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.

Junto con el PCL-R total (M=17,5, DE=3,6) y el CI total (M=79,1, DE=16,2), estos niveles ayudaron a caracterizar las funciones de autocontrol. CONCLUSIONES: Se interpretó que los datos indicaban un bajo funcionamiento ejecutivo, altos niveles de ira, impulsividad, consumo de drogas y rasgos psicopáticos. Se informaron adversidades durante la infancia, que pueden haber contribuido al deterioro del desempeño en las funciones cognitivas y emocionales de estas niñas.

Research progress in neuropsychology of children with tic disorder / 中华实用儿科临床杂志

The nervous system is the carrier of psychological activities, and its functional state directly affects psychological activities.Neuropsychology allows people to understand human psychological activities from the perspective of neuroscience and the correlation between the production of psychological activities and the physiological activities of the brain.It also includes establishing quantitative relationships between human perception, memory, thinking, imagination, attention, personality, intelligence, behavior, and brain function.Neuropsychology is a discipline that studies the relationship between the nervous system and psychological activities and behaviors.Tic disorder (TD) belong to neurodevelopmental disorders and are closely related to neuropsychological states.Studying the neuropsychology of TD is of great significance for their clinical diagnosis and treatment.This article summarizes the current research progress in neuropsychology related to TD in children internationally.

Physical and neuropsychological development of the offspring born to mother with gestational diabetes mellitus at 2 years old / 中国儿童保健杂志

【Objective】 To investigate the physical and neuropsychological development of the offspring born to mothers with gestational diabetes mellitus (GDM) at 2 years of age, and to provide evidence to enhance the physical and neuropsychological development of GDM offspring. 【Methods】 A retrospective analysis was conducted on neonates born in the Department of Obstetrics at Qinzhou Maternal and Child Health Hospital from January 2018 to December 2018 and regularly followed at the outpatient service. The neonates were categorized into two groups based on whether their mothers were diagnosed with GDM during pregnancy: the GDM group (n=243) and the control group (n=362). The general clinical data, follow-up information on physical development and neuropsychological development at 1 year and 2 years of age for all children were collected. Their height, head circumference, body weight, BMI, and Gesell developmental quotients (DQs) at 1 year and 2 years of age for both groups were analyzed. 【Results】 1) There were no significant differences in height, head circumference, body weight, and body mass index (BMI) between the two groups at 1 year and 2 years of age during the follow-up period (P>0.05). 2) At 1 year of age, the GDM group exhibited higher rates of abnormal language development (8.6% vs. 3.3%, χ2=7.854), adaptive behavior(11.4% vs. 5.0%,χ2=8.605), and personal social behavior(8.2% vs. 3.0%, χ2=8.062) compared to the control group (P<0.05), and lower DQs for these Gesell subscales (language development 87.6±7.7 vs. 89.4±9.2, t=2.591; adaptive behavior: 88.4±7.8 vs. 90.5±8.9, t=2.957; personal social behavior: 89.1±7.0 vs. 91.2±7.5, t=3.495, P<0.05). 3) At 2 year of age, the GDM group also showed higher rates of adaptive behavior (8.2% vs. 4.1%, χ2=3.927) and personal social behavior (7.3% vs. 3.0%, χ2=4.093) compared to the control group (P<0.05), and lower DQs for these Gesell subscales (adaptive behavior: 89.5±6.5 vs. 91.9±6.9, t=3.878; personal social behavior: 89.9±7.1 vs. 92.1±6.9, t=3.311, P<0.05). 【Conclusions】 The development of adaptive behavior and personal social behavior in offspring born to mothers with GDM remains delayed. Follow-up for GDM offspring should prioritize achieving a balanced development of adaptive behavior and personal social behavior.

Study of Adaptation and Validity Evidence of the Reading Anxiety Scale (RAS-20) - Version for Parents and Guardians / Estudo de Adaptação e Evidências de Validade da Reading Anxiety Scale (RAS-20) - Versão Para Pais e Cuidadores / Estudio de Adaptación y Evidencia de Validez de la Reading Anxiety Scale (RAS-20) - Versión para Padres y Cuidadores

Abstract: Reading anxiety can hinder involvement and performance. This study aimed to present the adaptation and validity evidence of the Reading Anxiety Scale (RAS-20) for parents and guardians. A total of 240 parents and guardians with children aged from eight to 12 years ( M = 9.73; SD = 1.41) took part in the study. A sociodemographic and health conditions questionnaire, the Child Behavior Checklist (CBCL) and the Reading Anxiety Scale (RAS) version for parents and guardians were applied. The results of the confirmatory factor analysis indicated good adjustment rates for the three dimensions assessed by the scale (enjoyment, independence, and difficulty). Convergent validity evidence supported the hypothesis of anxiety as a specific phenomenon, different from general anxiety. The RAS-Version for parents and guardians showed adequate psychometric properties and can contribute to the development of interventions in the clinical, family, and school context.

