Language impairment in euthymic, elderly patients with bipolar disorder but no dementia

Background: Neurocognitive impairment is known to occur in euthymic bipolar patients, but language alterations have not been thoroughly investigated. The aim of this study is to examine the performance in language tests of a sample of elderly patients with bipolar disorder. Methods: We studied 33 eurthymic elderly patients with bipolar disorder but no dementia and 33 healthy individuals, matched for age and education, who were compared in terms of their CAMCOG global score and its subitems. Results: The scores obtained in language-related abilities for patients and controls, respectively, were: language (total): 27.3 (1) and 28.5 (1), p < 0.0001)comprehension: 8.6 (0.5) and 8.9 (0.3), p = 0.006; production: 18.7 (1) and 19.6 (0.9), p = < 0.0001; abstraction: 6.8 (1.1) and 7.3 (0.7), p = 0.016; verbal fluency: 16.3 (4.3) and 19.6 (4.1), p = 0.003. Conclusion: A mild but significant impairment in language-related ability scores was detected when comparing patients and controls.

Individual differences in speech and language ability profiles in areas of high deprivation

Speech and language ability is not a unitary concept; rather, it is made up of multiple abilities such as grammar, articulation and vocabulary. Young children from socio-economically deprived areas are more likely to experience language difficulties than those living in more affluent areas. However, less is known about individual differences in language difficulties amongst young children from socio-economically deprived backgrounds. The present research examined 172 four-year-old children from socio-economically deprived areas on standardised measures of core language, receptive vocabulary, articulation, information conveyed and grammar. Of the total sample, 26% had difficulty in at least one area of language. While most children with speech and language difficulty had generally low performance in all areas, around one in 10 displayed more uneven language abilities. For example, some children had generally good speech and language ability, but had specific difficulty with grammar. In such cases their difficulty is masked somewhat by good overall performance on language tests but they could still benefit from intervention in a specific area. The analysis also identified a number of typically achieving children who were identified as having borderline speech and language difficulty and should be closely monitored

Rolandic Epilepsy And Dyslexia.

Although benign epilepsy with centrotemporal spikes (BECTS) is an idiopathic, age-related epilepsy syndrome with favorable outcome, recent studies have shown impairment in specific neuropsychological tests. The objective of this study was to analyze the comorbidity between dyslexia and BECTS. Thirty-one patients with clinical and electroencephalographic diagnosis of BECTS (group A) and 31 paired children (group B) underwent a language and neuropsychological assessment performed with several standardized protocols. Our findings were categorized as: a) dyslexia; b) other difficulties; c) without difficulties. Our results were compared and statistically analyzed. Our data showed that dyslexia occurred in 19.4% and other difficulties in 74.2% of our patients. This was highly significant when compared with the control group (p<0.001). Phonological awareness, writing, reading, arithmetic, and memory tests showed a statistically significant difference when comparing both groups. Our findings show significant evidence of the occurrence of dyslexia in patients with BECTS.

Living conditions and receptive vocabulary of children aged two to five years

OBJECTIVE: To assess the receptive vocabulary of children aged between two years and six months and five years and eleven months who were attending childcare centers and kindergarten schools. METHODS: An analytical cross-sectional study was carried out in the municipality of Embu, Southeastern Brazil. The Peabody Picture Vocabulary Test and analysis of factors associated with children's performance were applied. The sample consisted of 201 children of both genders, aged between two and six years. Statistical analysis was performed using multivariate analysis and logistic regression model. The dependent variable analyzed was test performance and the independent variables were child's age, mother's level of education and family socio-demographic characteristics. RESULTS: It was observed that 44.3% of the children had performances in the test that were below what would be expected for their age. The factors associated with the best performances in the test were child's age (OR=2.4; 95% CI: 1.6-3.5) and mother's education level (OR= 3.2; 95% CI: 1.3-7.4). CONCLUSIONS: Mother's education level is important for child's language development. Settings such as childcare and kindergarten schools are protective factors for child development in families of low income and education.

