Yayın Assessing the mediating relationships between psychological factors in children with attention deficit hyperactivity disorder and cognitive disengagement syndrome(Routledge Journals, Taylor & Francis Ltd, 2024-04) İnci İzmir, Sevim Berrin; Aktan, Zekeriya Deniz; Ercan, Eyüp SabriThis study aims to investigate the predictive and mediating relationships between emotion dysregulation, internalizing disorders, family functionality, loneliness preference, and executive functions (EF) in children with attention deficit hyperactivity disorder and cognitive disengagement syndrome (ADHD + CDS). This study included 176 children and adolescents (92 boys, 84 girls) who were diagnosed with ADHD + CDS according to the Diagnostic and Statistical Manual of Mental Disorders, the Fifth Edition criteria by a fellowship-trained child and adolescent psychiatrist, between ages 8 -12 (M = 10, SD = 1.52) with a convenience sampling method. The solitude scale for children, difficulties in emotion dysregulation scale, Child Behavior Checklist, Barkley Sluggish Cognitive Tempo Scale, Family assessment device, and CNS Vital Signs test were used. The results showed that difficulty in emotion regulation, preference for loneliness, internalizing disorders and CDS symptom severity did not have a mediating effect between family functionality and EF. Still, emotion dysregulation mediates the relationship between EF and internalizing disorders by itself and through loneliness preference. Also, preference for loneliness and emotion dysregulation had a mediating effect between family functionality and internalizing disorders. Finally, it was found that the effect of emotion regulation difficulty, loneliness preference, and internalizing disorders had a mediating role between CDS symptom severity and family functionality. In conclusion, the information obtained from this study on the etiology of CDS may guide future studies.Yayın Increased cerebral blood flow in the right anterior cingulate cortex and fronto-orbital cortex during go/no-go task in children with ADHD(Taylor & Francis Ltd, 2021-04-01) Baytunca, Muharrem Burak; de Frederick, Blaise; Bolat, Gül Ünsel; Kardaş, Burcu; İnci İzmir, Sevim Berrin; İpçi, Melis; Calli, Cem; Özyurt, Onur; Öngür, Dost; Süren, Serkan; Ercan, Eyüp SabriObjective: Arterial spin labeling (ASL) is a relatively new imaging modality in the field of the cognitive neuroscience. In the present study, we aimed to compare the dynamic regional cerebral blood flow alterations of children with ADHD and healthy controls during a neurocognitive task by using event-related ASL scanning. Methods: The study comprised of 17 healthy controls and 20 children with ADHD. The study subjects were scanned on 3 Tesla MRI scanner to obtain ASL imaging data. Subjects performed go/no-go task during the ASL image acquisition. The image analyses were performed by FEAT (fMRI Expert Analysis Tool) Version 6. Results: The mean age was 10.88 +/- 1.45 and 11 +/- 1.91 for the control and ADHD group, respectively (p = .112). The go/no-go task was utilized during the ASL scanning. The right anterior cingulate cortex (BA32) extending into the frontopolar and orbitofrontal cortices (BA10 and 11) displayed greater activation in ADHD children relative to the control counterparts (p < .001). With a lenient significance threshold, greater activation was revealed in the right-sided frontoparietal regions during the go session, and in the left precuneus during the no-go session. Conclusion: These results indicate that children with ADHD needed to over-activate frontopolar cortex, anterior cingulate as well as the dorsal and ventral attention networks to compensate for the attention demanded in a given cognitive task.Yayın Methylphenidate significantly improves neurocognitive impairments in children with ADHD(Elsevier Ireland Ltd, 2022-03-06) İnci, Sevim Berrin; İpçi, Melis; Ercan, Eyüp SabriThis study aimed to investigate the effects of methylphenidate (MPH) on scores on a neurocognitive test battery for individuals with various presentations of attention deficit/hyperactivity disorder (ADHD) and the effect of comorbidities on executive function. This study included 861 children and adolescents aged 7–17 years who were diagnosed with ADHD according to DSM-V criteria. The CNS Vital Signs Battery was utilized to compare the neuropsychological characteristics and MPH treatment responses of patients with predominantly inattentive (ADHD-I) and combined (ADHD-C) presentations of ADHD. Before MPH administration, a statistically significant difference was observed between groups only for complex attention. In addition, the overall prevalence rate of psychiatric comorbidities was 45.5%, and no statistically significant differences were found in the ADHD-I group pre- versus post-MPH administration. Prior to the administration of MPH, statistically significant differences were observed within the ADHD-C group between those with or without comorbidities. However, after MPH administration, these differences between the groups disappeared. The effects of MPH on improving scores on neuropsychological subtests were similar between the groups with different