The Weight of Bariatric Surgery: Wernicke-Korsakoff Syndrome after Vertical Sleeve Gastrectomy-A Case Series.

In this case series, the simultaneous occurrence of Wernicke's encephalopathy (WE) and dry beriberi was reported in three patients who underwent vertical sleeve gastrectomy (VSG) between May 2021 and May 2023. All patients were obese women who underwent vertical sleeve gastrectomy (VSG) without immediate postoperative complications, but two weeks later, hyperemesis and subsequent encephalopathy with ocular movement abnormalities and weakness were observed over the following thirty days. Patients were referred to neurology, where due to the high suspicion of WE, thiamine replacement therapy was initiated; meanwhile, diagnostic neuroimaging and blood tests were conducted. Neurological and psychiatric evaluations and neuroconduction studies were performed to assess the clinical evolution and present sequelae. One year after diagnosis, all patients exhibited affective and behavioral sequelae, anterograde memory impairment, and executive functioning deficits. Two patients met the criteria for Korsakoff syndrome. Additionally, peripheral nervous system sequelae were observed, with all patients presenting with sensorimotor polyneuropathy. In conclusion, Wernicke's encephalopathy requires a high diagnostic suspicion for timely intervention and prevention of irreversible sequelae, which can be devastating. Therefore, raising awareness among medical professionals regarding the significance of this disease is essential.

Serious Games to Improve Attention in Boys and Girls with Attention Deficit Hyperactivity Disorder (ADHD): A Pilot Study

Background: The objective of this study was to test a treatment program in Serious Games (SG) format to improve attention in children from Catalonia, Spain, with Attention Deficit Hyperactivity Disorder (ADHD). The activities adapted to the SG format consisted of (1) stimulus selection, (2) mark equal drawings, (3) eight differences, (4) hidden figures, (5) compare texts, (6) compare measures and shapes, (7) put model keys, (8) labyrinths and (9) memorization of drawings. Method: A pretest-posttest design was used with a cohort of 30 children between 8 and 10 years old diagnosed with ADHD, with 20% girls (n = 6) and 80% boys (n = 24) with a mean age of 9.4 years (SD = 0.63; range of 8 to 10 years). Four schools and a clinical center from Catalonia, Spain participated in the sample composition. Half of the sample participated in an attention improvement program for nine sessions of 30-45 minutes each in Serious Games format. They were presented with a series of game challenges with various virtual scenarios through a monitor. The other half did the same attention improvement program in pencil and paper format. Results: The children in the Serious Games group progressed and improved more during treatment, as shown by the average number of errors of commission (p =.02) than those in the pencil and paper group. Both groups also improved in the total score and concentration scale of the D2 test (p < .001). Conclusions: Attentional training through programs in Serious Games format seems to have a more significant effect on commission errors than attentional training in pencil and paper format.

Antecedentes: El objetivo del presente estudio ha sido poner a prueba un programa de tratamiento en formato Serious Games (SG) para mejorar la atención en niños de Cataluña, España, con Trastorno por Déficit de Atención/Hiperactividad (TDAH). Las actividades adaptadas al formato SG consistieron en (1) selección de estímulos, (2) marcar dibujos iguales, (3) ocho diferencias, (4) figuras ocultas, (5) comparar textos, (6) comparar medidas y formas, (7) poner llaves modelo, (8) laberintos y (9) memorización de dibujos. Método: Se utilizó un diseño pretest-postest con una cohorte de 30 niños entre 8 y 10 años con diagnóstico de TDAH, con un 20% de niñas (n = 6) y un 80% de niños (n = 24) con una edad media de 9.4 años (DE = 0.63; rango de 8 a 10 años). La mitad de la muestra participó en un programa de mejora de la atención durante 9 sesiones de entre 30-45 minutos cada una en formato de Serious Games. Se les presentó una serie de desafios de juego con varios escenarios virtuales a través de un monitor. La otra mitad de la muestra hizo el mismo programa de mejora de la atención, pero en formato lápiz y papel. Resultados: Los niños del grupo de Serious Games progresaron y mejoraron más durante el tratamiento, como lo demuestra el promedio de errores de comisión (p = .02), en comparación con los niños del grupo de lápiz y papel. Ambos grupos también mejoraron en la puntuación total y en la escala de concentración de la prueba D2 (ambos p < .001). Conclusiones: El entrenamiento atencional a través de programas en formato Serious Games parece tener un mayor efecto que el entrenamiento atencional en formato lápiz y papel sobre los errores de comisión.

