    L-Carnitine Use as a Trigger for the Onset of Kleine-Levin Syndrome: a Case Presentation
    (Klinik Psikiyatri Dergisi, 2022) Yaylaci, Ferhat; Kucuk, Onder; Erkuran, Handan Ozek
    Kleine- Levin Syndrome (KLS) is a rare phenomenon characterized by repeating episodes of hypersomnia, cognitive and behavioral impairments, compulsive eating behavior, and hypersexuality. Postinfectious processes, alcohol consumption, sleep deprivation, psychological stress, getting vaccinated, head injury and genetic factors have been identified possible etiological factors. Abnormal metabolism of serotonin and dopamine have also been reported. Alcohol and cannabis have been listed among triggering factors. With its role as a mediator required to transport long-chain fatty acids to mitochondrial matrix and its contributions in increasing oxidation of fatty acids, L-carnitine helps to produce more energy from burning fat while maintaining economic use of muscle glycogen stocks. Animal studies have shown a continous increase in dopamine discharge within nucleus accumbens via acetyl L-carnitine application. Carnitine supplementation is known to cause increased dopamine levels within cortical, hippocampal and striatal regions of the rat brain. One case report reported severe psychotic symptoms in a patient with bipolar disorder, following acetyl L-carnitine use. In this case presentation, we have aimed to present clinical course of an adolescent using L-carnitine for ergogenic support, as a possible trigger for the onset of a KLS episode.

    Increased Serum Levels of Nmda Receptor Antibodies in Female Patients With Bipolar Disorder
    (Klinik Psikiyatri Dergisi, 2018) Ceylan, Deniz; Akan, Pinar; Doyuran, Kerim; Can, Gunes; Ersen, Ayca; Misir, Emre; Ozerdem, Aysegul; Acar, Can M. Güneş; Özalp, Deniz Ceylan Tufan
    Objective: Glutamatergic/GABAergic imbalance due to autoimmune antibodies targeting N-methyl-D-aspartate receptors (NMDA-R) is considered to be one of the shared pathways between bipolar disorder (BD) and autoimmune diseases. Evidence shows female vulnerability to autoimmune disorders, and suggests a sex-specific approach in autoimmunity research in BD. We aimed to assess serum concentrations of NMDA-R antibodies and density of NMDA and GABA receptors on platelets in euthymic patients with BD in comparison to healthy individuals; and to determine the impact of sex on serum concentrations of NMDA-R antibodies and the density of NMDA and GABA receptors on platelets. Method: NMDA antibody IgG were detected in serum samples of 27 DSM IV euthymic patients with bipolar disorder (16 females, 11 males) and 33 healthy individuals (17 females, 16 males), using ELISA method. The densities of NMDA and GABA receptors on platelets were investigated using immunocytochemical methods. Results: Patients with BD presented higher serum levels of NMDA-R antibodies in comparison to healthy individuals (p < 0.001). The densities of NMDA and GABA receptor on platelets were similar in both groups. The NMDA-R antibody levels were influenced by both diagnosis and sex (F = 5.813, df = 1, p = 0.020). Tserum lithium levels showed a significant linear association with the serum NMDA-R antibody levels even adjusting for age, sex, body mass index (F = -56.26, t = -2.52, p = 0.015, CI: -101.12/-11.40). Discussion: Our findings support a potential role of NMDA-R antibodies in the underlying pathophysiology of BD, particularly for females.

    Turkish Adaptation and Validation of Behavioral Inhibition Questionnaire Parent Form
    (Aves, 2023-01-02) Kilinc, Saliha; Bilgiç, Ayhan; Gormez, Vahdet
    Background: Behavioral inhibition has been proposed as a temperamental risk factor for the development of childhood anxiety disorders universally; however, there is no validated instrument for, especially, its evaluation in Turkish children. This study aimed to examine reliability and validity of the Turkish version of Behavioral Inhibition Questionnaire parent form for children aged 3-7 years. Methods: Around 250 mothers or fathers of 3-7 years old children were recruited from non-clinical population to collect responses to the questionnaires. The sample was created by reaching 3 schools at preschool or elementary grade for the purpose of providing the questionnaires filled about the student and/or his/her little sisters and brothers by their parents; questionnaires were sent out to parents and then gathered. Parents were asked to fill sociodemographic data form, Behavioral Inhibition Questionnaire parent form, Children Behavior Questionnaire, and Strengths and Difficulties Questionaire parent form in order to perform convergent and divergent validity analyses. Results: As a result of reliability analysis, total Cronbach alpha coefficient for Behavioral Inhibition Questionnaire was determined as 0.92 with strong reliability. The internal consistency coefficients for Behavioral Inhibition Questionnaire subscales also showed strong reliability with alphas ranging between 0.81 and 0.87 except for the performance (a = 0.69) and physical challenges (a = 0.19) subscales of which some items were excluded due to item-total correlations and confirmatory factor analysis results. In the validity assessment analyses, confirmatory factor analysis demonstrated that Behavioral Inhibition Questionnaire has a construct validity with 5 factors loaded on the 2-second order main factors and one third-order final factor (root mean square error = 0.032, root mean square residual = 0.153, Comparative Fit Index = 0.978, Goodness of Fit Index = 0.915, and Turker-Lewis Index = 0.970). While the strongest correlations with the overall Behavioral Inhibition Questionnaire score were found for 2 main subscales, inhibition to social novelties (r = 0.926, P <.001) and situational novelties (r = 0.928, P <.001), similarly peers (r = 0.848, P <.001) and new situations (r = 0.898, P <.001) subscales, had strong correlations with the overall Behavioral Inhibition Questionnaire score. The weakest correlation with overall Behavioral Inhibition Questionnaire score was observed for physical challenges subscale even though this subscale displayed moderate association (r = 0.454, P <.001). A good convergent validity was determined accompanied by significant moderate positive correlations with Children Behavior Questionnaire shyness and Strengths and Difficulties Questionnaire internalizing scales. An adequate divergent validity was also demonstrated based on significant positive mild to moderate correlations with Children Behavior Questionnaire impulsivity, Children Behavior Questionnaire smiling/laugh, Strengths and Difficulties Questionnaire prosocial scales, and nonsignificant correlation with Strengths and Difficulties Questionnaire externalizing scale. Conclusion: The study demonstrated that the Turkish version of the Behavioral Inhibition Questionnaire parent form is an effective tool with good reliability and validity among 3-7 years old children.

