This single-blind randomized controlled trial (RCT) study was planned to examine the effect of the Cognitive Orientation to Daily Occupational Performance (CO-OP) intervention on occupational performance and executive functions through daily routines children with attention deficit hyperactivity disorder (ADHD). Using a simple random method, the children were divided into two groups: n = 15 in the CO-OP group (4 girls, 11 boys) and n = 15 in the control group (3 girls, 12 boys). CO-OP intervention included 12 sessions (2 sessions per week, each lasting 1 hour, 6 weeks in total) focusing on teaching cognitive strategies to improve daily living activities. These sessions involved personalized goal setting, performance analysis, and the application of cognitive strategies to enhance executive function and occupational performance in children with ADHD. The data were collected by assessing the children with the Canadian Occupational Performance Measure, Goal Attainment Scaling, and Executive Functions and Occupational Routines Scale at the beginning and end of the study. When comparing the pre- and post-evaluations of the CO-OP group, statistically significant improvements were noted in occupational performance and satisfaction (p < 0.001), occupational performance goals (p < 0.001), and executive functions through daily routines (p < 0.05). Test results for differences in posttest scores between the two groups showed that the CO-OP group had significantly better activity performance and satisfaction (p < 0.001), as well as gains in social routines for executive skills (p < 0.05), compared to the control group. The findings suggest that the CO-OP approach represents a promising and effective method for facilitating skill acquisition in various activities among children diagnosed with ADHD. Trial registration: This research was registered to clinical trials with the code NCT05125120.
This study aims to investigate the association between developmental language disorder (DLD) and depressive symptoms in preschool-aged children, building upon previous research that has demonstrated emotional difficulties in children with DLD. Forty-one children with DLD or children at risk for DLD (DLD group) and 41 children with typical language development (TLD) were included in this study. Language development was evaluated using the TEDIL test which is a Turkish adaptation of the Test of Early Language Development-3. Auto acoustic Emissions Testing and Immittance-Metric Assessment were used to exclude children with hearing impairment. Developmental delays were excluded by Denver Developmental Screening Test II. Mothers filled out the Sociodemographic Data Form and the Child Depressive Symptoms Assessment Scale. The results demonstrate that children in DLD group scored significantly higher on the Child Depressive Symptoms Assessment Scale, manifesting increased levels of aggression, separation anxiety, impulsivity, hyperactivity, and encountering greater social adaptation difficulties and deterioration in cognitive processes than TLD. Multivariate regression analysis suggests that increased impulsivity and hyperactivity, alongside social and cognitive challenges, are predictors of DLD. The study concludes that depressive symptoms are more prevalent in children in DLD group than in their typically developing counterparts. These findings underscore the necessity for targeted psychiatric and pedagogical interventions, as well as individualized educational programs that cater to the socio-emotional and cognitive needs of children with DLD.
Objective: To explore the relationship between physical fitness index and executive function in Chinese adolescents, and to provide a reference for improving the development of executive function in Chinese adolescents.
Methods: From September to December 2023, 5336 adolescents aged 13 to 18 years were selected by stratified whole cluster random sampling method in six regions of China for physical fitness and executive function tests. The relationship between adolescent physical fitness index and executive function was analyzed using t-test, ANOVA, Pearson's correlation, and logistic regression.
Results: The correlation coefficients between adolescents' physical fitness index and inhibitory control reaction time were all 0.00094, p > 0.05; the correlation coefficients between adolescents' physical fitness index and working memory (1-back, 2-back) reaction time were -0.13 and -0.093, respectively, p < .05; the correlation coefficients between adolescents' physical fitness index and cognitive flexibility reaction time were -0.17 and -0.18, p < .05. Logistic regression analyses showed that 1-back, 2-back, and cognitive flexibility were significantly and positively correlated with physical fitness index in Models 1, 2, and 3 (all p values less than.01). The coefficients of inhibitory control were not significant in all three models (p > .05), and there was no significant relationship with physical fitness index.
Conclusion: The physical fitness index of Chinese adolescents has a significant positive correlation with working memory and cognitive flexibility, but not with inhibitory control, i.e. the higher the physical fitness index, the better the working memory and cognitive flexibility.
The relationship between brainwave oscillations and Attention-Deficit/Hyperactivity Disorder (ADHD)-related cognitive challenges is a trending proposition in the field of Cognitive Neuroscience. Studies suggest the role of brainwave oscillations in the symptom expressions of ADHD-diagnosed children. Intervention studies have further suggested the scope of brain stimulation techniques in improving cognition. The current manuscript explored the effect of changes in the brainwaves post-sensory entrainment on cognitive performance of children. We calculated each participant's brainwave difference and ratios of theta, alpha, and beta power after the entrainment sessions. Further, we explored possible correlations between these values and the psychometric scores. The beta resting state showed the strongest association with selective attention performance of all participants. Theta-beta ratio (TBR) showed an inverse correlation with selective attention and working memory performances. The theta frequency was associated with decreased working performance in children without ADHD. Our findings also suggest a predominant role of TBR than the theta-alpha ratio in determining the cognitive performance of children with ADHD. The individual differences in the entrainment reception were attributed to the participant's age, IQ, and their innate baseline frequencies. The implications of our findings can initiate substantiating brainwave-based entrainment sessions as a therapeutic modality to improve cognition among children.