Major depression associated with a levonorgestrel-releasing intrauterine system mimicking frontotemporal dementia: a case report.

This case illustrates the adverse cognitive and affective effects associated with the use of an intrauterine hormonal contraceptive, which could be confused with symptoms of early onset dementia. We present a case of a 42-year-old woman diagnosed with seronegative spondyloarthropathy who subsequently developed anxiety and depressive symptoms after the implantation of a Levonorgestrel-Releasing Intrauterine System (LNG-IUS). Three years later, she began to experience memory and attentional failures, refractory pain, and severe depression. The progression of psychiatric symptoms led to a diagnosis of bipolar affective disorder and treatment with antidepressants and anxiolytics. Due to cognitive and psychiatric symptoms, autoimmune encephalitis was considered, but no improvement was shown with treatment. Early onset dementia was suspected, and a brain PET scan revealed frontal lobe hypometabolism. An adverse effect of LNG-IUS was considered; after its removal, mood and cognitive function improvements were observed. This case report emphasizes the importance of considering organic causes of unexplained psychiatric manifestations and highlights the potential impact of hormonal interventions on mental health.

Determinación de intersecciones probabilísticas relacionadas con daño cerebral adquirido a partir de la determinación de probabilidades a priori y a posteriori.

BACKGROUND: The acquired brain damage is a common neurological disorder. OBJECTIVE: Determine the probabilistic intersections of variables related to acquired brain damage from the determination of a priori and a posteriori probabilities. METHOD: Analytical retrospective study. A descriptive analysis was carried out, confidence intervals were calculated to obtain the mean and the proportion with α = 0.05 considering the age of the patient and the diagnosis. An analysis of probabilistic intersection, a priori and a posteriori probability was performed considering diagnosis, sex and age decade; finally, chi squared was calculated. RESULTS: 736 patients were analyzed. The most frequent diagnosis was language disorder. The patients diagnosed with memory disorder were the youngest and those diagnosed with degenerative cognitive disorder the oldest. The probability that a patient with sequelae due to acquired brain damage arrives at the hospital, at the language pathology service, to be diagnosed with a language disorder and that this patient is also a man is 29.06%. CONCLUSIONS: The high prevalence of short and long-term disability generated by acquired brain damage highlights the importance of an early and timely detection and diagnosis so that it favors prompt and efficient specialized care.

ANTECEDENTES: El daño cerebral adquirido es un trastorno neurológico común. OBJETIVO: Determinar las intersecciones probabilísticas de variables relacionadas con daño cerebral adquirido a partir de la determinación de probabilidades a priori y a posteriori. MÉTODO: Estudio retrospectivo analítico. Se realizó análisis descriptivo y se calcularon intervalos de confianza para la media y para la proporción con α = 0.05 considerando la edad del paciente y el diagnóstico. Se realizó análisis de intersección probabilística, probabilidad a priori y a posteriori considerando el diagnóstico, el sexo y la década de edad; por último, se utilizó la prueba χ2. RESULTADOS: Se analizaron 736 pacientes. El diagnóstico más frecuente fue el trastorno del lenguaje. Los pacientes diagnosticados con trastorno de memoria fueron los más jóvenes y los diagnosticados con trastorno cognitivo degenerativo los más longevos. La probabilidad de que llegue al hospital, al servicio de patología de lenguaje, un paciente con secuelas por daño cerebral adquirido, sea diagnosticado con trastorno del lenguaje y sea hombre es del 29.06%. CONCLUSIONES: La alta prevalencia de discapacidad a corto y largo plazo generada por el daño cerebral adquirido indica la importancia de la detección y el diagnóstico temprano y oportuno que favorezcan una pronta y eficiente atención especializada.

Hepatitis C Virus (HCV) Infection and Neurocognitive Impairment in Subjects with Mild Liver Disease.

