[Paradoxical lucidity and personal identity in patients with advanced dementia: change of paradigm?] / Lucidez paradójica e identidad personal en pacientes con demencia avanzada: ¿cambio de paradigma?

In this article we approach the concept of paradoxical lucidity (LP) (an unexpected, spontaneous, significant and relevant episode of communication or connection) in persons with advanced dementia. The existence of LP could change the paradigm of dementia as a degenerative, chronic, progressive and irreversible disease (where neuronal death plays the leading role), towards a model where functional deficits of neuronal networks acquire importance, which raises new potentially reversible therapeutic and rehabilitative possibilities. We analyze the ethical consequences that these episodes may have with respect to the implicated persons (patients, caregivers and professionals in charge of their care) and try to answer the following question: Do persons with advanced dementia continue to maintain their personal identity despite suffering cognitive impairment so severe?. The LP indicates that this is possible. In this work we make a transversal outline of the different concepts and theories of personal identity in these patients, from different areas of knowledge (philosophy, psychology, neuroscience).

[Tecuide. Telemonitoring of patients with dementia and their caregivers]. / Tecuide. Telemonitorización de pacientes con deterioro cognitivo y sus cuidadores.

INTRODUCTION: Given the growing increase in dementia, the need to control these patients, together with the rise of new technologies, makes a change in the current control system imperative. MATERIAL AND METHOD: We have carried out a single-center, clinical study with two groups, a control group of 72 patients/caregivers, who followed the usual controls in consultations, and another telematic group of 76 patients/caregivers, who followed the controls through of the Tecuide platform. The platform had a survey part to detect problems in patients and caregiver claudication, another training part and another chat for direct communication when the caregiver needed it and also served to respond when a problem was detected. RESULTS: After a year of monitoring with the platform we have obtained: a)in patients, reduce behavioral disorders and use of drugs, increase physical exercise and delay institutionalization (DS not found); b)in caregivers there is an improvement in satisfaction with respect to the control of patients with cognitive impairment, and c)in terms of resources, visits to emergency services and dementia consultations have decreased, although admissions to the psychogeriatric unit have increased. CONCLUSIONS: The use of Tecuide as a telematic tool in the control of patients with cognitive impairment does not seem to be inferior to the usual controls in consultations and improves caregiver satisfaction.

Early cortical atrophy in REM sleep behavior disorder. / Atrofia cortical precoz en el trastorno de conducta del sueño REM.

INTRODUCTION: The presence of cortical atrophy (focal or diffuse) prior to the development of symptoms of cognitive impairment could predict the earliest cases of neurodegenerative disease in patients with REM sleep behavior disorder (RSBD). We reviewed the usefulness of cranial CT and MRI as early markers of cortical atrophy in patients with RSBD at our center. PATIENTS AND METHODS: Retrospective observational descriptive analysis of patients diagnosed with RSBD from October 2012 to October 2022. All with cranial CT or MRI, evaluated by a neuroradiologist. RESULTS: 54 patients were included, 21 women (38.88%), 33 men (61.12%), mean age at diagnosis of RSBD: 69.04±12.625 years. Of the 54 patients, 44 (81.48%) had imaging tests consistent with their age, and 10 had atrophy greater than expected for their age. Of the 54 patients, 21 (38.88%) with a diagnosis of neurodegenerative disease, 33 (61.12%) persist as idiopathic, almost all with more than 5years of evolution (range of 1 to 10years of evolution without diagnosis). Of the 10 (18.52%) patients with greater atrophy, all were diagnosed with neurodegenerative disease (8 in 1year, 2 in 8years). CONCLUSIONS: Almost half of our series have developed a neurodegenerative disease in the first 10years of evolution. The majority of them presented global cortical atrophy measured by the GCA scale in the first year of diagnosis, without other neurological symptoms. Patients who did not show cortical atrophy at diagnosis have not yet developed the neurodegenerative disease in 10years of evolution. In our experience, the absence of cortical atrophy on cranial MRI or CT (measured by scales such as GCA) at the diagnosis of RSBD seems to predict slower progression cases. These data should be corroborated with larger series.

