Semantic verbal fluency in elderly Mexican adults: Reference values.

INTRODUCTION: The semantic verbal fluency test (SVF) is sensitive to detecting cognitive decline. It is fast and easy to use in any cultural context; therefore, it is included in most of the neuropsychological assessment protocols. OBJECTIVE: To estimate normative values for the SVF test (animals), in an elderly population aged 65 years and over. MATERIAL AND METHOD: 1233 subjects who were healthy, cognitively preserved, residents of two areas (rural and urban) of Mexico were assessed. A neurological and neuropsychological exploration battery was applied, including SVF. RESULTS: The age average was 73+6 and schooling was 4.0+3.9 years, with 59% women. The average of the words generated in the SVF test was 14+5, and a correlation of 0.16 of these scores with age, education, and gender was found (p<.001), this allowed the estimation of the percentiles in accordance with these variables. CONCLUSIONS: The most important contribution provided by this study was that the data analysis enabled normative values to be obtained for an elderly Mexican population aged 65 years and over. It was also confirmed, as other neuropsychological assessment studies have done, that the SVF test is influenced by socio-demographic variables, such as age and education, aspects to be considered at the time of obtaining normative values. Finally, it was noted that the average scores obtained were lower than other published reference values, due to the low educational level of our sample.

Validation of the Spanish version of Addenbrooke's Cognitive Examination III for diagnosing dementia.

INTRODUCTION: Addenbrooke's Cognitive Examination is a screening test used to diagnose dementia. The third edition of this test (ACE-III) was recently developed. The aim of this study was to translate and validate the ACE-III in Spanish. METHODS: The ACE-III was translated and adapted to Spanish. It was then administered to a group of healthy subjects as well as a group of patients with different types of mild dementia treated in 2 hospitals in Spain. RESULTS: Internal reliability (Cronbach's alpha = 0.927), inter-rater reliability (intraclass correlation coefficient = 0.976) and test-retest reliability (kappa 0.995) were excellent. Age (r = -0.512) and education (r = 0.659) showed a significant correlation with total test scores. The diagnostic accuracy of ACE-III was higher than that of the Mini-Mental State Examination, particularly for the group with the highest educational level. Researchers obtained normative data and cut-off points for the diagnosis of dementia. CONCLUSIONS: The Spanish version of the ACE-III is a reliable and valid test for diagnosing dementia. Its diagnostic accuracy is high, especially in patients with a higher level of education.

Psychometric properties of a new short version of the State-Trait Anxiety Inventory (STAI) for the assessment of anxiety in the elderly.

INTRODUCTION: Anxiety has negative effects on the cognitive performance and psychosocial adjustment of elderly people. Given the high prevalence of anxiety symptoms in patients suffering from cognitive impairment, it has been suggested that these symptoms may be an early marker of dementia. The State-Trait Anxiety Inventory (STAI) is one of the most widely-used scales for evaluating anxiety in elderly people. However, inasmuch as the STAI may be difficult to apply to older people, having a short form of it would be desirable. METHODS: The participants comprised 489 community-dwelling individuals aged 68 years and over. All of them were volunteers in a longitudinal study for early detection of Alzheimer' Disease (Proyecto Vallecas). The full sample was divided in two homogeneous subgroups: Group A, used to reduce the number of items and response options, and Group B, the group used to determine the psychometric properties of the new short form (STAIr). RESULTS: A dichotomous Rasch model was used to obtain the STAIr. No statistically significant differences for STAIr scores were found with respect to sociodemographic variables. Psychometric properties and normative data were obtained for the new short version. CONCLUSIONS: The STAIr is composed of 13 items and data fits the model well. Since it is short and easy to apply to elderly people, STAIr will be very useful in clinical and research settings.

[Neuropsychological impairments in patients undergoing peritoneal dialysis treatment]. / Alteraciones neuropsicológicas en pacientes en tratamiento con diálisis peritoneal.