Development of the Brazilian version of the Mini-Addenbrooke Cognitive Examination (M-ACE BR) to screen for cognitive impairment in older adults / Desenvolvimento da versão brasileira do Mini-Addenbrooke Cognitive Examination (M-ACE BR) para rastreio de comprometimento cognitivo em idosos

Abstract Background Age is the most important risk factor for develop dementia, and the recommendation is that older adults are cognitively tested to detect impairment in the initial stage for adequate treatment. The demand for the care of these older adults is great, drawing attention to the need for rapid tests, with good accuracy and simple application to identify cognitive impairment. Objective To develop and validate the Brazilian Mini-Addenbrooke Cognitive Examination (M-ACE BR) as a short screening test for cognitive impairment in older adults. Methods The M-ACE BR was developed using the Mokken scaling analysis in 352 participants (cognitively unimpaired [CU] = 232, cognitive impairment no dementia [CIND] = 82; and dementia = 38) and validated in an independent sample of 117 participants (CU = 25; CIND = 88; and dementia = 4). Results The Mokken scaling analysis derived 9 items (spatial orientation, anterograde memory, retrograde memory, delayed recall, recognition [name and address], letter verbal fluency, repetition of 4 words, naming of 10 items, and comprehension) with a maximum score of 51 points and an average duration time of 7 minutes. The cut-off score ≤ 43/51 for CIND had a sensitivity of 59.09% and a specificity of 80%. For a screening test in which sensitivity is prioritized for further investigation, we suggest using a cutoff of ≤ 47 (sensitivity 85.23% and specificity 24%), maintaining a good positive predictive value (79.8%). Conclusion The M-ACE BR is a brief and adequate instrument to detect cognitive impairment in older Brazilian adults. However, screening for CIND and for different educational levels should be further explored.

Resumo Antecedentes A idade é o fator de risco mais importante para o desenvolvimento de demência, e a recomendação é que os idosos sejam testados cognitivamente para detectar comprometimento na fase inicial para o tratamento adequado. A demanda pelo atendimento desses idosos é grande, chamando atenção para a necessidade de testes rápidos, com boa acurácia e de simples aplicação para identificar o comprometimento cognitivo. Objetivo Desenvolver e validar a versão brasileira do Mini-Addenbrooke's Cognitive Examination (M-ACE BR) como um teste rápido para rastreio de comprometimento cognitivo em idosos. Métodos A M-ACE BR foi desenvolvida usando análise da escala de Mokken em 352 participantes (cognitivamente saudáveis [CS] = 232, comprometimento cognitivo sem demência [CCSD] = 82; e demência = 38) e validado em uma amostra independente de 117 participantes (CS = 25; CCSD = 88; e demência = 4). Resultados A análise de escala de Mokken derivou 9 itens (orientação espacial, memória anterógrada, memória retrógrada, evocação tardia, reconhecimento [nome e endereço], fluência verbal de letras, repetição de 4 palavras, nomeação de 10 itens e compreensão) com pontuação máxima de 51 pontos e tempo médio de duração de 7 minutos. O escore de corte ≤ 43/51 para CCSD teve sensibilidade de 59,09% e especificidade de 80%. Para um teste de rastreio, em que a sensibilidade é priorizada para investigação posterior, sugerimos utilizar um ponto de corte ≤ 47 (sensibilidade 85,23% e especificidade 24%), mantendo um bom valor preditivo positivo (79,8%). Conclusão A M-ACE BR é um instrumento breve e adequado para detectar comprometimento cognitivo em idosos brasileiros. No entanto, o rastreio para a identificação de CCSD e para diferentes níveis de escolaridade deve ser melhor explorado.

Reabilitação neuropsicológica em caso de adolescente com evento cerebrovascular na primeira infância / Rehabilitación neuropsicológica en caso de adolescente con evento cerebrovascular en la primera infancia / Neuropsychological rehabilitation in case of adolescent with cerebrovascular event in early childhood

RESUMO. O objetivo deste estudo foi apresentar os resultados da reabilitação de um adolescente com dano cerebral precoce no hemisfério direito e cerebelo por acidente vascular cerebral com evolução superior a dez anos e sem histórico de tratamento formal. O método utilizado foi o estudo de caso único, com avaliação pré e pós-aplicação de um programa de reabilitação neuropsicológica. Os resultados obtidos evidenciaram a melhora do funcionamento dos sistemas funcionais para as ações práticas, lúdicas, gráficas e verbais do paciente. Mudanças positivas também foram observadas no aspecto motor, no tônus muscular e no equilíbrio. O paciente mostrou-se mais independente, houve aumento nos interesses, maior nível de regulação, de responsabilidade e participação ativa em sua vida cotidiana. A avaliação neuropsicológica deve considerar a causa psicofisiológica das dificuldades do paciente, juntamente com a atividade orientadora da idade psicológica. Os resultados deste tipo de avaliação permitem a elaboração e aplicação de programas efetivos de reabilitação, inclusive depois de longos períodos sem um tratamento formal. A teoria neuropsicológica de Luria, juntamente com a teoria do desenvolvimento psicológico, representa uma base sólida para a avaliação e organização do processo de reabilitação em casos de pacientes com dano cerebral, mesmo depois de vários anos após o evento traumático.

ABSTRACT. The objective of this study is to present results of the rehabilitation of an individual case of an adolescent patient with early brain damage in right hemisphere and the cerebellum because of a stroke with an evolution of more than ten years without any formal treatment. The method of the individual case study was used in this research, performing a pre-and-post qualitative assessment before and after of the application of the neuropsychological rehabilitation program. The results obtained in the study allowed to point out an improvement in the functioning of functional systems for practical, ludical, graphic and verbal actions of the patient. Positive changes were obtained in the motor sphere, muscle tone and balance. The patient became more independent in his general behavior, his interests were increased, he showed a higher level of regulation, responsibility, and active participation in his day-to-day life. Neuropsychological assessment should consider the psychophysiological cause of the patient's difficulties together with the guiding activity of psychological age. Results of such assessment lead to elaboration and application of effective programs for rehabilitation even after long periods without formal treatment. Luria's neuropsychological theory together with the theory of psychological development represents a solid background for the assessment and organization of the rehabilitation process in cases of patients with brain damage after several years since the event.