Asociación entre periodontitis, enfermedad cerebrovascular y demencia. Informe científico del Grupo de Trabajo de la Sociedad Española de Periodoncia y la Sociedad Española de Neurología / The association between periodontitis, cerebrovascular disease, and dementia. Scientific report of the Working Group of the Spanish Society of Periodontology and the Spanish Society of Neurology

Objetivo: Revisar la evidencia científica disponible sobre la relación entre la periodontitis y las enfermedades neurológicas, en particular la enfermedad cerebrovascular y la demencia. Además, se facilitan una serie de recomendaciones en relación con la prevención y el manejo de la periodontitis y estas enfermedades neurológicas desde las consultas dentales y las unidades de neurología. Desarrollo: Se realizó una búsqueda bibliográfica sin restricción en cuanto al diseño del estudio para identificar aquellos artículos más relevantes sobre la asociación entre periodontitis, enfermedad cerebrovascular y demencia desde un punto de vista epidemiológico, de intervención, así como de mecanismos biológicos involucrados en estas relaciones, y así responder a diferentes preguntas planteadas por los miembros del Grupo de Trabajo SEPA-SEN. Conclusiones: La periodontitis aumenta el riesgo de ictus isquémico y demencia de tipo Alzheimer. Bacteriemias recurrentes con aumento de un estado inflamatorio sistémico de bajo grado parecen ser posibles mecanismos biológicos que explicarían esta asociación. Una evidencia limitada apunta a que diferentes intervenciones de salud oral pueden reducir el riesgo futuro de padecer enfermedad cerebrovascular y demencia.(AU)

Objective: This article reviews the scientific evidence on the relationship between periodontitis and neurological disease, and particularly cerebrovascular disease and dementia. We also issue a series of recommendations regarding the prevention and management of periodontitis and these neurological diseases at dental clinics and neurology units. Development: In response to a series of questions proposed by the SEPA-SEN Working Group, a literature search was performed, with no restrictions on study design, to identify the most relevant articles on the association between periodontitis and cerebrovascular disease and dementia from the perspectives of epidemiology, treatment, and the biological mechanisms involved in these associations. Conclusions: Periodontitis increases the risk of ischaemic stroke and Alzheimer dementia. Recurrent bacterial infections and increased low-grade systemic inflammation seem to be possible biological mechanisms underlying this association. Limited evidence suggests that various oral health interventions can reduce the future risk of cerebrovascular disease and dementia.(AU)

Uso de antipsicóticos en los pacientes con demencia en España: comparación con la prescripción de los inhibidores de la acetilcolinesterasa y de la memantina, y análisis de las asociaciones / Use of antipsychotics in patients with dementia in Spain: Comparison with prescription of acetylcholinesterase inhibitors and memantine and analysis of associations

Objetivo: Se ha analizado la prevalencia de antipsicóticos, inhibidores de la acetilcolinesterasa (IACE) y memantina en pacientes con demencia en España y la influencia de estas asociaciones en su prescripción. Método: Estudio descriptivo, retrospectivo y transversal de la base BIFAP de 2017 en los mayores de 65 años con demencia. Se recogieron las prescripciones de antipsicóticos, los IACE y la memantina. Para los antipsicóticos también se recogieron, la duración del tratamiento y el tiempo desde el diagnóstico de demencia, al de prescripción. Resultados: Se recuperaron 1.327.792 sujetos, 89.464 (6,73%) con demencia. El 31,76% tuvieron prescritos antipsicóticos; los más frecuentes: quetiapina (58,47%), risperidona (21%) y haloperidol (19,34%). Las prescripciones de IACE y memantina fueron más frecuentes en los menores de 84 años y las de antipsicóticos en los mayores de 85 años (p<0,001). Los antipsicóticos se mantuvieron una media de 1.174,5 días. En el 26,4% de los casos se prescribieron aislados, OR: 0,61 (IC 95%: 0,59-0,62), en el 35,85% asociados a IACE, OR: 1,26 (IC 95%: 1,22-1,30) y en el 42,4% a memantina, OR: 1,69 (IC 95%: 1,62-1,78); p<0,000). Desde el diagnóstico de demencia transcurrieron de 461 días (±1.576,5) cuando se prescribieron aislados; 651 días (±1.574,25) asociados a IACE y 1.224 (±1.779) a memantina. Conclusiones: Una tercera parte de los pacientes con demencia tuvieron prescritos antipsicóticos, mayoritariamente atípicos, más frecuentemente en los mayores de 85 años y durante periodos prolongados. La prescripción de IACE y memantina se asoció al incremento del riesgo de uso de antipsicóticos, pero paradójicamente, a la prolongación del tiempo hasta su prescripción.(AU)