Hepatitis C virus (HCV) infection is a leading cause of liver cirrhosis, hepatocellular carcinoma, and liver-related deaths. It is estimated that 40-74% of patients with hepatitis C will experience at least one extrahepatic manifestation within their lifetime. The finding of HCV-RNA sequences in post-mortem brain tissue raises the possibility that HCV infection may affect the central nervous system and be the source of subtle neuropsychological symptoms, even in non-cirrhotic. Our investigation aimed to evaluate whether asymptomatic, HCV-infected subjects showed cognitive dysfunctions. Twenty-eight untreated asymptomatic HCV subjects and 18 healthy controls were tested using three neuropsychological instruments in a random sequence: Symbol Digit Modalities Test (SDMT), Controlled Oral Word Association Test (COWAT), and Continuous Visual Attention Test (CVAT). We performed depression screening, liver fibrosis assessment, blood tests, genotyping, and HCV-RNA viral load. A MANCOVA and univariate ANCOVAS were performed to examine group differences (HCV vs. healthy controls) in four scores of the CVAT (omission errors, commission errors, reaction time-RT, and variability of RT-VRT), and the scores derived from the SDMT, and the COWAT. A discriminant analysis was performed to identify which test variables effectively discriminate HCV-infected subjects from healthy controls. There were no group differences in the scores of the COWAT, SDMT, and in two variables of the CVAT (omission and commission errors). In contrast, the performance of the HCV group was poorer than the controls in RT (p = 0.047) and VRT (p = 0.046). The discriminant analysis further indicated that the RT was the most reliable variable to discriminate the two groups with an accuracy of 71.7%. The higher RT exhibited by the HCV group may reflect deficits in the intrinsic-alertness attention subdomain. As the RT variable was found to be the best discriminator between HCV patients and controls, we suggest that intrinsic-alertness deficits in HCV patients may affect the stability of response times increasing VRT and leading to significant lapses in attention. In conclusion, HCV subjects with mild disease showed deficits in RT and intraindividual VRT as compared to healthy controls.

Perfil clínico neuropsicológico del deterioro cognitivo subtipo posible Alzheimer / Clinical and Neuropsychological Profile of Possible Alzheimer subtype neurocognitive disorder

Introducción: La enfermedad de Alzheimer se presenta con diferentes fenotipos neuropsicológicos y se considera que el deterioro de la memoria es su afectación más sobresaliente; no obstante, estudios recientes sugieren que los trastornos en las funciones ejecutivas pueden constituir marcadores muy tempranos de la enfermedad. Objetivos: Caracterizar los perfiles clínicos y neuropsicológicos que constituyen marcadores fenotípicos de los trastornos neurocognitivos subtipo posible Alzheimer. Métodos: Se realizó un estudio descriptivo y transversal de 39 enfermos con edades comprendidas entre 57-85 años, clasificados según los criterios del DSM-5, con deterioro cognitivo leve y mayor, catalogados desde el punto de vista etiológico en el subtipo posible Alzheimer. Se evaluaron múltiples dominios cognitivos (atención compleja, memoria y aprendizaje, funciones ejecutivas, lenguaje, funciones motoras y perceptuales) y se hizo una evaluación detallada de las funciones ejecutivas mediante un grupo de test neuropsicológicos específicos. Resultados: El análisis estadístico demostró que entre los dos grupos de estudio con deterioro cognitivo existen diferencias significativas en cuanto al nivel de funcionamiento cognitivo en todos los dominios explorados, excepto en la percepción y funciones motoras. Así mismo, los resultados demostraron que el nivel de rendimiento para cada función evaluada dentro del dominio de las funciones ejecutivas es significativamente diferente entre ambos grupos con deterioro cognitivo, excepto para la orientación espacial. Conclusiones: El perfil neuropsicológico del deterioro cognitivo subtipo posible Alzheimer se caracterizó por una afectación en múltiples dominios, con predominio de la disfunción ejecutiva focalizada en las áreas de la flexibilidad mental e inhibición de automatismos.