BACKGROUND: Patients with chronic kidney disease on hemodialysis (HD) often have cognitive deficits. However, there are few studies that have examined the neuropsychological impairments of patients receiving peritoneal dialysis (PD). METHODS: Executive functions, processing speed and verbal memory were assessed in 27 PD patients, 42 HD patients, and 42 healthy participants (HP). Systolic blood pressure and total time on renal replacement therapy (RRT) were controlled statistically. Associations between performance and clinical factors were analyzed using correlations and multiple regression. RESULTS: The DP group showed better performance compared to the HD group in verbal fluency, working memory, cognitive flexibility, planning and decision making. The DP group showed worse execution than the HP group in verbal inhibition and memory. Executive function scores were positively associated with total months on PD, total months on RRT, total months on HD, albumin, total cholesterol, and phosphorus, and negatively with ferritin. CONCLUSION: Global executive functioning was more optimal in PD patients than in HD patients. The results show the positive effect of PD on executive functions, which must be taken into account when choosing the TRS. The associations observed between biochemical factors and performance show the importance of maintaining an adequate nutritional status in these patients.

Evaluating executive function in schoolchildren with symptoms of attention deficit hyperactivity disorder.

OBJECTIVE: To identify impairment of executive functions (EF) in children with attention deficit hyperactivity disorder (ADHD). SUBJECTS AND METHODS: A case-control study was performed on a sample of schoolchildren with low socioeconomic levels in Bogota, Colombia. ADHD was diagnosed using the DSM IV checklist and the Behavior Assessment System for Children scale. Children with cognitive deficits were excluded. We evaluated scores from six measurements of executive function (EF). We conducted a bivariate statistical analysis to compare the variables, a multivariate study controlled by sex and age, and a logistic regression analysis. RESULTS: The study sample included 119 children with ADHD and 85 controls, all aged between 6 and 12 years. Controlling by sex, age, and type of school showed that EF measurements in children with ADHD were significantly more impaired than in controls, especially for measurements of verbal and graphic fluency, Rey-Osterrieth Complex Figure, and cognitive flexibility. Comparison of ADHD subgroups showed that results in children with multiple deficits were similar to those in the global ADHD group. Graphic fluency impairment was the sole impairment in cases with only attention deficit or only hyperactivity-impulsivity manifestations. CONCLUSIONS: EF measures in children with ADHD revealed more problems, particularly those having to do within planning, inhibition, working memory and cognitive control. Age and sex may affect the degree of EF impairment.

Standardised results of the Montreal Cognitive Assessment (MoCA) for neurocognitive screening in a Chilean population.

INTRODUCTION: Population ageing poses a challenge for countries in preventing and detecting neurodegenerative disorders. The Montreal Cognitive Assessment (MoCA), a short, simple, valid, and reliable screening test, assesses general cognitive status, and is useful in public health contexts. This study aims to normalise and standardise the MoCA test for the Chilean population. METHOD: We performed a descriptive, correlational validation study of the MoCA test, using a sample including 526 healthy individuals of both sexes, aged between 18 and 90 years, from the north, centre, and south of Chile. We analysed the effects of age, education level, and sex on MoCA performance. RESULTS: Age and education level had a significant impact on general cognitive performance, as determined by MoCA score. Age, education, and sex account for 1%-7% of variance. The mean (standard deviation) score for the total sample was 24.04 (3.22), whereas the normal range originally defined for the instrument is 26-30 points. Older adults with less formal education presented poorer results and lower cognitive performance. We propose a protocol for evaluating results by percentiles and scores for different age ranges, and an individual normalised scalar score. DISCUSSION: We present normative data for the MoCA test in the Chilean population, and propose cut-off points for different age ranges to discriminate normal cognitive performance from neurocognitive disorders; results are adjusted for education level. This proposal would assist in the use of the test and reduce the rate of false positives.

Assessment of long-term cognitive dysfunction in older patients who undergo heart surgery.

INTRODUCTION: Older patients are more likely to have cognitive dysfunction, and a great proportion of patients undergone surgical procedures are older adults. Postoperative cognitive dysfunction (POCD) has been shown as a consistent complication after major surgical procedures such as heart surgery. AIM: To determine the presence of long-term POCD in ≥65-year-old patients undergoing coronary artery bypass grafting and aortic valve replacement, and to establish related risk factors. METHODS: We prospectively and sequentially included 44 patients with coronary disease and aortic stenosis scheduled for heart surgery. Follow-up of all patients was standardized and a neurocognitive evaluation were performed preoperatively and at 1, 6 and 12 months after surgery. RESULTS: Patients experienced a significantly postoperative cognitive dysfunction (33.5%, 63.4% and 38.9% at 1, 6 and 12 months, respectively) from baseline (20.5%). Patient-associated aspects such as age (p<0.01), history of smoking (p<0.01), arterial hypertension (p=0.022), diabetes mellitus (p=0.024), heart failure (p=0.036) and preoperative cognitive dysfunction (p<0.01), and surgery-associated aspects such as EuroSCORE (p<0.01) and operation time (p<0.01) were identified as related risk factors. CONCLUSIONS: Older patients who underwent heart surgery had long-term POCD. Both patient- and surgery-related risk factors were established as related risk factors. These findings suggest that the prevalence of cognitive dysfunction after cardiac surgery in older patients could be related to a possible progression to dementia. In addition, many of the risk factors identified may be modifiable but in practice, these patients are not attended to for their possible cognitive impairment.