ObjectiveWe have analyzed the prevalence of antipsychotics in patients with dementia in Spain, their age distribution and the influence of treatment with IACEs and memantine on their prescription. Method: Descriptive, retrospective and cross-sectional study of the 2017 BIFAP database in over 65 years of age with dementia. Prescriptions of antipsychotics, IACEs and memantine were collected. For antipsychotics were also collected, the duration of treatment and time from dementia diagnosis to prescription. Results: A total of 1,327,792 subjects were retrieved, 89,464 (6.73%) with dementia. Antipsychotics were prescribed in 31.76%; by frequency: quetiapine (58.47%), risperidone (21%) and haloperidol (19.34%). Prescriptions of IACEs and memantine were clustered in those younger than 84 years and antipsychotics in those older than 85 (P<.001). Antipsychotics were maintained for a mean of 1174.5 days. In 26.4% of cases they were prescribed alone, OR 0.61 (95% CI: 0.59-0.62), in 35.85% associated with IACEs, OR 1.26 (95% CI: 1.22-1.30) and in 42.4% with memantine, OR 1.69 (95% CI: 1.62-1.78) (P<.000). From the diagnosis of dementia, 461 days (±1576.5) elapsed when isolated drugs were prescribed; 651 days (±1574.25) associated with IACEs and 1224 (±1779) with memantine. Conclusions: One third of patients with dementia were prescribed antipsychotics, mostly atypical, more frequently in those older than 85 years and for prolonged periods. IACEs and memantine were associated with the risk of antipsychotic prescription, but paradoxically, with prolonged time to onset.(AU)

Medical and forensic aspects of performing a remote interrogation of persons with disabilities / Aspectos médicos y forenses de la realización de un interrogatorio a distancia a personas con discapacidad / Aspectos médicos e forenses da realização de um interrogatório remoto de pessoas com deficiências

The purpose of the study is to develop new proposals for improving criminal procedural legislation in the field of conducting remote investigative actions with disabled persons, taking into account their physiological and functional characteristics. Research material and methods: This study is based on an analysis of the norms regarding the criminal procedural legislation of the Republic of Kazakhstan and a number of foreign states that regulate the procedure for conducting remote investigative actions - as well as scientific publications on the research topic in the field of psychology and medicine. An integrated approach involves considering the studied phenomena of communication during an investigative action as a set of interconnected and interdependent elements, i.e., consideration of the issue from the medical, psychological and legal points of view. Situational and systemic types of analysis, complex sociological analysis, diagnostics and forecasting investigative situation were also used. Methods of analysis and synthesis, induction, deduction, methods of qualitative and quantitative analysis were employed to clarify the legal essence of the studied phenomenon. Findings: practical recommendations aimed at improving and developing the performance of remote investigative actions involving persons with disabilities (further ­ FWDs) y creating optimal conditions for the transfer of verbal, medical, and psychological information, as well as technical and forensic support for conducting RIAs. The following conclusions were made: in order to improve the current legislation, it is advisable to consider the issue of developing and including a special norm in the legislation, taking into account the characteristics of the communicative competencies of persons with disabilities. This norm regulates the procedure for conducting investigative actions involving the mute, deaf, blind and other persons with disabilities.

El objetivo del estudio es elaborar nuevas propuestas de mejora de la legislación procesal penal en el ámbito de la realización de actuaciones de investigación a distancia con personas con discapacidad, teniendo en cuenta sus características fisiológicas y funcionales. Material y métodos de investigación: Este estudio se basa en un análisis de las normas relativas a la legislación procesal penal de la República de Kazajstán y de una serie de Estados extranjeros que regulan el procedimiento para llevar a cabo acciones de investigación a distancia -, así como publicaciones científicas sobre el tema de investigación en el campo de la psicología y la medicina. Un enfoque integrado implica considerar los fenómenos estudiados de comunicación durante una acción de investigación como un conjunto de elementos interconectados e interdependientes, es decir, considerar la cuestión desde los puntos de vista médico, psicológico y jurídico. También se utilizaron los tipos de análisis situacional y sistémico, el análisis sociológico complejo, el diagnóstico y la previsión de la situación de investigación. Se emplearon métodos de análisis y síntesis, inducción, deducción, métodos de análisis cualitativo y cuantitativo para aclarar la esencia jurídica del fenómeno estudiado. Conclusiones: recomendaciones prácticas destinadas a mejorar y desarrollar la realización de acciones de investigación a distancia en las que participen personas con discapacidad (en adelante - RIA) y crear condiciones óptimas para la transferencia de información verbal, médica y psicológica, así como apoyo técnico y forense para la realización de las RIA. Se llegó a las siguientes conclusiones:con el fin de mejorar la legislación actual, es aconsejable considerar la cuestión de desarrollar e incluir una norma especial en la legislación, teniendo en cuenta las características de las competencias comunicativas de las personas con discapacidad. Esta norma regula el procedimiento para llevar a cabo acciones de investigación en las que estén implicadas personas mudas, sordas, ciegas y otras personas con discapacidad.

