  • Two Cases of Intractable Auditory Hallucination Successfully Treated with Sound Therapy

Two cases of intractable auditory hallucination successfully treated with sound therapy Yutaka Kaneko, M.D. 1 Yasuhiko Oda, M.D. 2 Fumiyuki Goto, M.D. 3 Abstract We report two cases of patients with schizoaffective disorder with treatment-refractory auditory verbal hallucinations (AVHs) who were successfully treated with sound therapy, which is effective to treat tinnitus. AVHs in both patients were alleviated within about one month, and no recurrence was reported for 31 and 17 months after the sound the- rapy together with medication. Further studies may confirm the therapeutic value of sound therapy in patients with intractable AVHs.

  • Anhedonia of Patients with Schizophrenia and Schizoaffective
    Original Contributions Anhedonia of Patients with Schizophrenia and Schizoaffective Disorder is Attributed to Personality-Related Factors Rather than to State-Dependent Clinical Symptoms Michael S. Ritsner 1 Abstract Purpose: The aim of the current study was to to explore the concurrent attribution of illness- and personality-related variables to the levels of physical and social anhedonia in patients with schizophrenia (SZ) and schizoaffective disor- der (SA). Method: Eighty-seven stable patients with SZ/SA were assessed using the revised Physical Anhedonia Scale (PAS) and the Social Anhedonia Scale (SAS) illness- and personality-related variables. Correlation and regression analyses were performed. Results: Three subgroups of patients were stratified by level of hedonic functioning: 52.9% passed the PAS and SAS cut-off (“double anhedonics”), 14.9% the PAS cut-off and 18.4% the SAS cut-off (“hypohe- donics”), and 13.8% did not reach the PAS or SAS cut-off (“normal hedonics”). Increased negative and emotional distress symptoms together with low levels of task-oriented and avoidance-coping styles, self-efficacy, and social sup- port were significantly correlated with PAS/SAS scores. Multivariate regression analysis indicated that the contribu- tion of illness-related predictors was 4.1% to the variance of PAS and 5.5% to SAS scores, whereas the contribution of personality-related predictors was 24.1% for PAS and 14.1% for SAS scores. The predictive value of negative symptoms did not reach significant levels.Conclusions: The hedonic functioning of SZ/SA patients is attributed to a number of personality-related factors rather than to state-dependent clinical symptoms.

  • 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.)

    Molecular Psychiatry (2014) 19, 209–213 & 2014 Macmillan Publishers Limited All rights reserved 1359-4184/14 www.nature.com/mp ORIGINAL ARTICLE Specificity of psychosis, mania and major depression in a contemporary family study CL Vandeleur1, KR Merikangas2, M-PF Strippoli1, E Castelao1 and M Preisig1 There has been increasing attention to the subgroups of mood disorders and their boundaries with other mental disorders, particularly psychoses. The goals of the present paper were (1) to assess the familial aggregation and co-aggregation patterns of the full spectrum of mood disorders (that is, bipolar, schizoaffective (SAF), major depression) based on contemporary diagnostic criteria; and (2) to evaluate the familial specificity of the major subgroups of mood disorders, including psychotic, manic and major depressive episodes (MDEs). The sample included 293 patients with a lifetime diagnosis of SAF disorder, bipolar disorder and major depressive disorder (MDD), 110 orthopedic controls, and 1734 adult first-degree relatives. The diagnostic assignment was based on all available information, including direct diagnostic interviews, family history reports and medical records. Our findings revealed specificity of the familial aggregation of psychosis (odds ratio (OR) ¼ 2.9, confidence interval (CI): 1.1–7.7), mania (OR ¼ 6.4, CI: 2.2–18.7) and MDEs (OR ¼ 2.0, CI: 1.5–2.7) but not hypomania (OR ¼ 1.3, CI: 0.5–3.6). There was no evidence for cross-transmission of mania and MDEs (OR ¼ .7, CI:.5–1.1), psychosis and mania (OR ¼ 1.0, CI:.4–2.7) or psychosis and MDEs (OR ¼ 1.0, CI:.7–1.4).

Past studies have emphasized controlling negative affect, but there is an emerging trend in the depression literature to focus on positive emotion. The current study employed several psychophysiological tools, postauricular reflex, startle blink reflex, and event- related potential (ERP) components such as P3 and the late positive potential (LPP), to assess the dissociable components in positive emotion (consummatory and anticipatory processes).

  • Excited Delirium” and Appropriate Medical Management in Out-Of-Hospital Contexts
    APA Official Actions Position Statement on Concerns About Use of the Term “Excited Delirium” and Appropriate Medical Management in Out-of-Hospital Contexts Approved by the Board of Trustees, December 2020 Approved by the Assembly, November 2020 “Policy documents are approved by the APA Assembly and Board of Trustees. These are . position statements that define APA official policy on specific subjects. .” – APA Operations Manual Issue: As noted in the APA’s Position Statement on Police Interactions with Persons with Mental Illness (2017), in a range of crisis situations, law enforcement officers are called as first responders and may find individuals who are agitated, disorganized and/or behaving erratically. Such behaviors may be due to mental illness, intellectual or developmental disabilities, neurocognitive disorders, substance use, or extreme emotional states. Police responses to calls for behavioral health crises have been known to result in tragic outcomes, including injury or death. The concept of “excited delirium” (also referred to as “excited delirium syndrome (ExDs)”) has been invoked in a number of cases to explain or justify injury or death to individuals in police custody, and the term excited delirium is disproportionately applied to Black men in police custody. Although the American College of Emergency Physicians has explicitly recognized excited delirium as a medical condition, the criteria are unclear and to date there have been no rigorous studies validating excited delirium as a medical diagnosis. APA has not recognized excited delirium as a mental disorder, and it is not included in the Diagnostic and Statistical Manual of Mental Disorders (DSM- 5). The DSM-5 recognizes Delirium, hyperactive type, but the symptoms of this condition differ in many ways from the symptoms typically attributed to excited delirium (e.g., superhuman strength, impervious to pain, etc.).
