BACKGROUND: Quetiapine is an atypical antipsychotic prescribed for schizophrenia, bipolar disorder, multiple drug abuse (MDA), generalized anxiety disorder, severe depression, dementia, and mood disorders. Prescription of quetiapine varies according to use, with side effects increasingly reported with higher doses. Many previous case reports highlighted the misuse of the drug. Here we studied the prescribing patterns of quetiapine in multiple drug abuse (MDA), depression, and psychosis patients in the Madinah region in Saudi Arabia...

AIMS: Quetiapine is widely used to treat psychiatric disorders such as major depression, generalized anxiety disorder, dysthymic disorder, and insomnia other than schizophrenia and bipolar disorder. This study investigated the diagnostic distribution of quetiapine use in patients in a psychiatric hospital, the doses of quetiapine prescribed, and the plasma concentrations (Cps) of quetiapine and active metabolites. METHODS: We enrolled 107 patients who had been prescribed quetiapine for at least 4 weeks...

Background: Comorbid somatic diseases increase the death risk and affect the condition, treatment, and prognosis of older psychiatric patients. We investigated the comorbidity and drug treatment in older patients with psychosis. Methods: This retrospective study used data from 3,115 older psychiatric in-patients hospitalized at the Shanghai Mental Health Center Affiliated to Shanghai Jiaotong University School of Medicine, China discharged from 2005 to 2015. Descriptive analyses of patients' age, sex, treatment drugs, diagnoses (based on ICD-10), and time trend were performed...

Categorial systems of nosology are based on a cross-sectional enumeration of symptoms with a predefined cut-off, but hardly capture rapid fluctuations of manifestation nor longitudinal characteristics, e.g., cyclicity. Especially with disorders presenting with an admixture or frequent change of psychotic and affective symptoms, diagnostic specifity of the DSM and ICD diminishes. In those instances, alternative concepts as cycloid psychosis might display more accurately the very characteristics and course of a mental disorder and help to tailor individualized treatments...

Objectives: To compare demographic, clinical, and familial characteristics across bipolar disorder (BD) subtypes in adolescents. Methods: A total of 168 participants, 13 to 19 years of age, with BD-I ( n  = 41), BD-II ( n  = 68), or operationalized BD-not otherwise specified (NOS) ( n  = 59) were recruited from a tertiary subspecialty clinic at an academic health sciences center. Diagnoses were determined using the semistructured K-SADS-PL (Schedule for Affective Disorders and Schizophrenia for School-Age Children-Present and Lifetime Version) interview...

In the central nervous system omega-3 fatty acids modulate cell signaling and affect dopaminergic and serotonergic pathways. On this basis, a new application for omega-3 fatty acids has been proposed, concerning the treatment of several psychiatric disorders. The present article is an update of a previous systematic review and is aimed to provide a complete report of data published in the period between 1980 and 2019 on efficacy and tolerability of omega-3 fatty acids in psychiatric disorders. In July 2019, an electronic search on PUBMED, Medline and PsychINFO of all RCTs, systematic reviews and meta-analyses on omega-3 fatty acids and psychiatric disorders without any filter or MESH restriction was performed...

Omega-3 treatment studies for multi-episode schizophrenia or clinical high risk for conversion to psychosis states have had variable, and often negative, results. To examine adjunctive omega-3 treatment for recent onset psychosis, participants aged 15-40 years with recent onset schizophrenia-spectrum (n = 46) or bipolar (n = 4) disorders and current psychotic symptoms were treated for 16 weeks with risperidone and randomly-assigned omega-3 (EPA 740 mg and DHA 400 mg daily) or matching placebo...

GABAergic drugs are of interest for the treatment of anxiety, depression, bipolar disorder, pain, cognitive impairment associated with schizophrenia (CIAS), and other neuropsychiatric disorders. Some evidence suggests that TPA-023, (7-(1,1-dimethylethyl)-6-(2-ethyl-2H-1,2,4-triazol-3-ylmethoxy)-3-(2-fluorophenyl)-1,2,4-triazolo[4,3-b] pyridazine), a GABAA α2,3 subtype-selective GABAA partial agonist and α1/5 antagonist, and the neurosteroid, pregnenolone sulfate, a GABAA antagonist, may improve CIAS in pilot clinical trials...

BACKGROUND: Antipsychotic drug use among children and adolescents is increasing, and there is growing concern about off-label use and adverse effects. The present study aims to investigate the incidence, psychiatric co-morbidity and pharmacological treatment of severe mental disorder in Norwegian children and adolescents. METHODS: We obtained data on mental disorders from the Norwegian Patient Registry on 0-18 year olds who during 2009-2011 were diagnosed for the first time with schizophrenia-like disorder (International Classification of Diseases, 10th revision codes F20-F29), bipolar disorder (F30-F31), or severe depressive episode with psychotic symptoms (F32...

