Topiramate (TPM) is an antiepileptic drug also used in migraine prophylaxis (Silberstein et al. 2007). Neuropsychiatric symptoms may emerge during the use of TPM (Fröscher et al. 2005). There are few reports showing a link between psychotic adverse events and use of TPM (Khan et al. 1999). Only one patient with schizoaffective disorder has been reported in the litera ture, who complained of dos...

Distortion of the sense of reality, actualized in delusions and hallucinations, is the key feature of psychosis but the underlying neuronal correlates remain largely unknown. We studied 11 highly functioning subjects with schizophrenia or schizoaffective disorder while they rated the reality of auditory verbal hallucinations (AVH) during functional magnetic resonance imaging (fMRI). The subject...

College students screened for hallucination-proneness using the Launay-Slade Hallucination Scale (LSHS) were compared on measures of self-report vividness of imagery and on behavioral measures of imagery and perception (visual and auditory). Specifically, we tested the hypothesis whether hallucination-prone individuals would show smaller differences between imagery and perception performance, w...

Numerous studies have found that hallucinatory experiences occur in the general population. But to date, few studies have been conducted to compare clinical and nonclinical groups across a broad array of clinical symptoms that may co-occur with hallucinations. Likewise, hallucination-like experiences are measured as a multidimensional construct, with clinical and subclinical components related ...

Musical hallucination is a type of complex auditory hallucination. Possible etiologies are deafness, psychiatric disorders such as schizophrenia, major depression, use of medication and stress, besides neurologic diseases including epilepsy, stroke and cancer. Uncommon etiologies encompass infectious diseases, metabolic disorders, and sensory deprivation. Although musical hallucinations have a ...

This article presents a report on the first meeting of the International Consortium on Hallucination Research, which took place on September 13-14, 2011 at the Institute of Psychiatry, London. The first day of the meeting served to reflect on the current state of knowledge regarding auditory hallucinations in different diagnostic groups, based on the presentations from the phenomenology, cognit...

Do self-monitoring accounts, a dominant account of the positive symptoms of schizophrenia, explain auditory verbal hallucination? In this essay, I argue that the account fails to answer crucial questions any explanation of auditory verbal hallucination must address. Where the account provides a plausible answer, I make the case for an alternative explanation: auditory verbal hallucination is no...
