The impact of the prolonged COVID-19 pandemic on adolescents with eating disorders: a follow-up study from Türkiye.

BACKGROUND: At the onset of the pandemic, we conducted a study on adolescents with eating disorders (EDs) and found no deterioration in ED symptoms. The objective of this subsequent study was to conduct a follow-up evaluation of the same cohort and investigate the consequences of the prolonged pandemic. METHODS: This longitudinal study was conducted one year after the first study between May 2021 and June 2021 with 37 adolescents aged 12-18 years (pre-existing EDs). The reassessment included an evaluation of sociodemographic and clinical characteristics, the impact of pandemic-related restrictions on ED behaviors, well-being, and quality of life. All the participants underwent a re-administration of the ED examination questionnaire (EDE-Q), Beck Depression Inventory, the State Anxiety Inventory for Children, and the Maudsley Obsessive Compulsive Inventory. RESULTS: No significant difference was observed in the EDE-Q scores or the ED examination questionnaire scores between the initial (T1) and subsequent (T2) study. The ED-related quality of life was seen to have slightly improved in the later stage. While depression (T1: 18, T2: 15, p=0.883) and obsession scores (T1: 11, T2: 14, p: 0.536) showed no disparity between the studies, anxiety scores (T1: 38, T2: 43, p:0.011) exhibited a significant increase. CONCLUSIONS: Consistent with the early phase, no exacerbation of ED symptoms in adolescents was observed during the later stages of the pandemic. Close clinical monitoring during the pandemic might have been protective against the deteriorating effects of the pandemic. During social isolation, it is important to monitor adolescents with EDs continously for depression and anxiety.

Impulsivity in adolescent girls diagnosed with trichotillomania: an evaluation of clinical and neuropsychological characteristics.

The aim of this study is to compare the clinical and neuropsychological features of impulsivity in adolescent girls with trichotillomania (TTM) and healthy controls, and to assess the relationships between the severity of TTM and the impulsivity/concomitant symptoms of anxiety and depression. The study sample consisted of 43 adolescent girls who were 12 to 18 years old. The Kiddie-Schedule for Affective Disorders and Schizophrenia for School Age Children-Present and Lifetime Version DSM-5 (K-SADS-PL) was administered to the adolescents and their parents. All of the participants completed a sociodemographic data form, the Revised Children's Anxiety and Depression Scale-Child Version (RCADS-CV), the Barratt Impulsiveness Scale-Brief (BIS-Brief), and the Massachusetts General Hospital Hairpulling Scale (MGH-HPS). The Eriksen Flanker task, the Stop Signal Reaction Time (SSRT) task, the Go/No-Go task, and the Balloon Analog Risk Task (BART) were used to assess behavioral impulsivity. The adolescents with TTM reported higher levels of impulsivity and anxiety/depression symptoms than the healthy controls, and they also performed worse on the behavioral tasks. While there were no relationships between clinical and behavioral impulsivity and TTM severity, social anxiety symptoms were the most important predictor of the severity of TTM. It seems important to better understand the role of impulsivity in the onset and persistence of TTM symptoms in adolescents.

Neural correlates of distorted body images in adolescent girls with anorexia nervosa: How is it different from major depressive disorder?

Body image disturbance is closely linked to eating disorders including anorexia nervosa (AN). Distorted body image perception, dissatisfaction and preoccupation with weight and shape are often key factors in the development and maintenance of these disorders. Although the pathophysiological mechanism of body image disorder is not yet fully understood, aberrant biological processes may interfere with perceptive, cognitive and emotional aspects of body image. This study focuses on the neurobiological aspects of body image disturbance. The sample consisted of 12 adolescent girls diagnosed with AN, nine girls with major depressive disorder (MDD) and 10 without psychiatric diagnoses (HC, the healthy control group). We applied a block-design task in functional magnetic resonance imaging using participants' original and distorted overweight and underweight images. After imaging, the participants scored the images for resemblance, satisfaction and anxiety levels. The findings of this study demonstrate that overweight images elicited dissatisfaction and increased occipitotemporal activations across all participants. However, no difference was found between the groups. Furthermore, the MDD and HC groups showed increased activations in the prefrontal cortex and insula in response to underweight images compared to their original counterparts, whereas the AN group exhibited increased activations in the parietal cortex, cingulate gyrus and parahippocampal cortex in response to the same stimuli.