Comparative study of the word capacity and episodic memory of patients with degenerative dementia.

INTRODUCTION: Although the absence of memory impairment was considered among the diagnostic criteria to differentiate Alzheimer's disease (AD) from Behavioural Variant of Frontotemporal Dementia (bvFTD), current and growing evidence indicates that a significant percentage of cases of bvFTD present with episodic memory deficits. In order to compare the performance profile of the naming capacity and episodic memory in patients with AD and bvFTD the present study was designed. METHODS: Cross-sectional and analytical study with control group (32 people). The study included 42 people with probable AD and 22 with probable bvFTD, all over 60 years old. Uniform Data Set instruments validated in Spanish were used: Multilingual Naming Test (MINT), Craft-21 history and Benson's complex figure, among others. RESULTS: A higher average age was observed among the patients with AD. The naming capacity was much lower in patients with bvFTD compared to patients with AD, measured according to the MINT and the nouns/verbs naming coefficient. All patients with bvFTD, 73.81% of those with AD and only 31.25% of the control group failed to recognise Benson's complex figure. All differences were statistically significant (p < 0.001). RESULTS: This study confirms the amnesic profile of patients with AD and reveals the decrease in naming capacity in patients with bvFTD, an area of ​​language that is typically affected early on with executive functions, according to recent findings. CONCLUSIONS: Patients with AD perform worse in verbal and visual episodic memory tasks, while patients with bvFTD perform worse in naming tasks. These findings open the possibility of exploring the mechanisms of prefrontal participation in episodic memory, typically attributed to the hippocampus.

[Normative data of the abbreviated-revised Barcelona test for cognitively active elderly people]. / Datos normativos del test Barcelona revisado-abreviado para personas mayores cognitivamente activas.

INTRODUCTION: Neuropsychological assessment is mandatory in order to identify cognitive changes that occur during either normal or pathological aging. However, normative data adapted to the characteristics of the population are needed in order to reduce the probability of false diagnoses of cognitive impairment. The aim of the present work was to compute normative data for cognitively active elderly people attending a University course for the elderly. MATERIALS AND METHODS: An analysis was performed on the data from 87 participants (70.9% women) with a mean age of 66.73 years who undertook the abbreviated- revised Barcelona test (test de Barcelona revisado-abreviado). Normative data were calculated using linear regressions controlling for age, gender, and years of education. Adjusted normative data were compared with normative data available from the test manual and obtained from the general population. RESULTS: Years of education and gender showed the highest weights in the regression model. Normative data for cognitively active older adults showed a different number of low scores compared to normative data from the general population. The number of low scores were related to years of education and general cognitive functioning. CONCLUSIONS: Normative data obtained from cognitively active older people could help identify more accurately the cognitive functioning of cognitively active older people than do normative data obtained from the general population.

Funções neuropsicológicas de meninas privadas de liberdade em unidade socioeducativa / Neuropsychological functions of girls deprived of liberty in socio-educational unit / Funciones neuropsicológicos de niñas privadas de libertad en unidad socioeducativa

