Behavioral and psychological symptoms of dementia in the long-term care setting: assessment of aged adults and intervention for caregivers.

Due to the progressive need for care, older adults with dementia are at risk of becoming institutionalized. Caregivers of these patients are tasked with the challenge of controlling behavioral and psychological symptoms without sufficient knowledge and are therefore at greater risk of developing physical and mental health problems. In this context, psychoeducational interventions can help greatly toward improving caregiver well-being. Objective: to investigate the prevalence of behavioral and psychological symptoms of dementia (BPSD) in aged residents of long-term care facilities (LTCFs), to determine the prevalence of burden and common mental disorders in caregivers, and to assess the effects of a psychoeducational intervention. Methods: an intervention study was performed at LTCFs for aged people. The following instruments were used: Self-Reporting Questionnaire and Zarit Burden Interview for caregivers; and the MMSE, Katz Index, Clinical Dementia Rating scale and Neuropsychiatry Inventory-Questionnaire for older adults. Results: Of the 72 aged residents assessed, 52 (72.2%) were female and mean age was 82.3 (±8.14) years. The most prevalent neuropsychiatric symptoms were euphoria and elation (74%), followed by agitation and aggression (74%). Of the 54 caregivers, 49 (90.7%) were women and mean age was 33.9 (±10.8) years. Overall, 33.3% screened positive for common mental disorder and 36.1% for burden/overload. A statistically significant association was found between burden and working in philanthropic institutions (p=0.003) and also between burden and presence of common mental disorder or otherwise (p=0.001). After the psychoeducational intervention, 42.8% reported reduced burden. Conclusion: The residents presented neuropsychiatric symptoms. Caregivers showed burden and common mental disorders, especially in philanthropic institutions. It was observed a reduction in burden of caregivers with psychoeducational intervention, showing the importance of this strategy.

Em razão do aumento progressivo da necessidade de cuidados, idosos com demência apresentam risco de institucionalização. Os cuidadores desses pacientes são desafiados a controlar os sintomas comportamentais e psicológicos da demência sem o conhecimento adequado e, como resultado, estão em maior risco de adoecimento físico e emocional. Nesse contexto, a intervenção psicoeducacional contribui significativamente para a melhoria do bem-estar do cuidador. Objetivo: Investigar a prevalência de sintomas comportamentais e psicológicos na demência em idosos de instituições de longa permanência, verificar a prevalência de sobrecarga e transtorno mental comum nos cuidadores e avaliar os efeitos de uma intervenção psicoeducacional. Métodos: Estudo de intervenção realizado em instituições de longa permanência para idosos. Os instrumentos utilizados foram: Self-Reporting Questionnaire e Zarit Burden Interview para os cuidadores e o Miniexame do Estado Mental, Katz Index, Clinical Dementia Rating e Neuropsychiatry Inventory-Questionnaire para os idosos. Resultados: Dos 72 idosos, 52 (72,2%) eram mulheres, com média de idade de 82,3 (±8,14) anos. Os sintomas neuropsiquiátricos mais prevalentes foram: euforia e elação (74%) e agitação e agressividade (74%). Dos 54 cuidadores, 49 (90,7%) eram mulheres, com média de idade de 33,9 (±10,8) anos. Apresentaram rastreio positivo para transtorno mental comum 33,3% e para sobrecarga 36,1%. Foi encontrada associação estatisticamente significativa entre sobrecarga e trabalhar em instituições filantrópicas (p=0,003), assim como entre a sobrecarga e ter ou não transtorno mental comum (p=0,001). Após a intervenção psicoeducacional, 42,8% apresentaram redução da sobrecarga. Conclusão: Os residentes apresentaram sintomas neuropsiquiátricos. Os resultados dos cuidadores indicaram a presença de sobrecarga e outras manifestações em saúde mental, principalmente em instituições filantrópicas, além de demonstrar a importância de intervenções psicoeducativas voltadas aos cuidadores, considerando que foram observados efeitos na redução da sobrecarga para o grupo intervenção.

Association among inflammaging, body composition, physical activity, and physical function tests in physically active women.

