This study adds to existing knowledge by examining the effect of major depressive disorder (MDD) on the sequential organization of information processing, executive and community functioning. Fifty-seven participants with 19 participants each for first episode depression (FMDD), recurrent episodes depression (RMDD), and healthy controls (HCs) participated in this study. They completed assessments on executive and community functioning measures, and choice reaction time task (CRTT) for the event-related potential (ERP) data. Findings revealed no significant between-group difference in executive functioning but participants with depression (FMDD and RMDD) were found to be more depressed, with FMDD participants having worse community functioning skills compared with HCs. There was no significant between-group main effect on behavioral data. ERP data showed significantly less positive-going P3b among RMDD participants compared with HCs. FMDD participants used a different information processing strategy at P1, while HCs and RMDD participants used a different processing strategy at N2b compared with the other group(s), respectively. The results suggest the use of multifaceted assessment to get a holistic view of the health status of people with MDD in order to inform clinicians on the appropriate interventional strategies needed for the patient. Keywords: major depressive disorder; information processing; executive function; community function; event-related potential; choice reaction time task; cognitive-energetical linear stage model; parallel model; linear model 1. Introduction Depression, especially major depressive disorder (MDD), has been reported to affect all facets of a patient’s life, particularly cognitive processes and functions. More specifically, perception, attention, inhibition, executive function, and memory were reported to be compromised [1–4]. It is also well documented in behavioral studies that MDD patients suffer impaired decision making or response choices during tasks which may be attributed to their inability to perform or psychomotor retardation [5,6]. Psychomotor retardation, a major symptom of depression, is associated with general slowness and poor performance [7] which can be separated from the effect of arousal or sleepiness [8–11]. Despite these findings, the effect of depression along information processing stages [12,13] remains poorly understood, Brain Sci. 2020, 10, 935; doi:10.3390/brainsci10120935 www.mdpi.com/journal/brainsci Brain Sci. 2020, 10, x FOR PEER REVIEW 2 of 19 Braingeneral Sci. 2020 slowness, 10, 935 and poor performance [7] which can be separated from the effect of arousal2 of 18or sleepiness [8–11].

  • Understanding the Mental Status Examination with the Help of Videos
    Understanding the Mental Status Examination with the help of videos Dr. Anvesh Roy Psychiatry Resident, University of Toronto Introduction • The mental status examination describes the sum total of the examiner’s observations and impressions of the psychiatric patient at the time of the interview. • Whereas the patient's history remains stable, the patient's mental status can change from day to day or hour to hour. • Even when a patient is mute, is incoherent, or refuses to answer questions, the clinician can obtain a wealth of information through careful observation. Outline for the Mental Status Examination • Appearance • Overt behavior • Attitude • Speech • Mood and affect • Thinking – a. Form – b. Content • Perceptions • Sensorium – a. Alertness – b. Orientation (person, place, time) – c. Concentration – d. Memory (immediate, recent, long term) – e. Calculations – f. Fund of knowledge – g. Abstract reasoning • Insight • Judgment Appearance • Examples of items in the appearance category include body type, posture, poise, clothes, grooming, hair, and nails. • Common terms used to describe appearance are healthy, sickly, ill at ease, looks older/younger than stated age, disheveled, childlike, and bizarre. • Signs of anxiety are noted: moist hands, perspiring forehead, tense posture and wide eyes. Appearance Example (from Psychosis video) • The pt. is a 23 y.o male who appears his age. There is poor grooming and personal hygiene evidenced by foul body odor and long unkempt hair. The pt. is wearing a worn T-Shirt with an odd symbol looking like a shield. This appears to be related to his delusions that he needs ‘antivirus’ protection from people who can access his mind.