OBJETIVO: A avaliação neuropsicológica tem alta relevância na adolescência e em situação de conflito com a lei, com privação de liberdade em instituições socioeducativas, pode auxiliar, compondo abordagens psicossociais que identifiquem as funções neuropsicológicas, situando-as a partir da historicidade do indivíduo. Deste modo, para compreender esse problema, foi objetivo desse estudo avaliar e descrever as funções neuropsicológicas de adolescentes meninas privadas de liberdade em instituição socioeducativa. MÉTODOS: As participantes foram 19 meninas avaliadas com os instrumentos: Barratt Scale, Inventário de Expressão de Raiva, teste Wisconsin de classificação de cartas, protocolo neuropsicológico, questionário para uso de drogas e Hare Psychopathy Checklist Revised. RESULTADOS: O uso de drogas na vida ocorreu em 80,0% dos casos. Verificaram-se altos escores de impulsividade total (M=75,8, DP=5,4), traço de raiva (M=24,5, DP=7,3) e respostas perseverativas (M =38,5, DP =19,9). Em conjunto com PCL-R total (M=17,5, DP=3,6) e com QI total (M=79,1, DP=16,2), esses níveis auxiliaram na caracterização das funções de autocontrole. CONCLUSÕES: Os dados foram interpretados como indicativos de baixo funcionamento executivo, altos níveis de raiva, de impulsividade, de uso de drogas e de traços de psicopatia. Foram relatadas adversidades durante a infância, o que pode ter contribuído para um desempenho prejudicado nas funções cognitivas e emocionais dessas meninas.

OBJECTIVE: Neuropsychological assessment is highly relevant in adolescence and in situations of conflict with the law, with deprivation of liberty in socio-educational institutions, it can help, composing psychosocial approaches that identify neuropsychological functions, situating them based on the individual's historicity. Therefore, to understand this problem, the objective of this study was to evaluate and describe the neuropsychological functions of adolescent girls deprived of liberty in a socio-educational institution. METHODS: The participants were 19 girls evaluated with the following instruments: Barratt Scale, Anger Expression Inventory, Wisconsin Card Sorting Test, Neuropsychological protocol, drug use questionnaire and Hare Psychopathy Checklist Revised. RESULTS: Lifetime drug use occurred in 80.0% of cases. There were high scores for total impulsivity (M=75.8, SD=5,4), trait anger (M=24.5, SD=7.3) and perseverative responses (M=38.5, SD=19.9). Together with total PCL-R (M=17.5, SD=3.6) and total IQ (M=79.1, SD=16), these levels helped to characterize self-control functions. CONCLUSIONS: The data were interpreted as indicating low executive functioning, high levels of anger, impulsivity, drug use and psychopathic traits. Adversities were reported during childhood, which may have contributed to impaired performance in the cognitive and emotional functions of these girls.

Evolución de la afasia en adolescentes con secuela de ACV: serie de casos / Post-stroke aphasia in adolescents' progress: case series

La afasia como secuela de un accidente cerebrovascular es un trastorno del lenguaje poco estudiado en adolescentes, tanto en Latinoamérica como a nivel mundial. Independientemente del hecho de que un número significativo de afasias mejora espontáneamente, la necesidad del inicio oportuno del tratamiento es imprescindible. En esta serie de casos se describe la presentación clínica y evolución de la afasia en 3 adolescentes con secuelas de accidente cerebrovascular que ingresaron a un instituto de neurorehabilitación. Fueron dos mujeres y un varón, de entre 15 y 17 años, que recibieron rehabilitación integral intensiva desde las áreas de fisioterapia, terapia ocupacional, neuropsicología, psicopedagogía, musicoterapia y fonoaudiología. Fueron evaluados con la versión chilena de la herramienta Western Aphasia Battery (WAB). A los 3 meses todos mejoraron y evolucionaron a un tipo de afasia más leve. Este estudio expone la importancia del tratamiento precoz e intensivo en esta población de adolescentes en plena etapa de construcción social como personas, en donde la alteración del lenguaje impacta en sus vínculos, grupo de pertenencia, estado anímico y a nivel académico. Se considera fundamental la evaluación y seguimiento sistemático con el objetivo de identificar los cambios y avances alcanzados durante la rehabilitación.

Aphasia as a sequela of stroke is an understudied language disorder in adolescents, both in Latin America and worldwide. Although a significant number of aphasia cases improve spontaneously, it is necessary to initiate treatment as soon as possible. This cases series describes the clinical presentation and evolution of aphasia in 3 adolescents with stroke sequelae who were admitted to a neurorehabilitation facility. Two females and one male, aged between 15 and 17 years, received intensive comprehensive rehabilitation from the areas of physiotherapy, occupational therapy, neuropsychology, psychopedagogy, music therapy and speech therapy. They were evaluated with the Chilean version of the Western Aphasia Battery (WAB). After 3 months, all of them improved and evolved to a milder type of aphasia. This study shows the importance of early, intensive treatment in adolescents who are in the height of their social development, where language alteration impacts on their bonds, their groups of belonging, their mood and their academic process. Systematicassessment and follow-up are considered essential to identify the changes and progress achieved during rehabilitation.

