“…We observed a statistically significant relation between memory perception and complaint about the issue. According to a study by Jacinto et al (23) , complaints regarding memory difficulties were present in 59.27% of older people, confirming the study by Mattos et al (16) who showed that 53.5% of their research participants presented subjective memory complaints. Older people who present mnemonic impairment, even if not pathological, tend to complain about memory with higher frequency (11) .…”

“…The complaint of the aged population in the mnemonic performance of activities of daily living is an aspect of investigative relevance, given that the subjective complaint can predict the evolution of dementia processes (23,27) . In addition, regardless of the increase or not in cognitive impairment, it is essential to investigate the factors that may be related to the perception of memory malfunction, since the complaint already indicates dissatisfaction and may harm their well-being and quality of life (27) .…”

RESUMO Objetivo Verificar a queixa subjetiva de memória relacionada com a fluência verbal em idosos participantes de grupos de convivência. Método Trata-se de um estudo epidemiológico, quantitativo, realizado em grupos de convivência de idosos do município de Florianópolis, Estado de Santa Catarina. Os dados foram coletados por meio de entrevista estruturada utilizando-se o Questionário de Queixas de Memória (MAC-Q) e o Teste de Fluência Verbal (TFV) por categorias semânticas animais/minuto. Para a análise descritiva inferencial, consideraram-se os dados com p < 5%. Resultados Foi encontrada a queixa de memória autodeclarada em 35,7% da amostra. Não houve associação e correlação do TFV com a percepção da memória obtida pelo MAC-Q bem como com o seu escore. A análise do TFV com os indivíduos que referiram percepção negativa de memória apresentou significância estatística. Salienta-se que foi encontrada associação significativa entre a percepção (escore do MAC-Q) e a presença da queixa de memória (referida pelos idosos em questão acrescida ao questionário). Conclusão Não houve relação entre a queixa subjetiva de memória e a fluência verbal de idosos ativos, sendo as queixas mnemônicas correlacionadas à percepção negativa da memória e ao tempo de queixa apresentada. Porém a queixa subjetiva da memória se mostrou um indicativo para aqueles indivíduos com percepção negativa da memória, sendo um aspecto que deve ser considerado na fala dos idosos ao se investigar um possível declínio cognitivo. Tais dados podem auxiliar no direcionamento das ações de políticas públicas de assistência às pessoas idosas no município, salientando-se a importância em se verificar a queixa subjetiva de memória dos idosos.

Subjective cognitive decline (SCD) may reflect a dementia prodrome or modifiable risk factor such as sleep disturbance. What is the association between sleep and SCD? Cross-sectional design, from two studies of older adults: the WHICAP in the USA, and the HELIAD in Greece. 1576 WHICAP and 1456 HELIAD participants, without mild cognitive impairment, dementia, or severe depression/anxiety were included. Participants were mostly women, with 12 (WHICAP) and 8 (HELIAD) mean years of education. Sleep problems were estimated using the Sleep Scale from the Medical Outcomes Study. SCD was assessed using a structured complaint questionnaire that queries for subjective memory and other cognitive symptoms. Multinomial or logistic regression models were used to examine whether sleep problems were associated with complaints about general cognition, memory, naming, orientation, and calculations. Age, sex, education, sleep medication, use of medications affecting cognition, comorbidities, depression and anxiety were used as covariates. Objective cognition was also used estimated by summarizing neuropsychological performance into composite z-scores. Sleep problems were associated with two or more complaints; WHICAP:β=1.93(95%CI: 1.59–2.34),p≤0.0001, HELIAD:β=1.48(95%CI:1.20–1.83),(p≤0.0001). Sleep problems were associated with complaints in all the cognitive sub-categories except orientation for the WHICAP. The associations were noted regardless of objective cognition. At any given level of objective cognition, sleep disturbance is accompanied by subjective cognitive impairment. The replicability in two ethnically, genetically, and culturally different cohorts adds validity to our results. Results have implications for the correlates, and potential etiology of SCD, which should be considered in the assessment and treatment of older adults with cognitive complaints.

“…Existing studies suggest SCC are associated with grey matter atrophy[10], white matter tract degeneration[11], amyloid burden[12], as well as cognitive function[13, 14]. Thus, SCC may provide a complementary outcome in cognitive aging research.…”

INTRODUCTION We examined the association between endogenous sex hormones and both objective and subjective measures of cognitive function. METHODS We followed 3,044 women up to 23 years in a prospective cohort study. We measured plasma levels of estrone, estrone sulfate, estradiol, androstenedione, testosterone, dehydroepiandrosterone (DHEA), and dehydroepiandrosterone sulfate (DHEA-S) in 1989–1990, conducted neuropsychologic testing in 1999–2008, and inquired about subjective cognition in 2012. RESULTS Overall, we observed little relation between plasma levels of hormones and either neuropsychologic test performance or subjective cognition. However, after adjustment for age and education, we observed a borderline significant association of higher levels of plasma estrone with higher scores for both overall cognition (p trend=0.10) and verbal memory (p trend=0.08). CONCLUSION There were no clear associations of endogenous hormone levels at mid-life and cognition in later life, although a suggested finding of higher levels of plasma estrone associated with better cognitive function merits further research.