Performance of a Brazilian population on the test of functional health literacy in adults

OBJECTIVE: To analyze the scoring obtained by an instrument, which evaluates the ability to read and understand items in the health care setting, according to education and age. METHODS: The short version of the Test of Functional Health Literacy in Adults was administered to 312 healthy participants of different ages and years of schooling. The study was conducted between 2006 and 2007, in the city of São Paulo, Southeastern Brazil. The test includes actual materials such as pill bottles and appointment slips and measures reading comprehension, assessing the ability to read and correctly pronounce a list of words and understand both prose passages and numerical information. Pearson partial correlations and a multiple regression model were used to verify the association between its scores and education and age. RESULTS: The mean age of the sample was 47.3 years(sd=16.8) and the mean education was 9.7 years(sd=5; range: 1 - 17). A total of 32.4% of the sample showed literacy/numeracy deficits, scoring in the inadequate and marginal functional health literacy ranges. Among the elderly (65 years or older) this rate increased to 51.6%. There was a positive correlation between schooling and scores (r=0.74; p<0.01) and a negative correlation between age and the scores (r=-0.259; p<0.01). The correlation between the scores and age was not significant when the effects of education were held constant (rp=-0.031, p=0.584). A significant association (B=3.877, Beta =0.733; p<0.001) was found between schooling and scores. Age was not a significant predictor in this model (B=-0.035, Beta=-0.22; p=0.584). CONCLUSIONS: The short version of the Test of Functional Health Literacy in Adults was a suitable tool to assess health literacy in the study population. The high number of individuals classified as functional illiterates in this test highlights the importance of special assistance to help them properly understand directions for healthcare.

”Kielestä kiinni”. Kuudesluokkalaisten maahanmuuttajaoppilaiden suomen kielen tason vaihtelut

Tämän tutkimuksen tarkoituksena on selvittää, minkälaista vaihtelua esiintyy maahanmuuttajaoppilaiden suomen kielen taidoissa peruskoulun kuudennella luokalla. Tutkimuksen tavoitteena on myös selvittää, minkälainen yhteys taustamuuttujilla (sukupuoli, äidinkieli, maahantuloikä, maahantulon syy, maassaoloaika ja vanhempien koulutausta) ja opetusjärjestelyillä, kuten perusopetukseen valmistavalla opetuksella, suomi toisena kielenä -opetuksella ja oman äidinkielen opetuksella, on suomen kielen taidon tasoon. Lisäksi tutkimuksen tavoitteena on selvittää oppilaan käyttämän kielen (suomen kieli ja äidinkieli) yhteyttä suomen kielen taidon tasoon. Tutkimusmetodina toimi mixed methods -tutkimus, ja tutkimuksen lähestymistapoja olivat kvantitatiivinen survey-tutkimus ja kvalitatiivinen sisällön analyysi. Tutkimukseen osallistui 219 maahanmuuttajaoppilasta 20:stä Turun koulusta. Tutkimusaineisto kerättiin Turun erityisopettajien ja suomi toisena kielenä -opettajien laatiman kielitestipaketin avulla. Oppilaan suullista ja kirjallista tuottamista arvioivat lasta opettavat opettajat eurooppalaisen viitekehyksen kielitaitotasojen kriteereitä käyttäen. Oppilaat arvioivat omaa äidinkielen ja suomen kielen taitoaan. Lisäksi oppilaat ja vanhemmat täyttivät tutkijan laatimat taustatietolomakkeet. Kielitestien tulosten mukaan oppilaista yli puolella oli tyydyttävä suomen kielen taito. Kaikista neljästä kielellisestä osiosta maahanmuuttajataustaiset oppilaat menestyivät parhaiten rakennekokeessa ja sanelussa, kun taas kuullun ja luetun ymmärtämisen tulokset olivat heikompia. Opettajien arviointien perusteella oppilaiden suulliset taidot vastasivat keskimäärin itsenäisen kielenkäyttäjän osaajan tasoa (B2) ja kirjoittamistaidot kynnystasoa (B1). Oppilaiden suomi toisena kielenä -arvosanan keskiarvo oli 7,26. Suomessa asumisen kestolla, maahantulon syyllä, äidinkielellä, maahantuloiällä, ja vanhempien koulutaustaustalla oli tilastollisesti merkitsevä yhteys suomen kielen taidon tasoon. Mitä kauemmin oppilaat olivat asuneet Suomessa ja mitä nuorempina he olivat tulleet Suomeen, sitä paremmin he menestyivät kielitesteissä. Paluumuuttajat menestyivät kielitaitotehtävissä kaikkein parhaiten ja pakolaiset heikoiten. Somalinkieliset erottuivat muista kieliryhmän edustajista heikoimpina suomen kielen taidon tasoltaan. Venäjänkieliset ja vietnaminkieliset saavuttivat parhaat tulokset kaikissa mittareissa. Erityisesti äidin korkeampi koulutustaso oli yhteydessä oppilaiden korkeampaan suomen kielen taidon tasoon. Oppilaat arvioivat suomen kielen taitonsa omaa äidinkieltään paremmaksi puhumisessa, lukemisessa ja kirjoittamisessa. Parhaiten eri mittareissa menestyivät oppilaat, jotka eivät olleet osallistuneet perusopetukseen valmistavaan opetukseen eivätkä erilliseen suomi toisena kielenä -opetukseen. Omaa äidinkieltään enemmän opiskelleet menestyivät kielitaitotehtävissä paremmin kuin vähän aikaa omaa äidinkieltään opiskelleet, mutta yhtä hyvin kuin ne, jotka eivät olleet opiskelleet omaa äidinkieltään lainkaan. Oppilaat, jotka puhuivat kaveriensa kanssa sekä omaa äidinkieltään että suomen kieltä, osoittautuivat kielitaidon tasoltaan paremmiksi kielitesteissä ja opettajien arvioinneissa.

