Angiocentric Glioma Manifesting as Psychotic Symptoms in an Adolescent: a Case Report
(2013) Kadak, M.T.; Demirel, A.; Demir, T.
Cerebral cortical malformations can be associated with psychotic symptoms, and frontal, temporal, and limbic lesions may lead to psychosis-like symptoms. Therefore, these regions have a role in the pathogenesis of psychosis and related symptoms. Here, we report a 13-year-old adolescent who presented with auditory and visual hallucinations, persecutory delusions, and aggression. The patient's symptoms remitted after the resection of the left temporal lobe, fusiform gyrus, uncus, amygdala, and hippocampus. Histological examination revealed angiocentric glioama. We discuss the relationship between psychotic symptoms and the neural network that links the frontal lobe with limbic structures and how it can be disturbed by developmental abnormalities. © 2013 Elsevier GmbH.
Associations Between Online Addiction Attachment Style, Emotion Regulation Depression and Anxiety in General Population Testing the Proposed Diagnostic Criteria for Internet Addiction
(Kure Iletisim Grubu A.S., 2019) Ceyhan, E.; Boysan, M.; Kadak, M.T.
The focus of this study was twofold. The first aim of the study was to investigate psychometric properties of the Turkish version of the Chen Internet Addiction Scale (CIAS). Second, we explored the relations between Internet Addiction, Attachment Style Emotion Regulation, Depression and Anxiety among college students. A total of 754 college students participated in the study. The CIAS, Young Internet Addiction Test (YIAT), Experiences in Close Relationship-Revised (ECR-R), Difficulties in Emotional Regulation Scale (DERS), Center for Epidemiological Studies Depression Scale (CES-D), Beck Anxiety Inventory (BAI), and WHO Disability Assessment Schedule 2.0 (WHODAS 2.0) were administered in the study. The CIAS was subjected to confirmatory factor analysis. The associations between Internet addiction, attachment styles, difficulty in emotion regulation, anxiety and depression were evaluated using one-way analysis of variance and logistic regression analysis. The signal detection analysis showed that a cut value of 64 for the CIAS, with diagnostic accuracy of 97.1% and a cut value of 40 for the YIAT, with diagnostic accuracy of 86.9% were evaluated to be best diagnostic cutoff points. Considering univariate relationships between variables of interest, fearful and preoccupied attachment were significantly associated with pathological Internet use. Logistic regression analyses demonstrated that being male, difficulties in emotional regulation, anxiety and depression statistically significantly contributed to the risk for development of Internet addiction. Internet addiction as indexed by the CIAS cutoff is a highly debilitating mental disorder. © 2019 Kure Iletisim Grubu A.S. All rights reserved.
A Psychometric Investigation of the Turkish Version of the Children's Response Style Scale (Crss) Using Structural Mediational Analysis Approach
(Kure Iletisim Grubu A.S., 2017) Sonkur, A.; Boysan, M.; Kadak, M.T.
The study investigated the psychometric properties of the Turkish version of the Children's Response Style Scale (CRSS). Participants were 1358 students, aged 13-19, and about half of the sample consisted of girls (N= 640, 47.13%). Confrmatory factor analysis was conducted and the original two-factor structure of the CRSS was replicated among the Turkish sample. It was demonstrated that sub-scales of the Turkish version have good internal reliability, testretest reliability and convergent validity. Rumination, meta-cognitions, pathological worry, and thought suppression were found to be signifcant antecedents of depressive symptomatology in adolescents. Consistent with the conceptualization of the response styles theory, distraction was preventive from depressive symptoms. A structural equation model specifed based on an integration of the response styles theory (Nolen-Hoeksema, 1991) and the SelfRegulatory Executive Function (S-REF) model of emotional disorders (Wells, 2000; Wells &Matthews, 1996) detected that signifcant linkages between depression and metacognitions were mediated by thought suppression, rumination and worry among adolescents. Gender differences on measures of cognitive vulnerability factors were substantial that girls revealed a greater tendency to meta-cognitive vulnerability, thought suppression, rumination and pathological worry, while boys scored higher on distraction. Gender differences in depressive symptomatology fell short of signifcance when controlling for cognitive vulnerability factors. Age was not a signifcant antecedent of cognitive vulnerability factors and depressive symptoms. The results are discussed in light of theoretical and empirical evidence in the literature.
