However, the potential adaptability of procrastination, largely considered as a maladaptive construct, and its possible developmental connection to perfectionism remains unclear. The purpose of this study was to examine the individual differences of the multidimensional models of both perfectionism and procrastination, as well as investigating potential links between the two constructs. Methods: A convenience sample of 206 undergraduate students participated in this study. Participants completed a questionnaire consisting of 236 questions regarding the variables under investigation. Results: The adaptive model of procrastination yielded largely insignificant results and demonstrated limited links with adaptive perfectionism, while maladaptive procrastination was consistently associated with maladaptive perfectionism, lending further evidence of a unidimensional model of

  • Decreased Empathy Response to Other People's Pain in Bipolar
    www.nature.com/scientificreports OPEN Decreased empathy response to other people’s pain in bipolar disorder: evidence from an event- Received: 28 June 2016 Accepted: 29 November 2016 related potential study Published: 06 January 2017 Jingyue Yang1,2,3,*, Xinglong Hu3,*, Xiaosi Li3, Lei Zhang1,2,4, Yi Dong3, Xiang Li5, Chunyan Zhu1,2,4, Wen Xie3, Jingjing Mu3, Su Yuan3, Jie Chen3, Fangfang Chen1,2,4, Fengqiong Yu1,2,4,* & Kai Wang6,1,2,4,* Bipolar disorder (BD) patients often demonstrate poor socialization that may stem from a lower capacity for empathy. We examined the associated neurophysiological abnormalities by comparing event-related potentials (ERP) between 30 BD patients in different states and 23 healthy controls (HCs, matched for age, sex, and education) during a pain empathy task. Subjects were presented pictures depicting pain or neutral images and asked to judge whether the person shown felt pain (pain task) and to identify the affected side (laterality task) during ERP recording. Amplitude of pain-empathy related P3 (450–550 ms) of patients versus HCs was reduced in painful but not neutral conditions in occipital areas [(mean (95% confidence interval), BD vs. HCs: 4.260 (2.927, 5.594) vs. 6.396 (4.868, 7.924)] only in pain task. Similarly, P3 (550–650 ms) was reduced in central areas [4.305 (3.029, 5.581) vs. 6.611 (5.149, 8.073)]. Current source density in anterior cingulate cortex differed between pain-depicting and neutral conditions in HCs but not patients. Manic severity was negatively correlated with P3 difference waves (pain – neutral) in frontal and central areas (Pearson r = −0.497, P = 0.005; r = −0.377, P = 0.040).

Recent evidence indicates associations between this atypical functioning and the presence of neurally-based anomalies. This article critically reviews the literature on two types of core socio- emotional skills that may represent endophenotypes for BD, with a focus on differences between individuals with BD, both youth and adults, and their typically developing peers.

  • Young Mania Rating Scale (YMRS)
    PATIENT EDUCATION TOOLS Young Mania Rating Scale (YMRS) OVERVIEW The Young Mania Rating Scale (YMRS) is one of the most frequently utilized rating scales to assess manic symptoms. The scale has 11 items and is based on the patient’s subjective report of his or her clinical condition over the previous 48 hours. Additional information is based upon clinical observations made during the course of the clinical interview. The items are selected based upon published descriptions of the core symptoms of mania. The YMRS follows the style of the Hamilton Rating Scale for Depression (HAM-D) with each item given a severity rating. There are four items that are graded on a 0 to 8 scale (irritability, speech, thought content, and disruptive/aggressive behavior), while the remaining seven items are graded on a 0 to 4 scale. These four items are given twice the weight of the others to compensate for poor cooperation from severely ill patients. There are well described anchor points for each grade of severity. The authors encourage the use of whole or half point ratings once experience with the scale is acquired. Typical YMRS baseline scores can vary a lot. They depend on the patients’ clinical features such as mania (YMRS = 12), depression (YMRS = 3), or euthymia (YMRS = 2). Sometimes a clinical study entry requirement of YMRS > 20 generates a mean YMRS baseline of about 30. Strengths of the YMRS include its brevity, widely accepted use, and ease of administration. The usefulness of the scale is limited in populations with diagnoses other than mania. The YMRS is a rating scale used to evaluate manic symptoms at baseline and over time in individuals with mania.