Assessment of cognitive function in elderly patients with heart failure

SUMMARY OBJECTIVE: To compare the Mini-Mental State Examination (MMSE) and Montreal Cognitive Assessment (MoCA) tests for the identification of cognitive deficit (CD) in elderly patients with heart failure (HF). METHODS: This was a cross-sectional study with an observational design involving 43 elderly patients with HF of both sexes, treated by the Unified Health System, who were able to understand and follow the study instructions. A sociodemographic and clinical questionnaire and the MMSE and MoCA neurocognitive tests were applied. RESULTS: The mean age of the patients was 67 years; 67.44% were male; 53.49% were white; 58.14% had 1-4 years of schooling; 58.14% had an income of half to one minimum wage; 55.81% were married; 53.49% had a family history of HF; 90.7% denied smoking; 83.72% denied alcohol intake; 65.12% did not practice physical activity; 83.72% were hypertensive; 30.23% were diabetic; 57.89% had LVEF ≥ 50%; 39.53% have NYHA II; and 88.37% did not have a pacemaker. In the identification of CD, the MMSE test detected it in 25.58% of the patients, while the MoCA test identified it in 23.26% (p=0.043). CONCLUSION: It was concluded that the MMSE test performed better than the MoCA test in the identification of CD in elderly patients with HF.

Prospective memory instruments for the assessment of children and adolescents: a systematic review

Abstract Background Prospective memory is the ability to engage in an intention to be performed in the future. The main objective of this study was to identify instruments that assess both time-based and event-based prospective memory in children and adolescents and that have the potential to be clinically applicable. Method Three databases (PubMed, Scopus, and PsycINFO) were searched to identify existing PM measures in original articles published until 2022. Literature searches were conducted using the following terms: (prospective memor* OR memor* for intentions) AND (neuropsychological assessment) AND (test* OR instrument* OR questionnaire* OR task*) AND (psychometric properties) AND (child* OR adolescen*). Relevant studies identified in the reference lists were also included in the review. Results Ten instruments were identified and classified into three categories: (a) test batteries, (b) experimental procedures, and (c) questionnaires. All the instruments identified were described concerning their content and the psychometric properties available. Some of the instruments presented empirical evidence regarding validity and reliability, but no one provided normative data. Conclusion Besides the recent progress regarding studies publishing the development of a variety of novel measures, there are still many limitations surrounding the assessment of PM in the youth population because of the yet incipient psychometric properties presented by the majority of the PM instruments. Recommendations for a goldstandard PM instrument for assessing children and adolescents are provided.

Neuropsychological side effects of anti-epileptic drugs in epilepsy patients: a cross sectional study

Background: Epilepsy is the fourth most common neurological disorder in world. Managing an epilepsy with anti-epileptic drugs (AEDs) either as monotherapy or polytherapy is necessary to reduce the deleterious effect of the disease and to provide neuroprotection. AEDs exert their negative effects on cognition by suppressing neuronal excitability or enhancing inhibitory neurotransmission. These neuropsychological side effects are found to be modest when the drug level is within the therapeutic concentration and used as monotherapy. Objectives were to assess the prevalence of neuropsychological side effects among epilepsy patients who were on antiepileptic drug therapy. Methods: An open label, cross-sectional, clinical study was conducted at a tertiary care hospital, 126 participants were recruited. Participants demographic data, detailed medical and seizure history followed by neuropsychological tests was performed. The prevalence was assessed based on the number of participants scoring <15th percentile in one or more tests. Results: Out of 126 participants who were recruited, 82 participants were on monotherapy and 44 participants were on polytherapy. Levetiracetam was the most commonly prescribed drug as monotherapy, followed by phenytoin, carbamazepine and valproate; whereas in polytherapy levetiracetam, clobazam followed by phenytoin were the commonly prescribed AED. The most common adverse effect was drowsiness, followed by headache, hypersensitivity reaction, giddiness, tremors, anxiety etc. The prevalence of neuropsychological side effects was 77.8%. The prevalence of impairment between monotherapy and polytherapy was statistically insignificant (p=0.727). Conclusions: In this study, levetiracetam was the most commonly prescribed drug and the most common adverse effect was drowsiness due to AEDs. The subgroup analyses between monotherapy and polytherapy did not show any statistically significant neuropsychological impairment when compared based on the gender, age groups, duration of epilepsy with medication and duration of current therapy.

Terapia de remediación cognitiva en bulimia nerviosa: Un estudio de caso / Cognitive remediation therapy in bulimia nervosa: A case study

Resumen El objetivo de este estudio fue realizar una evaluación preliminar de la terapia de remediación cognitiva (TRE) en una paciente con bulimia nerviosa (BN). Bajo un diseño pre-post-tratamiento, la paciente (20 años de edad e índice de masa corporal [IMC] de 22.41) completó cuatro pruebas neuropsicológicas, tres medidas de síntomas de BN y dos de sintomatología psiquiátrica (depresión y ansiedad). Con base a las puntuaciones pre y post TRE fue calculado el cambio clínico objetivo (CCO). Los principales efectos neuropsicológicos se registraron en: flexibilidad de pensamiento, proceso visocontructivo, coherencia central y planificación (CCO = 0.39-0.99). También se identificaron cambios relevantes en las medidas de sintomatología psiquiátrica y de BN (CCO = 0.53-0.88), no así en el IMC. Este estudio suma evidencias respecto a la utilidad de la CRT en el tratamiento multidisciplinario, ya no solo de la anorexia nerviosa, sino que extiende su aplicabilidad a la BN.

