part in the study, 31 patients diagnosed with behavioral variant FTD (bvFTD), 8 patients with primary progressive aphasia, 28 with Alzheimer disease, 8 with mild cognitive impairment, and a control group of 22 healthy subjects. The FTD-FRS was completed by family members or caregivers, and Neurologists completed the 8-item Clinical Dementia Rating for Frontotemporal Lobar Degeneration (CDR-FTLD) scale (6 original domains plus Language and Behavior). The Alzheimer disease and FTD patients had equivalent disease severity level.Results:The internal consistency of the FTD-FRS, estimated by Cronbach , was 0.975 whereas test-retest reliability was 0.977. Scree plot and exploratory factor (Varimax rotation) analyses revealed the existence of 4 factors, with eigenvalues >1, which together explained 77.13% of the total variance with values of 1.28 to 17.52. The domains of the Brazilian version of the FTD-FRS scale correlated with the domains of the CDR-FTLD.Conclusions:The present study is the first to document the factorial structure of the FTD-FRS and its convergent validity with the CDR-FTLD. These tools are key to determine dementia severity in FTD. The Brazilian FTD-FRS demonstrated adequate psychometric properties for use in Brazil. This instrument may contribute to disease staging in FTD and may help to document intervention-related changes.
