Hallucinations have been described in various clinical populations, but they are neither disorder nor disease specific. In schizophrenia patients, hallucinations are hallmark symptoms and auditory ones are described as the more frequent. In Parkinson's disease, the descriptions of hallucination modalities are sparse, but the hallucinations do tend to have less negative consequences. Our study aims to explore the phenomenology of hallucinations in both hallucinating schizophrenia patients and Parkinson's disease patients using the Psycho-Sensory hAllucinations Scale (PSAS)...

In psychiatric classifications, hallucinations (mainly auditory hallucinations) are one of the fundamental criteria for establishing a schizophrenia diagnosis or any of the related psychotic disorder's diagnoses. The conceptual proximity between delusions and hallucinations was maintained until the end of the XIX century, with several supporters during the XX century. Their limits were not yet definitely defined in terms of Descriptive Psychopathology, and much less so in terms of biochemical and anatomical models...

Hallucinations constitute one of the 5 symptom domains of psychotic disorders in DSM-5, suggesting diagnostic significance for that group of disorders. Although specific featural properties of hallucinations (negative voices, talking in the third person, and location in external space) are no longer highlighted in DSM, there is likely a residual assumption that hallucinations in schizophrenia can be identified based on these candidate features. We investigated whether certain featural properties of hallucinations are specifically indicative of schizophrenia by conducting a systematic review of studies showing direct comparisons of the featural and clinical characteristics of (auditory and visual) hallucinations among 2 or more population groups (one of which included schizophrenia)...

Schizophrenia is a debilitating illness, present in approximately 1% of the global population. It is manifested through positive symptoms including delusions, hallucinations, disorganized thoughts and negative symptoms such as avolition, alogia, and apathy. In 2013 the 5th edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) has been released and some changes were introduced to make diagnosis of schizophrenia more accurate and precise, but researchers are already studying how to improve again the diagnostic criteria of this disorder...

Patients with schizophrenia suffer from symptoms such as hallucination and delusion. There are currently a number of publications that discuss the treatment, diagnosis, prognosis, and damage in schizophrenia. This study utilized joint independent component analysis to process the images of GMV and WMV and incorporated the Wisconsin card sorting test (WCST) and the positive and negative syndrome scale (PANSS) to examine the correlation of obtained brain characteristics. We also used PANSS score to classify schizophrenic patients into acute and subacute cases, to analyze the brain structure differences...

: Lead was one of the most dangerous environmental toxic substances for a long time in western countries, and this is still the case for many places on earth today. Its neurotoxic potential is highly significant but its secure blood level concentration remains unknown. The aim of this study was to approach the above issue from the perspective of social psychiatry. A systematic search was made of Dialog and Datastar interfaces for data regarding the neuropsychiatric complications of direct or chronic exposure to lead, and a review of the relevant literature was conducted using the databases Medline, Embase, CAB Global Health and Cochrane...

To advance the area of phenomenology of voices and their interrelatedness to forms of delusions this study investigated the prevalence and interrelatedness of co-occurring auditory verbal hallucinations (AVHs) and delusions. Additionally we explored the characterization of distinct sub-categories/clusters of AVHs and delusions. Ninety-two participants experiencing psychosis were administered standardized clinical measures. We found a significant diagnostic difference with increased prevalence of co-occurring AVHs and delusions within the schizophrenia group compared to the bipolar with psychosis group...

BACKGROUND: Voice hearing experiences, or auditory verbal hallucinations, occur in healthy individuals as well as in individuals who need clinical care, but news media depict voice hearing primarily as a symptom of mental illness, particularly schizophrenia. AIMS: This article explores whether, and how, public perception of an exaggerated association between voice hearing and mental illness might influence individuals' need for clinical care. METHOD: A narrative literature review was conducted, using relevant peer-reviewed research published in the English language...

INTRODUCTION: Ingestion of foreign bodies has been previously reported in some patients with schizophrenia. This behavior may be a manifestation of delusional beliefs or a response to command hallucinations and can lead to severe complications. CASE PRESENTATION: This paper reports a patient with schizophrenia who, as a manifestation of his illness, ingested a metallic skewer to kill ademon inside his abdomen that he believed was controlling him. As a result, he developed an acute intestinal perforation and underwent surgery...

