    The comparison of psychological factors and executive functions of children with Attention Deficit Hyperactivity Disorder and Cognitive Disengagement Syndrome to ADHD and ADHD comorbid with Oppositional Defiant Disorder
    (SAGE Publications Inc., 2024-10) İnci İzmir, Sevim Berrin; Aktan, Zekeriya Deniz; Ercan, Eyüp Sabri
    Objective: The study aims to examine family functionality, emotion regulation difficulties, preference for loneliness, social exclusion, internalizing and externalizing disorders, and executive functions in children with Attention Deficit Hyperactivity Disorder (ADHD) and Cognitive Disengagement Syndrome (CDS) and compare with ADHD, and ADHD+ Oppositional Defiant Disorder (ODD). Method: This study included 842 children aged 8–12 years. The subjects were categorized according to DSM-V as ADHD (n = 246), ADHD + ODD (n = 212), ADHD + CDS (n = 176), and Control group (n = 207). The solitude and social exclusion, difficulties in emotion dysregulation and Barkley SCT scales, Child Behavior Checklist, family assessment device, and Central Vital Signs (CNSVS) test were used. Results: According to the study, children with ADHD + CDS had higher rates of internalizing disorders. They also preferred being alone and experienced more difficulty communicating with their parents and solving problems within the family. Additionally, these children had difficulty recognizing and understanding the emotional reactions of others. The ADHD + ODD group presented a poorer performance on CNSVS domain tests except for the psychomotor speed test than other groups. Also, ADHD + CDS children had the lowest psychomotor speed scores and lower scores on reaction time and cognitive flexibility than pure ADHD children. Conclusion: This study will contribute to the etiology, treatment, and clinical discrimination of ADHD + CDS.

    Reliability of direct-to-home teleneuropsychological assessment: a within-subject design study
    (Routledge, 2025-07-04) Yıldırım, Elif; Soncu Büyükişcan, Ezgi; Akça Kalem, Şükriye; Gürvit, Hakan
    Objective: During the COVID-19 pandemic, the need to continue diagnosis and treatment processes, in addition to scientific research, led to a rapid shift towards direct-to-home tele-neuropsychology administrations, the reliability and validity of which had not been clearly established then. This study, therefore, aimed to examine the reliability of direct-to-home tele-neuropsychological assessment (TNP). Method: The sample included 105 cognitively healthy individuals aged between 50–83 years, and 47 patients diagnosed with neurocognitive disorders (mild cognitive impairment and early-stage Alzheimer’s type dementia). All participants underwent both face-to-face and teleneuropsychological assessments in a counterbalanced order. Results: The results revealed that performances across measures of attention, working memory, verbal fluency, verbal and visual memory, and visual perception were comparable across assessment modalities. Intraclass correlation coefficients of the tests ranged from.54 to.92. Conclusions: The findings of the study provide support for direct-to-home teleneuropsychological assessment among patients with neurocognitive disorders. Neuropsychological tests relying on verbal administration and independent of motor performance may represent a reliable alternative for this patient group when administered in settings where external distractions or technological limitations are controlled. For cognitively healthy individuals, on the other hand, the reliability of the TNP application is more questionable for memory and some executive function tests and therefore needs further exploration.

    Theta and Beta1 frequency band values predict dyslexia classification
    (John Wiley and Sons Ltd, 2025-12-29) Eroğlu, Günet; Harb, Mhd Raja Abou
    Dyslexia, impacting children's reading skills, prompts families to seek cost-effective neurofeedback therapy solutions. Utilising machine learning, we identified predictive factors for dyslexia classification. Employing advanced techniques, we gathered 14-channel Quantitative Electroencephalography (QEEG) data from 200 participants, achieving 99.6% dyslexic classification accuracy through cross-validation. During validation, 48% of dyslexic children's sessions were consistently classified as normal, with a 95% confidence interval of 47.31 to 48.68. Focusing on individuals consistently diagnosed with dyslexia during therapy, we found that dyslexic individuals exhibited higher theta values and lower beta1 values compared to typically developing children. This study pioneers machine learning in predicting dyslexia classification factors, offering valuable insights for families considering neurofeedback therapy investment.

    Validation and normative data study for the Turkish version of the movie for the assessment of social cognition (MASC-TR)
    (Oxford University Press, 2026-02-05) Şandor, Serra; Hıdıroğlu-Ongun, Ceren; Tanfer, Mehmet Can; Gürkaş, Sena; Bora, Emre; Yıldırım, Elif
    Objective This study aimed to adapt the Movie for the Assessment of Social Cognition (MASC) into Turkish (MASC-TR), examine its psychometric properties, and establish normative data. Additionally, the study investigated the discriminative validity of the MASC-TR in differentiating individuals with autism spectrum disorder (ASD) from healthy controls. Methods The sample comprised 228 healthy adults and 29 individuals with ASD aged 18–45 years. Participants completed the MASC-TR along with established measures of theory of mind (ToM)—the Reading the Mind in the Eyes Test (RMET) and the Faux Pas Recognition Test (FPRT)—as well as non-social cognitive tasks assessing attention, working memory, and executive functions. Reliability analyses included internal consistency and test–retest reliability. Construct validity was assessed via convergent and discriminant correlations. Group comparisons and receiver operating characteristic analyses were used to evaluate discriminative validity, while multifactorial analysis of variance and regression analyses examined demographic effects. Results The MASC-TR demonstrated acceptable internal consistency (α=0.75) and excellent test–retest reliability (ICC=0.98). Significant positive correlations with RMET and FPRT supported convergent validity. Education level emerged as the only significant demographic predictor of MASC-TR performance. The MASC-TR successfully differentiated individuals with ASD from controls (t=−3.87, p<.001), with an optimal cutoff of 23.5 yielding 97% sensitivity and 52% specificity (area under the curve=0.72). Conclusions The findings indicate that the MASC-TR is a valid and reliable measure of social cognition in Turkish adults. The availability of culturally adapted normative data enhances its clinical and research utility for assessing ToM functioning across populations.