Abstract The aim of this study was to perform a preliminary evaluation of cognitive remediation therapy (CRT) in a patient with bulimia nervosa (BN). The participant was 20 years old with a 22.41kg/m2 body mass index (BMI). Under a pre-post treatment design, the patient was administered four neuropsychological tests, three measures of BN symptoms and two of psychiatric symptomatology (depression and anxiety). Based on the pre and post CRT scores, the objective clinical change (OCC) was calculated. The main neuropsychological effects were observed in cognitive flexibility, visoconstructive processing (memory and central coherence) and working memory (OCC = 0,39-0,99). Relevant changes were also identified in the measures of psychiatric symptomatology and BN (OCC = 0,53-0,88), with no change in BMI. This study adds evidence regarding the usefulness of CRT in the multidisciplinary treatment not only of anorexia nervosa, but also extends its applicability to another eating disorder, BN.

Perfil cognitivo en el Mareo Perceptual Postural Persistente: Implicancias sobre su fisiopatología como disfunción cognitiva viso-vestibular superior / Cognitive profile in Persistent Postural Perceptual Dizziness: Implications on its pathophysiology as a superior visio-vestibular cognitive dysfunction

Introducción: El mareo perceptual postural persistente (MPPP) es, probablemente, la causa más prevalente de mareo crónico. Sin embargo, su fisiopatología es aún motivo de duda y debate. En el presente artículo, proponemos que el MPPP se caracteriza por disfunciones cognitivas de orden superior, al punto de diferenciarse en estas dimensiones de controles sanos y pacientes con patologías vestibulares no-MPPP. Objetivo: Determinar si pacientes con MPPP presentan alteraciones discriminantes respecto a grupos controles, en ámbitos de atención, memoria de trabajo visoespacial, planificación espacial, funciones ejecutivas y rendimiento cognitivo global. Material y Método: Estudio descriptivo transversal con sujetos de entre 18 y 65 años, reclutados de una unidad de otoneurología ambulatoria. Se aplicaron pruebas Montreal Cognitive Assessment (MoCA), tarea de retención de dígitos, Trail Making Test, Corsi Block-Tapping Task y Torre de Londres. Resultados: 30 pacientes fueron categorizados en tres grupos: grupo MPPP (n = 14), grupo vestibular no-MPPP (n = 11) y grupo control (n = 5). El grupo MPPP exhibió un rendimiento significativamente inferior en pruebas de planificación, velocidad de procesamiento y funciones ejecutivas en ámbitos visoespaciales, mientras que en atención y memoria visoespacial no hubo diferencias entre grupos. Conclusión: El MPPP podría caracterizarse por una disfunción de procesos cognitivos superiores de construcción espacial de mayor complejidad, respetando funciones visoespaciales de menor orden como la memoria de trabajo. Estos hallazgos ofrecen nuevas luces para comprender la fisiopatología del MPPP y sus implicancias clínicas.

Introduction: Persistent postural-perceptual dizziness (PPPD) is probably the most prevalent cause of chronic dizziness. However, its pathophysiology is still a matter of uncertainty and debate. In this article, we propose that PPPD is characterized by higher-order cognitive dysfunctions, to the point of differentiating it from healthy controls and patients with non-PPPD vestibular pathologies. Aim: To determine whether patients with PPPD exhibit discriminant alterations compared to control groups in the areas of attention, visuospatial working memory, spatial planning, executive functions, and global cognitive performance. Materials and Methods: A cross-sectional descriptive study was conducted with subjects between the ages of 18 and 65 years, recruited from an outpatient otoneurology unit. Tests included the Montreal Cognitive Assessment (MoCA), digit retention task, Trail Making Test, Corsi Block-Tapping Task, and the Tower of London. Results: 30 patients were categorized into three groups: PPPD group (n = 14), non-PPPD vestibular group (n = 11), and control group (n = 5). The PPPD group showed significantly lower performance on tests of planning, processing speed, and executive function in visuospatial domains, while there were no differences between groups in attention and visuospatial memory. Conclusion: PPPD may be characterized by dysfunction of higher-order cognitive processes related to spatial construction of greater complexity, while sparing lower-order visuospatial functions such as working memory. These findings offer new insights into the pathophysiology of PPPD and its clinical implications.

Diagnóstico de la variante conductual de demencia frontotemporal basado en estadios clínicos adaptado para países con baja educación: el caso de Perú

Demencia frontotemporal (DFT) es una condición neurodegenerativa escasamente reconocida en personas menores a 65 años de edad. El diagnóstico de DFT variante conductual (DFTvc) se basa en una entrevista clínica comprehensiva, complementada por una evaluación multidimensional (neurológica, cognitiva, neuropsiquiátrica, de biomarcadores e imágenes cerebrales) adaptada y validada a la población a estudiar; sin embargo, a pesar del incremento de su prevalencia en Latinoamérica y el Caribe, existe necesidad de herramientas estandarizadas y un consenso para el diagnóstico de DFTvc. El artículo intenta realizar una aproximación del enfoque de diagnóstico de DFTvc en escenario de paises con bajos y medianos ingresos, como el Perú.

