Queixa subjetiva de comprometimento da memória em idosos saudáveis: influência de sintomas depressivos, percepção de estresse e autoestima

Intervening factors in the perception of memory decline and life purpose in older adults

Objective: To investigate the relationship between the perception of memory decline and the purpose of life in the elderly.Methods: A cross-sectional study that evaluated 235 older adults living in the city of Maringá, Paraná. A sociodemographic questionnaire, the Life Purpose Scale and the Subjective Cognitive Decline Initiative (SCD-I) were used. Data analysis was conducted using the Kolmogorov-Smirnov, Mann–Whitney “U”, Kruskal-Wallis, and Pearson's Chi-square tests (p < 0.05). Results: The results showed a higher prevalence of women with a perception of memory decline (p = 0.011) and that the elderly with more than three minimum wages had higher scores on the life purpose scale than the elderly with lower income. It was found that the elderly who does not consider that the deterioration of memory affects activities of daily living (ADL) had a greater purpose in life than the elderly who considers that the deterioration of memory impairs their ADL (p = 0.004). Conclusion: female gender seems to be a factor associated with memory decline, while higher monthly income seems to be an intervening factor in the greater purpose of life of the elderly. Not considering that memory loss harms ADLs, it seems to intervene in the best purpose of life.

Influencing Factors of Subjective Cognitive Impairment in Middle-Aged and Older Adults

The purpose of this study was to identify the factors affecting subjective cognitive impairment. We analyzed data from the 2019 Korea Community Health Survey and enrolled 68,546 middle-aged adults, aged 50 to 64 years, and 74,547 older adults, aged 65 years and older, in this study. Multiple logistic regression analysis was performed to identify factors influencing subjective cognitive impairment. Of the participants, 11,926 (17.4%) middle-aged and 21,880 (29.4%) older adults living in the community reported subjective cognitive impairment. Major factors that influenced subjective cognitive impairment in both middle-aged and older adults were gender, subjective stress, depressive symptoms, and alcohol drinking. In contrast to middle-aged adults, the marital status of older adults affected subjective cognitive impairment. Therefore, the factors affecting subjective cognitive impairment in middle-aged and older adults need to be considered for screening and management to prevent cognitive impairment and dementia. In particular, it is necessary to evaluate and manage stress and depressive symptoms from middle age to prevent subjective cognitive impairment.

Memory complaints, clinical aspects, and self-esteem in adult people with epilepsy

Memory complaints are common in adult people with epilepsy (PWEs). However, the associated clinical aspects are not yet fully understood.

Objective

This study aims to relate the occurrence of memory complaints in PWEs with clinical aspects and self-esteem.

Methods

To relate the data obtained from the Memory Complaint Questionnaire (MAC-Q) with clinical aspects, 71 PWEs were assessed using the Rosenberg Self-Esteem Scale (SES), the Mini Mental State Examination (MMSE), and the Brief Cognitive Battery-Edu. These data were compared with 55 individuals in a control group (CG).

Results

Memory complaints (MAC-Q≥25) were significantly higher in PWEs, when compared with individuals in the CG [35 (49.3%) vs. 15 (27.2%); Student's t-test; p=0.012]. Objective cognitive performance was lower in PWEs. Memory complaints were associated with a lower educational level, the presence of depression, SES, MMSE, incidental memory, and the clock-drawing test scores in PWEs.

Conclusions

Memory complaints were more frequent in PWEs than in individuals in the CG, and there was a relationship with cognitive deficit, educational level, depression, and low self-esteem.

The Relationship Between Perceived Stress and Subjective Cognitive Decline During the COVID-19 Epidemic

During the outbreak of the COVID-19 epidemic, fear of disease and its consequences, recommended lifestyle changes, and severe restrictions set by governments acted as stressors and affected people's mood, emotions, mental health, and wellbeing. Many studies conducted during this crisis focused on affective and physiological responses to stress, but few studies examined how the crisis affected cognition. The present cross-sectional study examined the relationship between physiological, affective, and cognitive responses to the epidemic. In an online survey conducted at the height of the first wave of the epidemic in Slovenia (April 15-25, 2020), 830 Slovenian residents aged 18-85 years reported the effects of stressors (confinement, problems at home, problems at work, lack of necessities, and increased workload), experienced emotions, generalized anxiety, perceived stress, changes in health, fatigue and sleep quality, and perceived changes in cognition during the epidemic. Risk factors for stress (neuroticism, vulnerability, general health, gender, and age) were also recorded. We hypothesized that stressors and stress risk factors will be related to subjective cognitive decline, with negative emotions, generalized anxiety, perceived stress, and physical symptoms acting as mediator variables. On average, the results showed a mild subjective cognitive decline during the epidemic. In structural equation modeling, 34% of its variance was predicted by the mediator variables, with negative emotions and physical symptoms having the largest contribution. Stress risk factors were predictably related to the four mediator variables. Among the stressors, confinement showed the strongest effect on the four mediator variables, implying the importance of thoughtful communication about necessary restrictive measures during emergency circumstances. The results of this study indicate that the possibility of altered cognitive function should be considered when planning work and study activities during the epidemic.

Evaluating subjective cognitive decline: a systematic review of tools available for evaluating cognitive complaints in Portuguese

BACKGROUND

Subjective cognitive decline (SCD) is a perception that is not objectively measured in screening tests. Although many tools are available for evaluating SCD, no single gold standard is available for classifying individuals as presenting SCD, in the Portuguese-speaking population. The aim of this study was to systematically review the literature for tools used to evaluate SCD in the Portuguese-speaking population.