Características Cognitivas e Comportamentais Associadas à Distrofia Muscular de Duchenne: Revisão Integrativa / Cognitive and Behavioral Characteristics Associated with Duchenne Muscular Dystrophy: Integrative Review / Características Cognitivas y de Comportamiento Asociadas con la Distrofia Muscular de Duchenne: Revisión Integrativa

A Distrofia Muscular de Duchenne (DMD) é uma doença neuromuscular progressiva recessiva causada por mutações genéticas ligadas ao cromossomo X. Além do enfraquecimento muscular progressivo, a condição é associada a alterações neuropsicológicas. O objetivo deste estudo foi realizar uma revisão sistematizada da temática, para investigar os aspectos cognitivos e comportamentais associados à DMD pela literatura, nos últimos dez anos (2011-2021). Realizou-se uma revisão integrativa da literatura, com o propósito de sintetizar e analisar o conhecimento sobre o tema no campo científico, sendo efetuada busca nas bases de dados e motores de busca Science Direct, SciELO, PubMed e BVS. Após consideração dos critérios de inclusão e exclusão, foram selecionados 29 artigos para análise. Os resultados endossaram que alterações cognitivas e do neurodesenvolvimento, bem como de problemas comportamentais parecem ser mais prováveis na DMD, em comparação com a população geral. Verificou-se escassez de estudos empíricos brasileiros e a necessidade de avaliar e intervir nos âmbitos neuropsicológico e psicossocial, de forma precoce, contínua e multidisciplinar, no intuito de atender às necessidades desse grupo.

Duchenne Muscular Dystrophy (DMD) is a recessive progressive neuromuscular disease caused by X-linked genetic mutations. In addition to progressive muscle weakness, the condition is associated with neuropsychological alterations. The aim of this study was to perform a systematic review about the theme, to investigate the cognitive and behavioral aspects associated with DMD in the literature, over the last ten years (2011-2021). An integrative literature review was carried out, with the purpose of synthesizing and analyzing the knowledge on the subject in the scientific field, with a search in the databases and search engines Science Direct, SciELO, PubMed and BVS. After considering the inclusion and exclusion criteria, 29 articles were selected for analysis. The results endorsed that cognitive and neurodevelopmental alterations and behavioral problems seem to be more likely in DMD, when compared to the general population. There was a lack of brazilian empirical studies and the need to assess and intervene in the neuropsychological and psychosocial spheres was observed, in an early, continuous and multidisciplinary way, in order to meet the needs of this group.

Assessment of long-term cognitive dysfunction in older patients who undergo heart surgery / Deterioro cognitivo a largo plazo tras cirugía cardiaca en pacientes de edad avanzada

Introduction: Older patients are more likely to have cognitive dysfunction, and a great pro-portion of patients undergone surgical procedures are older adults. Postoperative cognitivedysfunction (POCD) has been shown as a consistent complication after major surgical proceduressuch as heart surgery.Aim: To determine the presence of long-term POCD in ≥65-year-old patients undergoing coro-nary artery bypass grafting and aortic valve replacement, and to establish related risk factors.Methods: We prospectively and sequentially included 44 patients with coronary disease andaortic stenosis scheduled for heart surgery. Follow-up of all patients was standardized anda neurocognitive evaluation were performed preoperatively and at 1, 6 and 12 months aftersurgery.Results: Patients experienced a significantly postoperative cognitive dysfunction (33.5%, 63.4%and 38.9% at 1, 6 and 12 months, respectively) from baseline (20.5%). Patient-associated aspectssuch as age (p < 0.01), history of smoking (p < 0.01), arterial hypertension (p = 0.022), diabetesmellitus (p = 0.024), heart failure (p = 0.036) and preoperative cognitive dysfunction (p < 0.01),and surgery-associated aspects such as EuroSCORE (p < 0.01) and operation time (p < 0.01) wereidentified as related risk factors. Conclusions: Older patients who underwent heart surgery had long-term POCD. Both patient-and surgery-related risk factors were established as related risk factors. These findings suggestthat the prevalence of cognitive dysfunction after cardiac surgery in older patients could berelated to a possible progression to dementia. In addition, many of the risk factors identifiedmay be modifiable but in practice, these patients are not attended to for their possible cognitiveimpairment.(AU)

