History of learning disorders is associated with worse cognitive and functional outcomes in schizophrenia: results from the multicentric FACE-SZ cross-sectional dataset
AbstractSchizophrenia is associated with early neurodevelopmental disorders, including most frequently learning disorders (LD), among them dyslexia and dyspraxia. Despite the demonstrated links between schizophrenia and LD, specific clinical patterns of the schizophrenia with a history of LD subgroup remain unknown. The aim of the present study was to investigate cognitive impairment, symptoms and functional outcome associated with a history of LD in a large cross-sectional, multicentric, sample of schizophrenia subjects. 492 community-dwelling subjects with schizophrenia (75.6% male, mean age 30.8  years) were consecutiv...

Multimodal intervention in 8- to 13-year-old French dyslexic readers: Study protocol for a randomized multicenter controlled crossover trial
Developmental dyslexia, a specific and long-lasting learning disorder that prevents children from becoming efficient and fluent readers, has a severe impact on academic learning and behavior and may compromise...

How visual attention span and phonological skills contribute to N170 print tuning: An EEG study in French dyslexic students
Brain Lang. 2022 Sep 2;234:105176. doi: 10.1016/j.bandl.2022.105176. Online ahead of print.ABSTRACTDevelopmental dyslexia is a disorder characterized by a sustainable learning deficit in reading. Based on ERP-driven approaches focusing on the visual word form area, electrophysiological studies have pointed a lack of visual expertise for written word recognition in dyslexic readers by contrasting the left-lateralized N170 amplitudes elicited by alphabetic versus non-alphabetic stimuli. Here, we investigated in 22 dyslexic participants and 22 age-matched control subjects how two behavioural abilities potentially affected in ...

What’s morphology got to do with it: Oral reading fluency in adolescents with dyslexia.
In this study, French adolescents with and without dyslexia were assessed on their morphological awareness and processing skills, along with reading fluency. Morphological awareness was assessed with a suffixation decision task, while a primed lexical decision task was used to assess morphological processing. Primes shared four possible relationships with the targets: morphological, semantic, orthographic, or unrelated. Group differences were not found for morphological awareness. In contrast, the group of adolescents with dyslexia showed a greater benefit of morphological priming. A continuous approach where reading fluen...

A 3-year longitudinal investigation of the overlap and stability of English and French word reading difficulties in French immersion children
Ann Dyslexia. 2022 Jul 25. doi: 10.1007/s11881-022-00265-1. Online ahead of print.ABSTRACTExtensive research has demonstrated the importance of struggling reader identification in monolingual children Compton et al. (Journal of Educational Psychology, 102, 327-340, 2010). However, very few studies have explored identification of struggling readers in bilinguals. The aim of this study was to investigate (1) the overlap of word reading difficulties in English and French, (2) the difference in overlap when word reading fluency skills are included in struggling reader classification, and (3) the stability of English and French...

Rhythm as an independent determinant of developmental dyslexia.
In this study, we investigated the independent contribution of predictive timing to DD above and beyond the motor and cognitive dysfunctions typically associated with this disorder. Twenty-one children with DD (aged 8–12, nine females) and 27 controls (14 females) were evaluated on perceptual timing, finger tapping, fine motor control, as well as attention and executive tasks. Participants were native French speakers from various socioeconomic backgrounds. The performance of children with DD was poorer than that of controls in most of the tasks. Predictors of DD, as identified by logistic regression modeling, were beat p...

A universal reading network and its modulation by writing system and reading ability in French and Chinese children
Are the brain mechanisms of reading acquisition similar across writing systems? And do similar brain anomalies underlie reading difficulties in alphabetic and ideographic reading systems? In a cross-cultural paradigm, we measured the fMRI responses to words, faces and houses in 96 Chinese and French 10-year-old children, half of whom were struggling with reading. We observed a reading circuit which was strikingly similar across languages and consisting of the left fusiform gyrus, superior temporal gyrus/sulcus, precentral and middle frontal gyri. Activations in some of these areas were modulated either by language or by re...

Do children with dyslexia present a handwriting deficit? Impact of word orthographic and graphic complexity on handwriting and spelling performance
Publication date: February 2020Source: Research in Developmental Disabilities, Volume 97Author(s): Claire Gosse, Marie Van ReybroeckAbstractSeveral studies have demonstrated that children with dyslexia frequently show poor and slow handwriting skills. It is not clear whether these difficulties are a consequence of their spelling deficit or if they arise from graphomotor difficulties. The present study aims to test the hypothesis of the presence of handwriting difficulties in dyslexia, through the investigation of the impact of graphic and orthographic complexity of words on writing. Participants were all monolingual French...

English phonological specificity predicts early French reading difficulty in emerging bilingual children.
Abstract The purpose of the present study was to examine the predictive value of a dynamic test of English and French lexical specificity on at-risk reading classification in 13 at-risk and 44 not at-risk emerging English (L1)-French (L2) bilingual Grade 1 children (M = 75.87 months, SD = 3.18) enrolled in an early French immersion program in Canada. Lexical specificity was assessed with a computerized word learning game in which children were taught new English (e.g., "foal" and "sole") and French (e.g., bac "bin" and bague "ring") word pairs contrasted by minimal phonological differences. The results indicated t...

Neuropsychological Functioning and Temperament Traits in a Czech Sample of Children and Adolescents at Familial Risk of Bipolar Disorder
Conclusions: Neuropsychological impairment does not seem to be a trait marker of BD in the premorbid stage. Temperament with low effortful control and low attention focusing might be associated with the development of mood disorders in BO. Introduction Children of parents with bipolar disorder (BD), i.e., bipolar offspring (BO), have an increased risk of developing the disorder than offspring of mentally healthy parents (control offspring; CO), with an estimated heritability of 59% (1). The clinical staging model for BD was developed to improve early interventions and to prevent its onset (2, 3). BO with no symptoms ...

Developmental dyslexia and specific language impairment: distinct syntactic profiles?
Abstract Recent work exploring syntax in developmental dyslexia (DD) has identified morphosyntactic deficits, striking parallelisms between children with DD and specific language impairment (SLI). The question remains open if the underlying causes for such deficits are related to difficulties in phonology, which is affected in DD, or to working memory, as has been previously reported for SLI. We focus on the production of third person accusative clitic pronouns (ACC3) and of homophonous definite determiners in French-speaking children with DD and SLI as well as typically developing (TD) controls. If syntactic comp...
