So Fujimoto, Yutaka Komura
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)...

OBJECTIVE: This study aimed to examine the alterations of cortical connectivity in first-episode schizophrenia (FES) with auditory hallucinations at early response of antipsychotics. METHODS: This was a nonexperimental control of medication study. We measured the cortical activity of 20 medicated patients with FES (medicated group), 19 nonmedicated patients with FES (nonmedicated group), and 22 healthy controls using electroencephalogram during eye-open resting state...

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...

We have provided 3-D and 4D mapping of speech and language function based upon the results of direct cortical stimulation and event-related modulation of electrocorticography signals. Patients estimated to have right-hemispheric language dominance were excluded. Thus, 100 patients who underwent two-stage epilepsy surgery with chronic electrocorticography recording were studied. An older group consisted of 84 patients at least 10 years of age (7367 artefact-free non-epileptic electrodes), whereas a younger group included 16 children younger than age 10 (1438 electrodes)...

We report a case of a 57-year-old male patient with intrathecal morphine pump failure who presented with psychosis as part of a clinical presentation of opioid withdrawal. The patient was being treated for chronic back pain with an intrathecal morphine pump for several years. The patient spontaneously started to experience psychotic symptoms which included disorganized thinking, delusional thoughts, paranoia, auditory and visual hallucinations. Upon interrogation of intrathecal pump, it was found not to be functioning, thereby not delivering intrathecal morphine...

OBJECTIVE: To explore the efficacies of 1-Hz (low frequency) and 10-Hz (high frequency) repetitive transcranial magnetic stimulation (rTMS) in treating auditory hallucinations and negative symptoms of schizophrenia, respectively. METHODS: Electronic databases were searched to identify relevant literature. Standard mean difference (SMD) and 95% confidence interval (CI) values were used to evaluate the effects of rTMS. The stability and sensitivity of the results, the source of heterogeneity, and the recommended grade of the evidence were also analyzed...

BACKGROUND AND OBJECTIVES: The purpose of this study was to evaluate the extent of short-term memory impairment and schizophrenia-like symptoms in heavy and systematic cannabis users and the association between the severity of abuse and the longevity of its persistent symptoms after refraining from such use. METHODS: A complete psychiatric examination and a psychometric evaluation were performed in 48 solely cannabis users. Additionally, head hair samples were analyzed and the detected cannabinoids levels were correlated with the psychometric findings...

In its classic presentation, Hashimoto's encephalopathy is an acute-subacute complex neuropsychiatric syndrome with cognitive impairment, hallucinations, myoclonus, tremor or ataxia, associated with elevated anti-thyroid antibodies. Corticoids and immunotherapy are dramatically effective. However, in some cases, not all the associated features are presented and this delays diagnosis and appropriate treatment. We describe a man with abrupt onset of recurrent auditory seizures resulting in refractory non-convulsive status epilepticus...

We examined the lifetime experience of hallucinations and delusions associated with transient methamphetamine-related psychosis (MAP), persistent MAP and primary psychosis among a cohort of dependent methamphetamine users. Participants were classified as having (a) no current psychotic symptoms, (n=110); (b) psychotic symptoms only when using methamphetamine (transient MAP, n=85); (c) psychotic symptoms both when using methamphetamine and when abstaining from methamphetamine (persistent MAP, n=37), or (d) meeting DSM-IV criteria for lifetime schizophrenia or mania (primary psychosis, n=52)...

BACKGROUND: Auditory Verbal Hallucinations (AVH) in children and adolescents are a relatively common and mostly transient feature in community samples. However, it should not be regarded as a merely benign phenomenon, as childhood AVH are associated with psychopathology. Little is known about the clinical group of children seeking help for AVH. This brings uncertainty on how to assess and treat these children. METHODS: This study describes the characteristics of 95 help-seeking children (aged 6 to 18years) with AVH attending an outpatient clinic specifically dedicated to help youth with this complaint...

Hallucinations are elusive phenomena that have been associated with psychotic behavior, but that have a high prevalence in healthy population. Some generative mechanisms of Auditory Hallucinations (AH) have been proposed in the literature, but so far empirical evidence is scarce. The most widely accepted generative mechanism hypothesis nowadays consists in the faulty workings of a network of brain areas including the emotional control, the audio and language processing, and the inhibition and self-attribution of the signals in the auditive cortex...