Vers un outil d'évaluation du langage préscolaire et détecteur de préalables pour l'éducation de base au Cameroun en cas de retard de langage

L’étude présente l’élaboration du premier outil d’évaluation normalisée du langage destiné aux enfants francophones d’âge préscolaire des pays africains qui se caractérisent par l’absence de services publics en orthophonie et la méconnaissance des retards de langage. En s’inspirant des techniques psychométriques langagières utilisées en Amérique du nord et en se basant sur les théories d’acquisition du langage, on a construit un outil appelé Batterie de tests de dépistage approfondi (BATEDA) qui compte onze tests répartis en trois sous-batteries évaluant respectivement l’intégrité des modalités de transmission du langage (BATEM), les composantes langagières (BATEL) et la mémoire verbale (TMV). A partir d’un échantillon de 159 enfants camerounais francophones, on a normalisé la batterie suivant la cote z et les rangs en centile. Les tests présentent une fiabilité inter-juge et intra-juge (p<0,05), une cohérence interne globale d’environ 96% (α de Cronbach=0,958) et une validité prédictive de la réussite scolaire des enfants (r=0,700). Les stratégies d’application de la BATEDA visent à favoriser la pratique du dépistage systématique et la prise en charge des retards de langage au Cameroun, en mettant à contribution les enseignants et les parents comme principaux intervenants. Les implications de cette étude sont de trois ordres : (1) une meilleure connaissance des difficultés langagières, la revalorisation des personnes atteintes et une attitude de vigilance sociale; (2) l’instauration de la pratique de dépistage précoce favorable à l’intervention; (3) une potentielle diminution du taux d’exclusion et d’abandon scolaire d’enfants présentant des retards langagiers à travers un enseignement ciblé en leur faveur.

Desempenho de escolares com distúrbio específico de leitura em programa de remediação.

BACKGROUND: Specific reading disability is caused by disruptions in the language abilities. AIM: To characterize the neurological, cognitive and phonological performances of scholars with specific reading disabilities pre and post a remediation program. METHOD: Group I consisted of ten scholars with specific reading disability who did not undergo the remediation program. Group II consisted of ten scholars with specific reading disabilities who took part in the proposed program. Neurological, psychological and phonological evaluations were made, as well as a test of scholastic performance and of reading and writing before and after the program. RESULTS: The scholars who underwent the remediation program demonstrated improvements in their neurological and cognitive performances and also in the processing of phonological information. CONCLUSION: Favoring of the emergence of phonological and syntactic awareness after the remediation program.

BACKGROUND: X-Fragile Syndrome. AIM: To compile information about the language, cognitive and behavior alterations in the X-Fragile Syndrome, using the results of previously published studies and to present the standardized instruments used as testing materials. CONCLUSION: studies used formal and informal testing to assess language. The results present variability regarding the linguistic deficits, which are influenced by the level of the cognitive deficit and behavior alterations. Alterations of the oral praxes and of speech articulation are also expected.