Background: Inflammaging is a phenomenon that has been associated with the development and progression of sarcopenia and frailty syndrome. According to the literature, on the one side, the increase in body fat is associated with a systemic pro-inflammatory status, which consequently favors inflammaging, and on the other side, the regular practice of physical exercise can mitigate the development of this scenario. Therefore, here, we aimed to evaluate the association between inflammaging and physical factors, both body and functional, in a group of physically active older women. Methods: Seventy older women (mean age 72.66 ± 6.17 years) participated in this observational cross-sectional and were separated into the eutrophic, overweight, and obese groups. It was assessed: by bioimpedance-body fat percentage (Fat%) and total (Fat kg), skeletal muscle mass (muscle), and free fat mass both in percentage (FFM%) and total (FFMkg); by the International Physical Activity Questionnaire (IPAQ)-the time of moderate-intensity physical activity per week; by physical tests-handgrip (HG), sit-up-stand-on-the-chair in 5 repetitions (Sit-up) and vertical squat jump test (SJ); in addition to the determination of serum cytokine concentration (IL-6, TNF-α, IL-10, and IL-8), and also body mass index (BMI) and calf circumference (Calf). Results: Higher FFM% and lower body fat (both kg and %) were found in the eutrophic group than in the other groups. The eutrophic group also performed more weekly physical activity, jumped higher, and presented not only higher serum IL-6 concentration but also an increased ratio of IL-10/IL-6, IL-10/TNF-α, IL-10/IL-8 as compared to the values found in the overweight group. The obese group presented higher body fat (kg and %) and lower FFM% than the other groups and also higher serum IL-6 concentration than the overweight group. Interestingly, several significant negative and positive correlations between body composition, physical tests, and serum cytokine concentrations were found in the eutrophic and obese groups. Conclusion: While the eutrophic older women group showed a remarkable regulation of the systemic inflammatory status with positive associations in the physical parameters assessed, the overweight and obese groups presented impairment regulations of the inflammaging, which could be related to less weekly physical activity and higher body fat.

SARS-CoV-2 S1 Subunit Booster Vaccination Elicits Robust Humoral Immune Responses in Aged Mice

Currently approved COVID-19 vaccines prevent symptomatic infection, hospitalization, and death of the disease. However, the emergence of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) variants raises concerns of reduced vaccine effectiveness and increased risk of infection. Repeated homologous booster in elderly individuals and immunocompromised patients is considered to solve severe form of disease caused by new SARS-CoV-2 variants but cannot protect completely against breakthrough infection. In our previous study we assessed the immunogenicity of an adenovirus-based vaccine expressing SARS-CoV-2-S1 (Ad5.S1) in mice, resulting in that a single immunization with Ad5.S1, via subcutaneously injection or intranasal delivery, induced robust humoral and cellular immune responses [1]. As a follow up study, here we showed that vaccinated mice had high titers of anti-S1 antibodies at one year after vaccination compared to PBS immunized mice. Furthermore, one booster dose of non-adjuvanted recombinant S1Beta (rS1Beta) subunit vaccine was effective in stimulating strong long-lived S1-specific immune responses and inducing significantly high neutralizing antibodies against the Wuhan, Beta, and Delta strain with 3.6- to 19.5-fold change increases. Importantly, the booster dose elicits cross-reactive antibody responses resulting in ACE2 binding inhibition against spike of SARS-CoV-2 variants (Wuhan, Alpha, Beta, Gamma, Delta, Zeta, Kappa, New York, India) as early as two-week post-boost injection, persisting over 28 weeks after a booster vaccination. Interestingly, levels of neutralizing antibodies were correlated with not only level of S1-binding IgG but also level of ACE2 inhibition in the before- and after-booster serum samples. Our findings show that S1 recombinant protein subunit vaccine candidate as a booster has potential to offer cross-neutralization against broad variants, and has important implications for vaccine control of new emerging breakthrough SARS-CoV-2 variants in elderly individuals primed with adenovirus-based vaccine like AZD1222 and Ad26.COV2.S.

Impact of long-term care facilities' size on adherence to COVID-19' infection prevention guidance. / Impacto do tamanho das instituições de longa permanência na adesão às orientações de prevenção de infecções por COVID-19.