  • Haematological and Biochemical Differences Between Mania and Euthymia
    Eur. J. Psychiat. Vol. 30, N.° 3, (163-171) 2016 Keywords: Mania; Inflammation; Haemodilution. Haematological and biochemical differences between mania and euthymia Köse Çinar Rugüla,* Görgülü Yasemina Sönmez Mehmet Bülenta Kahyaci Kiliç Evnurb a Assistant Professor, MD, Department of Psychiatry, Trakya University Faculty of Medicine, Edirne b MD, Department of Psychiatry, Trakya University Faculty of Medicine, Edirne TURKEY ABSTRACT – Background and Objectives: The effects of transient hypothalamic dys- function on the hypothalamic-pituitary-adrenal and hypothalamic-pituitary-thyroid axes can be shown by haematological and biochemical parameter changes. We hypothesized that manic episodes will be associated with subclinical inflammation, haemodilution and altered thyroid functions compared to euthymic states. Methods: Patients admitted to the psychiatry clinic with manic episodes were identified. Those having comorbidities, except for thyroid dysfunctions, hypertension, hyperlipidemia, and type 2 diabetes mellitus, were excluded. Complete blood counts, total protein, albumin, and thyroid tests were recorded during the admissions (manic episodes) (Maletic, 2014 #24) and one year later (euthymic states) for the same patients. Results: All studied parameters had significant differences between mania and euthymia. During manic episodes, patients had higher peripheral inflammatory indices (neutrophil/lym- phocyte ratio and platelet/lymphocyte ratio), haemodilution (lower haemoglobin, haemat- ocrit, total protein, and albumin), higher thyroxine and lower thyroid-stimulating hormone levels compared to euthymic states. Conclusions: This study supports the hypothesis that compared to euthymic states; manic episodes are associated with low-grade inflammation, haemodilution and thyroid function abnormalities. Monitoring patients’ blood compositions could result in better prognostic evaluations and aid in determining additional systemic treatment options, as well as in generating causal hypothesis to be tested in future studies.

Two scenes were simultaneously presented (happy/threatening/neutral Mood-congruent biases [target] versus control). Participants were asked either to look at the emotional pictures (i.e., attend-to- Attention emotional block) or to avoid looking at the emotional pictures (i.e., attend-to-neutral block) while their eye Inhibitory control movements were recorded. The initial orienting (latency and percentage of first fixation) and subsequent Bipolar disorder attentional engagement (gaze duration) were computed. Manic patients showed a higher percentage of initial fixations on happy scenes than on the other scenes, regardless of the instructions. However, in the attend-to- neutral block, their gaze durations were longest for threatening scenes. Inhibitory control was not modulated by the scene's emotional salience in the other groups. Thus, manic patients had difficulties voluntarily ignoring emotional information – this was characterized by a happy-related bias during initial orienting, but a threat- related bias during attentional engagement.

  • Intrusive Images in Psychological Disorders: Characteristics, Neural Mechanisms, and Treatment Implications
    Psychological Review © 2010 American Psychological Association 2010, Vol. 117, No. 1, 210–232 0033-295X/10/$12.00 DOI: 10.1037/a0018113 Intrusive Images in Psychological Disorders: Characteristics, Neural Mechanisms, and Treatment Implications Chris R. Brewin, James D. Gregory, Michelle Lipton, and Neil Burgess University College London Involuntary images and visual memories are prominent in many types of psychopathology. Patients with posttraumatic stress disorder, other anxiety disorders, depression, eating disorders, and psychosis fre- quently report repeated visual intrusions corresponding to a small number of real or imaginary events, usually extremely vivid, detailed, and with highly distressing content. Both memory and imagery appear to rely on common networks involving medial prefrontal regions, posterior regions in the medial and lateral parietal cortices, the lateral temporal cortex, and the medial temporal lobe. Evidence from cognitive psychology and neuroscience implies distinct neural bases to abstract, flexible, contextualized representations (C-reps) and to inflexible, sensory-bound representations (S-reps). We revise our previ- ous dual representation theory of posttraumatic stress disorder to place it within a neural systems model of healthy memory and imagery. The revised model is used to explain how the different types of distressing visual intrusions associated with clinical disorders arise, in terms of the need for correct interaction between the neural systems supporting S-reps and C-reps via visuospatial working

  • Impaired Regulation of Emotion: Neural Correlates of Reappraisal and Distraction in Bipolar Disorder and Unaffected Relatives
    OPEN Citation: Transl Psychiatry (2015) 5, e497; doi:10.1038/tp.2014.137 www.nature.com/tp ORIGINAL ARTICLE Impaired regulation of emotion: neural correlates of reappraisal and distraction in bipolar disorder and unaffected relatives P Kanske1, S Schönfelder2, J Forneck3 and M Wessa2 Deficient emotion regulation has been proposed as a crucial pathological mechanism in bipolar disorder (BD). We therefore investigated emotion regulation impairments in BD, the related neural underpinnings and their etiological relevance for the disorder. Twenty-two euthymic patients with bipolar-I disorder and 17 unaffected first-degree relatives of BD-I patients, as well as two groups of healthy gender-, age- and education-matched controls (N = 22/17, respectively) were included. Participants underwent functional magnetic resonance imaging while applying two different emotion regulation techniques, reappraisal and distraction, when presented with emotional images. BD patients and relatives showed impaired downregulation of amygdala activity during reappraisal, but not during distraction, when compared with controls. This deficit was correlated with the habitual use of reappraisal. The negative connectivity of amygdala and orbitofrontal cortex (OFC) observed during reappraisal in controls was reversed in BD patients and relatives. There were no significant differences between BD patients and relatives. As being observed in BD patients and unaffected relatives, deficits in emotion regulation through reappraisal may represent heritable neurobiological abnormalities