O objetivo do estudo é desenvolver novas propostas para aprimorar a legislação processual penal no campo da realização de ações investigativas remotas com pessoas com deficiência, levando em conta suas características fisiológicas e funcionais. Material e métodos de pesquisa: Este estudo baseia-se em uma análise das normas relativas à legislação processual penal da República do Cazaquistão e de vários países estrangeiros que regulamentam o procedimento para a realização de ações investigativas remotas, bem como em publicações científicas sobre o tópico de pesquisa no campo da psicologia e da medicina. Uma abordagem integrada envolve a consideração dos fenômenos estudados de comunicação durante uma ação investigativa como um conjunto de elementos interconectados e interdependentes, ou seja, a consideração da questão dos pontos de vista médico, psicológico e jurídico. Também foram usados tipos de análise situacional e sistêmica, análise sociológica complexa, diagnóstico e previsão da situação investigativa. Métodos de análise e síntese, indução, dedução, métodos de análise qualitativa e quantitativa foram empregados para esclarecer a essência legal do fenômeno estudado. Resultados: recomendações práticas com o objetivo de aprimorar e desenvolver o desempenho de ações investigativas remotas envolvendo pessoas com deficiência (mais adiante - FWDs), criando condições ideais para a transferência de informações verbais, médicas e psicológicas, bem como suporte técnico e forense para a realização de RIAs. Foram feitas as seguintes conclusões: para aprimorar a legislação atual, é aconselhável considerar a questão do desenvolvimento e da inclusão de uma norma especial na legislação, levando em conta as características das competências comunicativas das pessoas com deficiência. Essa norma regulamenta o procedimento para conduzir ações investigativas envolvendo pessoas mudas, surdas, cegas e outras pessoas com deficiência.

Posttraumatic stress disorder in people with dementia: study protocol.

Background: Posttraumatic stress disorder (PTSD) is considered an independent risk factor for dementia. Despite the (clinical) evidence that PTSD is associated with neuropsychiatric symptoms in people with dementia, studies on its prevalence and clinical manifestation are limited, and their quality is affected by the lack of a structured method to diagnose PTSD in this population. The primary aim of the current study is to validate the 'TRAuma and DEmentia' interview as a diagnostic tool for PTSD in people with dementia and to test feasibility of EMDR treatment for people with PTSD and dementia.Methods: This prospective multi-centre study is divided into two parts. In study A, 90 participants with dementia will be included to test the criterion validity, inter-rater reliability and feasibility of the 'TRAuma and DEmentia' interview. In study B, 29 participants with dementia and PTSD will receive eye movement desensitisation and reprocessing therapy by a trained psychologist, and 29 participants with dementia and PTSD will be placed on the waiting list control group.Conclusion: This study aims to improve the diagnostic process of PTSD and to assess the effects of eye movement desensitisation and reprocessing treatment in people with dementia living in Dutch care facilities.Trial registration: NL70479.068.20 / METC 20-063 / OSF registration: https://doi.org/10.17605/OSF.IO/AKW4F.

