Auditory hallucinations constitute an important symptom component in 70-80% of schizophrenia patients. These hallucinations are proposed to occur due to an imbalance between perceptual expectation and external input, resulting in attachment of meaning to abstract noises; signal detection theory has been proposed to explain these phenomena. In this study, we describe the development of an auditory signal detection task using a carefully chosen set of English words that could be tested successfully in schizophrenia patients coming from varying linguistic, cultural and social backgrounds...

BACKGROUND: Methamphetamine psychosis (MAP) symptomatology has been described as indistinguishable from that of schizophrenia (SZ), yet research comparing these two disorders on specific psychotic symptoms such as schneiderian first-rank symptoms (FRS) is lacking. We aimed to determine and compare the occurrence and associations of FRS in patients diagnosed with MAP and with SZ. SAMPLING AND METHOD: Data from SCID-I interviews performed on patients with either a diagnosis of SZ or MAP were compared...

Literature has suggested that auditory hallucinations might be prevalent in the general population and could be linked to the experience of trauma. This prospective study examines the prevalence of auditory hallucinations in trauma survivors and its association with posttraumatic stress disorder (PTSD) symptoms, over time. Former prisoners-of-war (ex-POWs) from the 1973 Yom Kippur War (n = 99) with and without PTSD and comparable veterans (n = 103) were assessed twice, in 1991 (T1) and 2003 (T2) in regards to auditory hallucinations and PTSD symptoms...

Auditory hallucinations (AH) are a common and distressing experience and patients report distress reduction to be a priority. Relating Therapy adopts a symptom-specific and mechanism focused approach to the reduction of AH distress. We conducted this single-blind, pragmatic, parallel groups, superiority pilot RCT within a single mental health centre in the UK. Patients (18+years) with persistent and distressing AH, irrespective of diagnosis were randomly allocated to receive either Relating Therapy and Treatment-as-usual (RT) or Treatment as-usual alone (TAU)...

BACKGROUND: Folie à deux is a very rare psychiatric syndrome in which a psychotic symptom is transmitted from one individual to another. We present a case of folie à deux occurring during childhood, which is not an usual presentation of this syndrome. In this case, the disorder is correlated with child abuse and neglect, which possibly had a role in the development of the symptoms in our case. CASE PRESENTATION: We present a case of folie à deux between an "induced" 9-year-old black Brazilian boy and the "inducer", his grandmother...

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)...

Serotonergic hallucinogens, such as lysergic acid diethylamide (LSD), psilocybin, and N,N-dimethyltryptamine (DMT), are famous for their capacity to temporally and profoundly alter an individual's visual experiences. These visual alterations show consistent attributes despite large inter- and intra-individual variances. Many reports document a common perception of colors as more saturated, with increased brightness and contrast in the environment ("Visual Intensifications"). Environmental objects might be altered in size ("Visual illusions") or take on a modified and special meaning for the subject ("Altered self-reference")...

Objective. To increase student pharmacist empathy through the use of an auditory hallucination simulation. Design. Third-year professional pharmacy students independently completed seven stations requiring skills such as communication, following directions, reading comprehension, and cognition while listening to an audio recording simulating what one experiencing auditory hallucinations may hear. Following the simulation, students participated in a faculty-led debriefing and completed a written reflection. Assessment...

Eighty patients and thirty controls were interviewed using one interview that promoted personal disclosure and another about everyday topics. Speech was scored using the Thought, Language and Communication scale (TLC). All participants completed the Self-Concept Clarity Scale (SCCS) and the Varieties of Inner Speech Questionnaire (VISQ). Patients scored lower than comparisons on the SCCS. Low scores were associated the disorganized dimension of TD. Patients also scored significantly higher on condensed and other people in inner speech, but not on dialogical or evaluative inner speech...

Auditory verbal hallucinations (AVH) occur in psychotic disorders, but also as a symptom of other conditions and even in healthy people. Several current theories on the origin of AVH converge, with neuroimaging studies suggesting that the language, auditory and memory/limbic networks are of particular relevance. However, reconciliation of these theories with experimental evidence is missing. We review 50 studies investigating functional (EEG and fMRI) and anatomic (diffusion tensor imaging) connectivity in these networks, and explore the evidence supporting abnormal connectivity in these networks associated with AVH...

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)...

Recent decades have seen a surge of research interest in the phenomenon of healthy individuals who experience auditory verbal hallucinations, yet do not exhibit distress or need for care. The aims of the present systematic review are to provide a comprehensive overview of this research and examine how healthy voice-hearers may best be conceptualised in relation to the diagnostic versus 'quasi-' and 'fully-dimensional' continuum models of psychosis. A systematic literature search was conducted, resulting in a total of 398 article titles and abstracts that were scrutinised for appropriateness to the present objective...

Transcranial direct current stimulation (tDCS) is a technique of noninvasive cortical stimulation allowing significant modification of brain functions. Clinical application of this technique was reported for the first time in March 2005. This paper presents a detailed list of the 340 articles (excluding single case reports) which have assessed the clinical effect of tDCS in patients, at least when delivered to cortical targets. The reviewed conditions were: pain syndromes, Parkinson's disease, dystonia, cerebral palsy, post-stroke limb motor impairment, post-stroke neglect, post-stroke dysphagia, post-stroke aphasia, primary progressive aphasia, multiple sclerosis, epilepsy, consciousness disorders, Alzheimer's disease and other types of dementia, tinnitus, depression, auditory hallucinations and negative symptoms of schizophrenia, addiction and craving, autism, and attention disorders...

OBJECTIVE: In Alzheimer's disease, antipsychotic medications are often used for a period, with relief of symptoms, and then discontinued, after which relapse may occur. The authors sought to determine which neuropsychiatric symptoms predict relapse. METHOD: In the Antipsychotic Discontinuation in Alzheimer's Disease trial, 180 patients with Alzheimer's disease and symptoms of agitation or psychosis were treated with risperidone for 16 weeks, after which patients who responded (N=110) were randomly assigned to continue risperidone for 32 weeks, to continue risperidone for 16 weeks followed by switch to placebo for 16 weeks, or to receive placebo for 32 weeks...

BACKGROUND: Inner speech is a common human experience. Recently, there have been studies linking this experience with cognitive functions, such as problem solving, reading, writing, autobiographical memory, and some disorders, such as anxiety and depression. In addition, inner speech is recognised as the main source of auditory hallucinations. OBJECTIVES: The main purpose of this study is to establish the factor structure of Varieties of Inner Speech Questionnaire (VISQ) in a sample of the Colombian population...

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...