Alzheimer's Disease (AD) is an age-related neurodegenerative disorder characterized by progressive cognitive impairments and chronic inflammation that affects over 30 million people all over the world. Most of the Alzheimer's patients also suffer from psychosis, aggression, agitation, depression, anxiety, and many other behavioral and psychological symptoms of dementia. Unfortunately, the currently available anti-AD drugs provide modest symptomatic relief, and they do not reverse the neurodegeneration. Therefore, the average life expectancy after diagnosis is between six and ten years...

OBJECTIVE: To examine the recorded indication for antipsychotic prescriptions in UK primary care. DESIGN: Cohort study. SETTING: Primary care. PARTICIPANTS: Individuals prescribed antipsychotics between 2007 and 2011. MEASURES: The proportion of individuals prescribed antipsychotics with a diagnosis of (1) psychosis and bipolar disorder, (2) other diagnoses including depression, anxiety and dementia and (3) none of these diagnoses...

INTRODUCTION: Dysfunctional serotonin signaling has been linked to the pathogenesis of autism, obsessive compulsive disorder, mood disorders and schizophrenia. While the hypo-activity of serotonin signaling is involved in the pathogenesis of depression, anxiety and obsessive compulsive disorder; LSD, an agonist of serotonin type 2 receptor (5-HTR2A) induces psychosis. Therefore, anxiety and depressive disorders are treated by SSRIs which inhibit serotonin transporter (5-HTT) while psychotic disorders are controlled by drugs that block serotonin and/or dopamine receptors...

OBJECTIVE: This study aimed to determine the prevalence of prescribing antipsychotics to adults without schizophrenia or bipolar disorder and to identify factors associated with such off-label use. METHODS: Patients with at least one prescription for an antipsychotic medication from the Department of Veterans Affairs (VA) during fiscal year (FY) 2007 were identified in national VA administrative databases. Rates of off-label antipsychotic use were determined along with average doses...

A 44 base pair insertion ("l")/deletion ("s") polymorphism (called 5-HTTLPR) in the 5' promoter region of the human serotonin transporter gene (SLC6A4) modulates expression and has been associated to anxiety and depressive traits in otherwise healthy individuals. In individuals with psychiatric diagnoses, including schizophrenia, it seems to modulate symptom severity. Thus, it may be a disease modifying gene. In this study, 92 patients with psychosis (including schizophrenia, schizoaffective disorder, bipolar psychosis, and major depression) were assessed at their first hospital admission...

Emil Kraepelin proposed to separate psychiatric disorders with psychotic features into two major categories, dementia praecox (later schizophrenia) and manic-depressive insanity (later bipolar disorder and major depression). Over the past century, there have been many efforts to categorize conditions that do not fit readily in either group. These conditions include many cases of acute psychotic illnesses of limited duration, with recovery between recurrences. For some of these conditions, Karl Kleist proposed the term cycloid psychosis: acute features were psychotic, as in schizophrenia, but the course was episodic, as in manic-depression...

OBJECTIVE: The aim of this double-blind, placebo-controlled study was to evaluate the efficacy and tolerability of ziprasidone in the treatment of adult patients with borderline personality disorder. METHOD: Sixty DSM-IV borderline personality disorder patients were included from March 2004 to April 2006 in a 12-week, single-center, double-blind, placebo-controlled study. The subjects were randomly assigned to ziprasidone or placebo in a 1:1 ratio following a 2-week baseline period...

Antipsychotic medications have made a significant contribution to the care of the mentally ill people over the past 50 years, with good evidence that both typical and atypical agents are effective in the treatment of schizophrenia and related conditions. In addition they are widely used to good effect in other disorders including psychotic depression, dementia and delirium. Both typical and atypical agents may cause severe side-effects and, in the elderly in particular, there is an increased propensity for drug interactions...

The prevalence of psychiatric disorders in primary care is approximately 22%. These disorders include major depressive disorder, panic disorder, alcohol dependence/abuse, generalized anxiety disorder, and obsessive-compulsive disorder. The deinstitutionalization movement has placed an increasing number of severe and persistently mentally ill persons, defined as those with schizophrenia, psychosis, bipolar, and unipolar disorders, into the community. Nurses working in acute primary care, home health, and long-term medical settings can expect to encounter patients who are using prescriptive psychotropic medications; these patients may be experiencing adverse reactions...
