Synthetic cathinones inhibit monoamine transporters, such as serotonin, norepinephrine, and dopamine transporters, and act on the central nervous system via increasing synaptic concentrations of monoamines. These compounds, which are highly addictive and potentially poisonous, are new psychoactive substances. In this study, we investigated the toxicokinetics of the synthetic cathinone, α-pyrrolidinohexanophenone (α-PHP), and assessed the relationship between the toxicokinetics and the long-term clinical symptoms induced by α-PHP in a male patient...

Schizophrenia is a major psychiatric disorder that has a massive, long-lasting negative impact on the patients as well as society. While positive symptoms (i.e., delusions and hallucinations), negative symptoms (i.e., anhedonia, social withdrawal), and cognitive impairments are traditionally considered the most prominent features of this disorder, the role of sleep and sleep disturbances has gained increasing prominence in clinical practice. Indeed, the vast majority of patients with schizophrenia report sleep abnormalities, which tend to precede illness onset and can predict an acute exacerbation of psychotic symptoms...

Although both anxiety and cognitive biases contribute to psychosis, it is still unclear whether these factors interact in their influence on psychotic symptoms. The aim of the study was to examine the interactions between trait anxiety, cognitive biases and delusion-like experiences (PLEs) in a non-clinical sample; the moderational role of attentional control on this relationship was also considered in the study. Two subgroups of participants, 92 individuals (M=24.76; SD=6.33) with heightened (HA) trait anxiety and 78 individuals (M=23...

INTRODUCTION: Cognitive and/or memory impairment are the main clinical markers currently used to identify subjects at risk of developing dementia. This study aimed to explore the relationship between the presence of neuropsychiatric symptoms and dementia incidence. METHODS: We analyzed the association between neuropsychiatric symptoms and incident dementia in a cohort of 1355 Mexican older adults from the general population over 3 years of follow-up, modeling cumulative incidence ratios using Poisson models...

INTRODUCTION: Neuropsychiatric symptoms (NPS) are common at all stages of Alzheimer disease (AD). Delusions in AD are associated with negative clinical consequences and may signal rapid disease progression. Hence, we sought to determine the prevalence of delusions in drug-naïve (no cholinesterase inhibitor or neuroleptic medications) AD patients. METHODS: In this meta-analysis, a search of the EMBASE, MEDLINE, and PsycINFO databases was performed. We selected studies reporting delusion prevalence measured by the Neuropsychiatric Inventory (NPI) in drug-naïve AD patients...

We aimed to assess suicidality risk amongst people who had had anti-N-methyl-D-aspartate receptor (NMDAR) encephalitis. All people with a definitive diagnosis of anti-NMDAR encephalitis in West China Hospital between June 2012 and February 2017 were identified and their notes were retrospectively reviewed. Demographic and clinical characteristics and risk predictors for suicidality were summarized; those with suicidality were compared to those without. 17 of 133 people (13%) presented with suicidality symptoms: 7 (5%) with suicidal ideation; 8 (6%) who attempted suicide; and 2 (1...

This is the first case report in a country predominated by Chinese that describes the physical abuse of a recipient by the inducer in shared delusional disorder. The report describes a 42-year-old patient who physically abused her father until he submitted to her delusions. Subsequently and for years, both sustained persecutory delusions against their neighbours. While the patient was undergoing treatment, the father continued reinforcing her delusions. There is a need to explore the possibility of any forms of abuse of the recipient by the inducer in shared psychotic disorder...

Psychosis symptoms (delusions and hallucinations) are multifactorial in origin and, in later life, occur in the context of schizophrenia, delirium, dementia, delusional and schizophrenia-like disorders, mood disorders, and alcohol or substance abuse. The current article provides a clinical overview of very late-onset (after age 60) schizophrenia-like psychosis (VLOSLP), summarizing the literature on treatment options and reflecting on the role of psychiatric-mental health nurses (PMHNs). Increased awareness of the clinical presentation, key features, and evidence-based treatment options will assist PMHNs to confidently recognize this often under-diagnosed disorder and adopt a more assertive role in terms of engagement and follow up...

The study tested the predicted differences in phenomenology (self-esteem and depression) and insecurity of the subgroups of paranoia proposed by the Trower and Chadwick (1995) model of paranoia. Thirty-two inpatients experiencing persecutory delusions were assigned to either the poor me or bad me paranoid group. Questionnaire assessment of depression and self-esteem were conducted. A Dot Probe task measured detection latency (reaction time) to poor me words, bad me words and neutral words. The poor me and bad me groups displayed the predicted phenomenological differences...

