BACKGROUND: X-linked ichthyosis is a dermatological condition caused by deficiency for the enzyme steroid sulfatase. Previously, X-linked ichthyosis/steroid sulfatase deficiency has been associated with developmental and neurological phenotypes. Here, we show for the first time, that X-linked ichthyosis may be comorbid with an additional psychiatric phenotype (psychosis). CASE PRESENTATION: We report the case of an 11-year-old Saudi Arabian boy with X-linked ichthyosis associated with psychosis, mental retardation, autism spectrum disorder, inattentive attention deficit hyperactivity disorder, and epilepsy...

Dopamine supersensitivity psychosis (DSP) is observed in patients with schizophrenia under antipsychotic treatment, and it is characterized by rebound psychosis, an uncontrollable psychotic episode following a stable state and tardive dyskinesia. DSP, first described in patients taking typical antipsychotics in the late 1970s, sometimes appears even in patients who are treated with current atypical antipsychotics. It was recently demonstrated that DSP can have a negative impact on the long-term prognosis of schizophrenia patients and that DSP could be involved in the etiology of some cases of treatment-resistant schizophrenia...

RATIONALE: Racemic (RS)-amisulpride (Solian(®)) is an atypical antipsychotic drug used to treat schizophrenia and dysthymia. Blockade of dopamine D2/D3 and/or serotonin 5-HT7 receptors is implicated in its pharmacological effects. While the (S)-amisulpride isomer possesses a robust discriminative cue, discriminative stimulus properties of (RS)-amisulpride have not been evaluated. OBJECTIVES: The present study established (RS)-amisulpride as a discriminative stimulus and assessed amisulpride-like effects of amisulpride stereoisomers, other benzamide derivatives, and antipsychotic, antidepressant, and anxiolytic drugs...

PURPOSE: Second-generation long-acting injectable therapies (SGA-LAIs) may reduce health care resource utilization (HRU) and health care costs compared with daily oral atypical antipsychotics (OAAs) in patients with schizophrenia due to reduced dosing frequency, delivery/monitoring by a health care provider, and improved adherence. The aim of the present study was to compare treatment patterns, HRU, and Medicaid spending in patients with schizophrenia initiated on SGA-LAIs (overall and according to agent) versus OAAs...

BACKGROUND: Catatonia is a commonly encountered syndrome, affecting 10-20% of various psychiatric populations and carrying significant medical co-morbidities. However, there are few established alternative treatment strategies when benzodiazepines are ineffective and electroconvulsive therapy is unavailable. OBJECTIVE: The authors systematically review evidence for alternative treatment strategies for catatonia using Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) guidelines...

OBJECTIVE: Clozapine is an atypical antipsychotic prescribed for treatment-resistant schizophrenic patients, but treatment with clozapine is strictly limited because it can induce lethal-hematologic side effects. We investigated the effects of short- and long-term exposure of human neutrophils derived from healthy subjects to clozapine and compared them with the effects of reactive metabolite of clozapine, olanzapine, and doxorubicin. METHODS: Neutrophils were exposed to clozapine and olanzapine (1, 10, 50, or 100 μM), reactive metabolite of clozapine (50 or 100 μM), or doxorubicin (0...

It is suggested that altered neuroplasticity contributes to the pathophysiology of schizophrenia and antipsychotics may exhibit some of their therapeutic efficacies by improving neurogenesis and/or proliferation of neural progenitors. The aim of this study is to investigate whether chronic antipsychotics treatment affect neurogenesis in adult mouse hippocampus. Animals were administered olanzapine, quetiapine, clozapine, risperidone, aripiprazole, or haloperidol via the osmotic minipump for 21 days and then injected with 5-bromo-2'-deoxyuridine (BrdU) to label mitotic cells...