OBJECTIVE: to evaluate the adherence of Brazilian long-term care facilities to the World Health Organization Infection Prevention and Control guidance, and assess the association of their size with the adherence to these recommendations. METHOD: cross-sectional study conducted with facilities' managers. Authors developed a 20-item questionnaire based on this guidance, and a global score of adherence, based on the adoption of these recommendations. Adherence was classified as (1) excellent for those who attended ≥14 out of 20 recommendations; (2) good for 10 to 13 items; and (3) low for those with less than ten items. Facilities' sizes were established as small, intermediate, and large according to a two-step cluster analysis. Descriptive statistics and chi-square tests were used at a 5% significance level. RESULTS: among 362 included facilities, 308 (85.1%) adhered to 14 or more recommendations. Regarding its size, adherence to screening COVID-19 symptoms of visitors (p=0.037) and isolating patients until they have had two negative laboratory tests (p=0.032) were lower on larger ones compared to medium and small facilities. CONCLUSION: adherence to COVID-19 mitigation measures in Brazilian facilities was considered excellent for most of the recommendations, regardless of the size of the units.

Measurement properties of self-report instruments to assess health literacy in older adults: a systematic review.

BACKGROUND: High health literacy (HL) is important to optimise health outcomes, particularly for older people (who are substantial consumers of health services) and their adult caregivers. The aim of this systematic review was to evaluate measurement properties of HL instruments tested with these population groups. MATERIALS AND METHODS: Six databases (MEDLINE (OVID); CINAHL; EMBASE (OVID); PsycInfo; Scopus; Cochrane Library) were searched for studies evaluating eight measurement properties of HL tools administered to older people or their caregivers. Only studies evaluating multi-domain self-report HL tools were included in analyses, using the COSMIN methodology. RESULTS: From 4261 unique papers located, 11 met inclusion criteria; six reported measurement properties of three HL self-report tools administered to older people (HLQ, eHEALS, and HeLMS) so are reported in this review, none involved caregiver samples. The HLQ and HeLMS were rated "moderate," and eHEALS "low" for tool development. The HLQ, examined in four included studies, had the highest ratings and quality of evidence across the three measurement properties investigated in included papers. CONCLUSION: The HLQ was the most highly rated self-report HL tool of just three tested with older people. Further studies evaluating measurement properties of self-report HL tools used with older people and/or their caregivers are needed.Implications for rehabilitationHealth literacy is important to optimise health outcomes of interventions for older people and their adult caregivers.Few studies have evaluated measurement properties of self-report / multi-domain health literacy tools for this population.The Health Literacy Questionnaire (HLQ) had the highest ratings and quality of evidence across the three measurement properties investigated in included studies, and is recommended for use in rehabilitation settings.

Usability and acceptability of internet-based interventions for family carers of people living with dementia: systematic review.

Objectives: Internet-based interventions can help carers of people living with dementia to cope with care-related challenges and can help improve their wellbeing. This systematic review aimed at investigating the criteria of usability and acceptability of self-guided internet-based interventions for family carers of people living with dementia. Method: Searches were conducted on PubMed, Virtual Health Library Regional Portal (Americas), MEDLINE, PsycINFO, Scopus, and Cochrane. Studies published up to December 2019, in English, Portuguese, or Spanish, were eligible. We followed the definition/criteria from ISO ISO-9241-11 for usability (efficiency, effectiveness, and satisfaction) and acceptability (barriers for using and utility). Methodological quality was evaluated using specific tools according to each study design. Results: Ten studies were included, all of which had high methodological quality. Carers of people living with dementia indicated that internet-based interventions were mostly effective, efficient, and satisfactory. They considered these to be informative, relevant, and functional, highlighting the utility and intention of using the resource in the future. The high heterogeneity in the terms and methods used to evaluate usability and acceptability hindered cross-study comparisons, however internet-based interventions were considered useful and acceptable by most carers. Conclusion: Future research should consider expanding the criteria of usability and acceptability to better reflect the needs of this population.

Association between baseline Mini-Mental State Examination score and dementia incidence in a cohort of oldest old.

BACKGROUND: The Brazilian population has aged rapidly. The oldest old, defined as persons aged 80 years or older, is the fastest growing segment of the Brazilian population. Several instruments have been used to assess the cognitive performance of the older people and predict dementia. One of the most commonly used is the Mini-Mental State Examination (MMSE). OBJECTIVE: The aim of this study was to investigate the relationship between baseline MMSE score and the incidence of dementia in a Brazilian cohort of independent oldest old. METHODS: Sociodemographic data and serial cognitive assessment of 248 older adults were analyzed. RESULTS: Mean follow-up time of subjects was 4.0(±1.9) years, 71.4% were women, and mean MMSE score at entry was 25(±3.5). Mean MMSE scores at baseline were significantly higher (p=0.001) in the cognitively intact group than in those who developed dementia. The logistic regression showed that for a one point increase in MMSE score at baseline there was a 10% reduction in the probability of dementia. CONCLUSIONS: In the Brazilian scenario of a rapidly growing population of oldest old, the extensive use of the MMSE gives rise to the need not only to determine its effectiveness for screening dementia, but also to interpret its score in terms of future conversion to dementia.