Body Focused Repetitive Behavior Disorders: Behavioral Models and Neurobiological Mechanisms. / Beden Odakli Tekrarlayici Davranis Bozukluklari: Davranis Modelleri ve Nörobiyolojik Mekanizmalar.

OBJECTIVE: Body Focused Repetitive Behaviors (BFRB) is an umbrella term for undesirable, repetitive motor activities such as Trichotillomania (TTM), Skin Picking Disorder (SPD), nail biting, cheek chewing, lip biting, finger sucking, finger cracking and teeth grinding. Such behaviors are engaged in to eliminate a part of the body and may result in impaired functionality. The frequency of presentation to clinicians is low since BFRB are defined as harmless, although the number of studies on this condition has increased rapidly recently, including those making a clear determination of epidemiological data, those investigating the etiopathogenesis and those providing treatment guidelines, although they remain inadequate. The present study provides a review of studies investigating the etiology of BFRB to date. METHOD: Articles published between 1992 and 2021 stored in the Pubmed, Medline, Scopus and Web of Science databases were reviewed, and the prominent research studies of the condition identified were included in the evaluation. RESULTS: Studies investigating the etiopathogenesis of BFRB were found in most cases to investigate adult populations, and were hampered by such confounding factors as clinical heterogeneity, high rates of comorbid psychiatric diseases and small sample sizes. The identified studies reveal that attempts have been made to explain BFRB based on behavioral models, and that the condition is inherited at a high rate. Treatment planning is mostly associated with monoamine systems (especially glutamate and dopamine) and interventions were directed to addiction elements. Furthermore, cognitive flexibility and motor inhibition defects in neurocognitive area and cortico-striato-thalamocortical cycle abnormalities in neuroimaging studies have been reported. CONCLUSION: Studies investigating the clinical features, incidence, etiopathogenesis and treatment of BFRB, which holds a controversial place in psychiatric classification systems, would contribute to a better understanding of the disease and a more appropriate definition of the condition.

The effects of the COVID-19 lockdown on adolescents with an eating disorder and identifying factors predicting disordered eating behaviour.

AIM: To evaluate the impact of the COVID-19 lockdown on adolescents with eating disorders (ED) and identify factors predicting ED behaviour. METHOD: This study took place during an age-stratified lockdown for those under 20 years in Turkey. Participants completed a survey developed to evaluate the effects of the lockdown on ED behaviour, well-being and quality of life (QoL) and additionally the eating disorder examination questionnaire (EDE-Q), and scales for depression, anxiety and obsessive-compulsive behaviour. The relationship between the EDE-Q-global score and other variables related to ED was examined. Linear regression analysis was performed to examine the predictive power of these variables on ED behaviour. RESULTS: Thirty-eight ED patients with a mean age of 15.12 ± 1.56 years were included in the study. Of participants, 42.1% reported feeling an improvement in ED symptomatology, 71.0% reported none or rare conflict with parents due to eating, 39.5% reported often or always complying with their meal plan. Of participants, 92.0% agreed to 'understanding the value of being healthy' and stated realizing that 'they were in control' due to the pandemic. Of participants 36.9% scored 'bad' for both overall and ED related QoL. In the stepwise regression analysis depression score had the highest predictive value for ED behaviour. CONCLUSION: Almost half of the participants felt an improvement in their ED and a majority reported rare parental conflict. However, less than half reported meal plan compliance. As depression had the highest positive predictive value for ED behaviour additional screening for depression during the pandemic maybe warranted in ED patients.

Effect of Impairment on the Prevalence and Comorbidities of Attention Deficit Hyperactivity Disorder in a National Survey: Nation-Wide Prevalence and Comorbidities of ADHD.

OBJECTIVE: This study aimed to determine the prevalence and comorbidities of attention-deficit hyperactivity disorder (ADHD) by evaluating a large-scale nation-wide sample of children. METHOD: The inclusion criterion was being enrolled as a 2nd, 3rd, or 4th-grade student. A semi-structured diagnostic interview (K-SADS-PL), DSM-IV-Based Screening Scale for Disruptive Behavior Disorders, and assessment of impairment (by both parents and teachers) were applied to 5,842 participants. RESULTS: The prevalence of ADHD was 19.5% without impairment and 12.4% with impairment. Both ADHD with and without impairment groups had similar psychiatric comorbidity rates except for oppositional defiant disorder (ODD) and conduct disorder (CD) diagnoses. Impairment in the ADHD group resulted in significantly higher ODD and CD diagnoses. CONCLUSION: Even when impairment is not described, other psychiatric disorders accompany the diagnosis of ADHD and may cause impairment in the future. Impairment in the diagnosis of ADHD significantly increases the likelihood of ODD and CD.

