Perfil neuropsicológico e comportamental de crianças com doença falciforme / Neuropsychological and behavioral profile of children with sickle cell disease.

Abreu, Katiusha de Cerqueira 24 May 2013 (has links)
A Doença Falciforme (DF) constitui patologia hematológica que leva a diversas complicações sistêmicas, sobretudo sequelas neurológicas e déficits cognitivos. Algumas pesquisas têm correlacionado exames de Imagem por Ressonância Magnética (IRM) e Doppler Transcraniano (DTC) com avaliações neuropsicológicas em crianças com DF, sinalizando prejuízos cognitivos específicos e déficit intelectual geral que tendem a predispor ao baixo desempenho acadêmico e maior índice de retenção escolar. No Brasil há alta prevalência dessa doença, tornando-se importante a realização de estudos em crianças, visto que o diagnóstico precoce de dificuldades neuropsicológicas possibilita intervenções de caráter preventivo e formulação de programas de reabilitação em quadros de disfunção cerebral. Objetivo: Caracterizar o desempenho neuropsicológico e comportamental de crianças com DF, na faixa de 7 a 12 anos. Pretende-se avaliar e descrever as principais funções cognitivas (atenção/função executiva, aprendizagem e memória, linguagem, processamento visoespacial, função sensoriomotora) e possíveis dificuldades comportamentais e correlacionar esses resultados com variáveis sociodemográficas e clínicas. Método: Participaram dessa pesquisa 60 crianças, compondo dois grupos de 30 voluntários (clínico e controle), pareados em função do sexo, origem escolar e idade. Foram utilizados como instrumentos de avaliação psicológica: QI Estimado do WISC III e Matrizes Progressivas Coloridas de Raven, NEPSY II - Avaliação Neuropsicológica do Desenvolvimento e o Child Behavior Checklist (CBCL). O Grupo Clínico realizou exame neurológico clínico, IRM, DTC e hemograma. Resultados: As crianças com DF apresentaram significativos prejuízos no desempenho intelectual geral e déficits em diversos domínios neuropsicológicos específicos, principalmente função executiva, linguagem, memória visoespacial e habilidade visoespacial, comparativamente ao Grupo Controle. Nos exames médicos do Grupo Clínico, todos DTC foram considerados dentro da faixa normal e na IRM houve prevalência de 24% da amostra com infarto cerebral silencioso (ICS). O comprometimento na capacidade intelectual geral, na memória narrativa e visoespacial e no processamento fonológico foram mais significativos no Grupo com ICS. Essas diversas alterações neuropsicológicas no Grupo Clínico tendem a predispor a dificuldades no desempenho acadêmico e maior repetência escolar. Além disso, houve evidências de significativos índices de problemas comportamentais e emocionais nas crianças com DF. Observou-se declínio cognitivo em distintas funções neuropsicológicas com o aumento da idade cronológica, porém não foi evidenciada influência das variáveis como sexo, tipo genético, tipo de medicação e índices do hemograma nos resultados neuropsicológicos e comportamentais das crianças. Esses resultados trazem relevantes implicações para o tratamento dos portadores de DF, pois ressaltam a importância do acompanhamento multiprofissional e a necessidade da realização da avaliação neuropsicológica e de adequada intervenção em centros de reabilitação, com objetivo de promover melhor qualidade de vida e condições favoráveis ao desenvolvimento dessas crianças (CAPES e FAPESP). / The Sickle Cell Disease (SCD) is a haematological pathology that leads to several systemic complications, especially neurological sequelae and cognitive deficits. Some studies have correlated exams of Magnetic Resonance Imaging (MRI) and Transcranial Doppler (TCD) ultrasonography with neuropsychological assessment in children with SCD, indicating specific cognitive impairments and general intellectual deficit that tend to predispose to poor academic performance and higher rates of school retention. In Brazil there is a high prevalence of this disease, making it important to conduct studies in children, since early diagnosis of neuropsychological difficulties enables preventive interventions and formulation of rehabilitation programs in frames of brain dysfunction. Objective: To characterize the behavioral and neuropsychological performance of children with SCD, in the range 7-12 years. Aims to assess and describe the main cognitive functions (attention / executive function, learning and memory, language, visuospatial processing, sensorimotor function) and possible behavioral difficulties and to correlate these results with clinical and sociodemographic variables. Method: In this study, participated 60 children, also composing two groups of 30 volunteers (clinical and control) matched for sex, age and school origin. Were used as instruments of psychological assessment: IQ Estimate the WISC III and Raven\'s Coloured Progressive Matrices, NEPSY II - Neuropsychological Development and Child Behavior Checklist (CBCL). The Clinical Group conducted clinical neurological examination, MRI, TCD and blood count. Results: Children with SCD in neuropsychological profile showed impairments in general intellectual functioning and deficits in several specific neuropsychological domains, especially executive function, language, visuospatial memory and visuospatial skills compared to the Control Group. In medical examinationof Clinical Group, all TCD were considered within the normal range and prevalence of MRI was 24% of the sample with silent cerebral infarction (ICS). The impairment in general intellectual ability, narrative and visuospatial memory and phonological processing were more significant in the Group with ICS. These diverse neuropsychological deficits in Clinical Group tend to predispose to difficulties in academic performance and increased school failure. Furthermore, there was evidence of significant levels of behavioral and emotional problems in children with SCD. Observed cognitive decline in various neuropsychological functions with increasing chronologic age, but it has not shown the influence of variables such as gender,iables such as gender, genetic type, type of medication and the blood count indices in neuropsychological and behavioral outcomes in these children. These results provide relevant implications for the treatment of patients with SCD, because it emphasizes the importance of multidisciplinary monitoring and the need to conduct neuropsychological assessment and adequate intervention in rehabilitation centers with the aim of promoting a better quality of life and favorable conditions for the development of these children.