RESUMO Antecedentes: A população brasileira envelheceu rapidamente. Os longevos, definidos como pessoas com 80 anos ou mais, são o segmento da população brasileira que mais cresce. Diversos instrumentos têm sido usados para avaliar o desempenho cognitivo de idosos e para predizer demência. Um dos instrumentos mais utilizados é o Miniexame do Estado Mental (MEEM). Objetivo: Nosso objetivo foi investigar a relação entre a pontuação inicial do MEEM e a incidência de demência em uma coorte brasileira de idosos longevos independentes. Métodos: Foram avaliados dados de 248 idosos por meio de um questionário sociodemográfico e de avaliações cognitivas seriadas. Resultados: O tempo médio de acompanhamento dos participantes foi de 4,0 (±1,9) anos. Eram mulheres 71,4% deles e a pontuação média do MEEM na entrada foi de 25 (±3,5) pontos. As pontuações médias do MEEM no início do estudo foram significativamente maiores (p=0,001) no grupo cognitivamente intacto do que naqueles que desenvolveram demência. A regressão logística mostrou que, para cada ponto a mais na pontuação do MEEM no início do estudo, houve redução de 10% na probabilidade de desenvolver demência. Conclusões: No cenário brasileiro de rápido crescimento da população de idosos longevos, o uso da ferramenta cognitiva mais amplamente utilizada cria a necessidade de determinar não apenas sua eficácia no rastreamento da demência, mas também de interpretar seu escore considerando-se a futura conversão para demência.

Immunity to SARS-CoV-2 up to 15 months after infection

BackgroundInformation concerning the longevity of immunity to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) following natural infection may have considerable implications for durability of immunity induced by vaccines. Here, we monitored the SARS-CoV-2 specific immune response in convalescent coronavirus disease-2019 (COVID-19) patients up to 15 months after symptoms onset. MethodsThe levels of anti-spike and anti-receptor binding domain antibodies and neutralizing activities were tested in a total of 188 samples from 136 convalescent patients who experience mild to critical COVID-19. Specific memory B and T cell responses were measured in 76 peripheral blood mononuclear cell samples collected from 54 patients. Twenty-three vaccinated individuals were included for comparison. FindingsFollowing a peak at day 15-28 post-infection, the IgG antibody response and plasma neutralizing titers gradually decreased over time but stabilized after 6 months. Plasma neutralizing activity against G614 was still detected in 87% of the patients at 6-15 months. Compared to G614, the median neutralizing titers against Beta, Gamma and Delta variants in plasma collected at early (15-103 days) and late (9-15 month) convalescence were 16- and 8-fold lower, respectively. SARS-CoV-2-specific memory B and T cells reached a peak at 3-6 months and persisted in the majority of patients up to 15 months although a significant decrease in specific T cells was observed between 6 and 15 months. ConclusionThe data suggest that antiviral specific immunity especially memory B cells in COVID-19 convalescent patients is long-lasting, but some variants of concern, including the fast-spreading Delta variant, may at least partially escape the neutralizing activity of plasma antibodies.

SARS-CoV-2 vaccine breakthrough infections are asymptomatic or mildly symptomatic and are infrequently transmitted.

Vaccine breakthrough SARS-CoV-2 infection has been monitored in 3720 healthcare workers receiving 2 doses of BNT162b2. SARS-CoV-2 infection is detected in 33 subjects, with a 100-day cumulative incidence of 0.93%. Vaccine protection against acquisition of SARS-CoV-2 infection is 83% (95%CI: 58-93%) in the overall population and 93% (95%CI: 69-99%) in SARS-CoV-2-experienced subjects, when compared with a non-vaccinated control group from the same Institution, in which SARS-CoV-2 infection occurs in 20/346 subjects (100-day cumulative incidence: 5.78%). The infection is symptomatic in 16 (48%) vaccinated subjects vs 17 (85%) controls (p=0.001). All analyzed patients, in whom the amount of viral RNA was sufficient for genome sequencing, results infected by the alpha variant. Antibody and T-cell responses are not reduced in subjects with breakthrough infection. Evidence of virus transmission, determined by contact tracing, is observed in two (6.1%) cases. This real-world data support the protective effect of BNT162b2 vaccine. A triple antigenic exposure, such as two-dose vaccine schedule in experienced subjects, may confer a higher protection.

