The Clinical Presentation of Mood Disorders. Bob Boland MD Slide 1 The Clinical Presentation of Mood Disorders. Bob Boland MD Slide 1 The Clinical Presentation of Mood Disorders Slide 2 For the mood disorders, we’re going to have to Concentrating On cover both depression AND mania. • Depression – Major Depression •Mania – Bipolar Disorder (Manic-Depression) Slide 3 Phenomenology: Once again, we’ll use the mental status exam to The Mental Status Exam consider the phenomenology of the mood • General Appearance disorders. • Emotional • Thought • Cognition • Judgment and Insight • Reliability Clinical Presentation of Mood Disorders Slide 4 In both cases, people may look “normal” with General Appearance mood disorders. However, as the disorder • Depression worsens, often appearance is affected. Though •Mania one can imagine a variety of appearances, typically we see depressed patients taking less care of their appearance, whereas manic patients may be more flamboyant. Slide 5 I prefer the word “dysphoric” (i.e., “feeling Emotions: Depression bad”) to “depressed” in describing the typical •Mood sad mood of the depressed patient. However – Dysphoric – Irritable, angry patients may not be simply sad. They may be – Apathetic more irritable, angry, or feel like they have no •Affect – Blunted, sad, constricted emotion at all. Their affect may be sad, but it could also be blunted, or show less emotion altogether. Slide 6 The typical manic mood is euphoria. However, Emotions: Mania again, patients may instead be irritable. •Mood Typically, manic patients are animated with –Euphoric – Irritable exaggerated emotional styles. •Affect – Heightened, dramatic, labile Page 2 of 14 Clinical Presentation of Mood Disorders Slide 7 Depressed people often describe problems with Thought: Depression their thoughts—thinking more slowly, having • Process trouble organizing their thoughts.

Later follow ups suggest it may –5-7% –2:1 ♀:♂ be even more common than that. It is more – $53 billion/year in US – World: most costly common in woman than men—this seems to be (developed) true worldwide, and most believe this reflects some biological predisposition, though social causes remain possible and plausible. It is one of the most costly diseases known to man, and certainly the most costly in developed countries. This is due to the fact that it often strikes persons during the most productive years of their lives. Though many famous people have suffered from it, this probably has more to do with the fact that this disorder is common, rather than any particular association with creativity. Page 4 of 14 Clinical Presentation of Mood Disorders Slide Bipolar disorder is somewhat less common. 12 Epidemiology The gender difference is closer to parity. •Bipolar Disorders Though many very productive and creative –1% – ~1:1 ♀:♂ people have had the disorder, they usually have not been productive during highs and lows of the disorder. Slide In diagnosing the mood disorders, one should 13 Diagnosis and Criteria be aware that DSM describes first episodes, • Episodes Versus Disorders which are syndromes, or collections of symptoms, which then become the building blocks for the actual disorders.

  • Neuroradiology of Non-Alzheimer's Disease Dementias
    Hong Kong J Radiol. 2015;18:58-73 | DOI: 10.12809/hkjr1414267 PICTORIAL ESSAY Neuroradiology of Non-Alzheimer’s Disease Dementias YL Dai1, K Wang1, TCY Cheung1, DLK Dai2 1Department of Imaging and Interventional Radiology, Prince of Wales Hospital, The Chinese University of Hong Kong; 2Department of Medicine and Therapeutics, Prince of Wales Hospital, Hospital Authority, Hong Kong ABSTRACT Dementia is an increasingly prevalent disease of the ageing population. Although Alzheimer’s disease is still the most common cause of dementia, there is emerging clinical interest in other, less common, causes of dementia that can affect patients at a younger age. Early diagnosis of these non-Alzheimer’s disease dementias is now possible with the aid of neuroimaging, including computed tomography and magnetic resonance imaging, as well as newer modalities such as magnetic resonance spectroscopy, diffusion tensor imaging, and single-photon emission computed tomography. The imaging features of some of the more common non- Alzheimer’s disease dementias will be discussed in this review in order to help clinicians and radiologists better diagnose these conditions.