Executive function (EF) in specific learning disorders (SLD) has been investigated using mainly cool EF tasks, whilst less is known about hot EF and theory of mind (ToM) in this population. The aim of this study was to examine group differences in hot and cool EF and ToM in school-aged children with SLD relative to typically developing peers. It also attempted to investigate whether EF measures are significant predictors of ToM in SLD and typical development. Cross-sectional data were collected from 135 school-aged children with and without SLD (8-10 years old), tested on measures of cool & hot EF and ToM. Significant group differences were observed in EFs inhibition (p= .04), working memory (p= .04) and delay of gratification (p < .001), as well as ToM mental state/emotion recognition (p = .019). Inhibition and planning contributed to 22% of the explained variance of ToM mental state/emotion recognition, but not false belief overall. Results suggest that cool EF may be a crucial predictor of ToM in children with and without SLD. Finally, stepwise logistic regression analysis identified specific hot EF and ToM measures contributing to group differentiation, specifically delay of gratification (odds ratio=.995, 95% CI [.993-.998]) and mental state/emotion recognition (odds ratio= .89, 95% CI [.796-.995]). This study contributes to our understanding of cognitive deficits and socio-cognitive impairment in children with SLD, which hold promise for informing interventions aimed at addressing these cognitive challenges.
The purpose of this study is to analyze the Linguistic and Metalinguistic abilities of Persian-speaking individuals with Intellectual disorder to identify the areas and results of the research carried out in order to recognize their main linguistic features, the research gaps, and also guide future research. To this end, first, related keywords were searched and related topics were separated. Then, by reading the abstracts and, if necessary, the entire articles, the unrelated articles were removed. The articles were categorized and studied on linguistic and metalinguistic characters in four areas such as semantics, phonetics and phonology, morphology and syntax, and pragmatics. In addition, to investigate the effect of bilingualism and gender on the linguistic abilities of these individuals, the findings related to studies in the field of bilingualism and gender were examined in a separate section. From the general review of about 39 studies found, we found that in the fewest studies, the field of pragmatics was dealt with. The general results of the investigation were presented in the table of the results section in addition, in phonological studies, there was no significant difference in phonological awareness between girls and boys. In bilinguals, phonological awareness skills were related to their spelling skills.
This study aimed to investigate impairments in social cognition in youth with specific learning disorder (SLD) through a cross sectional study. Eighty six adolescents which include of 43 SLD and 43 typically developing (TD) children completed a battery of tests to analyze social cognition, emotional process and clinical psychopathological profile. SLD group performed significantly worse than healthy controls in facial ER total accuracy score (Cohen d = .77) and Stroop interference (Cohen d = .92). In individual emotion analyses, patients with SLD have a very high deficiency in recognition of angry faces (Cohen d = .89). Between-group difference was also significant for Stroop congruent and facilitation scores (Cohen d = .99). The Specific Learning Disorder Symptom Check List-Parent Form scores were significant -and only- predictor of the model which for total accuracy score of facial recognition. The results of this study supported an impairment in emotion recognition and executive functions in adolescents with SLD but causality seems still unclear.
Attention-deficit hyperactivity disorder (ADHD) is a common chronic neurodevelopmental disorder characterized by symptoms of inattention, overactivity, and/or impulsiveness. The prevalence of ADHD varies in different settings and there have been voices raised to call for more objective measures in order to avoid over- and underdiagnosing of ADHD. Auditory Brainstem Response (ABR) is a method where click shaped sounds evoke potentials that are recorder from electrodes on the skull of a patient. The aim of this study was to explore possible alterations in the ABR of 29 patients with ADHD compared to 39 healthy controls. We used a forward masked sound. We found differences in ABR that correspond to the thalamic area. The thalamus seems to play an active role in regulation of activity level in ADHD. More research is needed to draw any further conclusions on using ABR as an objective measurement to detect ADHD.
Background: Cerebral palsy (CP) is a posture and movement disorder, however; it often includes disturbance of different aspects of cognitive function. This study aimed to investigate if combined functional strength training (FST) and cognitive intervention are more effective than either of them alone on gross motor function in children with spastic diplegic CP.
Methods: Sixty-four children with spastic diplegic CP, with ages ranging from 8 to 12 years, were assigned randomly into four treatment groups; Group I; FST, group II; cognitive training, group III; combined FST and cognitive training, group IV; conventional physical therapy. The Gross Motor Function Measure (GMFM-88) was used to assess gross motor function at baseline, post-treatment, and 6 months follow-up.
Results: Group III achieved a significant improvement in GMFM-88 when compared to other groups post-treatment and at follow-up.
Conclusion: This study suggests that combined lower limb FST and cognitive intervention had the potential to produce significantly more favorable effects than the single use of either of them on gross motor function in children with spastic diplegia.
