Sex- and age-specific impacts of smoking, overweight/obesity, hypertension, and diabetes mellitus in the development of disabling dementia in a Japanese population

BACKGROUND@#Sex- and age-specific impacts of cardiovascular risk factors on the development of dementia have not been well evaluated. We investigated these impacts of smoking, overweight/obesity, hypertension, and diabetes mellitus on the risk of disabling dementia.@*METHODS@#The study participants were 25,029 (10,134 men and 14,895 women) Japanese aged 40-74 years without disabling dementia at baseline (2008-2013). They were assessed on smoking status (non-current or current), overweight/obesity (body mass index ≥25 kg/m2 and ≥30 kg/m2, respectively), hypertension (systolic blood pressure ≥140 mmHg, diastolic blood pressure ≥90 mmHg or any antihypertensive medication use), and diabetes mellitus (a fasting serum glucose ≥126 mg/dL, non-fasting glucose ≥200 mg/dL, hemoglobin A1c ≥6.5% by the National Glycohemoglobin Standardization Program or glucose-lowering medication use) at baseline. Disabling dementia was identified as the level of care required ≥1 and cognitive disability grade ≥IIa according to the National Long-term Care Insurance Database. We used a Cox proportional regression model to estimate hazard ratios and 95% confidence intervals (95% CIs) of disabling dementia according to the cardiovascular risk factors and calculated the population attributable fractions (PAFs).@*RESULTS@#During a median follow-up of 9.1 years, 1,322 (606 men and 716 women) developed disabling dementia. Current smoking and hypertension were associated with a higher risk of disabling dementia in both sexes, whereas overweight or obesity was not associated with the risk in either sex. Diabetes mellitus was associated with a higher risk only in women (p for sex interaction = 0.04). The significant PAFs were 13% for smoking and 14% for hypertension in men and 3% for smoking, 12% for hypertension, and 5% for diabetes mellitus in women. The total PAFs of the significant risk factors were 28% in men and 20% in women. When stratified by age, hypertension in midlife (40-64 years) was associated with the increased risk in men, while diabetes mellitus in later-life (65-74 years) was so in women.@*CONCLUSIONS@#A substantial burden of disabling dementia was attributable to smoking, and hypertension in both sexes and diabetes mellitus in women, which may require the management of these cardiovascular risk factors to prevent dementia.

Influência da modalidade dialítica na cognição: uma revisão integrativa / Influence of the dialysis modality in cognition: an integrative review

A doença renal crônica é uma condição clínica caracterizada pela queda progressiva da função renal, interferindo na homeostase de todo o corpo, incluindo o sistema nervoso central. Nesses pacientes, o comprometimento cognitivo é um achado comum, em comparação com a população geral, e mais frequente nos pacientes em diálise. O objetivo deste estudo foi identificar, por meio de revisão integrativa, se há diferença entre a modalida- de dialítica (hemodiálise e diálise peritoneal) e a presença de comprometimento cognitivo nesses pacientes. Foi feito levan- tamento bibliográfico nas plataformas PubMed® e Bireme, com buscas padronizadas de 2014 até abril de 2019, utilizando-se pa- lavras-chave. Para a seleção e a avaliação dos estudos científicos levantados, foram estabelecidos critérios, contemplando os seguintes aspectos: autor, ano/local, grau de recomendação/ nível de evidência científica, amostra, faixa etária, média de idade em anos, métodos de avaliação, resultados e conclusão. Dos 561 artigos encontrados, 365 foram excluídos pela data de publicação, 87 foram excluídos pelo título, 17 pelo resumo, 49 pela leitura do artigo, 36 eram repetidos e oito foram selecio- nados para o estudo. Os pacientes em diálise peritoneal apre- sentaram menor comprometimento cognitivo e menor risco para demência que os pacientes em hemodiálise.

Chronic kidney disease is a clinical condition characterized by progressive decline in renal function, interfering with whole-bo- dy homeostasis, including the central nervous system. Cognitive impairment is a common finding in these patients, compared to the general population, besides being more frequent in dialysis patients. The objective of this study was to identify, through an integrative review, if there is difference between the dialysis mo- dality (hemodialysis and peritoneal dialysis) and the presence of cognitive impairment in these patients. A bibliographic search on the PubMed® and Bireme platforms, with standard searches from 2014 to April 2019, using keywords, was conducted. For the selection and evaluation of scientific studies found in the sear- ch, criteria have been established, considering the following as- pects: author, year/location, grade of recommendation/level of evidence, sample, age, mean age in years, evaluation methods, results, and conclusion. Among 561 articles found, 365 were ex- cluded based on the date of publication, 87 based on the title, 17 on the abstract, 48 on the article reading, 36 were repeated, and eight were selected for the study. Patients on peritoneal dialysis have less cognitive impairment and lower risk for dementia than patients on hemodialysis.

Hipoacusia como factor de riesgo para demencia

In the last decades, there has been an increase in life expectancy in the world, with the consequent modification in the proportion of adults over 60 years. This is accompanied by an increase in pathologies for which aging is the main risk factor, such as dementia and hearing loss, which profoundly affect the quality of life of individuals and their family and impact health system costs. Given the lack of disease-modifying treatments for dementia, the study of mechanisms to prevent its occurrence has become a world priority. In the year 2017, the Lancet "Commission for dementia prevention, intervention, and care" proposed a model, in which hearing loss emerged as a new modifiable risk factor for the development of dementia. This result undoubtedly has important consequences for the understanding the multifactorial nature of dementia, our daily clinical practice and public policies aimed at its prevention and treatment. In this article, we review the current evidence supporting the association between dementia and hearing loss, discussing the available strategies for prevention, detection and treatment of hearing loss and its possible impact on the natural course of dementia. A flow chart for the clinical management of different subgroups of patients is proposed.