Delirium tremens is a serious yet treatable complication of alcohol withdrawal. Timely diagnosis is critical as there are well-established treatment regimens that provide symptomatic relief within hours to days. We report the case of a 34-year-old man with an undisclosed history of alcohol dependency. He presented with paranoid beliefs and was transferred to a psychiatric inpatient unit with suspected schizophrenia. Classic features of delirium tremens such as sympathetic overdrive and visual hallucinations were not salient features of his presentation...

Current theories in the framework of hierarchical predictive coding propose that positive symptoms of schizophrenia, such as delusions and hallucinations, arise from an alteration in Bayesian inference, the term inference referring to a process by which learned predictions are used to infer probable causes of sensory data. However, for one particularly striking and frequent symptom of schizophrenia, thought insertion, no plausible account has been proposed in terms of the predictive-coding framework. Here we propose that thought insertion is due to an altered experience of thoughts as coming from "nowhere", as is already indicated by the early 20th century phenomenological accounts by the early Heidelberg School of psychiatry...

Frontotemporal degeneration (FTD) in its behavioral variant (bvFTD) is probably one of the conditions that best illustrates the links between psychiatry and neurology. It is indeed admitted that between a third and half of patients with this condition, especially in early-onset forms, receive an initial diagnosis of psychiatric disorder (depression, schizophrenia, bipolar disorder) and are then referred to a psychiatric ward. BvFTD can thus be considered a neurological disorder with a psychiatric presentation...

BACKGROUND: Schizophrenia is a psychiatric disorder characterized by positive and negative symptoms often accompanied by depression and cognitive deficits. Positive symptoms, like delusions and hallucinations are caused by an excess of dopamine (DA) signaling and are treated with the second generation antipsychotic drugs. Negative symptoms of schizophrenia are represented by social withdrawal, apathy and blunted emotional response. It was demonstrated that co-administration of risperidone and selective serotonin reuptake inhibitors alleviated depressive symptoms and cognitive dysfunction in animal models of schizophrenia...

Hallucinations are at the core of the diagnosis of schizophrenia and schizoaffective disorders, and many neuroscience studies focus on hallucinations. However, there is a lack of data on prevalence, subtyping, and clinical correlates of hallucinations as well as on the comparison of hallucinating schizophrenia versus hallucinating schizoaffective patients. Analysis of all psychopathology evaluations is based on the AMDP scale in a German psychiatric university hospital between 2007 and 2013 regarding patients with schizophrenia or schizoaffective disorder (diagnosed according to ICD-10)...

Recent neurobiological accounts of schizophrenia have included an emphasis on changes in sensory processing. These sensory and perceptual deficits can have a cascading effect onto higher-level cognitive processes and clinical symptoms. One form of sensory dysfunction that has been consistently observed in schizophrenia is altered temporal processing. In this study, we investigated temporal processing within and across the auditory and visual modalities in individuals with schizophrenia (SCZ) and age-matched healthy controls...

Heterogeneous findings across studies of structural abnormality in schizophrenia (SZ) have impeded the development a unified theory of white matter pathology. As a cardinal symptom of SZ, auditory verbal hallucination (AVH) has been suspected to be associated with improper communication among several brain regions, which might indicated white matter pathology. Participants comprised 25 first-episode (FE) patients with AVH, 25 patients without AVH and 25 healthy subjects. Diffusion tensor imaging (DTI) measures were calculated using the TBSS of FSL...

Auditory verbal hallucinations (AVH) are among the most characteristic symptoms of schizophrenia and have been linked to likely disturbances of structural and functional connectivity within frontal, temporal, parietal and subcortical networks involved in language and auditory functions. Resting-state functional magnetic resonance imaging (fMRI) has shown that alterations in the functional connectivity activity of the default-mode network (DMN) may also subtend hallucinations. Noninvasive neurostimulation techniques such as repetitive transcranial magnetic stimulation (rTMS) have the ability to modulate activity of targeted cortical sites and their associated networks, showing a high potential for modulating altered connectivity subtending schizophrenia...