Mindful Eating, Body Weight, and Psychological Well-Being in Adolescence.

Background: This study investigated the relationships among psychological well-being, mindful eating, and weight in adolescents. Methods: Data of this cross-sectional study were collected from students of three high schools. Various questionnaires regarding mindful eating, eating behavior, emotion regulation, self-esteem, coping, body attitude, depression, and anxiety were given. BMI percentile was calculated and four groups were detemined. Hacettepe University Non-Inventional Clinical Researches Review Board approved the study (GO 18/1116). Results: Among 401 participants (59.1% girls), 16 adolescents (4.0%) were underweight, 295 (73.6%) were normal, 62 (15.5%) were overweight, and 28 (7.0%) were obese. Emotional and external eating were more common in girls. Restrictive eating was distinguishing between all adolescents, except ones with obesity and overweight. Adolescents with obesity perceived themselves as the least self-confident, attractive, and healthy, while the opposites were true for adolescents with normal weight. The groups that differed mostly from each other were normal weight and overweight. Conclusions: The psychological well-being of being overweight should not be underestimated. Emotional and external eating were correlated with low mindful eating, and gender differences were found in different aspects of mindful eating types. Calorie information and healthy eating interventions may be beneficial in boys, while interventions targeting to understand physical and emotional states may be beneficial in girls during the treatment of disordered eating behaviors.

Autistic Traits and Social Responsiveness: The Relationship Between Autistic Traits and Comorbid Psychiatric Symptoms in Adolescents with Anorexia Nervosa.

INTRODUCTION: It is known that patients with anorexia nervosa (AN) display social difficulties like social responsiveness and high levels of autistic behaviors such as rigidity, narrow interests of food and weight; however it is not clear whether they have comorbid Autism Spectrum Disorders (ASD) or it is about acute phase of illness. In this study it is aimed to investigate autistic traits and social responsiveness in adolescents with AN. METHODS: Study group was consisted of 39 female AN patients aged between 12-18 years. Control group was consisted of 34 female adolescents who did not have any psychiatric disorder. K-SADS-PL was applied to all participants in order to detect the psychiatric disorders. Autism traits and social responsiveness were evaluated using Social Responsiveness Scale. All adolescents of the study were administered The Eating Attitude Test, Beck Depression Inventory, Screen for Child Anxiety and Related Disorders, Maudsley Obsesive Compulsive Inventory. RESULTS: Results of the study indicated that adolescents with AN had higher symptoms of depression, anxiety and autism-like symptom clusters; and lower social responsiveness. Psychiatric comorbidities were not associated with these difficulties. CONCLUSION: The results show that AN patients have an impairment of social responsiveness, the impairment seems to be associated with AN regardless of psychiatric comorbidities. Despite these two disorders are considered unrelated, they have several traits in common. These results suggest that there may be a common pathogenesis between ASD and AN.

Attachment Security and Perceived Expressed Emotion in Adolescents with Anorexia Nervosa. / Anoreksiya Nervoza Tanisi Alan Ergenlerde Algilanan Duygu Disavurumu ve Baglanma Güvenligi.

OBJECTIVE: The aim of this study was to compare the attachment security and perceived expressed emotion of female adolescents diagnosed with anorexia nervosa and those without any psychiatric disorder and to compare the expressed emotion of their parents. We also aimed to investigate the relationships between these variables and the effects of depression and anxiety symptoms of the adolescents on attachment security, perceived expressed emotion and expressed emotion of the parents. METHOD: The study enrolled 43 female adolescents aged 12-18 years diagnosed with anorexia nervosa and an age and economic statusmatched control group of 37 healthy female adolescents. Both groups completed the Eating Attitudes Test-40 (EAT-40), the Perceived Expressed Emotion Scale (PEES), the Short Form of Inventory of Parentand Peer Attachment (IPPA), the Beck Depression Inventory (BDI) and the Screenfor Child Anxietyand Related Disorders (SCARED). Parents were assessed with the Expressed Emotion Scale (EES). RESULTS: As compared to the control group, the female adolescents with anorexia nervosa had lower attachment security and higher perception of parental expression of criticism and hostility. Presence of depression and anxiety symptoms did not affect these results. The security of maternal attachment in the adolescents with anorexia nervosa predicted their perception of criticism and hostility in their mothers. CONCLUSION: The results of this study indicate the importance of assessing attachment security and perceived expressed emotion in adolescents with anorexia nervosa and the requirement of parental inclusion in the therapeutic process during follow up for implementation of appropriate interventions.