  • Is Your Depressed Patient Bipolar?
    J Am Board Fam Pract: first published as 10.3122/jabfm.18.4.271 on 29 June 2005. Downloaded from EVIDENCE-BASED CLINICAL MEDICINE Is Your Depressed Patient Bipolar? Neil S. Kaye, MD, DFAPA Accurate diagnosis of mood disorders is critical for treatment to be effective. Distinguishing between major depression and bipolar disorders, especially the depressed phase of a bipolar disorder, is essen- tial, because they differ substantially in their genetics, clinical course, outcomes, prognosis, and treat- ment. In current practice, bipolar disorders, especially bipolar II disorder, are underdiagnosed. Misdi- agnosing bipolar disorders deprives patients of timely and potentially lifesaving treatment, particularly considering the development of newer and possibly more effective medications for both depressive fea- tures and the maintenance treatment (prevention of recurrence/relapse). This article focuses specifi- cally on how to recognize the identifying features suggestive of a bipolar disorder in patients who present with depressive symptoms or who have previously been diagnosed with major depression or dysthymia. This task is not especially time-consuming, and the interested primary care or family physi- cian can easily perform this assessment. Tools to assist the physician in daily practice with the evalua- tion and recognition of bipolar disorders and bipolar depression are presented and discussed. (J Am Board Fam Pract 2005;18:271–81.) Studies have demonstrated that a large proportion orders than in major depression, and the psychiat- of patients in primary care settings have both med- ric treatments of the 2 disorders are distinctly dif- ical and psychiatric diagnoses and require dual ferent.3–5 Whereas antidepressants are the treatment.1 It is thus the responsibility of the pri- treatment of choice for major depression, current mary care physician, in many instances, to correctly guidelines recommend that antidepressants not be diagnose mental illnesses and to treat or make ap- used in the absence of mood stabilizers in patients propriate referrals.

  • Types of Bipolar Disorder Toms Are Evident
    MOOD DISORDERS ASSOCIATION OF BRITISH COLUmbIA T Y P E S O F b i p o l a r d i s o r d e r Bipolar disorder is a class of mood disorders that is marked by dramatic changes in mood, energy and behaviour. The key characteristic is that people with bipolar disorder alternate be- tween episodes of mania (extreme elevated mood) and depression (extreme sadness). These episodes can last from hours to months. The mood distur- bances are severe enough to cause marked impairment in the person’s func- tioning. The experience of mania is not pleasant and can be very frightening to The Diagnotistic Statisti- the person.

People with bipolar disorder vary in how often they experience an episode of either mania or depression. Mood changes with bipolar disorder typically occur gradually. For some individuals there may be periods of wellness between the different mood episodes. Some people may also experience multiple episodes within a 12 month period, a week, or even a single day (referred to as “rapid cycling”). The severity of the mood can also range from mild to severe. Establishing the particular type of bipolar disorder can greatly aid in determin- ing the best type of treatment to manage the symptoms.

Sederlund, Lawrence R. Burns * and William Rogers Psychology Department, Grand Valley State University, Allendale, MI 49417, USA; [email protected] (A.P.S.); [email protected] (W.R.) * Correspondence: [email protected]; Tel.: +001-616-331-2862 Received: 16 May 2020; Accepted: 13 July 2020; Published: 15 July 2020 Abstract: Background: Perfectionism is currently conceptualized using a multidimensional model, with extensive research establishing the presence of both maladaptive and adaptive forms. 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

  • Caring for Transgender People with Severe Mental Illness
    Caring for Transgender People with Severe Mental Illness MAY 2018 Transgender people, like the general population, can suffer from a variety of common and rare severe mental health illnesses (SMI). Severe mental illness (SMI) refers to psychiatric disorders that are relatively persistent and result in comparatively severe impairment in major areas of function, disruption of normal developmental processes, and reduced vocational capacity and social relationships.1 People with SMI experience unique vulner- abilities within society, which include a longstanding history of being institu- tionalized, marginalized, victimized, and subjected to experimental psychiatric interventions.2 There is strong evidence that people with SMI are woefully underserved and rarely receive evidence-based treatments even when they are able to access care.2 In turn, transgender people are more likely than the general population to expe- rience discrimination in housing, employment, and healthcare.3 Many are verbal- ly and physically victimized starting at a young age.3 Abuse related to gender minority status has a dose-response relationship with major depressive disorder and suicidality among transgender adolescents.4 Daily experiences of anti-trans- gender stigma, prejudice, and discrimination become internalized and ultimately affect psychological health.5,6 An estimated 40% of all transgender people have attempted suicide in their lifetimes.3 Though research on transgender behavioral health is limited, studies have found a higher risk for mood disorders, posttrau- matic stress disorder (PTSD), and substance use disorders, but not psychotic disorders compared to the rest of the population.7,8 When risk profiles based on transgender status and SMI intersect, patients are liable to experience a particu- larly dangerous array of vulnerabilities that require attentive, specialized care.