Quetiapine is an atypical antipsychotic agent which is also prescribed for delirium due to its anti-dopaminergic effects; aphasia is an unusual side effect associated with the drug. Here, we report the case of an 83-year-old woman who was prescribed quetiapine (50 mg per day) for delirium. Unexpected, global aphasia occurred 3 days after treatment began. Complete recovery occurred following discontinuation of the drug. A brain computed tomography scan excluded intracranial hemorrhage and the laboratory results confirmed that no exacerbation of infection or electrolyte imbalances were present...

Schizophrenia treatment may see a paradigm shift due to development of new atypical antipsychotic drugs (APDs), with better tolerability due to more selective dopamine (DA) receptor blockade. Monitoring of these APD candidates in biological fluids is of great importance to reduce the development cost, to clarify the mechanism of action and ultimately to support the demonstration of efficacy of these molecules. Electrochemical approaches have attracted great attention for monitoring DA and APD levels but none of the methods developed so far aimed to screen APD candidates...

INTRODUCTION: Veterans with mental illness tend to have shorter life spans and suboptimal physical health because of a variety of factors. These factors include poor nutrition, being overweight, and smoking cigarettes. Nonphysical contributors that may affect quality of life are the stigma associated with mental illness, social difficulties, and spiritual crises. Current mental health treatment focuses primarily on the delivery of medication and evidence-based psychotherapies, which may not affect all the above areas of a Veteran's life as they focus primarily on improving psychological symptoms...

Atypical antipsychotics (AAPs) are considered to possess superior efficacy for treating both the positive and negative symptoms of schizophrenia; however, AAP use often causes excessive weight gain and metabolic abnormalities. Recently, several reports have demonstrated that AAPs activate sterol regulatory element-binding protein (SREBP). SREBP, SREBP cleavage-activating protein (SCAP) and insulin-induced gene (Insig) regulate downstream cholesterol and fatty acid biosynthesis. In this study, we explored the effects of clozapine, olanzapine and risperidone on SREBP signaling and downstream lipid biosynthesis genes in the early events of adipogenic differentiation in adipose-derived stem cells (ASCs)...

Children with autism are often medicated to manage emotional and behavioral symptoms; yet, data on such pharmacotherapy is insufficient. In this study, we investigated the Korean National Health Insurance Claims Database (NHICD) information related to autism incidence and psychotropic medication use. From the 2010-2012 NHICD, we selected a total of 31,919,732 subjects under 19 years old. To examine the diagnostic incidence, we selected patients who had at least one medical claim containing an 10th revision of International Statistical Classification of Diseases and Related Health Problems (ICD-10) code for pervasive developmental disorder, F84, not diagnosed in the previous 360 days...

BACKGROUND: Atypical antipsychotics, like risperidone purportedly, score over their typical counterparts in terms of their lower propensity toward producing extrapyramidal symptoms (EPS). However, recent studies have furnished evidence to the contrary. Hereby, we present a case series implicating risperidone as the causative agent for EPS. METHODS: As a part of the pharmacovigilance programme of India, the authors have assessed 10 physician-reported cases of EPS among the 1,830 patients who were prescribed risperidone within the time period of January 2012-December 2014 in a tertiary care hospital in South India...

Olanzapine is an atypical antipsychotic indicated for the treatment of schizophrenia and known to be effective in the management of delirium. In addition to its use for these indications olanzapine has also been used in the management of chemotherapy induced nausea and vomiting and otherwise difficult to control nausea and vomiting in palliative care settings. Although considered to be well tolerated with a lower incidence of extrapyramidal effects than first generation antipsychotics there are a small number of reports of olanzapine inducing delirium...

Atypical antipsychotic medications, such as risperidone, aripiprazole, and olanzapine, have utility in treating motor tics, particularly in Tourette syndrome. In rare cases, atypical antipsychotic medications have been associated with adult-onset motor tics. Such adverse drug reactions have been documented in response to quetiapine, aripiprazole, and amisulpride. Here, we report, to our knowledge, the first case of adult-onset motor tics related to olanzapine administration.
