Descriptions of hallucinatory phenomena have figured prominently since the beginning of recorded history. Jean Etienne Esquirol (1772-1840) is usually credited for having introduced the term in 1817, differentiating between hallucinations and illusions. Both are wrong perceptions, but in illusions, an external stimulus is always present whereas hallucinations are perceptions that occur in the absence of corresponding sensory stimuli. They occur in a variety of conditions but more often in the mentally ill, especially in schizophrenia where hallucinations, particularly auditory hallucinations represent for many, such as Henri Ey one of the cardinal features...

Simon McCarthy-Jones
BACKGROUND: Whilst evidence is mounting that childhood sexual abuse (CSA) can be a cause of auditory verbal hallucinations (AVH), it is unclear what factors mediate this relation. Recent evidence suggests that post-traumatic symptomatology may mediate the CSA-AVH relation in clinical populations, although this hypothesis has not yet been tested in the general population. There is also reason to believe that obsessive ideation could mediate the CSA-AVH relation. AIMS: To test for evidence to falsify the hypotheses that post-traumatic symptomatology, obsessions, compulsions, anxiety and depression mediate the relation between CSA and AVH in a general population sample...

AIM: To improve public understanding of the subjective experience of auditory hallucinations and increase empathy towards individuals who hear voices and have other unusual sensory experiences. METHODS: This pilot study developed a new immersive art exhibition, Altered States of Consciousness, which gave members of the public an individualized voice-hearing simulation experience in 2 real-world settings-an art gallery and the London Underground. A total of 150 visitors completed visual analogue scales immediately before and after their experience of the exhibition...

Poor cognitive insight in schizophrenia has been linked to delusions, hallucinations, and negative symptoms as well as to depressive/anxiety symptoms. Its impact on quality of life has been less studied, especially in schizophrenia subjects with ongoing auditory hallucinations. The Beck Cognitive Insight Scale (BCIS) and the Quality of Life Scale (QLS) were administered to subjects who met DSM IV criteria for schizophrenia after due translation and validation. All subjects reported ongoing auditory hallucinations at recruitment...

Psychotic disorders are characterized by auditory verbal hallucinations (AVHs), and research has shown that AVHs are linked to deficits in working memory. Our understanding of AVHs across the psychosis continuum is limited. To date, little research has tested whether hallucination proneness (HP) is linked with abnormalities on experimental multispeaker babble tasks. Few investigations have been conducted to determine how task performance might be linked to cognitive functioning. The objective of the current study is to better understand this empirical gap...

REVIEW
Fady Rachid
Theta-burst stimulation (TBS) is a form of repetitive transcranial magnetic stimulation and is thought to induce more rapid and longer-lasting effects on synaptic plasticity than conventional repetitive transcranial magnetic stimulation protocols. TBS is being used as an investigational and more recently as a therapeutic tool. The purpose of this review is to describe and discuss the studies that have evaluated the safety and efficacy of this technique in the treatment of various psychiatric disorders such as depression, schizophrenia, obsessive-compulsive disorder, Tourette's disorder, nicotine and cocaine addiction, and pathological gambling...

Kenneth Hugdahl, Iris E Sommer
In the present article, we present a "Levels of Explanation" (LoE) approach to auditory verbal hallucinations (AVHs) in schizophrenia. Mental phenomena can be understood at different levels of explanation, including cultural, clinical, cognitive, brain imaging, cellular, and molecular levels. Current research on AVHs is characterized by accumulation of data at all levels, but with little or no interaction of findings between levels. A second advantage with a Levels of Explanation approach is that it fosters interdisciplinarity and collaboration across traditional borders, facilitating a real breakthrough in future research...

To establish the point prevalence of hallucinations in borderline personality disorder (BPD), telephone interviews were conducted with 324 outpatients diagnosed with BPD. Then a subgroup (n = 98) was interviewed in person to investigate the co-occurrence of these phenomena with other psychotic symptoms, comorbid psychiatric disorders, prior childhood adversities, and adult life stressors. For hallucinations in general a point prevalence of 43% was found, with rates for hallucinations in separate sensory modalities ranging from 8-21%...