Emotion regulation, emotion recognition, and empathy in adolescents with anorexia nervosa.

PURPOSE: Emotional functions may play an important role in anorexia nervosa (AN). The onset of the disorder generally occurs during adolescence, which is a critical period of emotional development. However, most studies that evaluated emotional functions in AN were conducted in adult patients. The aim of this study was to evaluate emotion regulation, emotion recognition, and empathy skills in adolescent girls with AN by controlling for the effects of depression and anxiety symptoms, childhood traumatic experiences, and attachment security on emotional functions. METHODS: Thirty-two adolescent girls with AN and 32 healthy counterparts completed the Difficulties in Emotion Regulation Scale, the Reading the Mind in the Eyes Test, Toronto Alexithymia Scale-20, and the Child and Adolescent KA-SI Empathic Tendency Scale-Adolescent Form. RESULTS: The results revealed that adolescents with AN were found to have more difficulties in emotion regulation, higher alexithymic tendencies, and lower empathy skills compared with the control group. However, emotion recognition was not found to be significantly different between the two groups. These results were the same when controlling for the effects of depression and anxiety symptoms, childhood traumatic experiences, and attachment security except for empathy skills. Alexithymia and depressive symptoms were significantly related to emotion regulation difficulties in adolescents with AN. CONCLUSIONS: Considering the results, it seems that emotion regulation and alexithymia may play a crucial role in the development and maintenance of AN. Accordingly, it is necessary to focus on the improvement of these skills during the treatment of AN. Furthermore, interventions promoting these skills during adolescence may be preventive. LEVEL OF EVIDENCE: Level III, case-control study.

[Childhood Traumas, Attachment and Alexithymia in Adolescentswith Psychogenic Nonepileptic Seizure Type of Conversion Disorder]. / Psikojenik Nöbet Tipinde Konversiyon Bozuklugu Olan Ergenlerde Çocukluk Çagi Travmalari, Baglanma ve Aleksitimi.

OBJECTIVE: In this cross-sectional study, childhood traumas, attachment security and alexithymia in adolescents with psychogenic nonepileptic seizures (PNES) were compared with those of adolescents without any psychiatric disorder using both semi-structured clinical interviews and self-report scales. METHOD: This study included 42 adolescents with PNES aged between 12-18 and 38 healthy adolescents who were matched with the study group in respect to socio-demographic variables. All adolescents and their parents were interviewed using Schedule for Affective Disorders and Schizophrenia for School-Age Children-Present and Lifetime Version in order to evaluate psychiatric disorders. Clinician- Administered Posttraumatic Stress Disorder (PTSD) Scale for Children and Adolescents was used to examine the presence of PTSD symptoms. All adolescents completed the Childhood Trauma Questionnaire-28, Short Form of Inventory of Parent and Peer Attachment, Toronto Alexithymia Scale and Rosenberg Self Esteem Scale. RESULTS: Adolescents with PNES had more emotional and sexual traumatic experiences and PTSD symptoms compared to the control group. PNES group perceived higher "communication" but lower "trust" in attachment relationships with their mothers and fathers. Higher alexithymia and lower self-esteem were determined in the PNES group. Childhood traumas, lifetime PTSD symptoms and alexithymia were found to be significant risk factors for PNES in adolescents. CONCLUSION: Results indicate that comorbid psychiatric disorders, traumatic experiences, attachment problems and alexithymia need to be evaluated and treated in adolescents with PNES.

[Reliability and Validity of the Schedule for Affective Disorders and Schizophrenia for School-Age Children-Present and Lifetime Version, DSM-5 November 2016-Turkish Adaptation (K-SADS-PL-DSM-5-T)]. / Okul Çagi Çocuklari için Duygulanim Bozukluklari ve Sizofreni Görüsme Çizelgesi–Simdi ve Yasam Boyu Sekli–DSM–5 Kasim 2016 –Türkçe Uyarlamasinin (ÇDSG–SY–DSM–5–T) Geçerlik ve Güvenirligi.