Promotores de reserva cognitiva en adultos mayores con alto riesgo de demencia cortical / Promoters of Cognitive Reserve in the Elderly with High Risk of Cortical Dementia

Introducción: La reserva cognitiva constituye un elemento central para entender cómo responde el cerebro a la neuropatología durante el ciclo vital. Objetivo: Comprender los factores promotores de reserva cognitiva desde la experiencia de vida de adultos mayores sin deterioro cognitivo y con alto riesgo de demencia cortical. Métodos: Estudio cualitativo, con base en método Grounded Theory. Se realizan entrevistas semiestructuradas en profundidad a siete adultos mayores. En el análisis, se aplica la técnica de comparación constante según modelo de Glasser y Straus, utilizando Atlas ti/7. Resultados: Desde el análisis axial surgen cinco categorías interrelacionadas: actividad mental, experiencias gratificantes, cuidados, eventos traumáticos y características de personalidad. Se aprecia un patrón constante de experiencias vitales mentalmente estimulantes, relacionado principalmente a actividades de cuidado y experiencias gratificantes, no asociadas a educación formal. Conclusiones: Se distingue un proceso dinámico que involucra experiencias y eventos de vida cotidiana, tanto personales como ambientales, ocupacionales y del estilo de vida, que operan secuencialmente durante el ciclo vital; estos factores podrían incidir significativamente en los mecanismos neurobiológicos y actuar como promotores de reserva cognitiva. Se obtiene un modelo de promotores de reserva cognitiva que podría utilizarse en programas de salud cognitiva para contrarrestar la neuropatología(AU)

Introduction: Cognitive reserve constitutes an element central to understanding how the brain responds to neuropathology during the life cycle. Objective: To understand the factors that promote cognitive reserve from the life experience of the elderly without cognitive deterioration and with high risk of cortical dementia. Methods: Qualitative study, methodologically based on grounded theory. In-depth semi-structured interviews are conducted on seven elderlies. In the analysis, the constant comparison technique is applied according to the model by Glaser and Strauss, using ATLAS-Ti 7. Results: Five interrelated categories emerge from the axial analysis: mental activity, gratifying experiences, care, traumatic events, and personality traits. There is a constant pattern of mentally-stimulating life experiences, mainly related to care activities and gratifying experiences, not associated with formal education. Conclusions: A dynamic process is distinguished that involves experiences and events of daily life, both personal and environmental, occupational and related to lifestyle, which operate sequentially during the life cycle. These factors could significantly influence neurobiological mechanisms and act as promoters of cognitive reserve. A model of cognitive reserve promoters is obtained that could be used in cognitive health programs to counteract neuropathology(AU)

Enfermería, cuidadores principales y familia de pacientes con demencia / Nursing, Main Caregivers and the Families of Patients with Dementia

Introducción: La Organización Mundial de la Salud reconoce la demencia como una prioridad de salud pública. En Cuba, esta enfermedad ocupa un lugar importante entre las enfermedades crónicas no trasmisibles. Objetivo: Destacar la necesidad de una guía práctica para el personal de enfermería que trabaja con cuidadores principales de enfermos con demencia. Métodos: Se realiza una comunicación breve, en el municipio Marianao en La Habana en 2018 con 80 cuidadores principales, se relacionan los trastornos que estos presentan con más frecuencia con las necesidades humanas afectadas declaradas por enfermera teórica estadounidense Virginia Henderson. También se indagó acerca de las necesidades de aprendizaje del personal de enfermería que trabaja en el departamento de salud mental y se constató que resulta necesario la superación continua y estandarizar los cuidados hacia la familia con personas con demencia en la atención primaria. Conclusión: Una guía de práctica para el personal de enfermería que trabaja en atención primaria ayudaría a mejorar la calidad y estilos de vida de los cuidadores principales y la familia de los enfermos con demencia(AU)

Objective: To highlight the need for a practical guide for nurses who work with primary caregivers of patients with dementia. Methods: A brief research is carried out in Marianao Municipality, Havana, in 2018, including 80 main caregivers. The disorders that they present most frequently are related with the affected human needs declared by American theoretical nurse Virginia Henderson. We also investigated about the learning needs of the nursing staff working in the mental health department and it was found that continuous profesional upgrading was necessary, together with the standardization of care towards the family with people with dementia in primary care. Conclusion: A practice guide for nurses working in primary care would help improve the quality and lifestyles of the primary caregivers and the family of patients with dementia(AU)

Association of vitamin d with mild cognitive impairment and alzheimer's dementia in older mexican adults

ABSTRACT Background It has been proposed that Vitamin D helps reduce the accumulation of cerebral β-amyloid-42 by innate immune stimulation and phagocytosis activation. An association between low Vitamin D levels and Alzheimer’s dementia (AD) has been established. We determined the association between Vitamin D, mild cognitive impairment (MCI), and AD in older Mexican adults (> 65 years) Methods Cross-sectional study conducted at the memory clinic in a tertiary-level hospital in Mexico City. We evaluated subjects with MCI, AD, and normal cognition (NC) with available serum Vitamin D [25(OH)D] levels (past 6 months). Three categories were assigned according to 25(OH)D levels: sufficiency (> 30 ng/mL), insufficiency (21-29 ng/mL), and deficiency (≤ 20 ng/mL). Descriptive statistics, means and standard deviations were used. Logistic regression analyses adjusted by age, sex, and educational level were performed Results We evaluated 208 patients. Mean age was 79 ± 1 year, 65% (n = 136) were female; and mean educational level was 6.7 ± 2.3 years. Thirty-one subjects (14%) had NC; 42% (n = 88) had MCI; and 43% (n = 89) had AD. Prevalence of Vitamin D deficiency was 54%, more frequent in the AD group (64%) followed by the MCI (59%) and NC (13%) (p < 0.001) groups. In the multivariate logistic regression analysis, Vitamin D deficiency was associated with MCI (HR 25.02 [confidence interval 95% 4.48-139]; p < 0.001) and AD (HR 41.7 [5.76-301]; p < 0.001) after adjusting for confounders Conclusions Serum Vitamin D deficiency was associated with MCI and dementia; low levels produced a greater effect over executive functions.