Stange, M.A.,1 Evan M. Kleiman, Ph.D.,2 Louisa G. Sylvia, Ph.D.,3 Pedro Vieira da Silva Magalhaes,˜ M.D.,4 Michael Berk, M.D.,5,6 Andrew A. Nierenberg, M.D.,3 ∗ and Thilo Deckersbach, Ph.D.3 Background: Little is known about specific mood symptoms that may confer risk for suicidal ideation (SI) among patients with bipolar disorder (BD). We evaluated prospectively whether particular symptoms of depression and mania precede the onset or worsening of SI, among adults with or without a history of a suicide attempt. Methods: We examined prospective data from a large (N = 2,741) cohort of patients participating in the Systematic Treatment Enhance- ment Program for BD (STEP-BD). We evaluated history of suicide attempts at baseline, and symptoms of depression and mania at baseline and follow-up visits. Hierarchical linear modeling tested whether specific mood symptoms predicted subsequent levels of SI, and whether the strength of the associations differed based on suicide attempt history, after accounting for the influence of other mood symptoms and current SI. Results: Beyond overall current depression and mania symptom severity, baseline SI, and illness characteristics, several mood symptoms, including guilt, reduced self-esteem, psychomotor retardation and agitation, increases in appetite, and distractibility predicted more severe levels of subsequent SI. Problems with concentration, distraction, sleep loss and de- creased need for sleep predicted subsequent SI more strongly among individuals with a suicide attempt history.

Question #1 A 50-year-old woman who has been treated with sertraline for major depressive disorder for more than two years comes to the office because she has had weakness, cold intolerance, constipation, and weight gain during the past six months. Physical examination shows dry, coarse skin as well as bradycardia, hypothermia, andswelling of the hands and feet. Which of the following laboratory studies is the most appropriate to determine the diagnosis? (A) Liver function testing (B) Measurement of serum electrolyte levels (C) Measurement of serum estrogen level (D) Measurement of serum sertraline level (E) Measurement of serum thyroid-stimulating hormone level Content Area: Depressive Disorders (14%) Critique This question tests the examinee’s ability to determine the laboratory study that is most likely to specify the diagnosis. The correct answer is Option (E), measurement of serum thyroid- stimulating hormone level. Hypothyroidism is suspected on the basis of the patient’s symptoms of depression, weakness, constipation, and weight gain as well as the physical findings of bradycardia, hypothermia, swelling of the hands and feet, and dry, coarse skin. Measurement of serum thyroid-stimulating hormone level is the study that will either confirm or refute this suspected diagnosis. ©NCCPA. 2021. All rights reserved.

  • The ICD-10 Classification of Mental and Behavioural Disorders
    The ICD-10 Classification of Mental and Behavioural Disorders Clinical descriptions and diagnostic guidelines World Health Organization -1- Preface In the early 1960s, the Mental Health Programme of the World Health Organization (WHO) became actively engaged in a programme aiming to improve the diagnosis and classification of mental disorders. At that time, WHO convened a series of meetings to review knowledge, actively involving representatives of different disciplines, various schools of thought in psychiatry, and all parts of the world in the programme. It stimulated and conducted research on criteria for classification and for reliability of diagnosis, and produced and promulgated procedures for joint rating of videotaped interviews and other useful research methods. Numerous proposals to improve the classification of mental disorders resulted from the extensive consultation process, and these were used in drafting the Eighth Revision of the International Classification of Diseases (ICD-8). A glossary defining each category of mental disorder in ICD-8 was also developed. The programme activities also resulted in the establishment of a network of individuals and centres who continued to work on issues related to the improvement of psychiatric classification (1, 2). The 1970s saw further growth of interest in improving psychiatric classification worldwide. Expansion of international contacts, the undertaking of several international collaborative studies, and the availability of new treatments all contributed to this trend. Several national psychiatric bodies encouraged the development of specific criteria for classification in order to improve diagnostic reliability. In particular, the American Psychiatric Association developed and promulgated its Third Revision of the Diagnostic and Statistical Manual, which incorporated operational criteria into its classification system.