La depresión como factor de riesgo de la demencia: fisiopatología y modelos preclínicos de estudio / Depression as a risk factor for dementia: Pathophysiology and preclinical study models

El aumento de la esperanza de vida ha llevado a un incremento en la incidencia de enfermedades crónicas como la demencia. Tratar los factores de riesgo de la demencia, como la depresión, podría reducir su incidencia. Sin embargo, el tratamiento con antidepresivos no ha sido eficaz en el manejo de este síntoma, lo que aumenta el riesgo de demencia en el futuro. Es fundamental investigar las causas y el tratamiento de la depresión, y el uso de modelos animales es importante en este sentido. Este estudio busca analizar la relación entre la depresión y el riesgo de desarrollar demencia, así como los modelos preclínicos más relevantes para estudiar la depresión en roedores. (AU)

The increase in life expectancy has led to a rise in the incidence of chronic diseases, such as dementia. Treating the risk factors of dementia, such as depression, could help reduce its occurrence. However, antidepressant treatment has not proven effective in managing this symptom, thereby increasing the risk of dementia in the future. It is essential to investigate the causes and treatment of depression, and in this regard, the use of animal models is of great significance. This study aims to analyze the evidence supporting the relationship between depression and the risk of developing dementia, while also providing an update on the most relevant preclinical models for studying depression in rodents.

Association between psoriasis and dementia: A systematic review / Asociación entre psoriasis y el desarrollo de demencia: una revisión sistemática

Introduction Risk factors for dementia include genetic factors, aging, environmental factors, certain diseases, and unhealthy lifestyle; most types of dementia share a common chronic systemic inflammatory phenotype. Psoriasis is also considered to be a chronic systemic inflammatory disease. It has been suggested that psoriasis may also contribute to the risk of dementia. The aim of this study was to systematically review the literature on the association between psoriasis and dementia. Development Articles were selected according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. We searched the PubMed and Web of Science databases to identify articles published in peer-reviewed journals and studying the association between psoriasis and dementia. Studies meeting the inclusion criteria were reviewed. We used the Newcastle–Ottawa Scale to assess the quality of each study. After applying the inclusion and exclusion criteria, we included 8 studies for review, 3 of which were found to present a higher risk of bias. Six of the 8 studies supported the hypothesis that prior diagnosis of psoriasis increases the risk of dementia; one study including only a few cases reported that psoriasis decreased the risk of dementia, and one study including relatively young patients found no significant association between psoriasis and the risk of dementia. Conclusion Most studies included in this review supported the hypothesis that psoriasis constitutes a risk factor for dementia. However, well-designed stratified cohort studies assessing both psoriasis severity and treatment status are still required to determine the real effect of psoriasis on the risk of dementia and its subtypes.

Trends in Parkinson's mortality in Mexico 2000-2020.

OBJECTIVE: To describe the recent trends in Parkinson's disease mortality in Mexico during 2000-2020. METHOD: The adjusted mortality rate per 100,000 inhabitants was calculated using the direct method and the world standard population. Trend analysis was performed with the Joinpoint software. RESULTS: The average mortality rate was 1.26/100,000 inhabitants (SD: 0.09), and males showed higher mortality than females (M/F ratio=1.60). Older individuals ≥70 years old showed higher mortality rates than the rest of the age groups. During the period of study, a significant increase in mortality was observed from 2000 to 2005, while from 2005 to 2020 no significant trend was observed in all the studied groups. CONCLUSIONS: In Mexico, males and older individuals showed the highest mortality rates. The socioeconomic regions with high levels of wellness showed the highest mortality rates levels. Parkinson's mortality rate has remained constant since 2005 in Mexico.

The association between periodontitis and cerebrovascular disease, and dementia. Scientific report of the working group of the Spanish Society of Periodontology and the Spanish Society of Neurology.

OBJECTIVE: This article reviews the scientific evidence on the relationship between periodontitis and neurological disease, and particularly cerebrovascular disease and dementia. We also issue a series of recommendations regarding the prevention and management of periodontitis and these neurological diseases at dental clinics and neurology units. DEVELOPMENT: In response to a series of questions proposed by the SEPA-SEN working group, a literature search was performed, with no restrictions on study design, to identify the most relevant articles on the association between periodontitis and cerebrovascular disease and dementia from the perspectives of epidemiology, treatment, and the biological mechanisms involved in these associations. CONCLUSIONS: Periodontitis increases the risk of ischaemic stroke and Alzheimer dementia. Recurrent bacterial infections and increased low-grade systemic inflammation seem to be possible biological mechanisms underlying this association. Limited evidence suggests that various oral health interventions can reduce the future risk of cerebrovascular disease and dementia.