Doença de Creutzfeldt-Jakob: relato de caso / Creutzfeldt-Jakob disease: case report

As doenças priônicas fazem parte do grupo das síndromes de demência rapidamente progressiva com neurodegeneração. Em humanos, a doença de Creutzfeldt-Jakob é a mais prevalente. Atualmente, seu diagnóstico pode ser baseado em uma combinação do quadro clínico, ressonância magnética e eletroencefalograma com alterações típicas, juntamente da detecção de proteína 14- 3-3 no líquido cefalorraquidiano. Este relato descreve o caso de uma paciente de 74 anos, natural de Ubá (MG), admitida em um hospital da mesma cidade com quadro de demência de rápida progressão, com declínio cognitivo, ataxia cerebelar e mioclonias. No contexto clínico, aventou-se a possibilidade de doença de Creutzfeldt-Jakob e, então, foi iniciada investigação para tal, com base nos critérios diagnósticos. Também foram realizados exames para descartar a possibilidade de doenças com sintomas semelhantes. O caso foi diagnosticado como forma esporádica de doença de Creutzfeldt-Jakob. (AU)

Prion diseases are part of the rapidly progressive dementia syndromes with neurodegeneration. In humans, Creutzfeldt-Jakob disease is the most prevalent. Currently, its diagnosis may be based on a combination of clinical picture, magnetic resonance imaging, and electroencephalogram with typical changes, along with the detection of 14-3-3 protein in cerebrospinal fluid. This report describes the case of a 74-year-old woman from the city of Ubá, in the state of Minas Gerais, who was admitted to a hospital in the same city with a rapidly progressive dementia, cognitive decline, cerebellar ataxia and myoclonus. In the clinical context, the possibility of Creutzfeldt-Jakob disease was raised, and then investigation was started for this disease, based on the its diagnostic criteria. Tests have also been conducted to rule out the possibility of diseases with similar symptoms. The case was diagnosed as a sporadic form of Creutzfeldt-Jakob disease. (AU)

Los problemas auditivos aumentan el riesgo de deterioro cognitivo en adultos mayores chilenos / Hearing impairments increase the risk of cognitive impairment in older Chilean adults

RESUMEN Introducción: Estudios previos han asociado la pérdida auditiva con un acelerado deterioro cognitivo durante el envejecimiento; no obstante, esta asociación no ha sido estudiada en adultos mayores chilenos. Objetivo: Investigar la asociación entre la discapacidad auditiva y la sospecha de deterioro cognitivo a través del cuestionario Mini Mental State Examination (MMSE, versión abreviada) en esta población. Material y método: Se incluyeron 1.384 adultos mayores de 60 años de la encuesta nacional de salud 2009-2010. Un puntaje <13 puntos en el MMSE se consideró sospecha de deterioro cognitivo. La discapacidad auditiva se determinó a través de un cuestionario de tamizaje autorreportado de tres preguntas. La asociación entre estas dos variables se investigó mediante análisis de regresión logística. Resultados: Se identificó una asociación significativa entre el MMSE alterado y cada una de las discapacidades auditivas estudiadas. A su vez, existió una tendencia a aumentar en 59% la probabilidad de desarrollar deterioro cognitivo en la medida que aumentaron las discapacidades auditivas (OR: 1,59 [95% IC: 1,38 a 1,82], p <0,0001). Conclusión: La disminución de la percepción auditiva es un factor de riesgo para el desarrollo de deterioro cognitivo y posteriormente demencia. La creación de políticas públicas, orientadas al tamizaje temprano en población de riesgo, podría ser una solución efectiva para prevenir las consecuencias asociadas con esta condición.

ABSTRACT Introduction: Hearing loss has been associated with an accelerated cognitive impairment during ageing. However, this association has not been investigated in older Chilean adults. Aim: To investigate the association between hearing impairment and cognitive impairment, using the Mini-Mental State Examination (MMSE, abridged version), in the Chilean population. Material and methods: 1,384 older adults aged ≥60 years, from 2009-2010 Chilean national health survey, were included. <13 points in the MMSE were considered suspicion of cognitive impairment. Hearing impairment was determined through a questionnaire including 3 domains. The association between cognitive and hearing loss was investigated using logistic regression. Results: An association between MMSE and each hearing disabilities studied was identified. As hearing impairments increased, the odd for cognitive impairment incremented by 59% (OR: 1.59 [95% IC: 1.38 a 1.82], p <0.0001). Conclusion: Hearing loss is a risk factor to develop cognitive impairment, which could translate into a high risk of dementia. Public politics implementation, focused in an early screening, could be an effective approach to prevent the complications associated with this hearing loss in older adults.

