Evaluating the association between developmental language disorder and depressive symptoms in preschool children.

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.

Sleep, executive functions, and functional impairment in children with specific learning disorder: An investigation of the mediating pathways.

OBJECTIVE: Sleep problems and executive dysfunction are associated with functional impairment in children with neurodevelopmental disorders. In this study, we aimed to investigate these aspects in children with Specific Learning Disorders (SLD) and SLD with comorbid Attention-Deficit Hyperactivity Disorder (ADHD), while also evaluating differences with typically developing (TD) children. Our study hypothesizes that children with SLD, especially those with comorbid ADHD, face greater sleep disturbances and executive function challenges compared to TD peers. We also propose that sleep disturbances aggravate functional impairment and that executive functions mediate this relationship. METHOD: The data obtained from psychiatric evaluations, semi-structured interviews and questionnaires filled out by parents were analyzed. RESULTS: SLD + ADHD group had worse scores in all scales, followed by SLD and TD groups. Mediator analysis demonstrated that executive functions had a mediator role in the relationship between sleep problems and functional impairment. CONCLUSION: Our findings suggest that children with SLD experience more significant difficulties in daily living than their typically developing peers and having ADHD comorbidity, poor executive functions, and additional sleep problems can further exacerbate impairment. Notably, our mediation analysis suggests that executive functions mediate the relationship between sleep disturbances and the severity of functional impairments.

Turkish Validation of the Rapid Interactive Screening Test for Autism in Toddlers.

LAY ABSTRACT: It is important to diagnose autism spectrum disorder at an early age and to start an early intervention program without delay. In this study, we aimed to validate the Rapid Interactive Screening Test for Autism in Toddlers (RITA-T) in a group of Turkish children and found that the RITA-T which has been shown to be a valid and reliable screening test for 18- to 36-month-old children in studies conducted in different countries, is also valid in Turkish children. Similar to previous studies, our results showed that the RITA-T has good sensitivity and specificity in distinguishing children with autism spectrum disorder. We think that our study will contribute to the timely initiation of early intervention programs for many children with autism by enabling a valid test to be used in screening programs.

Evaluation of p300 and spectral resolution in children with attention deficit hyperactivity disorder and specific learning disorder.

This study aims to examine auditory processing, P300 values and functional impairment levels among children with Attention Deficit and Hyperactivity Disorder (ADHD), Specific Learning Disorder (SLD), ADHD+SLD and healthy controls. Children with ADHD (n = 17), SLD (n = 15), ADHD+SLD (n = 15), and healthy controls (n = 15) between the ages of 7-12 were evaluated with K-SADS, Weiss Functional Impairment Rating Scale, Turgay DSM-IV Disruptive Behavior Disorders Rating Scale, The Mathematics, Reading, Writing Assessment Scale and Children's Auditory Performance Scale (CHAPS). Auditory P300 event-related potentials and Spectral-Temporally Modulated Ripple Test (SMRT) were applied. Three patient groups were found to be riskier than healthy controls according to the CHAPS. There was no significant difference between the groups in the SMRT. In post-hoc analyses of P300 parietal amplitudes, ADHD, SLD, and ADHD+SLD were found to be significantly lower than the control group. The amplitudes of the ADHD+SLD were by far the lowest. It has been shown that auditory performance skills and p300 amplitudes are lower in children diagnosed with only ADHD or SLD compared to the control group, with the lowest values observed in ADHD+SLD. This study suggests that the difficulties with attention and cognitive functions in the ADHD+SLD are more severe than ADHD and/or SLD without comorbidity.