Miastenia gravis y enfermedad de Alzheimer: una asociación a estudio / Association between myasthenia gravis and Alzheimer’s disease

Introducción La miastenia gravis (MG) y la enfermedad de Alzheimer (EA) son dos de las enfermedades neurológicas en cuya fisiopatología interviene la acetilcolina en distintos niveles. En la primera, la alteración de este neurotransmisor se produce en la unión neuromuscular, y en la segunda, en el sistema nervioso central. Objetivo Analizar la posible relación entre dichas patologías estudiando la prevalencia y la odds ratio de la EA dentro de los pacientes diagnosticados de MG con respecto a la prevalencia de EA en la población general. Pacientes y métodos Se han examinado datos de las historias clínicas electrónicas del sistema de salud de Castilla-La Mancha utilizando el procesamiento de lenguaje natural a través de la plataforma clínica de inteligencia artificial Savana Manager?. Resultados Se ha identificado a 970.503 pacientes mayores de 60 años, de los que 1.028 tenían diagnóstico de MG. La proporción de pacientes con diagnóstico de EA dentro de este grupo (4,28%) es mayor que en el resto de la población (2,82%; p = 0,0047), con una odds ratio de 1,54 (intervalo de confianza al 95%: 1,13-2,08; p = 0,0051), sin que se encuentren diferencias significativas en el análisis bivariante del resto de los factores de riesgo para EA más importantes conocidos hasta ahora. Conclusiones Nuestros resultados sugieren que podría existir un aumento de la prevalencia de EA en pacientes con MG. (AU)

INTRODUCTION Myasthenia gravis (MG) and Alzheimer’s disease (AD) are two of the most important diseases where the dysregulation of acetylcholine activity plays a crucial role. In the first, this dysregulation happens at the level of the neu­romuscular junction and in the second, in the central nervous system (CNS). AIM To analyze the possible relationship between these two pathologies, analyzing the prevalence and the odds ratio of AD within patients previously diagnosed with MG. We will compare these data with respect to the prevalence of AD in the general population. PATIENTS AND METHODS We examined the data obtained by the electronic medical records of patients in the health care system of Castilla La Mancha using the Natural Language Process provided by a clinical platform of artificial intelligence known as the Savana Manager?. RESULTS We identified 970,503 patients over the age of 60 years, of which 1,028 were diagnosed with MG. The proportion of the patients diagnosed with AD within this group (4.28%) was greater than the rest of the population (2.82%) (p = 0,0047) with an odds ratio of 1.54 (confidence interval at 95% 1.13-2.08; p = 0.0051) without finding significant differences in the bivariate analysis for the rest of the most important actual known risk factors for AD. CONCLUSION. Our results suggest that there might be an increase in the prevalence of AD in patients previously diagnosed with MG. (AU)

[Use of antipsychotics in patients with dementia in Spain: Comparison with prescription of acetylcholinesterase inhibitors and memantine and analysis of associations]. / Uso de antipsicóticos en los pacientes con demencia en España: comparación con la prescripción de los inhibidores de la acetilcolinesterasa y de la memantina, y análisis de las asociaciones.

OBJECTIVE: We have analyzed the prevalence of antipsychotics in patients with dementia in Spain, their age distribution and the influence of treatment with IACEs and memantine on their prescription. METHOD: Descriptive, retrospective and cross-sectional study of the 2017 BIFAP database in over 65 years of age with dementia. Prescriptions of antipsychotics, IACEs and memantine were collected. For antipsychotics were also collected, the duration of treatment and time from dementia diagnosis to prescription. RESULTS: A total of 1,327,792 subjects were retrieved, 89,464 (6.73%) with dementia. Antipsychotics were prescribed in 31.76%; by frequency: quetiapine (58.47%), risperidone (21%) and haloperidol (19.34%). Prescriptions of IACEs and memantine were clustered in those younger than 84 years and antipsychotics in those older than 85 (P<.001). Antipsychotics were maintained for a mean of 1174.5 days. In 26.4% of cases they were prescribed alone, OR 0.61 (95% CI: 0.59-0.62), in 35.85% associated with IACEs, OR 1.26 (95% CI: 1.22-1.30) and in 42.4% with memantine, OR 1.69 (95% CI: 1.62-1.78) (P<.000). From the diagnosis of dementia, 461 days (±1576.5) elapsed when isolated drugs were prescribed; 651 days (±1574.25) associated with IACEs and 1224 (±1779) with memantine. CONCLUSIONS: One third of patients with dementia were prescribed antipsychotics, mostly atypical, more frequently in those older than 85 years and for prolonged periods. IACEs and memantine were associated with the risk of antipsychotic prescription, but paradoxically, with prolonged time to onset.