OBJECTIVE: The aim of this study was to evaluate the reliability and validity of the Schedule for Affective Disorders and Schizophrenia for School-Age ChildrenPresent and Lifetime Version, DSM-5 November 2016 -Turkish Adaptation (K-SADS-PL-DSM-5-T).  METHOD: A total of 150 children and adolescents between 6 and 17 years of age were assessed with K-SADS-PL-DSM-5-T. The degree of agreement between the DSM-5 criteria diagnoses and the K-SADS-PL-DSM-5-T diagnoses were considered as the measure of consensus validity. In addition, concurrent validity was examined by analyzing the correlation between the diagnoses on K-SADS-PL-DSM-5-T and relevant scales. Interrater reliabilities were assessed on randomly selected 20 participants. Likewise, randomly selected 20 other participants were interviewed with K-SADS-PL-DSM-5-T three weeks after the first interview to evaluate test-retest reliability.  RESULTS: The consistency of diagnoses was almost perfect for eating disorders, selective mutism and autism spectrum disorder (κ=0.92-1.0), substantial for elimination disorders, obsessive-compulsive disorder, oppositional defiant disorder, generalized anxiety disorder, social anxiety disorder, depressive disorders, disruptive mood dysregulation disorder and attention deficit hyperactivity disorder (κ=0.67-0.80). Interrater reliability was perfect for selective mutism (κ=1.0), substantial for oppositional defiant disorder, disruptive mood dysregulation disorder, attention deficit hyperactivity disorder, depressive disorders and social anxiety disorder (κ=0.63-0.73). Test-retest reliability was almost perfect for autism spectrum disorder (κ=0.82), substantial for attention deficit hyperactivity disorder, oppositional defiant disorder, disruptive mood dysregulation disorder, depressive disorders and generalized anxiety disorder (κ=0.62-0.78).  CONCLUSION: The results of this study show that the K-SADS-PL-DSM-5-T is an effective instrument for diagnosing major childhood psychiatric disorders including selective mutism, disruptive mood dysregulation disorder and autism spectrum disorder which have recently been added to the schedule.

The prevalence of childhood psychopathology in Turkey: a cross-sectional multicenter nationwide study (EPICPAT-T).

AIM: The aim of this study was to determine the prevalence of childhood psychopathologies in Turkey. METHOD: A nation-wide, randomly selected, representative population of 5830 children (6-13 years-old) enrolled as a 2nd,3rd or 4th grade student in 30 cities were evaluated for presence of a psychiatric or mental disorder by a Sociodemographic Form, Kiddie Schedule for Affective Disorders and Schizophrenia for School Age Children-Present and Lifetime Version (K-SADS-PL), and DSM-IV-Based Screening Scale for Disruptive Behavior Disorders in Children and Adolescents scales. Impairment criterion was assessed via a 3 point-Likert scale by the parent and the teacher independently. RESULTS: Overall prevalence of any psychopathology was 37.6% without impairment criterion, and 17.1% with impairment criterion. Attention-deficit hyperactivity disorder was the most frequent diagnosis, followed by anxiety (19.5% and 16.7% without impairment, 12.4% and 5.3% with impairment, respectively). Lower education level and presence of a physical or psychiatric problem of the parents were independent predictors of any psychopathology of the offspring. CONCLUSION: This is the largest and most comprehensive epidemiological study to determine the prevalence of psychopathologies in children and adolescents in Turkey. Our results partly higher than, and partly comparable to previous national and international studies. It also contributes to the literature by determining the independent predictors of psychopathologies in this age group.

Parenting styles, perceived social support and emotion regulation in adolescents with internet addiction.