Tasas corregidas de mortalidad atribuible a la demencia por la enfermedad de Alzheimer, Brasil, 2009-2013 / Taxas corrigidas de mortalidade atribuíveis à demência pela doença de Alzheimer, Brasil, 2009-2013 / Adjusted mortality rates attributable to Alzheimer's disease dementia, Brazil, 2009-2013

Este artículo proporciona estimaciones de las tasas de mortalidad por la demencia por la enfermedad de Alzheimer (DA) en población adulta mayor. Para ello, se usaron datos del Censo Demográfico de 2010 del Instituto Brasileño de Geografía y Estadística (IBGE) y microdatos de mortalidad de las 27 capitales de los estados brasileños, registradas en el Sistema de Informaciones sobre Mortalidad (SIM) del Ministerio de Salud de Brasil, en población con 65 años o más por lugar de residencia, entre los años 2009 y 2013. Se obtuvieron correcciones de los subregistros de mortalidad y ajustes finales de las tasas específicas de mortalidad, a partir de métodos bayesianos, con distribuciones de probabilidad a priori, construidas en base a información obtenida desde metaanálisis. Se destaca que las tasas por demencia y DA en Brasil fueron superiores a las obtenidas en países desarrollados. Las tasas de mortalidad por Alzheimer en 2013 fueron de 140,03 (IC95%: 117,05; 166,4) y 127,07 (IC95%: 103,74; 149,62) por 100.000 habitantes, respectivamente, en hombres y mujeres. La contribución de la DA a la mortalidad adulta mayor en el Brasil fue 4,4% (IC95%: 3,25; 5,72), en el grupo de personas de 0 a 3 años de estudio, independiente de la edad y sexo. Nuestras contribuciones fueron dirigidas a aumentar el conocimiento en estimaciones corregidas de las tasas de mortalidad por Alzheimer con base en estadísticas vitales, proporcionando estimaciones más precisas y pertinentes, fundamentadas en el método científico.

Este artigo oferece estimativas das taxas de mortalidade devidas à demência pela doença de Alzheimer (DA) na população idosa brasileira. Para isso, foram usados dados do Censo de Demográfico de 2010 do Instituto Brasileiro de Geografia e Estatística (IBGE) e microdados de mortalidade das 27 capitais dos estados brasileiros, registradas no Sistema de Informações sobre Mortalidade (SIM) do Ministério da Saúde, em população com 65 anos ou mais por local de residência, entre os anos de 2009 e 2013. Foram obtidas correções dos sub-registros de mortalidade e ajustes finais das taxas específicas de mortalidade, a partir de métodos bayesianos, com distribuições de probabilidade a priori, construídas em base a informações obtidas via meta-análises. Foi destacado que as taxas por demência e DA no Brasil foram superiores às obtidas em países desenvolvidos. As taxas de mortalidade por Alzheimer em 2013 foram de 140,03 (IC95%: 117,05; 166,4) e 127,07 (IC95%: 103,74; 149,62) por 100 mil habitantes, respectivamente, em homens e mulheres. A contribuição da DA para a mortalidade em idosos no Brasil foi 4,4% (IC95%: 3,25; 5,72), em um grupo de pessoas com 0 a 3 anos de estudo, independentemente da idade ou sexo. Nossas contribuições foram dirigidas a aumentar o conhecimento em estimativas corrigidas das taxas de mortalidade por Alzheimer com base em estatísticas vitais, proporcionando estimativas mais precisas e pertinentes, fundamentadas no método científico.

This paper provides estimates of mortality rates from Alzheimer's disease dementia (AD) in the elderly Brazilian population. Data were obtained from the 2010 Population Census by Brazilian Institute of Geography and Statistics (IBGE) and microdata on mortality in Brazil's 27 state capitals recorded in the Brazilian Mortality Information System (SIM) for the population 65 years or older by place of residence for the years 2009 to 2013. Corrections were obtained for underreporting of mortality, and final adjustments were made to the specific mortality rates based on Bayesian methods with prior probability distributions built on the basis of information obtained from a meta-analysis. The mortality rates from all dementias and from AD in Brazil were higher than in developed countries. The mortality rates from Alzheimer's disease in 2013 were 140.03 (95%CI: 117.05; 166.4) and 127.07 (95%CI: 103.74; 149.62) per 100,000 inhabitants, respectively, in men and women. The contribution of AD to mortality in elderly Brazilians was 4.4% (95%CI: 3.25; 5.72) in the group with 0 to 3 years of schooling, independently of age and sex. The study aimed to increase knowledge on corrected estimates of mortality rates from Alzheimer's disease based on vital statistics, providing more precise and pertinent evidence-based estimates.

Deterioro Conductual Leve (MBI), Deterioro Cognitivo Leve (MCI) y desarrollo de la demencia: implicancias diagnósticas y clínicas / Mild Behavioral Impairment (MBI), Mild Cognitive Impairment (MCI) and development of dementia: diagnostic and clinical implications

Tanto el Deterioro Conductual Leve (MBI) y el Deterioro Cognitivo Leve (MCI) han sido identificados como estados o fases predemenciales. Estas entidades constituyen factores de riesgo para el desarrollo de las demencias y en muchos casos, una manifestación temprana de las mismas. En este contexto, los síntomas neuropsiquiátricos que caracterizan al MBI no solo podrían presentarse concurrentemente con el MCI, sino también antes de su aparición o incluso sin que este se llegara a presentar. Esta aparición selectiva del MBI sigue representando un gran desafío en términos de la comprensión de su etiología y el sustrato neurobiológico que podría compartir con el MCI. En este artículo se presentan las características centrales del MBI, los criterios que se emplean para su diagnóstico, las relaciones que guarda con el MCI y sus posibles biomarcadores, para discutir algunos aspectos relacionados con su diagnóstico clínico

Malestar psicológico en cuidadores principales de pacientes con enfermedad de Alzheimer / Psychological uneasiness in principal caregivers of patients with Alzheimer's disease