Dementia prevalence among hospitalized older patients: a multicenter study in Iran / Prevalência de demência entre pacientes idosos hospitalizados: um estudo multicêntrico no Irã

ABSTRACT Dementia poses a significant societal and health challenge in the 21st century, with many hospitalized patients experiencing dementia without a documented diagnosis. Objective: To evaluate the prevalence of dementia and its associated risk factors among older patients admitted to hospitals. Methods: The study included older patients (≥ 60 years) admitted to medical departments of a general hospital in three major Iranian cities. Researchers utilized the Activities of Daily Living-Instrumental Activities of Daily Living (ADL-IADL) scale, the Geriatric Depression Scale (GDS), the Mini-Cog test, the 4 A's test (4AT), and the Abbreviated Mental Test Score (AMTS). Among the 420 recruited older inpatients, 228 (54.3%) were female. Results: The mean age of participants was 71.39 years (standard deviation ±7.95), with 30.7% diagnosed with major neurocognitive disorder (dementia). The likelihood of dementia exhibited statistically significant correlations with gender, age, number of children, and occupation. Conclusions: Screening older individuals for cognitive impairment upon hospital admission holds the potential to prevent adverse outcomes and enhance the quality of treatment for patients concurrently dealing with dementia.

RESUMO A demência representa um grande desafio social e de saúde no século 21, com muitos pacientes hospitalizados sofrendo de demência sem um diagnóstico documentado. Objetivo: Avaliar a prevalência de demência e seus fatores de risco associados entre pacientes idosos hospitalizados. Métodos: O estudo incluiu pacientes idosos (≥ 60 anos) internados em um hospital geral em três grandes cidades iranianas. Os pesquisadores utilizaram a escala de Atividades da Vida Diária-Atividades Instrumentais da Vida Diária (Activities of Daily Living-Instrumental Activities of Daily Living - ADL-IADL), a Escala de Depressão Geriátrica, o teste Mini-Cog, o teste dos 4 As (4AT) e o Pontuação do Teste Mental Abreviado (Abbreviated Mental Test Score - AMTS). Dos 420 idosos selecionados, 228 (54,3%) eram do sexo feminino. Resultados: A média de idade dos participantes foi de 71,39 anos (desvio padrão ±7,95), sendo 30,7% diagnosticados com transtorno neurocognitivo maior (demência). A probabilidade de demência apresentou correlações estatisticamente significativas com sexo, idade, número de filhos e ocupação. Conclusões: A triagem de idosos para comprometimento cognitivo na admissão hospitalar tem o potencial de prevenir resultados adversos e melhorar a qualidade do tratamento para pacientes que lidam simultaneamente com demência.

Soledad en cuidadores informales de personas con demencia durante la pandemia de COVID-19 / Loneliness in informal caregivers of people with dementia during the COVID-19 pandemic

ANTECEDENTES Y OBJETIVO: La soledad es un factor de riesgo para el desarrollo de enfermedades físicas y mentales, causando disminución en la calidad de vida y un aumento de la mortalidad. El objetivo de este artículo fue determinar los factores predictores de soledad en personas cuidadoras informales de personas con demencia dentro de un contexto de crisis como fue la pandemia por COVID-19 con el fin de identificar e intervenir en dichos factores desde la atención primaria de salud. DISEÑO Y METODOLOGÍA: Este es un estudio cuantitativo de carácter transversal para el cual se realizó un muestreo de conveniencia no probabilístico. Ciento noventa y cinco personas cuidadores informales, por medio de una encuesta en línea, respondieron preguntas sociodemográficas y clínicas sobre ellos mismos (soledad, síntomas ansiosos y depresivos, actividades físicas y mentales, sobrecarga y apoyo psicosocial) y sobre la persona con demencia (cambios en la memoria y en los síntomas conductuales y psicológicos). Los datos fueron recolectados durante 6 meses y se hicieron análisis descriptivos, de correlación y de regresión. RESULTADOS: La baja escolaridad, disminución del ingreso económico, no mantener durante la pandemia las actividades físicas y mentales y la sobrecarga en el cuidador se relacionaron significativamente con mayor soledad, mientras que los factores predictores de la misma fueron la presencia de sintomatología ansiosa depresiva, la baja percepción de apoyo psicosocial y la convivencia de la persona cuidadora con la persona con demencia. CONCLUSIÓN: El riesgo de desarrollar soledad en los cuidadores informales de personas con demencia es alto. Los profesionales de enfermería, particularmente en atención primaria, deben estar alertas a identificar a aquellos cuidadores que conviven con la persona con demencia, que presentan síntomas ansiosos y depresivos y que reportan una baja percepción de apoyo psicosocial dado que son más vulnerables de experimentar soledad percibida.