Frontotemporal dementia (FTD) is a widely recognized neurodegenerative condition in people under 65 years old. The diagnosis of behavioral variant FTD (bvFTD) is based on a comprehensive clinical assessment, complemented by a multidimensional assessment (neurological, cognitive, neuropsychiatric, biomarker and brain imaging) adapted and validated to the population to be studied; however, despite its increasing prevalence in Latin America and the Caribbean, there is a need for standardized tools and consensus for the bvFTD diagnosis. The manuscript attempts to approximate the approach for the diagnosis of bvFTD in the setting of low and middle-income countries, including Peru.

Neuropsychology of epilepsy surgery and theory-based practice: an opinion review / Neuropsicologia da cirurgia de epilepsia e prática teórica: uma revisão de opinião

Abstract The present review attempts to discuss how some of the central concepts from the Lurian corpus of theories are relevant to the modern neuropsychology of epilepsy and epilepsy surgery. Through the lenses of the main Lurian concepts (such as the qualitative syndrome analysis), we discuss the barriers to clinical reasoning imposed by quadrant-based views of the brain, or even atheoretical, statistically-based and data-driven approaches. We further advice towards a systemic view inspired by Luria's clinical work and theorizing, given their importance towards our clinical practice, by contrasting it to the modular views when appropriate. Luria provided theory-guided methods of assessment and rehabilitation of higher cortical functions. Although his work did not specifically address epilepsy, his theory and clinical approaches actually apply to the whole neuropathology spectrum and accounting for the whole panorama of neurocognition. This holistic and systemic approach to the brain is consistent with the network approach of the neuroimaging era. As to epilepsy, the logic of cognitive functions organized into complex functional systems, contrary to modular views of the brain, heralds current knowledge of epilepsy as a network disease, as well as the concept of the functional deficit zone.

Resumo A presente revisão tenta discutir como alguns dos conceitos centrais do corpus de teorias lurianas são relevantes para a moderna neuropsicologia da epilepsia e cirurgia da epilepsia. Através das lentes dos principais conceitos lurianos (como a análise qualitativa de síndromes), discutimos as barreiras ao raciocínio clínico impostas por visões do cérebro baseadas em quadrantes, ou mesmo abordagens ateóricas, baseadas em estatísticas e orientadas por dados. Aconselhamos ainda uma visão sistêmica inspirada na clínica e na teorização de Luria, dada sua importância para nossa prática clínica, contrastando-a com as visões modulares quando apropriado. Luria forneceu métodos teóricos de avaliação e reabilitação de funções corticais superiores. Embora seu trabalho não abordasse especificamente a epilepsia, sua teoria e abordagens clínicas na verdade se aplicam a todo o espectro da neuropatologia e respondem por todo o panorama da neurocognição. Essa abordagem holística e sistêmica do cérebro é consistente com a abordagem de rede da era da neuroimagem. Quanto à epilepsia, a lógica das funções cognitivas organizadas em sistemas funcionais complexos, ao contrário das visões modulares do cérebro, anuncia o conhecimento atual da epilepsia como uma doença em rede, bem como o conceito de zona de déficit funcional.

Neuropsychological and quality of life outcomes in PKU patients: expert recommendations of assessment tools in Brazil / Desfechos neuropsicológicos e de qualidade de vida em pacientes com PKU: recomendações de especialistas sobre ferramentas de avaliação no Brasil

Abstract Background Phenylketonuria (PKU) is an inborn error of metabolism caused by deficient activity of phenylalanine hydroxylase. In Brazil, the National Neonatal Screening Program enables early treatment of patients with PKU, which prevents them from developing severe neurological damage and mental disabilities. However, between 20 and 30% of early-treated patients with PKU present focal cognitive deficits, including deficits in working memory, processing speed, and psychiatric symptoms such as anxiety, depression, and attention deficit hyperactivity disorder (ADHD). Therefore, age-specific neuropsychiatric and cognitive tests are important components of PKU patient care. To date, there are no officially approved guidelines or recommendations of tools in Portuguese validated for use in Brazil that could be applied to assess these parameters in patients with PKU. Objective To recommend tools validated for use in Brazil that can be used in daily clinical practice to assess quality of life and neuropsychological outcomes in patients with PKU. Methods Six Brazilian experts discussed about eligible tools based on their clinical experience, the feasibility of their use in clinical routines, and their availability in public health services. Before the meeting, an independent review of the literature was conducted to identify the currently validated tools in Brazil, using the MEDLINE and SciELO databases. Results The experts recommended nine tools to assess quality of life (Peds-QL, SF-36 or WHOQOL-bref), executive function (BRIEF or Bayley-III), IQ (SONR 2½-7[a] or WASI) and ADHD (MTA-SNAP-IV and ASRS). Conclusions These instruments may be easily incorporated into clinical practice and improve the quality of multidisciplinary care of patients with PKU.

