Persistent auditory verbal hallucinations (AVH) in schizophrenia are increasingly tied to dysfunction at the level of auditory cortex. AVH may reflect in part misattribution of internally generated thoughts to external spatial locations. Here, we investigated the association between persistent AVH and spatial localization abilities assessed both behaviorally and by mismatch negativity (MMN) to location deviants. METHODS: Spatial- and tonal- discrimination abilities were assessed in patients (n=20) and controls (n=20) using free-field tones...

OBJECTIVE: Despite strong evidence supporting the effectiveness of cognitive-behavioral therapy for psychosis (CBTp), most clinicians in the United States have received little or no training in the approach and access remains very low, indicating a potential role for technology in increasing access to this intervention. Coping With Voices (CWV) is a 10-session, interactive, Web-based CBTp skills program that was developed to meet this need, and was shown to be feasible and associated with reduced severity of auditory hallucinations in a previous pilot study...

Previous studies showed a global reduction of the event-related potential component N100 in patients with schizophrenia, a phenomenon that is even more pronounced during auditory verbal hallucinations. This reduction assumingly results from dysfunctional activation of the primary auditory cortex by inner speech, which reduces its responsiveness to external stimuli. With this study, we tested the feasibility of enhancing the responsiveness of the primary auditory cortex to external stimuli with an upregulation of the event-related potential component N100 in healthy control subjects...

OBJECTIVES: Cognitive models propose that levels of distress associated with auditory verbal hallucinations ('voices') are influenced by the hearers' beliefs about their voices (perceived malevolence and omnipotence), their negative beliefs about themselves and others and their attachment style. This study aims to test a comprehensive model of the relationship between these variables in order to identify distal and proximal interpersonal and cognitive factors contributing to voice-related distress...

Data from 247 first-episode psychosis patients were used to explore associations between types of hallucinations and nine diverse clinical characteristics. Psychopathology was rated using the Scale for the Assessment of Positive Symptoms and Scale for the Assessment of Negative Symptoms (SANS). Childhood adversity was assessed with seven instruments; family history with an adapted version of the Family Interview for Genetic Studies; age at onset of psychosis and duration of untreated psychosis (DUP) with the Symptom Onset in Schizophrenia inventory; and insight with the Birchwood Insight Scale...

Voriconazole, a broad-spectrum antifungal, has been associated with visual and auditory hallucinations. We report the case of patient being treated with voriconazole for pulmonary aspergillosis who developed visual hallucinations and new suicidal ideation with plan. Voriconazole troughs were supratherapeutic (9.0 mcg/mL) and the patient was positive for the CYP2C19*1/*2 allele.

Abnormalities in self-other voice processing have been observed in schizophrenia, and may underlie the experience of hallucinations. More recent studies demonstrated that these impairments are enhanced for speech stimuli with negative content. Nonetheless, few studies probed the temporal dynamics of self versus nonself speech processing in schizophrenia and, particularly, the impact of semantic valence on self-other voice discrimination. In the current study, we examined these questions, and additionally probed whether impairments in these processes are associated with the experience of hallucinations...

High levels of anxiety were found to interfere with voice hearers' ability to benefit from a 10-Session Behavioral Management of Auditory Hallucinations Course. The 10-session course was revised, adding anxiety reduction strategies to the first four classes and reinforcing those strategies in the remaining eight classes. A multi-site study (N = 27) used repeated measures to determine whether the new 12-session course would significantly reduce anxiety. Ten course leaders were trained and taught the course six times at three different outpatient mental health sites...

INTRODUCTION: Efficacy of repetitive Transcranial Magnetic Stimulation (rTMS) targeting the temporo-parietal junction (TPJ) for the treatment of auditory verbal hallucinations (AVH) remains under debate. We assessed the influence of a 1Hz rTMS treatment on neural networks involved in a cognitive mechanism proposed to subserve AVH. METHODS: Patients with schizophrenia (N=24) experiencing medication-resistant AVH completed a 10-day 1Hz rTMS treatment. Participants were randomized to active stimulation of the left or bilateral TPJ, or sham stimulation...