AIM: The aim of this study is to investigate parental attitudes, perceived social support, emotion regulation and the accompanying psychiatric disorders seen in adolescents who, having been diagnosed with Internet Addiction (IA), were referred to an outpatient child and adolescent psychiatric clinic. METHODS: Of 176 adolescents aged 12-17, 40 were included in the study group. These scored 80 or higher on Young's Internet Addiction Test (IAT) and met Young's diagnostic criteria for IA based on psychiatric interviews. Forty adolescents who matched them in terms of age, gender and socio-economic level were included in the control group. The Schedule for Affective Disorders and Schizophrenia for School-Age Children (K-SADS-PL), the Parenting Style Scale (PSS), the Lum Emotional Availabilty of Parents (LEAP), the Social Support Appraisals Scale for Children (SSAS-C), the Difficulties in Emotion Regulation Scale (DERS) and the Toronto Alexithymia Scale-20 (TAS-20) were applied. RESULTS: The results showed that the parents of adolescents with IA were more frequently inadequate in acceptance/involvement, supervision/monitoring and they had less emotional availability. The adolescents with IA had less perceived social support, greater difficulty in the identification and verbal expression of their feelings and emotion regulation. Lower parental strictness/supervision, higher alexithymia and the existence of an anxiety disorder were found to be significant predictors of IA. Internet addicted adolescents with comorbid major depressive disorder had higher levels of alexithymia and lower levels of emotional availability in their parents. CONCLUSION: It can be concluded that strategies for the prevention and treatment of IA in adolescents should focus on improving the quality of parenting parent-adolescent relationships, enhancing perceived social support and emotion regulation while reducing the associated psychiatric symptoms in adolescents.

Prevalence of Childhood Affective disorders in Turkey: An epidemiological study.

AIM: To determine the prevalence of affective disorders in Turkey among a representative sample of Turkish population. METHODS: This study was conducted as a part of the "The Epidemiology of Childhood Psychopathology in Turkey" (EPICPAT-T) Study, which was designed by the Turkish Association of Child and Adolescent Mental Health. The inclusion criterion was being a student between the second and fourth grades in the schools assigned as study centers. The assessment tools used were the K-SADS-PL, and a sociodemographic form that was designed by the authors. Impairment was assessed via a 3 point-Likert type scale independently rated by a parent and a teacher. RESULTS: A total of 5842 participants were included in the analyses. The prevalence of affective disorders was 2.5 % without considering impairment and 1.6 % when impairment was taken into account. In our sample, the diagnosis of bipolar disorder was lacking, thus depressive disorders constituted all the cases. Among depressive disorders with impairment, major depressive disorder (MDD) (prevalence of 1.06%) was the most common, followed by dysthymia (prevalence of 0.2%), adjustment disorder with depressive features (prevalence of 0.17%), and depressive disorder-NOS (prevalence of 0.14%). There were no statistically significant gender differences for depression. Maternal psychopathology and paternal physical illness were predictors of affective disorders with pervasive impairment. CONCLUSION: MDD was the most common depressive disorder among Turkish children in this nationwide epidemiological study. This highlights the severe nature of depression and the importance of early interventions. Populations with maternal psychopathology and paternal physical illness may be the most appropriate targets for interventions to prevent and treat depression in children and adolescents.

Predictors of self-esteem in adolescents with a psychiatric referral.

In the literature self-esteem is found to be lower in clinically referred adolescents compared to adolescents without any psychiatric disorder. The aim of this study is to examine self-esteem and associated socio-demographical and psychological factors in clinically referred adolescents in Turkey. Three hundred forty-nine adolescents aged between 12 and 18 years admitted to the Department of Child and Adolescent Psychiatry with a psychiatric complaint were enrolled. Rosenberg Self-Esteem Scale (RSES), Brief Symptom Inventory (BSI), Parenting Style Scale (PSS) and Sense of Identity Assessment Form (SIAF) were used for the evaluation. Self-esteem was lower in: girls, adolescents without siblings, living in non-nuclear families, with a past suicide attempt, and with history of a non-suicidal self-injurious behavior (NSSI). Self-esteem was negatively correlated with identity confusion on SIAF and positively correlated with acceptance/involvement on PSS. Significant predictors of self-esteem were gender, presence of a sibling, history of a NSSI and SIAF scores. Interactions between self-esteem and gender, psychiatric symptoms, parenting and identity development are complex in clinically referred adolescents. Further elucidation of the mechanisms through which these characteristics modify self-esteem will be necessary to guide families and clinicians to help adolescents to maintain high self-esteem levels.

[Neurobiology of Tourette Syndrome]. / Tourette Sendromunun Nörobiyolojisi.