Introduction: Alzheimer disease is presented with different neuropsychological phenotypes and it is considered that the memory disorder is its most important one; however, recent studies suggest that the dysfunctions in the executive functions can constitute very early markers of the disease. Objectives: To characterize the clinical and neuropsychological profiles that constitutes phenotypical markers of the neurocognitive disorders possible Alzheimer subtype. Methods: A descriptive and cross-sectional study of 39 sick persons with ages between 57-85 years, classified according to the DSM-5 criteria, with cognitive mild and major disorder, classified from the etiological point of view in the possible Alzheimer subtype was carried out. Multiple cognitive domains were evaluated (complex attention, memory and learning, executive functions, language, motor and perceptual functions) and a detailed evaluation of the executive functions was made by means of a group of specific neuropsychological tests. Results: The statistical analysis demonstrated that comparing the two study groups with cognitive disorder, significant differences exist as for the level of cognitive performance in all the explored domains, except in the perception and motor functions. Likewise, the results demonstrated that the yielding level for each function evaluated within the domain of the executive functions is significantly different between both groups with cognitive disorder, except for the space orientation. Conclusions: The neuropsychological profile of the cognitive disorder Alzheimer possible subtype was characterized by a disorder in multiple domains, with predominance of the focused executive dysfunction in the areas of the mental flexibility and inhibition of automatisms.

[DIABDEM project: A pilot study of prevalence of cognitive impairment in diabetes mellitus in 2 Hispanic countries]. / Proyecto DIABDEM: estudio piloto de la prevalencia de deterioro cognitivo en diabetes mellitus en 2 países hispánicos.

INTRODUCTION: The prevalence of chronic noncommunicable diseases such as type 2 diabetes mellitus (T2DM) and dementia increase with ageing. In this context, an association between T2DM and cognitive impairment has been described in the literature. However, there are few studies in the Hispanic population. This research project presents a pilot study that will evaluate the feasibility of the DIABDEM project that will determine the prevalence of cognitive impairment in old people with diagnosis of T2DM in Spain and Chile. MATERIALS AND METHODS: It is a observation-based pilot study, non-experimental, descriptive-comparative and cross-sectional. The sample will involve 72 participants (39 Spaniards and 33 Chileans), 65 year-old or older, men and women, community dwelling, and who have not been previously diagnosed with dementia, with or without a T2DM diagnosis. Participants will fill in a research protocol form collecting socio-demographic and clinical data, lifestyle details, and neuropsychological variables. EXPECTED RESULTS: This study will evaluate the feasibility of the DIABDEM project that will determine the prevalence rate of cognitive impairment in old people with T2DM. On one hand, the aim of this study will establish risk and protectors factors potentially associated with the development of cognitive impairment in T2DM. On the other hand, it is expected to identify a specific neuropsychological profile in people with T2DM, proposing later a brief and useful neuropsychological battery in order to discriminate early cognitive impairment in people with T2DM. CONCLUSION: Findings in this pilot study will obtain greater knowledge about the feasibility of the DIABDEM project, which will provide evidence about cognitive complications in T2DM.

Rendimiento Diagnóstico De Minimental Frente Al Dsm-5 En Trastorno Cognitivo: Experiencia De Una Cohorte En Colombia / Diagnostic Performance Of Minimental Against Dsm-5 In Cognitive Disorder. Experience Of A Cohort In Colombia

Resumen Antecedentes: Las herramientas de cribado cognitivo son útiles en el escenario clínico e investigación. MiniMental (MMSE) es uno de los instrumentos más utilizados en Colombia. El objetivo de este trabajo es determinar el rendimiento operativo del MMSE, frente a los nuevos criterios del DSM-5 para el diagnóstico de trastorno cognitivo. Materiales y métodos: Estudio de prueba diagnóstica ensamblado en una cohorte colombiana, se evaluó una muestra consecutiva de 200 participantes mayores de 50 años (66.5,+/-8.86) que representaron todo el espectro de la condición de interés, la prueba índice (MMSE) fue comparada con el estándar clínico de referencia (consenso diagnóstico y clasificación por criterios DSM-5). Resultados: Para trastorno cognitivo leve (TCL), el rendimiento diagnóstico de MMSE fue: Sensibilidad 45.3%(IC95% 33.7 a 57.4), especificidad 96.9% (IC95% 91.4 a 99.0) y exactitud del 76.9% (IC 95% 69.5 a 82.4) a un punto de corte de 26 y para trastorno cognitivo mayor (TCM) fue: Sensibilidad 76.32% (IC 95% 60.8-87.0) y especificidad 97.53% (IC 95% 93.8-99.0) en el punto de corte de 24. Conclusiones: MMSE continúa siendo una alternativa válida para diagnóstico de TCM, sin embargo, tiene limitada validez para la detección de TCL, por lo que nuevas herramientas con objetivo de cribado de TCL deben ser consideradas.