    Innovations in Neurophysiology and Their Use in Neuropsychiatry
    (Turkish Neuropsychiatry Assoc-Turk Noropsikiyatri Dernegi, 2022) Yener, Görsev; Öz, Didem
    Many structural and functional tests are used to explore the nature of neurodevelopmental and neurodegenerative diseases. Cognitive involvement has become more and more remarkable in many neurological and psychiatric disorders. This condition evoked a paradigm shift, and today disorders are addressed from a neuroscientific perspective, including silent symptoms. The spatial resolution of structural studies is lacking and is combined with the unique temporal resolution of EEG methods. In our current clinical practice, EEG does not have definitive diagnostic value in psychiatric disorders, but it helps to make a correct diagnosis by excluding other neurological diseases. However, the use of EEG for research purposes is promising in both groups. In this review; there is up-to-date information on the use of electrophysiological examinations in neurological diseases, especially Alzheimer's disease, Parkinson's disease, Frontotemporal dementia, and psychiatric disorders such as schizophrenia, mood disorders, attention deficit and hyperactivity disorder, and obsessive-compulsive disorder, to define the point we have reached in our journey to understand these disorders.

    Senior Moments Are Never-Ending Times When You Are Old (are They?): First Step of Turquoise Project
    (Turkish Neuropsychiatry Assoc-Turk Noropsikiyatri Dernegi, 2022) Oz, Didem; Yildirim, Zerrin; Kiyi, Ilayda; Ozbek, Yagmur; Kulac, Ibrahim; Erkol, Gokhan; Tihan, Tarik; Yener, Görsev; Erkol, Gökhan; Gürvit, Hakan
    Introduction: The number of dementia patients is increasing in Turkey,, as well as all over the world. However, we do not know how much the society knows about dementia. The aim of this study is to evaluate people's concept of dementia, their awareness of dementia research and treatment, whether dementia and forgetfulness are considered normal in old age, and whether having dementia is associated with a lack of mental abilities. Methods: A Dementia Awareness Questionnaire was created in the form of a self-report questionnaire, consisting of 20 questions and using a five-point Likert-type answering method in order to question participants' information about dementia. In addition, we asked for demographic information such as age, gender, occupation, education level of the participants, as well as whether they have had relatives diagnosed with a neurodegenerative disease. The surveys were administered online. Results: A total of 1551 participants from 53 cities were included in the study. Approximately half of the participants did not know the definition of dementia, 20.9% thought that dementia and Alzheimer's disease were the same; 50.4% considered forgetfulness, and 55.2% considered dementia as a natural consequence of aging. While 34.5% of the participants thought that dementia patients could be dangerous, 10.3% thought they could not continue living as a part of society. While 38.5% of healthcare professionals do not know the definition of dementia, 18.5% of them say that dementia and Alzheimer's disease are the same, 58.5% think that dementia patients are not fit to make their own decisions, 40.6% believe that dementia patients have criminal liability. 15.8% of healthcare professionals thought that dementia is only seen in elderly people; 21.4% thought that dementia, and 49.2% thought that forgetfulness was a result of normal aging. Conclusion: Our study confirms that dementia is still an unknown concept in society and among healthcare professionals. It is widely believed that forgetfulness and dementia are part of normal aging, and there is no cure for dementia. This study, which we have done in order to understand the level of dementia awareness in Turkish society, reveals the necessity for research on dementia and studies on how to increase dementia awareness.