Tourette Syndrome (TS) is a neurodevelopmental disorder characterized by chronic motor and vocal tics. Although it is a common disorder in childhood, the etiology of Tourette Syndrome has not been fully elucidated yet. Studies, -conducted so far- have revealed differences in neurobiological structures of individuals who suffer from Tourette Syndrome. The objective of this review is to assess etiological and pathophysiological studies in the Tourette Syndrome literature. An electronical search was conducted in PubMed database using the keywords tic disorders, Tourette Syndrome, neurobiology, genetics, neuroimaging and animal models. Research and review studies published between 1985 and 2015, with a selection preference towards recent publications, were reviewed. According to the studies, genetic predisposition hypothesis is considered as a priority. However, a precise genetic disorder associated with Tourette Syndrome has not been found. The evidence from postmortem and neuroimaging studies in heterogenous patient groups and animal studies supports the pathological involvement of cortico-striato-thalamo-cortical (CSTC) circuits in Tourette Syndrome. Consequently, the most emphasized hypothesis in the pathophysiology is the dopaminergic dysfunction in these circuits. Furthermore, these findings of the animal, postmortem and neuroimaging studies have confirmed the neurodevelopmental hypothesis of Tourette Syndrome. In conclusion, more studies are needed to understand the etiology of the disorder. The data obtained from neurobiological studies of the disorder will not only shed light on the way of Tourette Syndrome, but also guide studies on its treatment options.

Gender differences in defense mechanisms, ways of coping with stress and sense of identity in adolescent suicide attempts.

The main aim of this study was to investigate the gender differences in defense mechanisms, ways of coping with stress and identity formation in relation to adolescent suicidal behavior. This study involved 64 adolescents between 12-17 years of age, who were admitted to the emergency service with a suicide attempt. They were evaluated with a semi-structured clinical interview (K-SADS), Ways of Coping Inventory (WCI), Defense Mechanisms Inventory (DMI) and Sense of Identity Assessment Form (SIAF). 60.9% (n = 39) of the adolescents were female, and 39.1% (n=25) were male. There were no statistically significant differences between the girls and the boys with respect to the clinical characteristics of the suicide attempt and the rate of psychiatric disorders. Of the 64 adolescents with suicide attempt, 47 (73.4%) had at least one, and 26 (40.6%) had more than one psychiatric disorder according to K-SADS. Disruptive behavior disorders were more frequent in males, whereas depression was more frequent in girls. The data indicated the importance of identity confusion, major depression and ADHD in adolescents with suicide attempt in both genders. 43.6% (n=17) of the girls and 36% (n=9) of the boys obtained scores higher than the cut-off point of SIAF indicating identity confusion. Professional help seeking and NSSI behaviors before the suicide attempt were more common in adolescents with identity confusion. While there were differences between genders with respect to the defense mechanisms used, no significant difference was found in terms of ways of coping. Evaluation of DMI scores revealed that the turning against object subscale score was significantly higher in boys compared to girls. While evaluating the adolescents at risk, their defense mechanisms, way of coping and sense of identity, as well as their psychiatric diagnosis should be assessed in detail in order to identify the suicidal thoughts and prevent possible suicide attempts.

The understanding of risk factors for eating disorders in male adolescents.

OBJECTIVE: The study aimed to describe the medical, psychiatric, and cultural features of adolescent males with an eating disorder (ED). MATERIALS AND METHODS: This retrospective evaluation took place at Hacettepe University, Ihsan Dogramaci Children's Hospital, Ankara, Turkey, and covered a 4-year period between 2010 and 2013. Sixty adolescents were diagnosed with an ED during this period, 47 (78.3%) were females and 13 were males (21.7%) male. All 13 male patients who met full criteria for an ED according to the DSM criteria were included. Medical and psychiatric records of male patients treated for an ED were re-evaluated. RESULTS: The most striking finding of the study was that the female to male ratio became 3.6:1, with the increasing number of male adolescents with an ED. In our study, medical findings and complications of males with ED were similar to those seen in females. However, the most predominant gender difference was the co occurrence of a comorbid physical or mental illness. CONCLUSION: It is imperative to raise awareness of EDs in males. Although the medical findings of the study suggest that male and female adolescents with EDs are clinically similar to each other, the understanding of certain gender-specific risk factors shown in our study, such as a medical illness and/or obesity and co-morbid psychiatric diagnosis, are essential in raising suspicion. Further studies that especially evaluate cultural and social factors that affect parenting styles for boys are important in addessing possible risk factors for the development of EDs in males within different societies.