The present study examined serum levels of adenosine deaminase (ADA), an adenosine metabolizing enzyme, in neuroleptic-naive patients with recent-onset schizophrenia and age-matched healthy comparison subjects. ADA levels were found to be higher among patients, and revealed a possible link between evening rise and severity of auditory hallucinations as well as morning rise and severity of avolition-apathy in patients with schizophrenia. These findings suggest the potential utility of serum ADA as a peripheral biomarker of schizophrenia...

Auditory verbal hallucinations (hearing voices) are typically associated with psychosis, but a minority of the general population also experience them frequently and without distress. Such 'non-clinical' experiences offer a rare and unique opportunity to study hallucinations apart from confounding clinical factors, thus allowing for the identification of symptom-specific mechanisms. Recent theories propose that hallucinations result from an imbalance of prior expectation and sensory information, but whether such an imbalance also influences auditory-perceptual processes remains unknown...

The pathophysiology of auditory hallucination, a common symptom of schizophrenia, has yet been understood, but during auditory hallucination, primary auditory cortex (A1) shows paradoxical responses. When auditory stimuli are absent, A1 becomes hyperactive, while A1 responses to auditory stimuli are reduced. Such activation pattern of A1 responses during auditory hallucination is consistent with aberrant gamma rhythms in schizophrenia observed during auditory tasks, raising the possibility that the pathology underlying abnormal gamma rhythms can account for auditory hallucination...

BACKGROUND: Few patients have access to cognitive behaviour therapy for psychosis (CBTp) even though at least 16 sessions of CBTp is recommended in treatment guidelines. Briefer CBTp could improve access as the same number of therapists could see more patients. In addition, focusing on single psychotic symptoms, such as auditory hallucinations ('voices'), rather than on psychosis more broadly, may yield greater benefits. METHOD: This pilot RCT recruited 28 participants (with a range of diagnoses) from NHS mental health services who were distressed by hearing voices...

OBJECTIVES: The main goal of the present study was to explore the associations between several key variables that have been shown to partially mediate the link between specific trauma exposure and auditory hallucinations (AH), that is, maladaptive schemas and dissociation in the general population. METHODS: In total, 425 voluntary participants were recruited from the general population and completed online the Childhood Trauma Questionnaire, the Young schema questionnaire, the Dissociative Experiences Scale, and the Launay-Slade Hallucination Scale...

In this invited review article I present a translational perspective and overview of our research on auditory hallucinations in schizophrenia at the University of Bergen, Norway with a focus on the neuronal mechanisms underlying the phenomenology of experiencing "hearing voices". An auditory verbal hallucination, i.e. "hearing a voice", is defined as a sensory experience in the absence of a corresponding external sensory source that could explain the phenomenological experience. I suggest a general frame or scheme for the study of auditory verbal hallucinations which is called Levels of Explanation (LoE)...

This study was aimed to explore self-report auditory verbal hallucinations to provide unique and valuable information in addition to clinician-rated assessment in patients with schizophrenia. The VAGUS (http://www.vagusonline.com) is a recently developed insight scale that includes both clinician-rated (CR) and self-report (SR) versions. Insight measures obtained by the two versions of the VAGUS from the clinicians and the patients, respectively, in forty-one patients diagnosed with schizophrenia by DSM-IV-TR criteria were compared...

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...

Humans possess a basic need to belong and will join groups even when they provide no practical benefit. Paranoid symptoms imply a disruption of the processes involved in belonging and social trust. Past research suggests that joining social groups and incorporating those groups into one's identity (social identification) promotes positive self-views and better physical and mental health. However, no research has investigated whether social identity is associated with paranoia, nor the mechanisms by which this effect may emerge...

Although altered consciousness and other neurologic manifestations are frequently seen in hypertensive encephalopathy, behavioral and psychotic symptoms are rarely seen. We describe a patient with no previous psychiatric history who was admitted for hypertensive crisis. A few days after admission, his blood pressure remained uncontrolled and he started to exhibit episodes of confusion, agitation, and psychosis. During one particular episode, he overcame multiple staff members and physical restraints to bite off two of his fingers without any signs of pain...

We report a case in a young man who developed acute, persistent and painful tongue protrusion followed by swelling for more than 24 hours. He had relapse symptoms of schizophrenia and had recently received a single dose of parenteral haloperidol to manage his agitation. His record showed history of similar event and he has been taking atypical antipsychotic for maintenance. Mental state examination on admission revealed an agitated man with disorganised speech, restricted affect, auditory hallucination and persecutory delusion...