Brodmann areas 41 and 42 are located in the superior temporal gyrus and regarded as auditory cortices. The fundamental function in audition is frequency analysis; however, the findings on tonotopy maps of the human auditory cortex were not unified until recently when they were compared to the findings on inputs and outputs of the monkey auditory cortex. The auditory cortex shows plasticity after conditioned learning and surgery of cochlear implant. It is also involved in speech perception, music appreciation, and auditory hallucination in schizophrenia through interactions with other brain areas, such as the thalamus, frontal cortex, and limbic systems...

BACKGROUND: Malignant catatonia (MC) is a disorder consisting of catatonic symptoms, hyperthermia, autonomic instability, and altered mental status. Neuroleptic malignant syndrome (NMS) caused by antipsychotics is considered a variant of MC. Benzodiazepine (BZD) medications are safe and effective treatments providing rapid relief from MC. This case study reports a detailed clinical course of a case of MC associated with schizophrenia initially diagnosed as NMS that responded successfully to BZDs but not to dantrolene...

We present one of the first quantitative studies on auditory verbal experiences ("hearing voices") and auditory verbal agency (inner speech, and specifically "talking to (imaginary) voices or characters") in healthy participants across states of consciousness. Tools of quantitative linguistic analysis were used to measure participants' implicit knowledge of auditory verbal experiences (VE) and auditory verbal agencies (VA), displayed in mentation reports from four different states. Analysis was conducted on a total of 569 mentation reports from rapid eye movement (REM) sleep, non-REM sleep, sleep onset, and waking...

In order to identify causes and triggers of hallucinations that can inform therapy, reliable, valid, and change-sensitive instruments to assess hallucinatory experiences in the subclinical and clinical range are needed. We developed and validated a novel scale, the Continuum of Auditory Hallucinations - State Assessment (CAHSA), to be used for repeated assessment of the subclinical factors vivid imagination, intrusive thoughts, and perceptual sensitivity as well as auditory hallucinations. After selecting items for the four factors in a first test sample (n=84), we tested factorial validity using CFA and criterion validity with self-reported psychosis-like experiences (n=534)...

Mephedrone (4-methylmethcathinone), a constituent of the recreational substances known as "bath salts", is a synthetic cathinone that can produce auditory and visual hallucinations, as well as problematic cardiovascular effects. This study compared the discriminative stimulus effects of mephedrone (0.32-10 mg/kg) with other prototypical drugs of abuse: cocaine (0.56-32 mg/kg), d-amphetamine (0.18-3.2 mg/kg), ketamine (1.8-18 mg/kg), phencyclidine (PCP, 1-5.6 mg/kg), heroin (1-10 mg/kg), 2,5-dimethoxy-4-iodoamphetamine (R-DOI, 0...

Hearing voices in the absence of another speaker-what psychiatry terms an auditory verbal hallucination-is often associated with a wide range of negative emotions. Mainstream clinical research addressing the emotional dimensions of voice-hearing has tended to treat these as self-evident, undifferentiated and so effectively interchangeable. But what happens when a richer, more nuanced understanding of specific emotions is brought to bear on the analysis of distressing voices? This article draws findings from the 'What is it like to hear voices' study conducted as part of the interdisciplinary Hearing the Voice project into conversation with philosopher Dan Zahavi's Self and Other: Exploring Subjectivity, Empathy and Shame to consider how a focus on shame can open up new questions about the experience of hearing voices...

The Psychotic Symptom Rating Scales (PSYRATS) is a clinical assessment tool that focuses on the detailed measurement of delusions and hallucinations in patients with psychosis. The goal of this study was to examine the psychometric properties of the Portuguese version of the PSYRATS. A sample of 92 outpatients suffering from schizophrenia or schizoaffective disorders and presenting persistent psychotic symptoms was assessed using the PSYRATS and the Positive and Negative Syndrome Scale (PANSS). Good inter-rater reliability, test-retest reliability, concurrent validity and internal consistency were found...

BACKGROUND: Auditory verbal hallucinations (AVHs) played an important role in the psychiatric diagnostics, but in the last few decades the diagnostic-free complex phenomenological understanding of the phenomena of voice hearing became the focus of studies. MATERIALS: Six semi-structured interviews with recovering voice hearers were conducted and analysed using interpretative phenomenological analysis (IPA). DISCUSSION: The self-help group gives significant help in identification and dealing with the voices; therefore, it serves as turning point in the life story of voice hearers...