RESUMEN Introducción: En el transcurso de la vida todos somos cuidadores de algún modo. Sin embargo, aprender a serlo no surge de forma automática. Con el gradual envejecimiento de la población aumenta el número de casos que necesitan cuidados. La enfermedad de Alzheimer produce la pérdida gradual de la capacidad de cuidar de sí mismo y por ende se necesita la ayuda de un cuidador familiar, quien asume las principales tareas de cuidado y contrae una gran carga física y psíquica. Objetivo: Caracterizar el malestar psicológico que experimentan los cuidadores principales de pacientes con enfermedad de Alzheimer en los estadios leve y moderado. Métodos: Estudio descriptivo en 35 cuidadores principales de pacientes con enfermedad de Alzheimer leve y moderada del policlínico "Carlos Manuel Portuondo", municipio Marianao. La información fue recogida con el Inventario Neuropsiquiátrico validado al castellano, se procesó con distribuciones de frecuencia absoluta y porcentaje. Resultados: En la categoría de mínimo, predominaron la agitación o agresión (20,00 por ciento), las alteraciones del sueño (22,85 por ciento) y los trastornos de hábitos alimentarios (25,71 por ciento). En la categoría ligero, prevalecieron la depresión (20,00 por ciento), las alteraciones del sueño (25,71 por ciento) y los trastornos de hábitos alimentarios (22,85 por ciento). En la categoría de moderado, los síntomas más frecuentes fueron las repeticiones (25,71 por ciento), la depresión y la ansiedad, ambos con un 22,85 por ciento, la apatía y la irritabilidad, con un 20,00 por ciento. En la categoría de severo, el SPC más frecuente fue las repeticiones (20,00 por ciento). Conclusiones: En los cuidadores principales de pacientes con enfermedad de Alzheimer en los estadios leve y moderado predominó el malestar mínimo, ligero y moderado, presentaron mayor malestar ante la presencia de agitación o agresión, alteraciones del sueño, trastornos de hábitos alimentarios, depresión, repeticiones, ansiedad, apatía e irritabilidad(AU)

ABSTRACT Introduction: In the course of our lives, we are all caregivers in some way. However, learning how to be one does not come up automatically. With an increase in population aging, the number of cases of people needing care also increases. Alzheimer's disease produces the gradual loss of the capacity to take care of oneself and therefore there is the need for the help of a family caregiver, who assumes the main caring tasks together with great physical and mental burden. Objective: To characterize the psychological distress experienced by the main caregivers of patients with Alzheimer's disease in the mild and moderate stages. Methods: Descriptive study with 35 main caregivers of patients with mild and moderate Alzheimer's disease of Carlos Manuel Portuondo Polyclinic of Marianao Municipality. The information was collected with the Neuropsychiatric Inventory validated in Spanish, processed with absolute frequency and percentage distributions. Results: In the category minimum, agitation or aggression (20.00 percent), sleep disturbances (22.85 percent) and eating habits disorders (25.71 percent) predominated. In the category light, depression (20.00 percent), sleep disturbances (25.71 percent) and eating habits disorders (22.85 percent) prevailed. In the category moderate, the most frequent symptoms were repetitions (25.71 percent), depression and anxiety, both with 22.85 percent, apathy and irritability, with 20.00 percent. In the category severe, the most frequent SPC was the repetitions (20.00 percent). Conclusions: In the main caregivers of patients with Alzheimer's disease in the mild and moderate stages, the minimum, slight and moderate discomfort prevailed. They presented greater discomfort in the presence of agitation or aggression, sleep disturbances, eating disorders, depression, repetitions, anxiety, apathy and irritability(AU)

Determinantes del estado de salud de la población y su influencia en el desarrollo de los trastornos cognitivos / Determinants of the health status of the population and its influence on the development of cognitive disorders

Introducción: Ante el envejecimiento acelerado de la población cubana los trastornos cognitivos se han convertido en creciente problema y un reto para nuestro sistema de salud. Objetivo: Describir la influencia de las determinantes del estado de salud de la población en el desarrollo de los trastornos cognitivos. Fuente de datos: Se consultaron 113 artículos en la Biblioteca Virtual Scielo y en las bases de datos Medline, Google Scholar, Cochrane y PubMed, en idioma Inglés y Español. Se seleccionaron 40, publicados en revistas nacionales e internacionales de gran impacto, por autores considerados expertos en esta temática. Síntesis de los datos: Además de factores biológicos y genéticos, existen determinantes psicosociales como el nivel educacional y los estilos de vida que pudieran incidir en la aparición y desarrollo de las demencias. Entre estos últimos, aparecen los hábitos tóxicos, las relaciones sociales, antecedentes de depresión, nivel socioeconómico y otros. Conclusiones: La influencia de los determinantes del estado de salud de la población en el desarrollo de los trastornos cognitivos, es notable. Es necesario el estudio de estos determinantes y su contribución a la puesta en marcha de estrategias de intervención comunitaria que ayuden, sobre todo, a la población más vulnerable a tener una mejor calidad de vida(AU).

Introduction: The accelerated aging of the Cuban population is an alert to the high prevalence of dementias and other chronic diseases. Objective: To describe the influence of health status determinants of the population in the development of cognitive disorders. Data source: 113 articles in the Scielo Virtual Library and in Medline, Google Scholar, Cochrane and PubMed databases were consulted, both in English and Spanish. 38 of the selected were published in national and international magazines of great impact, by authors considered experts in this subject. Synthesis of data: In addition to biological and genetic factors, there are other psychosocial determinants such as education and lifestyles that may have an impact on the onset and development of dementia. Among the latter are toxic habits, social interactions, sleep, and depressive states. These states may be considered as a psychological reaction to incipient cognitive worsening or as an early manifestation of dementia. Conclusions: The influence of population´s health status determinants in the development of cognitive disorders is remarkable. Given the accelerated aging of the Cuban population, cognitive disorders become a growing health problem. More research is needed and the results of this may contribute to a better understanding of the epidemiological behavior of these disorders. It is necessary, through intersectoral work, the implementation of community intervention strategies that help above all most vulnerable population to have a better life quality(AU)

Algunos determinantes sociales y su impacto en las demencias / Some social determinants and their impact on dementia