Phonological remediation program in students with developmental dyslexia

Background: program for phonological remediation in developmental dyslexia. Aim: to verify the efficacy of a program for phonological remediation in students with developmental dyslexia. Specific goals of this study involved the comparison of the linguistic-cognitive performance of students with developmental dyslexia with that of students considered good readers; to compare the results obtained in pre and post-testing situations of students with dyslexia who were and were not submitted to the program; and to compare the results obtained with the phonological remediation program in students with developmental dyslexia to those obtained in good readers. Method: participants of this study were 24 students who were divided as follows: Group I (GI) was divided in two other groups - Gle with 6 students with developmental dyslexia who were submitted to the program; and Glc with 6 students with developmental dyslexia who were not submitted to the program; Group II (GII) was also divided in two other groups - GIIe with 6 good readers who were submitted to the program, and GIIc with 6 good readers who were not submitted to the program. The phonological remediation program (Gonzalez & Rosquete, 2002) was developed in three stages: pre-testing, training and post-testing. Results: results indicate that GI presented a lower performance in phonological skills, reading and writing when compared to GII in the pre-testing situation. However, GIe presented a similar performance to that of GII in the post-testing situation, indicating the effectiveness of the phonological remediation program in students with developmental dyslexia. Conclusion: this study made evident the effectiveness of the phonological remediation program in students with developmental dyslexia.

Envelhecimento, linguagem e memória visuo-espacial: um estudo comparativo exploratório do desempenho humano em testes neuropsicológicos selecionados

O reconhecimento dos limites entre o envelhecimento normal e o patológico é essencial para a adoção de políticas de saúde baseadas em evidências para o grupo etário acima de 65 anos. Este estudo é parte de um esforço sistemático que o grupo de pesquisa do Laboratório de Investigações em Neurodegeneração e Infecção da Universidade Federal do Pará tem feito para fornecer informações translacionais sobre a neurobiologia do envelhecimento normal e alterada. A meta principal em longo prazo é permitir políticas públicas para o envelhecimento saudável na Região Amazônica. No presente trabalho investigamos os efeitos do envelhecimento sobre os desempenhos em testes neuropsicológicos selecionados para avaliar aprendizagem, memória e alterações de linguagem. 29 adultos jovens (29,9 ± 1,06 anos) e 31 idosos (74,1 ± 1,15 anos) saudáveis foram submetidos aos testes e os resultados de seus desempenhos foram comparados por testes paramétricos e estatística multivariada. Uma anamnese e uma variedade de testes cognitivos, incluindo Mini Exame do Estado Mental, tarefas visuo-espaciais de aprendizagem e de memória da bateria de testes neuropsicológicos automatizados - CANTAB e testes de linguagem incluindo fluência verbal semântica e fonológica, teste de nomeação de Boston reduzido, performance narrativa utilizando a figura “o roubo dos biscoitos” e alguns testes da Bateria Montreal de Comunicação - MAC. O programa BioEstat versão 5.0 e o pacote estatístico SPSS foram utilizados para a análise. O teste paramétrico t de Student ou o não paramétrico de Mann-Whitney foram aplicados para detectar diferenças significativas (fixadas em valores de p <0,05). Os grupos foram pareados por escolaridade e incluiu homens e mulheres. A análise das subcategorias que compõem o MEEM mostrou diferença significativa apenas na recuperação da memória de evocação de lista de palavras, em que o grupo de idosos apresentou pior desempenho em comparação com o grupo de jovens. Foram encontradas diferenças estatisticamente significativas entre os desempenhos de idosos e jovens adultos nos seguintes testes de linguagem: 1) Nomeação de Boston, 2) Testes de Narrativa, 3) Metáforas; 4) Prosódia Emocional e Linguística. Em comparação com os adultos jovens, indivíduos idosos apresentaram pior desempenho em 10 medidas diferentes nos testes de memória visuo-espacial e de aprendizagem do CANTAB. Distâncias Euclidianas e análise discriminante obtidas a partir do CANTAB e dos testes de linguagem demonstraram que os primeiros distinguem os grupos com maior resolução. Os efeitos do envelhecimento sobre o desempenho nos testes neuropsicológicos selecionados revelam que a Bateria CANTAB, empregada para testar a memória visuo-espacial, é mais sensível e discrimina melhor a formação de subgrupos tanto no grupo de adultos jovens quanto no grupo de idosos. Por essa razão sugerimos que a aplicação em larga escala de testes selecionados da bateria CANTAB, tanto em estudos transversais como em longitudinais, vai aumentar nossa capacidade de resolução na distinção dos limites entre o envelhecimento normal e o patológico.