The authors present the case of a 24-year-old male with treatment-resistant schizophrenia, with predominant severe delusion and hallucination, who received bone marrow transplantation (BMT) for acute myeloid leukemia. After BMT, he showed a remarkable reduction in psychotic symptoms without administration of neuroleptics. He also showed drastic improvement in social functioning. Follow-up evaluations 2 and 4 years after BMT showed persistent significant improvement of the psychotic state and social functioning...

Garcinia cambogia is a Southeast Asian fruit becoming increasingly popular as a weight management supplement. Hydroxycitric acid (HCA) is the primary active ingredient which demonstrates serotonergic- and muscarinic-enhancing properties via inhibition of selective serotonin reuptake and acetylcholinesterase. We report a young adult female with no history of bipolar disorder who developed mania and psychosis approximately 1 week following initiation of G cambogia and the Cleanse and Detox™ dietary supplement manufactured by Apex Vitality Health...

REVIEW
Lucie Berkovitch, Stanislas Dehaene, Raphaël Gaillard
Schizophrenia is a severe and complex psychiatric disorder resulting in delusions, hallucinations, and cognitive impairments. Across a variety of paradigms, an elevated threshold for conscious perception has been repeatedly observed in persons with schizophrenia. Remarkably, even subtle measures of subliminal processing appear to be preserved. We argue here that the dissociation between impaired conscious access and intact unconscious processing may be due to a specific disruption of top-down attentional amplification...

Schizophrenia is a pervasive neuropsychiatric disorder affecting over 1% of the world's population. Dopamine system dysfunction is strongly implicated in the etiology of schizophrenia. Data support the long-standing concept of schizophrenia as a disease characterized by hyperactivity within midbrain (striatal D2) dopamine systems. In addition, there is now considerable evidence that glutamate neurotransmission, mediated through NMDA-type receptors, is deficient in patients with schizophrenia and that hypoactivity in cortical dopamine and glutamate pathways is a key feature of this serious mental disorder...

OBJECTIVE: To examine the nature of the association between affective disorders and psychosis in Parkinson's disease (PD). BACKGROUND: In PD, psychosis and affective disorders are common and independently impact quality of life and mortality. Both depression and psychosis are correlated with the occurrence of cognitive dysfunction, suggesting that they may share neurobiological substrates. Anxiety has not been examined as a correlate of psychosis. METHODS: 144 PD subjects were evaluated with the Schedule for Assessment of Positive Symptoms to assess psychotic features, while depression and anxiety were examined by the Structured Clinical Interview for DSM-IV-TR (SCID) and self-assessment scales Beck Depression Inventory II (BDI-II) and Beck Anxiety Inventory (BAI)...

Krystyna Bielecka, Mira Marcinów
In this paper, we defend a representational approach to at least some kinds of non-human psychopathology. Mentally-ill non-human minds, in particular in delusions, obsessive-compulsive disorders and similar cognitive states, are traditionally understood in purely behavioral terms. In contrast, we argue that non-human mental psychopathology should be at least sometimes not only ascribed contentful mental representation but also understood as really having these states. To defend this view, we appeal to the interactivist account of mental representation, which is a kind of a constructive approach to meaning...

Dextromethorphan (3-methoxy-N-methylmorphinan), also known as "DXM" and "the poor man's PCP," is a synthetically produced drug that is available in more than 140 over-the-counter cough and cold preparations. Dextromethorphan (DXM) has overtaken codeine as the most widely used cough suppressant due to its availability, efficacy, and safety profile at directed doses. However, DXM is subject to abuse. When consumed at inappropriately high doses (over 1500 mg/day), DXM can induce a state of psychosis characterized by Phencyclidine (PCP)-like psychological symptoms, including delusions, hallucinations, and paranoia...

Antibacterial drugs are the most consumed group of drugs in the modern hospitals. Standard methods of antibiotic sensitivity are labour and time-consuming, taking up to 24 hours after the pure culture is isolated (the analysis typically lasts up to 72 hours). Working out express diagnostic methods is of importance, and studies are made in various directions. Flow cytometry in detecting resistant E. coli strains was used. Flow cytometry fluorescent dyes were used to stain viable and dead cells. For method validation, relative accuracy, relative susceptibility, relative specificity and Cohen's kappa test were determined compared to the delusion test...