Objetivos: Describir la influencia de los determinantes propios del individuo y los determinantes sociales macroeconómicos en la prevalencia de las personas con demencia así como el rol de las políticas de salud en el control de la enfermedad.nFuente de datos: Se consultaron las bases Pubmed (3 811 artículos), Ebsco (450), y Google Scholar (1 330). Se obtuvieron 5 591 artículos, se seleccionaron 54, de estos, 46 en idioma inglés y 8 en español. Síntesis de los datos: Los determinantes de la salud propios del individuo: edad, sexo, raza o grupos étnicos aportan información que puede influir en el desarrollo de la demencia y pueden ser modificados por factores ambientales como el estilo de vida y las redes sociales. Se abordan los determinantes sociales macroeconómicos como los costos y los planes nacionales para la atención a la demencia. El costo mundial de la enfermedad se distribuye de forma desigual, con predominio de los países más ricos. Cuba, Costa Rica y México son los primeros países de medianos y bajos ingresos que comenzaron a desarrollar estrategias nacionales para la atención a la demencia. Conclusiones: La demencia puede estar influenciada por factores de riesgo en la edad media de la vida: obesidad, hábito de fumar, sedentarismo, hipercolesterolemia, alcoholismo y bajo nivel educacional. Los planes nacionales para la demencia aumentan la calidad de la atención médica, optimizan los servicios de salud y logran una mayor equidad. Es una necesidad que los países en desarrollo incrementen su colaboración mutua y tracen estrategias para enfrentar esta enfermedad(AU)

Objectives: To describe the influence of the individual´s determinants and of the macroeconomic social determinants in the prevalence of people with dementia as well as the role of the health policies in the disease control. Data source: Pubmed (3 811 articles), Ebsco (450), and Google Scholar (1 330) were consulted in. In the review, 5 591 articles were obtained, 57 were selected of which 49 in English language and 8 in Spanish. Data synthesis: Individual´s health determinants such as age, sex, race or ethnic groups provide information that can influence in the development of dementia and they can be modified by environmental factors like the lifestyle and the social networks. The macroeconomic social determinants such as the costs and the national plans for dementia care were also analyzed. The world cost of the illness is unequally distributed, with prevalence of the richest countries. Cuba, Costa Rica and Mexico are the first countries of medium and low incomes that are developing national strategies for dementia care. Conclusions : Dementia can be influenced by risk factors in the middle age such as obesity, smoking, hypercholesterolemia, alcoholism and low educational level. The national plans for dementia increase the quality of the medical care, maximize the health care services and achieve greater equity. It is required that the developing countries increase mutual cooperation and draw strategies to cope with this disease(AU)

Survival and Functional Outcomes after Hip Fracture among Nursing Home Residents

Following the implementation of a long-term care insurance system for the elderly in Korea, many nursing homes have been established and many more patients than ever before have been living at nursing homes. Despite the fact that this is a high-risk group vulnerable to hip fractures, no study has yet been conducted in Korea on hip fracture incidence rates and prognoses among patients residing at nursing homes. We recently studied 46 cases of hip fracture in nursing homes; more specifically, we investigated the most common conditions under which fractures occur, and examined the degree of recovery of ambulatory ability and the mortality within 1 yr. Among those who had survived after 1 yr, the number of non-functional ambulators increased from 8 hips before hip fracture to 19 hips at final post-fracture follow-up. These individuals showed poor recovery of ambulatory ability, and the number who died within one year was 11 (23.9%), a rate not significantly different from that among community-dwelling individuals. It was evident that hip-joint-fracture nursing home residents survived for similar periods of time as did those dwelling in the community, though under much more uncomfortable conditions. The main highlight of this report is that it is the first from Korea on nursing home residents' ambulatory recovery and one-year mortality after hip fracture. The authors believe that, beginning with the present study, the government should collect and evaluate the number of hips fractured at nursing facilities in order to formulate criteria that will help to enable all patients to select safer and better-quality nursing facilities for themselves or their family members.

Aspects tomodensitometriques des demences au Togo

Introduction : La demence est une pathologie en rapport avec l'age dont la prevalence est en progression dans le monde; et en particulier dans les pays en developpement. L'objectif de cette etude etait de determiner les aspects tomodensitometriques des demences au Togo. Patients et Methodes : Il s'agit d'une etude prospective et analytique portant sur 144 patients durant la periode allant de janvier 2011 a decembre 2012. Etaient inclus a l'etude; tout patient presentant une deterioration des fonctions superieures et ayant beneficie d'une tomodensitometrie (TDM) cerebrale. L'examen tomodensitometrique avait ete realise sur un scanner de 16 barrettes de marque General Electric; avec des acquisitions volumiques sans et avec injection du produit de contraste (en cas de necessite) suivies de reconstructions coronales. Resultats : Au total 2320 TDM cerebrales avaient ete realisees pendant la periode d'etude dont 144 pour deterioration des fonctions superieures (6;2). La repartition des patients en fonction de l'age montre une predominance masculine (sex ratio = 1;5). La frequence de la pathologie augmentait avec l'age avec une moyenne de 60 ans. Les causes curables avaient ete retrouvees chez 41 patients (28;5); dominees par l'hydrocephalie chronique de l'adulte. Les causes non curables representaient 78 patients (54;2). La TDM etait normale chez 25 patients (17;3). Conclusion : La tomodensitometrie peut etre suffisante dans l'exploration des demences dans les pays en developpement ou l'acces a l'imagerie par resonnance magnetique est limite

Demencia por déficit de vitamina B12: reporte de caso / Dementia caused by deficiency of vitamin B1: a case report