METHODS

Four databases (Web of Science, SciELO, LILACS and MEDLINE) were primarily utilized in this study (Phase 1). Subsequently, we conducted a manual search of the literature (Phase 2). We then retrieved tools for critical evaluation (Phase 3). Studies that matched the inclusion criteria were analyzed. We summarized the features of each tool in terms of the number of questions, scoring system, benefits and deficiencies, translation and validity.

RESULTS

A total of 30 studies utilizing four questionnaires and seven different single questions were found. The tools retrieved were the Memory Assessment Questionnaire (MAC-Q; 12/30 studies), single-question methods (7/30 studies), Subjective Memory Complaint Scale (SMC scale; 5/30 studies), Prospective and Retrospective Memory Questionnaire (PRMQ; 3/30 studies) and Memory Complaint Scale (MCS; 3/30 studies). Only two were formally translated and validated for the Portuguese speaking population (PRMQ and MCS).

CONCLUSIONS

In summary, SCD is still underinvestigated in Portuguese-speaking countries. The MAC-Q was the most commonly used tool in Portuguese, despite its lack of formal translation and validation for the Portuguese-speaking population. Further studies are required in order to develop and validate a screening tool that includes questions for detecting SCD-plus features and affective symptoms, so as to improve its predictive value.

Subjective memory complaint and its relationship with cognitive changes and physical vulnerability of community-dwelling older adults

Memory complaint (MC) is common in older adults and can be confirmed by people close to them, such as family members and caregivers. Studies show an association between MC and cognitive impairment and, hence, physical vulnerability may exacerbate MC. However, the relationship between MC and physical vulnerability is not yet clear in the literature.\.

Objective

to investigate the association between MC, cognitive impairment, and physical vulnerability.

Methods

this is a cross-sectional study. We evaluated 100 older adults with a mean age of 65 years or over. The Memory Complaint Scale (MCS), Addenbrooke's Cognitive Examination-Revised (ACE-R), Mini-Mental State Examination (MMSE), Vulnerable Elderly Research-13 (VES-13), Geriatric Depression Scale and a sociodemographic questionnaire were applied.

Results

participants were divided into two groups according to results on the MCS-A (elderly) and MCS-B (informant). Correlations were found between the MCS-A and the MMSE (p=.045/ρ=.201), ACE-R/Visual-Spatial (p=.048/ρ=.199), and ACE-R/Attention-Orientation (p=.026/ρ=.223). For the MCS-B, correlations were found with total score on the ACE-R (p=.044/ρ=-.202) and the ACE-R/Visual-Spatial (p=0.003/ρ=-.291).

Conclusion

MC reported by the informant indicate the need to assess, in more depth, the cognition of the older adult. Thus, for clinical practice, screening of MC through an informant is advised.

Quality of life and self-esteem among the elderly in the community

This study sought to investigate the association between the scores for quality of life (QoL) and self-esteem among the elderly in an urban community. A cross-sectional, quantitative and analytical household survey was conducted with 1,691 elderly persons resident in an urban area in a county in Minas Gerais state. The World Health Organization Quality of Life BREF (WHOQOL-BREF), the World Health Organization Quality of Life OLD (WHOQOL-OLD) questionnaires and the Rosenberg Self-Esteem Scale were used in this study. A descriptive statistical analysis and a linear regression model (p < 0.05) were conducted. The results revealed that the social relationships domain (71.19) and the topic of death and dying (74.30) had the highest mean scores among the elderly; while the lowest mean scores were the environment domain (60.39) and the topic of social participation (63.06). The self-esteem scores showed an average of 9.36 ± 4.09. Associations were evident for the lower scores of quality of life in all the WHOQOL-BREF domains and WHOQOL-OLD aspects (except death and dying) with lower levels of self-esteem (p <0.001). The results provide data that contribute to a better understanding of the aspects that influence the QoL of the elderly due to reduced self-esteem, thus providing information for the development of health strategies.

Subjective memory complaints and their relation with verbal fluency in active older people

Purpose

To verify subjective memory complaints and their relation to verbal fluency in older people participating in community groups.

Methods

An epidemiological quantitative study performed in community groups for older people in Florianópolis, state of Santa Catarina, Brazil. Data were collected by structured interview using the Memory Complaint Questionnaire (MAC-Q) and the Verbal Fluency Test (VFT) by semantic categories "animals/minute". For an inferential descriptive analysis, data with p < 5% were considered.

Results

Self-reported memory complaints were found in 35.7% of the sample. No association or correlation of VFT with the perception of memory obtained by MAC-Q, nor with its score was found. The VFT analysis of in individuals who reported negative perception of memory presented statistical significance. We found significant association between the perception (MAC-Q score) and presence of memory lapses (reported by the older people in question and added to the questionnaire).

Conclusion

We found no relation between subjective memory complaints and verbal fluency of active older people. Mnemonic complaints were correlated to the negative perception of memory and to the duration of the complaint. However, subjective memory complaints were an indicator for those individuals with negative perception of memory, being one aspect that must be considered in older people's speech when investigating a possible cognitive deterioration. Such data can assist in formulating public health care policies aimed at older people in the city, which emphasizes the importance of verifying subjective memory complaints in this population.