Abstract Background: Cognitive screening tools are useful in the clinical and research setting. MiniMental (MMSE) is one of the most used instruments in Colombia, the objective of this work is to determine its performance against the new criteria for the diagnosis of cognitive disorder (DSM-5). Materials and methods: Diagnostic test study, assembled in a Colombian cohort, we evaluated a consecutive sample of 200 participants older than 50 years (66.5,+/-8.86) that represented the whole spectrum of the condition of interest, the index test (MMSE) was compared with the clinical reference standard (consensus diagnosis and classification by criteria DSM-5). Results: For mild cognitive impairment (MCI), the diagnostic performance of MMSE was: Sensitivity 45.3% (95% CI 33.7 to 57.4), specificity 96.9% (95% CI 91.4 to 99.0) and 76.9% accuracy (95% CI 69.5 to 82.4) at a cut-off point of 26 and, for major cognitive disorder (MCD) was: Sensitivity 76.32% (95% CI 60.8-87.0) and specificity 97.53% (95% CI 93.8-99.0) at the cut-off point of 24. Conclusions: MMSE is a valid alternative for the diagnosis of MCD, however it has limited validity for the detection of MCI, so new tools for the purpose of screening of MCI should be considered.

Sindrome de embolismo graso con predominio de sintomas neurologicos / Fat embolism syndrome with predominance of neurological symptoms

El sindrome de embolismo graso hace referencia a un conjunto de signos y sintomas secundarios a la liberacion de lipidos dentro de la circulacion sanguinea. Ocurre en alrededor del 1% de los pacientes con fracturas de femur. La triada clasica de este sindrome incluye dificultad respiratoria con hipoxemia, alteracion neurologica y exantema petequial. Pese a las descripciones aisladas que documentan la mejoria de los sintomas despues de administrar corticoides, no existe clara evidencia de la utilidad de estos farmacos, por lo que el manejo actual consiste en soporte cardiovascular y respiratorio. Se presenta un paciente adulto joven con sindrome de embolismo graso y manifestaciones respiratorias minimas tras una fractura traumatica de femur.

Fat embolism syndrome refers to a set of signs and symptoms caused by the release of fat in the bloodstream. It occurs in about 1% of patients with femur fractures. The classic triad includes respiratory distress with hypoxemia, neurologic impairment and petechial rash. Isolated reports document symptom improvement after administration of corticosteroids, but solid evidence of the usefulness of these drugs is lacking; therefore current management includes cardiovascular and respiratory support. We present a young adult patient with fat embolism syndrome and minimal respiratory symptoms after traumatic femoral fracture.

Questões e controvérsias metodológicas da pesquisa em desordens cognitivas / Methodological issues and controversies in research on cognitive disorders

Research on cognitive disorders is challenging due to the complexity of functions studied and to the numerous variables involved. First, the concept of cognition as a mediated (semiotic) and systemic activity is reviewed. According to this concept, the result of a local lesion is not an isolated symptom but a syndrome, and the best neuropsychological approach is an analysis based on appropriate tests to disclose double dissociations and thereby provide clues to brain-behavior relationships. This approach takes into account the influence of task-relevant variables (confounders) related to the patient (e.g., age, education), to the lesion (size, etiology), and to the tests and testing conditions (ecological validity, examiners experience), which need to be controlled and analyzed in multivariate statistical analyses, as illustrated in research on medial temporal lobe epilepsy. Other controversial issues such as single and double dissociations, single-case versus group studies, and the lesion method are also examined.