Resumo Antecedentes A fenilcetonúria (PKU) é um erro inato do metabolismo causado pela atividade deficiente da fenilalanina hidroxilase. No Brasil, o Programa Nacional de Triagem Neonatal permite o tratamento precoce de pacientes com PKU, o que os impede de desenvolver danos neurológicos e deficiências intelectuais graves. No entanto, já foi descrito que de 20 a 30% dos pacientes tratados precocemente com PKU apresentam déficits cognitivos focais, incluindo déficits na memória de trabalho, velocidade de processamento e sintomas psiquiátricos como ansiedade, depressão e Transtorno de Déficit de Atenção e Hiperatividade (TDAH). Neste sentido, testes neuropsiquiátricos e cognitivos são componentes importantes no cuidado destes pacientes. Atualmente, não existe um compêndio científico ou recomendações de ferramentas validadas em português para avaliar a saúde mental em pacientes brasileiros com PKU. Objetivo Recomendar ferramentas validadas localmente para avaliar a qualidade de vida e aspectos neuropsicológicos de pacientes com PKU. Métodos Seis especialistas brasileiros discutiram as ferramentas mais apropriadas com base em suas experiências clínicas, a viabilidade de realizar as avaliações na rotina clínica, e o acesso às ferramentas na saúde pública. Antes da reunião, foi realizada uma revisão independente da literatura para identificar as ferramentas validadas no Brasil, utilizando as bases de dados MEDLINE e Scielo. Resultados Os especialistas recomendaram nove ferramentas para avaliar a qualidade de vida (Peds-QL, SF-36 ou WHOQOL-bref), função executiva (BRIEF ou Bayley-III), QI (SONR 2½-7[a] ou WASI) e TDAH (MTA-SNAP-IV e ASRS). Conclusões Estes instrumentos podem ser facilmente incorporados na prática clínica e melhorar a qualidade dos cuidados multidisciplinares dos pacientes com PKU.

Evaluación del neurodesarrollo en niños con exposición intrauterina al virus del Zika: estudio observacional transversal / Developmental assessment of children with intrauterine exposure to Zika virus: cross-sectional observational study

El virus del Zika produce desenlaces adversos para el desarrollo del sistema nervioso. Este estudio describe el neurodesarrollo cognitivo, adaptativo, comunicativo, social y motor de niños expuestos intrauterinamente al virus del Zika y hace una evaluación del neurodesarrollo con la escala de Battelle a los tres años después del nacimiento. Participaron 30 niños con una media de edad al momento de la evaluación de 37,5 (RIC: 35,7-39,2) meses. Se halló una edad equivalente en meses en las áreas: motora 25,8 (DE: 7,8), adaptativa 26,7 (DE: 5,8), comunicativa 30,2 (DE: 6,9), personal social 33,5 (DE: 8,3) y cognitiva 35,6 (DE: 5,9). Los niños presentaron retraso en el desarrollo para la edad cronológica, 25 niños presentaban retraso en una de las cinco áreas evaluadas. Una alta proporción de niños expuestos al virus del Zika durante la gestación presentaron retraso en el desarrollo, principalmente en el dominio adaptativo y motor.

Zika virus infection affects the development of the nervous system. This study describes the cognitive, adaptative, communicative, social and motor neurodevelopment of children exposed to Zika virus in utero. We used the Batelle scale to assess neurodevelopment three years after birth. Thirty children were included, who had a mean age at evaluation of 37.5 (IQR: 35.7-39.2) months. We found the following equivalent ages in months for each area: motor 25.8 (SD: 7.8), adaptive 26.7 (SD: 5.8), communicative 30.2 (SD: 6.9), social personal 33.5 (SD: 8.3) and cognitive 35.6 (SD: 5.9). Children showed development delay for their chronological age, 25 children were delayed in one of the five areas assessed. A high rate of children exposed to Zika virus during gestation presented delayed developmental age, mainly regarding the adaptive and motor areas.

Cognitive impairment in multiple sclerosis: "classic" knowledge and recent acquisitions / Deficiência cognitiva na esclerose múltipla: conhecimentos "clássicos" e aquisições recentes

Abstract Multiple sclerosis (MS) is a central nervous system (CNS) disease characterized by inflammation, axonal demyelination, and neurodegeneration, which can have a strong impact on all aspects of the life of the patient. Multiple sclerosis causes motor, sensory, cerebellar, and autonomic dysfunctions, as well as cognitive and psychoemotional impairment. The most frequently compromised cognitive domains are complex attention/information processing, memory, executive and visuospatial functions. Recently, alterations have also been evidenced in complex cognitive functions, such as social cognition, moral judgment, and decision-making. Cognitive impairment is characterized by high variability and can affect work skills, social interactions, coping strategies and more generally the quality of life of patients and their families. With the use of sensitive and easy-to-administer test batteries, an increasingly accurate and early diagnosis is feasible: this allows to determine the effectiveness of possible preventive measures, to predict the future progression of the disease and to improve the quality of life of patients. There is currently limited evidence regarding the efficacy, on cognitive impairment, of disease-modifying therapies. The most promising approach, which has received strong empirical support, is cognitive rehabilitation.

Resumo A esclerose múltipla (EM) é uma doença do sistema nervoso central (SNC) caracterizada por inflamação, desmielinização axonal e neurodegeneração, que pode ter um forte impacto em todos os aspectos da vida dos pacientes. A EM causa disfunções motoras, sensoriais, cerebelares, autonômicas, comprometimento cognitivo e déficits psicoemocionais. Os domínios cognitivos mais frequentemente comprometidos são a atenção complexa/processamento da informação, memória, funções executivas e habilidades visuais-espaciais. Recentemente, também foram evidenciadas alterações em funções cognitivas complexas, como cognição social, julgamento moral e tomada de decisão. O comprometimento cognitivo é caracterizado por alta variabilidade e pode afetar as habilidades laborais, as interações sociais, as estratégias de enfrentamento e, de forma mais geral, a qualidade de vida dos pacientes e de seus familiares. Com o uso de baterias de testes sensíveis e fáceis de administrar, é viável um diagnóstico cada vez mais preciso e precoce: isso permite determinar a eficácia de possíveis medidas preventivas, prever a progressão futura da doença e melhorar a qualidade de vida dos pacientes. Atualmente, há evidências limitadas sobre a eficácia, no comprometimento cognitivo, de terapias modificadoras da doença. A abordagem mais promissora, que tem recebido forte apoio empírico, é a reabilitação cognitiva.