Trata-se de estudo correlacional, transversal, de natureza predominantemente quantitativa. Os instrumentos de coleta de dados s?o os subtestes do dom?nio ?Aten??o/ Fun??es Executivas? do NEPSY-II. Foram avaliadas 80 crian?as entre 5 e 8 anos de idade, de ambos os sexo, estudantes de escolas p?blicas e particulares da cidade de Natal - RN. A amostra foi segmentada em intervalos de seis meses para posterior an?lise das estrat?gias e tipos de erros. Foram realizadas an?lises de vari?ncia (multivariada e univariada), testes post hoc de Tukey e Games-Howell para verificar o efeito da idade sobre o desempenho nos testes. Correla??es posteriores indicaram a for?a e a dire??o do relacionamento entre as vari?veis. Identificaram-se dois picos de desenvolvimento no intervalo de seis meses adotado para as habilidades de aten??o seletiva e controle inibit?rio. Os resultados indicam que n?o h? influencia significativa do sexo e tipo de escola sobre o desempenho da amostra. O desempenho dos pr?-escolares (5 e 6 anos) foi inferior aos demais subgrupos na maioria dos testes. Destaca-se o papel do discurso de autoregula??o entre os pr?-escolares durante as atividades de maior demanda executiva e o recurso da abstra??o como estrat?gia de resolu??o entre os mais velhos. Identificaram-se trajet?rias de desenvolvimento semelhantes entre as habilidades de aten??o seletiva e controle inibit?rio. De maneira geral, h? decr?scimo no n?mero de erros e aumento de acertos com a progress?o da idade. Pesquisas longitudinais futuras podem ampliar a faixa et?ria abarcada neste estudo, investigando o curso desenvolvimental das habilidades executivas. / This study aimed to establish the developmental profile of executives components in typical child development. This is a correlational cross-sectional study of predominantly quantitative. The instruments for data collection are the subtests included in the NEPSY-II Attention and Executive Functioning domain. Eighty children between 5 and 8 years of age, of both genders, students from public and private schools in the city of Natal were evaluated. The sample was divided into six-month intervals for subsequent analysis of strategies and types of errors. Analysis of variance (univariate and multivariate) and Tukey and Games-Howell post hoc tests were conducted to verify the effect of age on test performance. Subsequent correlations indicate the strength and direction of the relationship between variables. Were identified two peaks of development in the six-month interval adopted for the skills of selective attention and inhibitory control. The results indicate that there?s no significant influence of sex and type of school on the performance of the sample. The performance of preschool children (5 and 6 years) was lower than the other subgroups in most tests. Highlights the role of autoregulation discourse among preschool children during activities of greater executive demand and the abstraction resource as a resolution strategy between the older. Were identified similar development trajectories among selective attention abilities and inhibitory control. In general, there is a decrease in the number of mistakes and increase of success with the age progression. Future longitudinal research can extend the age range encompassed in this study, investigating the developmental course of executive abilities.

AN INVESTIGATION OF THE CONCURRENT CRITERION-RELATED VALIDITY OF THE COMPREHENSIVE EXECUTIVE FUNCTION INVENTORY (CEFI) - SELF-REPORT MEASURE

Seiple, Deborah Ann January 2016 (has links)
Executive function (EF) processes are crucial for meeting demands in the classroom. Because of this impact on schooling, it is important to have tools that accurately measure EF in order to facilitate the identification of student needs and the development of interventions. This project assessed the concurrent, criterion-related validity of one of these tools, the Comprehensive Executive Functioning Inventory, Self-Report (CEFI-SR; Naglieri & Goldstein, 2013). This study correlated adolescents’ reports about their own behavior to scores derived from a direct measure of executive function to determine if teens were able to accurately rate their own EF abilities, indicating that the CEFI-SR had concurrent validity. Seventy-nine seventh and eighth grade students from a suburban middle school were recruited. The average age for the sample was 13 years and 10 months old, and 62% of the sample consisted of female students. Participants completed the CEFI-SR in small groups, and then, the lead examiner returned to the school to complete direct one-on-one testing with each student. Data were analyzed using Pearson product-moment correlations and t-tests. The t-tests were used to determine if significant differences between groups were present. Results from the t-tests indicated that there were no significant differences in performance across genders or grades. Additionally, no significant correlations were found between the rating scale scores and the results of the direct testing. These findings do not support the hypotheses that the CEFI-SR subscales would have moderate correlations with the direct testing scores from the NEPSY-II, indicating that the two measures may not be measuring the same constructs. / School Psychology