Impact of long-term care facility size on preparedness and adherence to infection prevention and control guidance for the mitigation of COVID-19

AimTo evaluate the preparedness and adherence of Brazilian long-term care facilities (LTCFs) to the World Health Organization (WHO) infection prevention and control (IPC) guidance and examine the association of LTCF size with adherence to recommendations. MethodsWe conducted a cross-sectional study of LTCF managers for 12 consecutive weeks from May 5, 2020. We developed and pre-tested a 46-item questionnaire based on WHO IPC guidance that included multiple-choice and dichotomous questions as well as an open-ended question on the main difficulties encountered by the facility in tackling the pandemic. Using a global adherence score based on the adoption of 20 recommendations, we classified preparedness as (1) excellent for LTCFs following [≥]14 recommendations, (2) good for those following 10-13 recommendations, and (3) poor for those following <10 recommendations. LTCF size was established as small, medium, and large according to a 2-step cluster analysis of the number of residents as a continuous variable. We used descriptive statistics and chi-square tests at a 5% significance level. ResultsOf 362 facilities included in the study, 308 (85.1%) adhered to 14 or more recommendations; 3 were classified as poorly adherent. Regarding LTCF size, we found a lower adherence to screening visitors for COVID-19 signs and symptoms (p=0.037) and to isolating patients until they have 2 negative laboratory tests (p=0.032) in larger facilities than in medium and small facilities. ConclusionsPreparedness for mitigating COVID-19 in Brazilian LTCFs was considered excellent for most of the proposed recommendations, regardless of LTCF size. Difficulties and problems with infrastructure and/or resident care were much less commonly reported than those related to maintenance of a sufficient stock of materials, workforce management, and financial distress.

Knowledge and attitudes in dementia held by general practitioners in the primary care setting of Botucatu, São Paulo, Brazil.

BACKGROUND: Alzheimer's disease (AD) is the leading cause of dementia worldwide. Despite alarming evidence on dementia prevalence, the condition is still underdiagnosed by general practitioners (GPs) in primary care. Early detection of the disease is beneficial for patients and relatives, who should be provided comprehensive guidance on dealing with dementia complications, covering medical, family and social aspects, thereby providing an opportunity to plan for the future. OBJECTIVE: The objective of this study was to assess the knowledge of and attitudes toward dementia held by GPs from a city in the interior of São Paulo State, Brazil. METHODS: A non-randomized intervention study was conducted involving six lectures about dementia. Before and after the intervention, the participating physicians completed two quizzes about knowledge of and attitudes towards dementia. The study was carried out in the primary care services of the town and a total of 34 GPs participated in the study. RESULTS: The mean age of the sample was 33.9 (±10.2) years and the majority (76.5%) of the sample had not undertaken medical residency training. The mean number of correct answers on the Knowledge Quiz about dementia before and after the training intervention was 59.6 and 71.2% (p<0.001), respectively. The comparison of the mean responses on the Attitude Quiz revealed no statistically significant difference between the two applications of the instrument, before and after intervention (p=0.059). CONCLUSIONS: More training for GPs on dementia should be provided.

Influence of overcommitment on the quality of life and on climacteric symptoms in nursing professionals.

OBJECTIVE: To describe the general characteristics of nursing professionals and assess the influence of overcommitment on perceived climacteric symptoms and on the quality of life of nursing professionals. METHOD: A cross-sectional, analytical study of 152 nursing auxiliaries and assistants aged 40 years or older was conducted at 3 hospitals in the interior of São Paulo state. Sociodemographic data were collected and the Blatt-Kupperman Menopausal Index, Women´s Health Questionnaire, Medical Outcome Study 36-item Short Form Health Survey and Effort-Reward Imbalance were applied in 2017. A descriptive analysis was performed and network analysis was carried out. RESULTS: Participants had a mean age of 50.23 years (SD ±7.1). Group 1 comprising 61 (40.1%) women with overcommitment had poorer quality of life as well as more severe climacteric symptoms. CONCLUSIONS: Presence of overcommitment seems to influence the negative perception of climacteric symptomatology and quality of life.