La deficiencia de vitamina B12 (cianocobalamina) puede producir varios desórdenes neurológicos, incluida la neuropatía periférica, degeneración subaguda combinada de la médula espinal, neuropatía óptica y alteraciones cognitivas que van desde la confusión leve hasta la demencia o la psicosis. La causa más frecuente de deficiencia de vitamina B12 es la anemia perniciosa.Objetivo: presentar un caso clínico de demencia por déficit de vitamina B12.Caso clínico: paciente masculino de 50 años de edad, casado, trabajador por cuenta propia, presentó un cuadro de inicio insidioso con fallas de memoria, apatía y depresión. Progresivamente se agregaron conductas inadecuadas, ideas delirantes de persecución y desorientación espacial, por lo cual debió dejar el trabajo. El examen mental de ingreso mostró notoria bradipsiquia, con apatía y actitud suspicaz. Manifestó desorientación temporoespacial, conductas de imitación y perseverancia, fallo de la memoria, con confabulaciones y falsos reconocimientos. Hemograma: anemia macrocítica, con hematocrito 29l/l neutrófilos polisegmentados. El nivel de vitamina B12 fue 0 pg/ml (normal >179 pg). En la lámina periférica se encontró macrocitosis, poiquilocitosis, dianocitos, crenocitos, leucocitosis ligera con neutrofilia, trombocitopenía ligera con macroplaquetas.Conclusiones: la demencia por déficit de vitamina B12 es una afección rara pero se han reportado casos en la literatura médica...

Deficiency of vitamin B12 (cyanocobalamin) can produce some neurological disorders like peripheral neuropathy, subacute combined degeneration of spinal cord, optic neuropathy, as well as cognitive alterations that go from mild confusion to dementia or psychosis. The most frequent cause of deficiency of vitamin B12 is pernicious anemia.Objective: to present a clinical case of dementia caused by deficit of vitamin B12.Clinical case: a fifty-year-old male patient who is married and a self-employed worker, presented manifestations of insidious beginning with memory failure, apathy, and depression. Progressively, an inadequate conduct, delirious ideas of pursuit and spatial disorientation were added to the manifestations; that’s why he had to stop working. The mental test when admitted showed bradypsychia, apathy and a suspicious behaviour.Conclusions: dementia caused by deficiency of vitamin B12 is a rare complaint but some cases have been reported in the medical literature...

Syphilitic dementia presenting with Adie's tonic pupil and mesial temporal lobes hyperintensities / Demência sifilítica apresentando pupila tônica de Adie e hiperintensidades temporais mesiais

Syphilis became a rare cause of dementia in the present days. Screeningtests for syphilis are no longer recommended according to 2001.American Academy of Neurology guidelines. On the other hand, as itmay represent a potentially treatable cause in developing countries,the Academia Brasileira de Neurologia recommends laboratory screeningfor syphilis in patients with dementia. The diagnosis of neurosyphilisis established with basis on the clinical setting, along withtreponemal and non-treponemal serum antibodies, and cerebrospinalfluid pattern. Magnetic resonance imaging generally reveals cortical atrophy. Focal signs in the temporal lobes are rarely seen. A case of a young man diagnosed with neurosyphilis is presented, on the basis of neuropsychiatric symptoms, uncommon pupillary changes (Adie's tonic pupil), CSF with positive FTA-abs, and increased IgG index, and additionally mesial temporal lobes hypersignal changes.

Considera-se neurossífilis uma causa rara de demência atualmente.Testes para investigação de sífilis não são mais recomendados deacordo com as orientações da Academia Americana de Neurologia,de 2001. Por outro lado, como pode representar uma causa potencialmente tratável, a Academia Brasileira de Neurologia recomendaa investigação de sífilis em pacientes com demência. O diagnósticode neurossífilis é estabelecido pelo quadro clínico em associaçãocom anticorpos treponêmicos e não treponêmicos, e exame de LCR.Ressonância magnética revela, em geral, atrofia cortical. Presençasde sinais focais em lobos temporais são consideradas raras. É apresentado caso de homem jovem com diagnóstico de neurossífilis combase nas manifestações neuropsiquiátricas, alteração incomum aoexame pupilar (pupila de tônica de Adie), LCR com FTA-abs positivoe índice de IgG elevado, e ainda hipersinal nos lobos temporais mesiais.

Posterior cortical atrophy - a prototypical case of dementia beginning with visual symptoms: case report / Atrofia cortical posterior - um caso prototípico de demência iniciando com sintomas visuais: relato de caso

Dementia presenting with prominent higher order visual symptoms may be observed in a range of neurodegenerative conditions and is often challenging to diagnose. We describe a case of progressive dementia presenting with prominent visual cortical symptoms. A 55-year-old, right-handed, woman with early onset of visual impairment not associated with anterior visual pathology, presenting with dyslexia, visual agnosia, Balint's syndrome, and spatial disorientation. Ophthalmologists should consider this condition especially in presenile patients with slowly progressive higher-order visual symptoms. Although described in association with different conditions, it may also occur in Alzheimer disease.

As demências que se apresentam predominantemente com sintomas visuais associativos podem ser observadas em diferentes condições neurodegenerativas, sendo seu diagnóstico muitas vezes desafiador. Descrevemos um caso com demência progressiva que se apresentam com sintomas visuais proeminentes. Mulher de 55 anos, destra, com início precoce de déficits visuais não associados a patologia visual anterior, apresentando dislexia, agnosia visual, síndrome de Balint e desorientação espacial. Os oftalmologistas devem ter em mente essa condição especialmente em pacientes pré-senis com queixas visuais complexas e lentamente progressivas. Apesar de descritas em diferentes condições, pode ocorrer na doença de Alzheimer.