Estudo exploratório comparativo do declínio cognitivo senil após estimulação multissensorial e cognitiva em idosos institucionalizados e não institucionalizados

O objetivo do presente trabalho foi investigar, empregando testes neuropsicológicos selecionados, a duração dos efeitos benéficos do programa de estimulação multissensorial e cognitiva realizado em idosos vivendo em instituições de longa permanência ou em comunidade. Os participantes do estudo foram idosos institucionalizados (n=20, 75,1 ± 6,8 anos de idade) e não institucionalizados (n=15, 74,1 ± 3,9 anos de idade), com 65 anos de idade ou mais, sem histórico de traumatismo crânio-encefálico, acidente vascular encefálico ou depressão primária, acuidade visual mínima 20/30 mensurada pelo Teste de Snellen e que participaram regularmente do Programa de Estimulação Multissensorial e Cognitiva. Foram realizadas reavaliações em cinco períodos (2, 4, 6, 8 e 12 meses) após a finalização da intervenção multissensorial e cognitiva. Para isso empregou-se o Mini Exame do Estado Mental (MEEM); nomeação de Boston; fluência verbal semântica (FVS) e fonológica (FVF), testes da Bateria Montreal de Avaliação da Comunicação (MAC), Teste de Narrativa “Roubo de Biscoitos” e testes neuropsicológicos selecionados da Bateria Cambridge (CANTAB) incluindo: Triagem Motora (Motor Screening – MOT); Processamento Rápido de Informação Visual (Rapid Visual Information Processing – RVP); Tempo de Reação (Reaction Time - RTI); Aprendizagem Pareada (Paired Associates Learning - PAL); Memória de Trabalho Espacial (Spatial Working Memory - SWM) e Pareamento com Atraso (Delayed matching to sample - DMS). Os resultados apontaram diferenças estatisticamente significativas entre os grupos revelando taxa de declínio cognitivo maior nos idosos institucionalizados. Esses resultados confirmam sugestão anterior de que o ambiente pobre de estímulos somato-motores e cognitivos das instituições de longa permanência aceleram o declínio cognitivo senil. Além disso, a análise das curvas ROC seguido dos cálculos de sensibilidade, especificidade e eficiência para cada teste revelou que os testes da bateria CANTAB para memória e aprendizado espacial pareado assim como para memória espacial de trabalho permitiram a distinção entre os grupos I e NI em todas janelas de reavaliação. Os resultados demonstraram que uma vez cessado o programa de estimulação, se observa em ambos os grupos declínio cognitivo progressivo, com perdas mais precoces e mais intensas nos idosos institucionalizados do que naqueles vivendo em comunidade com suas famílias. Além disso, observou-se que a duração dos efeitos benéficos sobre o desempenho nos testes neuropsicológicos de ambos os grupos é heterogêneo, e que os efeitos de proteção guardam relação estreita com a natureza das oficinas. Por conta disso os escores dos testes de linguagem declinaram mais lentamente. Os resultados reúnem evidências que permitem a recomendação de programas regulares de estimulação somatomotora e cognitiva para idosos institucionalizados com o intuito de promover a redução da taxa de progressão do declínio cognitivo senil.

Impact of benign childhood epilepsy with centrotemporal spikes (BECTS) on school performance

BECTS represents the vast majority of childhood focal epilepsy. Owing to the age peculiarity of children who suffer from this disease, i.e., school-going age of between 6 and 9 years, the condition is often referred to as a school disorder by parents and teachers. Objective: The aim of this study was to evaluate the academic performance of children with BED'S, according to the clinical and electroencephalographic ILAE criteria, and compare the results of neuropsychological tests of language and attention to the frequency of epileptic discharges. Methods: The performances of 40 school children with BED'S were evaluated by applying a school performance test (SBT), neuropsychological tests (WISC and Trail-Making), and language tests (Illinois Test Psycholinguistic Abilities - ITPA - and Staggered Spondaic Word - SSW). The same tests were applied in the control group. Results: Children with BED'S, when compared to those in the control group, showed lower scores in academic performance (SPT), digits and similarities subtests of WISC, auditory processing subtest of SSW, and ITPA - representational and automatic level. The study showed that epileptic discharges did not influence the results. Conclusion: Children with BED'S scored significantly lower scores in tests on academic performance, when compared with those in the control group probably due to executive dysfunction.