Introducción: la esclerosis múltiple (EM), enfermedad crónica del sistema nervioso (SNC), compromete significativamente la cognición. Su prevalencia en Paraguay es 9,2/100.000 habitantes, 72% con recaída remisión (EMRR) e incidencia de 2-3mujeres/hombre, afecta más a personas en edad productiva, con altos costos económicos y afectivos. Objetivos: caracterizar al paciente con EMRR, evaluar sus funciones ejecutivas (FEs) con BaNFE-2; establecer valores de corte ajustados al país. Metodología: con fundamento en teoría de la neurociencia cognitiva, diseño no experimental, cuantitativo, descriptivo, empírico, retrospectivo y transversal; técnica psicométrica y entrevista neuropsicológica en una muestra por conveniencia de 40 pacientes, 82,5% mujeres y edad 25-55 años (37,78±7,89). Resultados: se reportaron datos demográficos y clínicos, se caracterizaron las escalas de BaNFE-2 cuya consistencia interna resultó significativa. Se obtuvo 52,5% de alteración en la escala prefrontal y 42,5% en FEs; relaciones significativas con escolaridad, discapacidad física (DF), cantidad de brotes y deterioro cognitivo (DC); diferencias significativas por sexo, escolaridad, DF y DC. Se calcularon puntuaciones tipificadas por escolaridad, z<-1 establece el corte entre normalidad y alteración. Conclusión: las pruebas de BaNFE-2 perfilan la afectación del tiempo de ejecución, atención, memoria de trabajo y FEs. Este estudio aporta baremos ajustados al país y abre una novedosa línea de investigación aplicando BaNFE-2 en EM.

Introduction: Multiple sclerosis (MS) is a chronic, neurodegenerative, inflammatory disease of the central nervous system (CNS) that significantly compromises cognitive functions. In Paraguay, it occurs with a prevalence of 9.2/100,000 inhabitants, 72% in the clinical form of relapsing remission (RRMS) and an incidence of 2 to 3 women/men, affecting more people of productive age with high economic and emotional costs. Objectives: To characterize the Paraguayan patient with RRMS, to assess the state of their executive functions (EFs) with the BaNFE-2 battery, and to establish cut-off values adjusted to the country. Methods: Research based on the theory of cognitive neuroscience of non-experimental, quantitative and descriptive design for analytical purposes. It is empirical, retrospective and cross-sectional. The psychometric technique and neuropsychological interview were used in a convenience sample of 40 patients aged 25 to 55 (37.78 ± 7.89) and 82.5% women. Results: Demographic and clinical data of the participants were reported. The BaNFE-2 coded and normalized scales were statistically characterized, the internal consistency of which was significant. 52.5% of the alteration was obtained in the anterior prefrontal scale and 42.5% in FEs; there are significant relationships with schooling, physical disability (PD), number of outbreaks and cognitive impairment (CI); there were also significant differences by sex, education, PD and CI. Standardized scores adjusted for schooling were calculated such that z<-1 establishes the cutoff between normality and abnormality. Conclusion: BaNFE-2 battery tests profile the affectation of execution time, attention, working memory, and FEs. This study provides the adjusted scales for the country and opens a new line of research applying the BaNFE-2 battery in people with MS.

Impacto de la Terapia Electroconvulsiva en el Funcionamiento de la Memoria en Pacientes con Depresión

Introducción: La seguridad de la terapia electroconvulsiva ha mejorado mucho en las últimas décadas, lo que hace que los efectos potencialmente adversos en la memoria y otras funciones neurocognitivas sean el principal aspecto clínico de preocupación en el presente. En Colombia, la población general y los profesionales de la salud (incluso algunos psiquiatras) parecen tener opiniones mayoritariamente negativas sobre el tratamiento electroconvulsivo, pero quizá esto podría reconsiderarse si se brinda más información; por lo tanto, el objetivo del presente estudio es evaluar los cambios en la memoria y la gravedad de los síntomas en un grupo de pacientes con depresión grave antes y después de la terapia electroconvulsiva. Métodos: Se incluyó a 23 pacientes con edades comprendidas entre los 23 y los 70 anos del Servicio de Terapia Electroconvulsiva de la Clínica San Juan de Dios (Manizales, Colombia) para evaluar el efecto de esta terapia en la memoria de pacientes con depresión grave. Los síntomas depresivos y la memoria se evaluaron con la escala de depresión de Hamilton (HAMD) y la prueba de aprendizaje auditivo verbal de Rey (RAVLT) respectivamente. Se evaluó a los participantes antes de la sesión inicial de la serie de terapia electroconvulsiva (0-1 día) y 2 días después de su último tratamiento. Resultados: La terapia electroconvulsiva resultó en una mejora significativa en la puntuación de depresión. No hubo diferencias significativas en las puntuaciones de las 5 pruebas de aprendizaje, recuerdo retardado, aprendizaje y olvido desde antes del tratamiento hasta después de este. Se encontraron diferencias significativas antes y después del tratamiento en la prueba de reconocimiento retardado. Conclusiones: Los problemas de memoria pueden evaluarse y caracterizarse de manera práctica tras la terapia electroconvulsiva. La evaluación cognitiva antes y después de la terapia electroconvulsiva es un procedimiento viable y útil. En general, el rendimiento de la memoria no empeora después de la terapia electroconvulsiva en pacientes con depresión. Solo el reconocimiento retardado se ve afectado unos días después, particularmente en pacientes con bajo nivel educativo y colocación de electrodos bitemporales (BT).