Mapping Research Conducted on Long-Term Care Facilities for Older People in Brazil: A Scoping Review.

This scoping review aimed to explore the characteristics, strengths, and gaps in research conducted in Brazilian long-term care facilities (LTCFs) for older adults. Electronic searches investigating the residents (≥60 years old), their families, and the LTCF workforce in Brazil were conducted in Medline, EMBASE, LILACS, and Google Scholar, within the timescale of 1999 to 2018, limited to English, Portuguese, or Spanish. The reference lists were hand searched for additional papers. The Mixed Methods Appraisal Tool (MMAT) was used for critical appraisal of evidence. Data were reported descriptively considering the study design, using content analysis: 327 studies were included (n = 159 quantitative non-randomized, n = 82 quantitative descriptive, n = 67 qualitative, n = 11 mixed methods, n = 6 randomized controlled trials, and n = 2 translation of assessment tools). Regardless of the study design, most were conducted in a single LTCF (45.8%), in urban locations (84.3%), and in non-profit settings (38.7%). The randomized trials and descriptive studies presented the lowest methodological quality based on the MMAT. This is the first review to provide an overview of research on LTCFs for older people in Brazil. It illustrates an excess of small-scale, predominantly qualitative papers, many of which are reported in ways that do not allow the quality of the work to be assured.

Knowledge and attitudes in dementia held by general practitioners in the primary care setting of Botucatu, São Paulo, Brazil / Conhecimentos e atitudes em demência por parte de clínicos gerais do setor de atendimento primário de Botucatu, São Paulo, Brasil

ABSTRACT Background: Alzheimer's disease (AD) is the leading cause of dementia worldwide. Despite alarming evidence on dementia prevalence, the condition is still underdiagnosed by general practitioners (GPs) in primary care. Early detection of the disease is beneficial for patients and relatives, who should be provided comprehensive guidance on dealing with dementia complications, covering medical, family and social aspects, thereby providing an opportunity to plan for the future. Objective: The objective of this study was to assess the knowledge of and attitudes toward dementia held by GPs from a city in the interior of São Paulo State, Brazil. Methods: A non-randomized intervention study was conducted involving six lectures about dementia. Before and after the intervention, the participating physicians completed two quizzes about knowledge of and attitudes towards dementia. The study was carried out in the primary care services of the town and a total of 34 GPs participated in the study. Results: The mean age of the sample was 33.9 (±10.2) years and the majority (76.5%) of the sample had not undertaken medical residency training. The mean number of correct answers on the Knowledge Quiz about dementia before and after the training intervention was 59.6 and 71.2% (p<0.001), respectively. The comparison of the mean responses on the Attitude Quiz revealed no statistically significant difference between the two applications of the instrument, before and after intervention (p=0.059). Conclusions: More training for GPs on dementia should be provided.

RESUMO Introdução: A doença de Alzheimer é a principal causa de demência em todo o mundo. Apesar das evidências alarmantes sobre a prevalência de demência, a condição ainda é subdiagnosticada por clínicos gerais na atenção primária. A detecção precoce da doença é benéfica para pacientes e familiares, que devem receber orientações abrangentes sobre como lidar com as complicações relacionadas às demências, abrangendo aspectos médicos, familiares e sociais, proporcionando assim uma oportunidade de planejar o futuro. Objetivo: O objetivo deste estudo foi avaliar os conhecimentos e as atitudes em relação à demência por parte de clínicos gerais de uma cidade do interior de São Paulo, Brasil. Métodos: Foi realizado um estudo de intervenção não randomizado, envolvendo seis palestras sobre demência. Antes e depois da intervenção, os médicos participantes completaram dois questionários sobre conhecimentos e atitudes em relação à demência. O estudo foi realizado nos serviços de atenção primária da cidade e um total de 34 clínicos gerais participaram do estudo. Resultados: A idade média da amostra foi de 33,9 (±10,2) anos e a maioria (76,5%) da amostra não havia realizado treinamento em residência médica. O número médio de respostas corretas no Questionário do Conhecimento sobre demência antes e após a intervenção de treinamento foi de 59,6 e 71,2% (p<0,001), respectivamente. A comparação das respostas médias no questionário de atitudes não revelou diferença estatisticamente significativa entre as duas aplicações do instrumento, antes e após a intervenção (p=0,059). Conclusões: Deve ser fornecido mais treinamento sobre demência para os clínicos gerais.