Uso de aparelho de amplificação sonora individual por idosos: estudo SABE - saúde, bem- estar e envelhecimento / Hearing aids use among elderly: SABE study - health, well-being and aging survey

OBJETIVO: Descrever o uso do aparelho de amplificação sonora individual (AASI) pela população idosa do município de São Paulo e fatores associados. MÉTODOS: Estudo transversal, descritivo e quantitativo, integrante do Estudo SABE (Saúde, Bem-estar e Envelhecimento), desenvolvido no ano de 2006. Foram entrevistados 1115 sujeitos com 65 anos ou mais. A amostra foi obtida de setores censitários em dois estágios, com reposição e probabilidade proporcional à população, complementando-se para acima de 75 anos. Utilizou-se questionário estruturado e instrumentos validados. Os dados foram ponderados e a análise foi realizada no software Stata 10®, através do teste de Rao-Scott para análise univariada e regressão logística tipo stepwise backward para análise multivariada. RESULTADOS: Trezentos e setenta e sete sujeitos (30,4%) apresentaram deficiência auditiva autorreferida e destes, 10,1% declararam utilizar o AASI. Dentre as formas de aquisição do dispositivo, 78,8% utilizaram recursos particulares e 16,9% adquiriram via Sistema Único de Saúde (SUS). Dentre os não protetizados, 16,6% relataram indicação prévia. Entretanto, 8,6% não se acostumaram e 8,0% não adquiriram, por problemas financeiros. O uso do AASI associou-se à menor prevalência de provável demência. CONCLUSÃO: O baixo número de usuários de AASI indica dificuldades dos idosos em adquiri-lo e/ou dos serviços de saúde em adaptá-los de forma efetiva. Esse achado pode influenciar a qualidade de vida do idoso deficiente auditivo, visto a associação com a provável demência, revelada pelo presente estudo.

PURPOSE: Describe hearing aid use by the elderly population in the city of São Paulo and identify associated factors. METHODS: A cross-sectional, descriptive, quantitative study integrated with the SABE (health, well-being and aging) project developed in 2006. A total of 1.115 individuals aged 65 or over were interviewed. Sample selection occurred in two stages, with replacement and probabilities proportional to the population to complement those aged 75 or over. Structured questionnaires and validated instruments were used. The data were weighted, the Rao-Scott test was used for univariate analysis and backward stepwise logistic regression was used for multivariate analysis, performed on Stata 10® software. RESULTS: Three hundred and seventy-seven subjects (30.4%) were classified as hearing impaired and 10.1% of these reported using hearing aids. To acquire the devices, 78.8% used their own resources and 16.9% acquired them through the Brazilian public health system (SUS). Among non-users of hearing aids, 16.6% reported prior indication; however, 8.6% were unable to adapt to the device and 8.0% could not afford to acquire one. Hearing aid use was associated with lower prevalence of probable dementia. CONCLUSION: The low number of hearing aid users indicates the difficulties elderly people face in acquiring them and/or that the health services face in effectively helping them to adapt. These findings may influence the quality of life of elderly with hearing impairment, given the association with probable dementia revealed by this study.

Linfomatosis intravascular cerebral como causa de demencia rápidamente progresiva: reporte de un caso / Cerebral intravascular lymphomatosis as cause of subacute dementia: report of a case

Cerebral Intravascular Lymphomatosis is a type of non Hodgkin Lymphoma, generally composed with B cells, its ocurrence is infrequent, clinically progressive and has a fatal course. Vascular damage is related with tumoral infiltration and small caliber occlusion, with results in multi infarcts. Neurological symptoms and signs are frequently the first clinical manifestation, which include sub acute encephalopathy, cognitive impairment, delirium, aphasia, hemipharesis, visual disturbances, paraplegia, paresthesia and cranial nerves involvement. MRI shows images of vasculitis from CNS. Cerebral Intravascular Lymphomatosis must be considered in differential diagnosis of rapid and subacute dementias, and clinical cases with small vessel recurrent multi infarct of unusual etiology. We present the clinical case of a patient with rapid progressive dementia and systemic disease manifestation. The CNS involvement was characterized as a subacute encephalopathy, with confusion and agitation, seizures, motor disturbances, bilateral plantar extensor reflexes and cerebellar signs. The clinical symptomatic course was progressive, with weight loss and fluctuant fever. The patient had a fatal course after he was treated with Methylprednisolone. Postmortem pathologic examination revealed a diffuse non Hodgkin lymphoma of B cells, intravascular variant, with brain compromise, cerebellum, suprarenal glands, pancreas, myocardium, thyroid gland, lung kidney and the lever...

La linfomatosis intravascular cerebral es un tipo de Linfoma no Hodgkin generalmente de células B, de presentación infrecuente, curso clínico progresivo y fatal. El daño vascular es producto de oclusión de vasos de pequeño calibre por infiltración tumoral, con resultado de múltiples infartos. Las manifestaciones neurológicas suelen ser la forma de presentación clínica inicial, caracterizadas por un amplio espectro que incluye encefalopatía subaguda, deterioro cognitivo, delirio, afasia, hemiparesia, trastornos visuales, paraplejia, parestesias y compromiso de pares craneanos. Los estudios de RNM evidencian alteraciones indistinguibles de las vasculitis del SNC. La linfomatosis intravascular debe considerarse en el diagnóstico diferencial de las demencias rápidamente progresivas y en los cuadros de multi infarto cerebral de pequeño vaso de etiología inusual y recurrente. Se presenta el caso de un paciente con demencia rápidamente progresiva, con manifestaciones neurológicas de deterioro cognitivo y enfermedad sistémica. El compromiso del SNC se expresó como encefalopatía subaguda con confusión, agitación, y crisis convulsivas, trastornos motores con reflejo cutáneo plantar extensor bilateral y compromiso cerebeloso, de curso clínico sintomático progresivo, con baja de peso y fiebre fluctuante. El paciente fue sometido a tratamiento con metilprednisolona a pesar del cual falleció. El estudio necrópsico demostró alteraciones por Linfoma no Hodgkin difuso de células B, variante intra vascular, con compromiso del cerebro, cerebelo, glándulas suprarrenales, páncreas, miocardio, tiroides, pulmón riñón e hígado...