Introduction: The safety of electroconvulsive therapy has improved greatly over the last decades, making the potentially adverse effects on memory and other neurocognitive functions the main clinical aspect of concern in the present. In Colombia, the general population and healthcare professionals (even some psychiatrists) seem to have mostly negative opinions towards electroconvulsive therapy treatment, but maybe this could be reconsidered if more information is provided; therefore, the aim of the present study was to evaluate the changes in memory and the severity of the symptoms in a group of patients with severe depression before and after electroconvulsive therapy. Methods: Twenty-three patients ranging in age from 23 to 70 years from the electroconvulsive therapy service at the San Juan de Dios Clinic (Manizales, Colombia) were recruited in order to assess the effect of electroconvulsive therapy on memory in patients with severe depression. Depressive symptoms and memory were assessed with the Hamilton Depression Scale (HAMD) and Rey Auditory Verbal Learning Test (RAVLT), respectively. The assessment was administered to participants before the initial treatment of electroconvulsive therapy series (0-1 day) and 2 days after their last treatment. Results: Electroconvulsive therapy resulted in significant improvement in the rating of depression. There were no significant differences in the five learning trials, delayed recall, learning and forgetting scores from pre-treatment to post-treatment. Significant pre-treatment/post-treatment differences were found in the delayed recognition trial. Conclusions: Pre- and post- electroconvulsive therapy cognitive assessment is a feasible and useful procedure. In general, memory performance does not worsen after electroconvulsive therapy in patients with depression. Only delayed recognition is affected a few days following electroconvulsive therapy, particularly in patients with low educational level and bitemporal (BT) electrode placement.

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.

Elderly people with human T-cell leukemia virus type 1-associated myelopathy present an early impairment in cognitive skills / Idosos com mielopatia associada ao vírus da leucemia de células T humanas tipo 1apresentam comprometimento precoce em habilidades cognitivas

Abstract Background Cerebral changes occur in individuals with human T-cell leukemia virus type 1 (HTLV-1 )-associated myelopathy (HAM) and seem to predominate in subcortical areas. Little is known about the cognitive decline in the elderly living with HTLV-1. Objective To evaluate the cognitive aging of individuals infected with HTLV-1 aged ≥ 50 years. Methods This is a cross-sectional study of former blood donors infected with HTLV-1 who have been followed in the cohort of the Interdisciplinary Research Group on HTLV-1 since 1997. The groups of study consisted of 79 HTLV-1 infected individuals aged ≥ 50 years, with 41 of them presenting symptomatic HAM and 38 being asymptomatic carriers, and 59 seronegative individuals (controls) aged ≥ 60 years. All were submitted to the P300 electrophysiological test and neuropsychological tests. Results Individuals with HAM presented delayed P300 latency in relation to the other groups, and this latency delay increased progressively with aging. The performance of this group in the neuropsychological tests was also the worst. The HTLV-1- asymptomatic group performance was similar to that of the control group. Conclusions Individuals with HAM presented cognitive decline that progressed with aging and, although HTLV-1-asymptomatic carriers appear to present cognitive aging similar to that of healthy elderly people, concern about a subclinical cognitive impairment is warranted in this population.

Resumo Antecedentes Alterações cerebrais ocorrem em indivíduos com mielopatia associada ao vírus da leucemia de células T humanas tipo 1 (HTLV-1) (HAM) e parecem predominar em áreas subcorticais. Pouco se sabe sobre o declínio cognitivo em idosos vivendo com HTLV-1. Objetivo Avaliar o envelhecimento cognitivo de indivíduos infectados pelo HTLV-1 com idade ≥ 50 anos. Métodos Trata-se de um estudo transversal com ex-doadores de sangue infectados pelo HTLV-1 acompanhados na coorte do Grupo Interdisciplinar de Pesquisa em HTLV-1 há 20 anos. Os grupos de estudo foram compostos por 79 indivíduos infectados pelo HTLV-1 com idade ≥ 50 anos, sendo que 41 apresentavam HAM e 38 eram portadores assintomáticos, e 59 indivíduos soronegativos (controles) com idade ≥ 60 anos. Todos foram submetidos ao teste eletrofisiológico P300 e testes neuropsicológicos. Resultados Indivíduos com HAM apresentaram atraso na latência do P300 em relação aos demais grupos, e esse atraso de latência aumentou progressivamente com o envelhecimento. O desempenho desse grupo nos testes neuropsicológicos também foi o pior. O desempenho do grupo HTLV-1- assintomático foi semelhante ao do grupo controle. Conclusão Indivíduos com HAM apresentaram declínio cognitivo que progrediu com o envelhecimento e, embora os portadores assintomáticos do HTLV-1 pareçam apresentar envelhecimento cognitivo semelhante ao dos idosos saudáveis, justificase a preocupação com um comprometimento cognitivo subclínico nessa população.