BACKGROUND AND OBJECTIVE: Loneliness is a risk factor for the development of physical and mental illness, causing decreased quality of life and increased mortality. The aim of this article was to recognise predictors of loneliness in informal caregivers of people with dementia in the context of a crisis such as the COVID-19 pandemic. DESIGN AND METHODOLOGY: 195 informal caregivers, through an online survey, answered sociodemographic and clinical questions about themselves (loneliness, anxious and depressive symptoms, physical and mental activities, overload and psychosocial support) and about the person with dementia (changes in memory and behavioural and psychological symptoms). RESULTS: Low schooling, decreased income, failure to maintain physical and mental activities during the pandemic and caregiver overload were significantly related to increased loneliness, while predictors of loneliness were the presence of depressive anxiety symptoms, low perception of psychosocial support and the caregiver living with the person with dementia. CONCLUSION: The risk of developing loneliness in caregivers of people with dementia is high. Nursing professionals, particularly in primary care, should be on the alert for those caregivers within this group who live with the person with dementia, who present anxious and depressive symptoms and who report a low perception of psychosocial support, as they are more vulnerable to experiencing perceived loneliness.

Identification of Neuropsychiatric Symptoms in Preclinical and Prodromal Stages in Dementias: Development of a Screening Test for Mild Behavioral Impairment / Identificación de los Síntomas Neuropsiquiátricos en Fases Preclínicas y Prodrómicas en Demencias: Desarrollo de un Test de Cribado para el Deterioro Conductual Leve

Background: Neuropsychiatric symptoms (NPS) are a psychopathological dimension of neurodegenerative diseases, consisting of personality changes, behavioral disorders, and alterations in basic functions such as appetite or sleep, among others. The aim of this study was the construction and validation of a screening test to identify these NPS associated with neurodegenerative pathologies in preclinical and prodromal stages, based on the ISTAART criteria for Mild Behavioral Impairment (MBI). Method: The sample consisted of 206 subjects over 55 years old (117 cognitively healthy, 89 with Mild Cognitive Impairment). 69% were women, the mean age was 77 years (SD = 10.58). Results: The new scale consists of 19 items and exhibited a one-dimensional structure. Confidence was excellent (α = .94 and Ω = .97) and there was evidence of convergent validity with the MBI-C test (r = .88) and the NPI-Q (r = .82). In addition, the scale demonstrated good sensitivity (.88) and specificity (.80). Conclusions: The scale allows evaluation of NPS in DCoL. It exhibits good psychometric properties and makes a useful tool in early diagnosis of neurodegenerative pathologies.(AU)

Antecedentes: Los síntomas neuropsiquiátricos (SNP) constituyen una dimensión psicopatológica de las enfermedades neurodegenerativas conformada por cambios en la personalidad, trastornos conductuales o alteraciones en funciones básicas como, entre otras, el apetito o el sueño. El objetivo de este estudio es la construcción y validación de un test de cribado para la identificación de estos SNP asociados a patologías neurodegenerativas en etapas preclínicas y prodrómicas y basado en los criterios ISTAART para el Deterioro Conductual Leve (DCoL). Método: Se empleó una muestra de 206 sujetos mayores de 55 años (117 cognitivamente sanos y 89 con Deterioro Cognitivo Leve) siendo el 69% mujeres, con una media de edad de 77 años (DT = 10,58). Resultados: La nueva escala desarrollada consta de 19 items y muestra una estructura unidimensional. La fiabilidad fue excelente (α = .94 y Ω = .97) y se observaron evidencias de validez convergente con el test MBI-C con una correlación de .88 y la NPI-Q con .82. Además, muestra una buena sensibilidad de .88 y especificidad de .80. Conclusiones: La escala desarrollada permite evaluar los SNP en el DCoL mostrando buenas propiedades psicométricas y constituyendo una herramienta muy útil en el diagnóstico precoz de las patologías neurodegenerativas.(AU)