presentations of ADHD. Additionally, MPH treatment was effective despite the presence of comorbidities.Yayın The relationships of neuropsychological factors and loneliness preference in children with attention deficit hyperactivity disorder and cognitive disengagement syndrome(Routledge Journals, Taylor & Francis Ltd, 2025-04-03) İzmir, Sevim Berrin İnci; Aktan, Zekeriya Deniz; Ercan, Eyüp SabriThis study aimed to examine emotion dysregulation and internalizing disorders mediating the relationship between selective and sustained attention and loneliness preference in children diagnosed with attention deficit hyperactivity disorder (ADHD) and Cognitive Disengagement Syndrome (CDS). This study included 176 children and adolescents between ages 8 and 12. The solitude scale for children, Difficulties in Emotion Regulation Scale, Child Behavior Checklist, Barkley Sluggish Cognitive Tempo Scale, and CNS Vital Signs test were used. The results suggest that difficulties in emotion regulation and having an internalizing disorder had a mediating effect between difficulties in selective attention and preference for the loneliness of children with ADHD + CDS. Also, it was likely that the association between sustained attention and preference for loneliness is mediated by internalizing disorders. The results suggest that the social problems commonly exhibited by children with ADHD + CDS may be related to deficits in sustained and selective attention.Yayın 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 SabriObjective: 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.Yayın Dikkat eksikliği ve hiperaktivite bozukluğu tanısı olan 11-17 yaş arası ergenlerin DEHB belirti şiddeti ile ebeveyn ve arkadaş bağlanmaları arasındaki ilişkiye sosyal bilişin aracılık etkisinin araştırılması(Işık Üniversitesi, Lisansüstü Eğitim Enstitüsü, 2025-06-30) Şişman, Zeynep; Yılmaz Kafalı, Helin; Işık Üniversitesi, Lisansüstü Eğitim Enstitüsü, Klinik Psikoloji Yüksek Lisans Programı; Işık University, School of Graduate Studies, Master’s Program in Clinical PsychologyBu araştırma, Dikkat Eksikliği Hiperaktivite Bozukluğu tanısı alan 11-17 yaş arasındaki ergenlerin ebeveynleri ve arkadaşlarına bağlanmaları ile sosyal bilişleri arasındaki ilişkinin incelenmesini amaçlamıştır. Araştırmanın örneklemi 11-17 yaş aralığında ortalama yaşı 13.08±.501 olan 114’ü erkek 86’sı kız olan toplam 200 ergen katılımcıdan oluşmaktadır. Dehb grubunda 100 katılımcının 56’sı erkek 44’ü kız iken kontrol grubunda 100 katılımcının 58’i erkek 42’si kız katılımcıdır. DEHB grubunun yaş ortalaması 14.06±.496 iken kontrol grubunun 13.08±.348 olarak bulunmuştur. Bakırköy Dr. Sadi Konuk Hastenesi’nde Çocuk ve Ergen Psikiyatrisi Bölümü’nden veriler toplanmıştır. 100 kişiden kalan son 30 kişi zoom online aracılığıyla hediye çeki verilerek tamamlanmıştır. Kontrol grubu Lüleburgaz İlçesi’ndeki ile 11-17 yaş aralığındaki Ergenlerden yüz yüze toplanmıştır. Ebeveyn ve Arkadaşlara Bağlanma Envanteri Gözden geçirilmiş form (EABE-G), Çocuklar için Gözlerden Zihin Okuma Testi, Gaf (Faux Pas) Tanıma Testi Çocuk Formunu araştırmacı öncülülüğünde katılımcılar tarafından yanıtlanmıştır. Katılımcıların ebeveynlerine Bilgilendirilmiş Onam Formu ve Sosyodemografik Bilgi Formu, Çocuk ve Ergenlerde Yıkıcı Davranım Bozuklukları İçin DSMIV’e Dayalı Tarama ve Değerlendirme Ölçeği-Turgay verilmiştir. Aynı zamanda, kontrol grubundaki ergenlerde psikopatoloji olmadığını teyit etmek amacıyla, araştırmacı tarafından Okul Çağı Çocukları İçin Duygulanım Bozuklukları ve Şizofreni Görüşme Çizelgesi Şimdi ve Yaşam boyu Şekli Türkçe Uyarlaması-ÇDŞG-ŞY uygulanmıştır. Araştırmanın hipotezlerini test etmek için Independent student t test, Hiyerarşik Regresyon, One-way Anova, Pearson Korelasyon analizi, Process Makro analizi kullanılmıştır. Yapılan analizler sonucunda, DEHB grubunun aynı zamanda sosyal bilişlerinde tanı almayanlara göre daha kötü performans sergiledikleri bulunmuştur. DEHB şiddeti ile akran ve ebeveyn güvenli bağlanma skorları arasındaki ilişkinin incelendiği korelasyon analizi bulgularına göre, DEHB şiddeti ile akran (r=-0.307) ve ebeveyn (r=-0.528) ile güvenli bağlanmaları arasında orta düzeyde negatif yönde anlamlı bir ilişki bulunmuştur (p<0.01). Ayrıca, DEHB şiddetinin akran bağlanma üzerinde istatistiksel olarak anlamlı ve negatif bir etkiye sahip olduğunu göstermektedir (β = -0.1159, p < .001). GZOT’un DEHB şiddeti ile akran bağlanması arasında indirekt aracılık etkisi bulunmamasına rağmen (β =-0.0167, p = 0.46), Gaf tanımanın istatistiksel olarak anlamlı olacak şekilde bu ilişkiye aracılık ettiği bulunmuştur (β = -0.0992, p = 0.015). Araştırmada; 11-17 yaş arası DEHB tanısı almış ergenlerin ebeveyn ve akranlarına bağlanmaları ve sosyal bilişlerinin tanı almayanlara göre daha düşük düzeyde olduğu bulunmuş ve DEHB şiddetinin ebeveyn ve akrana güvenli bağlanması arasındaki ilişkisine Gaf testinin pozitif yönde aracılık ettiği bulunmuştur. Bulgularımız DEHB tanısı alan ergenler için ebeveyn ve akran desteğinin önemini vurgularken, aynı zamanda sosyal biliş ve bağlanma temelli müdahale programlarının oluşturulmasının ergenlerin yaşamında olumlu yönde etki oluşturabileceği söylenebilir.