Introducción: Los pacientes de edad avanzada tienen más riesgo de sufrir deterioro cognitivo, yson cada vez más frecuentemente sometidos a una cirugía. El deterioro cognitivo posquirúrgico(DCP) tras cirugía cardiaca se ha mostrado como una complicación importante.Objetivos: Determinar la presencia del DCP a largo plazo en pacientes ≥ 65 a˜nos intervenidosde derivación coronaria y reemplazo de válvula aórtica, y establecer los factores de riesgorelacionados.Métodos: Se realizó un estudio en el que se incluyeron de forma prospectiva y secuen-cial 44 pacientes con enfermedad coronaria y estenosis aórtica programados para cirugía. Elseguimiento fue estandarizado y se realizaron evaluaciones neuropsicológicas preoperatoria-mente a los 1, 6 y 12 meses postoperatorios.Resultados: Se observó la presencia de un DCP significativo (33,5, 63,4 y 38,9% a 1, 6 y 12 meses,respectivamente) respecto al nivel basal (20,5%). Se identificaron como factores de riesgo varia-bles asociadas al paciente como la edad (p < 0,01), el tabaquismo (p < 0,01), la hipertensiónarterial (p = 0,022), la diabetes mellitus (p = 0,024), la insuficiencia cardiaca (p = 0,036) y el dete-rioro cognitivo preoperatorio (p < 0,01), y variables quirúrgicas como el EuroSCORE (p < 0,01) yel tiempo de intervención (p < 0,01).Conclusiones: Los pacientes de edad avanzada sometidos a cirugía cardiaca presentaron DCP alargo plazo. Variables asociadas al paciente y quirúrgicas se mostraron como factores de riesgo,muchas de ellas modificables. Estos hallazgos sugieren que la presencia de DCP en pacientes demás edad podría suponer mayor riesgo de evolución a demencia. En la práctica clínica habitualno es evaluado el rendimiento cognitivo.(AU)

O Paradigma de Stroop nos estudos brasileiros: uma revisão de escopo / The Stroop Paradigm in Brazilian studies: a scope review / El Paradigma de Stroop en los estudios brasileños: una revisión del alcance

O paradigma do Stroop é amplamente utilizado na avaliação das funções executivas. Este estudo investigou o uso de tarefas baseadas no paradigma de Stroop em estudos nacionais publicados entre 2000 e 2022, por meio de uma revisão de escopo. Buscaram-se estudos empíricos nas bases de dados: Pubmed, Scielo Brazil, LILACS, Pepsic, Index Psi Periódicos, Index-Psi teses, Biblioteca Digital Brasileira de Teses e Dissertações (BDTD) e Portal CAPES de Teses e Dissertações. Do montante inicial de 1448 estudos, 147 foram selecionados (90 teses/dissertações e 57 artigos). A maioria dos artigos foi publicada em revistas de psicologia e psiquiatria, e o controle inibitório foi o constructo mais mencionado como alvo das tarefas. Quatro versões foram identificadas, sendo a mais utilizada o Stroop de cores e palavras clássico (124 estudos). Diferentes escores/índices foram relatados. Houve poucos estudos psicométricos e com normas das tarefas. Versões computadorizas ainda são pouco utilizadas. A revisão colabora para mapeamento das versões utilizadas no âmbito nacional.

The Stroop paradigm is widely used in the executive functions assessment. This study investigated the use of tasks based on the Stroop paradigm in national studies published between 2000 and 2022, by doing a scope review. Empirical studies were selected in the following databases: Pubmed, Scielo Brazil, LILACS, Pepsic, Index Psi Periódicos, Index-Psi teses, Biblioteca Digital Brasileira de Teses e Dissertações (BDTD) and Portal CAPES de Teses e Dissertações. From the initial 1448 studies found, 147 were selected (90 theses/dissertations and 57 articles). Most articles were published in psychology and psychiatry journals, and the construct most targeted by the tasks was inhibitory control. Four versions were identified, and the classic Stroop Color and Word test was the most used one (124 studies). Different scores were reported. There were few psychometric studies and few studies with task norms. Computerized versions are still little used. The review helps to outline the versions used at the national context.