O estudo das desordens cognitivas é tarefa dificil devido à complexidade das funções estudadas e às numerosas variáveis implicadas. Neste artigo, nós primeiro revisitamos o conceito de cognição como atividade sistêmica e mediada (semiótica), de acordo com o qual a consequência de uma lesão focal não é um sintoma isolado mas uma syndrome, e a melhor abordagem neuropsicológica é uma análise baseada em testes apropriados para detectar dissociações duplas e, assim, fornecer pistas para relações cerebro-comportamentais. Esta abordagem leva em conta a influência de variáveis que podem influenciar o desempenho nos testes, as quais podem estar relacionadas ao paciente (idade, educação, etc.), à lesão (tamanho, etiologia), aos testes ou condições da testagem (validação ecológica, experiência do examinador), as quais precisam ser controladas e incluídas em análises estatísticas multivariadas, tal como fazemos em estudos de epilepsia de lobo temporal medial. Outras questões controversas, tais como dissociações simples e duplas, estudos de casos isolados versus estudos de grupos, bem como o método lesional são também examinados.

Comparison of the Mini Mental State Examination and depressive symptoms between high cardiovascular risk and healthy community elderly groups.

The aging of the population is a universal phenomenon with direct consequences upon the public health system. One of the main repercussions of the growth in this sector of the population is the increased prevalence of disorders such as dementia and depression which are very frequent among the elderly. The relationship between cardiovascular risk factors, dementia and depression have been addressed in many recent investigations. OBJECTIVES: To evaluate the relationship of cognitive performance and depressive symptoms with cardiovascular risk in the elderly. METHODS: 94 high cardiovascular risk elderly patients and 160 healthy community elderly were evaluated cross-sectionally. The Mini Mental State Examination (MMSE) and the Geriatric Depression Scale (GDS-15) were used as the main measures. The cutoff for presence of depression was 6 on the GDS. RESULTS: The high cardiovascular risk elderly group showed significantly lower scores on the MMSE (p<0.001) and was significantly associated to depression (p<0.001), independently of education. The logistic regression analysis for depression as the dependent variable, age and group (healthy community or high cardiovascular risk elderly) were kept in the final equation. Higher age (Odds Ratio=0.92; 95% CI 0.86-0.98) and high cardiovascular risk elderly (OR=2.99; 95% CI 1.36-6.59) were associated to depression. CONCLUSIONS: The present findings corroborate the different cognitive performance of elderly with high cardiovascular risk factors and the association of depressive symptoms with this group.

O envelhecimento da população é um fenômeno mundial com conseqüências diretas no sistema de saúde pública. Uma das principais conseqüências do crescimento desta parcela da população é o aumento da prevalência de doenças como demência e depressão que são muito freqüentes entre os idosos. Recentemente, a relação entre fatores de risco cardiovasculares, depressão e demência foi abordada em várias investigações. OBJETIVOS: Avaliar a relação de desempenho cognitivo e sintomas depressivos com risco cardiovascular em idosos. MÉTODOS: 94 idosos de alto risco cardiovascular e 160 idosos saudáveis da comunidade foram avaliados num corte transversal. O Mini-Exame do Estado Mental (MEEM) e a escala de depressão geriátrica (GDS-15) foram usados para as medidas principais. O ponto de corte para presença de sintomas depressivos foi 6 na GDS. RESULTADOS: O grupo de alto risco cardiovascular mostrou escores significativamente mais baixos no MEEM (p<0001) independente da educação, e foi significativamente associado a depressão (p<0,001). A análise de regressão logística para depressão como variável dependente, idade e grupo (idosos saudáveis da comunidade ou idosos de alto risco cardiovascular) foram mantidos na equação final. Maior idade (Razão de Chance=0,92, IC 95% 0,86­0,98) e idosos de alto risco cardiovascular (RC=2,99; IC 95% 1,36­6,59) estavam associados à presença de depressão. CONCLUSÕES: Os achados do presente estudo corroboram o desempenho cognitivo diferencial dos idosos de alto risco cardiovascular e a associação de sintomas depressivos a este grupo.