Reflexões sobre o trabalho on-line da neuropsicologia infantil numa visão histórico-cultural / Reflections on the online work of child neuropsychology from a cultural-historical perspective / Reflexiones sobre el trabajo online de la neuropsicología infantil desde una perspectiva histórico-cultural

O isolamento social provocado pela pandemia de covid-19 exigiu uma intensificação no estabelecimento de parâmetros para o trabalho do neuropsicólogo com suas especificidades. Assim, o objetivo deste artigo é levantar reflexões sobre a prática neuropsicológica infantil via internet baseada na nossa experiência prática vivenciada no período, relacionando com as referências teóricas da abordagem histórico-cutural e outros trabalhos que discorrem sobre as particularidades dessa modalidade de atendimento. Para isso, foi realizada uma pesquisa bibliográfica em fontes reconhecidas, como SciELO e Google Acadêmico, utilizando-se marcadores como "neuropsicologia on-line" e "teleneuropsicologia", entre outros, em português, inglês e espanhol. Os trabalhos encontrados foram utilizados como fundamento para discutir as ideias aqui apresentadas, a partir da experiência dos autores durante esse período. Considera-se que os neuropsicólogos precisam enfrentar a possível necessidade do trabalho on-line, considerando que as situações vividas durante a pandemia tendem a aumentar a necessidade de avaliações e intervenções neuropsicológicas. Ao mesmo tempo, se prevê que essa via de trabalho deve se intensificar após o isolamento, dentro do que se tem denominado como "o novo normal". Para isso, é essencial que haja esforço por parte da comunidade neuropsicológica para mostrar como essa área de trabalho pode ser útil para crianças, seus pais e professores. Conclui-se que é preciso ter a noção de que nenhuma via ou metodologia de trabalho é absolutamente completa, sendo essencial a instrumentalização das vantagens e desvantagens de todas elas.(AU)

The social isolation caused by the COVID-19 pandemic demanded intensification in the establishment of parameters for the neuropsychologist's work with its specificities. Thus, the aim of this article is to raise reflections on child neuropsychological practice via the internet, based on our practical experience in this period, relating to the theoretical references of the cultural-historical approach and other works that discuss the particularities of this type of care. For this, a bibliographic research was carried out in recognized sources such as SciELO and Google Scholar, using markers such as "online neuropsychology" and teleneuropsychology, among others, in Portuguese, English and Spanish. The works found were used as a basis for discussing the ideas presented here which are based on the authors' experience during this period. It is considered that neuropsychologists need to face the possible need for online work, considering that situations experienced during the pandemic tend to increase the need for neuropsychological assessments and interventions. At the same time, it is expected that this work path should intensify after isolation, within of what has been called "the new normal". For this, an effort by the neuropsychological community is essential to show how this area of work can be useful for children, their parents and teachers. It is concluded that it is necessary to have the notion that no way or work methodology is absolutely complete, being essential the instrumentalization of the advantages and disadvantages of all of them.(AU)

Fundamentos teórico-técnicos para la comprensión y detección de la simulación de déficits neurocognitivos / Theoretical-technical foundations for the understanding and detection of the simulation of neurocognitive deficits

La neuropsicología está desarrollándose y migrando a otras áreas tales como la judicial, en donde el neuropsicólogo forense ayuda al juez a tomar decisiones ecuánimes e imparciales, sin embargo, nace como problemática el fenómeno de la simulación de déficits neurocognitivos con el propósito de obtener ganancias secundarias. Este artículo tiene como objetivo abordar dicho fenómeno mediante una sistematización bibliográfica, estableciendo un marco teórico-comprensivo del fenómeno, así como también identificando las principales herramientas para su detección. Se esquematizan apartados que forman un hilo conductor que arrojan como resultado que la detección de la simulación de déficits neurocognitivos es una tarea compleja, multidimensional y que debería tener un enfoque holístico, por lo tanto, es necesario seguir investigando al respecto para perfeccionar sus métodos de identificación.

Neuropsychology is developing and migrating to other areas such as the judicial, where the forensic neuropsychologist helps the judge to make fair and impartial decisions, however, the phenomenon of the simulation of neurocognitive deficits with the purpose of obtaining secondary gains is born as a problem. This article aims to address this phenomenon through a bibliographic systematization, establishing a theoretical-comprehensive framework of the phenomenon, as well as identifying the main tools for its detection. Thus, sections are outlined that form a common thread that show as a result that the detection of the simulation of neurocognitive deficits is a complex, multidimensional task and that it should have a holistic approach, therefore, it is necessary to continue researching in this regard. to perfect its results identification methods.
