BACKGROUND Hallucinations occur in 20-40% of PD patients and have been associated with unfavorable clinical outcomes (i.e., nursing home placement, increased mortality). Hallucinations, like other non-motor features of PD, are not well recognized in routine primary/secondary clinical practice. So far, there has been no instrument for uniform characterization of hallucinations in PD. To this end...

INTRODUCTION Auditory hallucinations are a hallmark symptom of schizophrenia. The neural basis of auditory hallucinations was examined using data from a working memory task. Data were acquired within a multisite consortium and this unique dataset provided the opportunity to analyze data from a large number of subjects who had been tested on the same procedures across sites. We hypothesized that...

BACKGROUND Complex auditory hallucinations have rarely been reported in cases of brainstem stroke or tumor. METHOD Case study. RESULTS A patient with acute Listeria rhombencephalitis complained of formed musical auditory hallucinations on the side of recent sensorineural deafness. MRI revealed an abscess in the middle cerebellar peduncule with extensive surrounding edema. CONCLUSIONS Disr...

While it has long been recognized that certain hallucinations accompanying a high fever or epilepsy or appearing as a side effect of medication are common in childhood, it is only recently becoming clear that hallucinations may also occur as a feature of common psychiatric disorder without the unfavorable prognosis of childhood psychosis. The case described below illustrates some of the charact...

As part of a prospective natural history cohort study of voriconazole toxicity, we describe the characteristics of 12 of 72 voriconazole-treated patients who experienced hallucinations from March 2006 through November 2007. Hallucinations associated with voriconazole use are not uncommon. Doctors should be aware of this complication, and the recipients of the drug should be reassured that the h...

Decreased language lateralization is a well-replicated finding in psychotic patients. It is currently unclear, however, whether this abnormality is related to a particular symptom of psychosis or to psychosis in general. It has been argued that decreased language lateralization may be related to auditory verbal hallucinations. To elucidate this, these hallucinations should be studied in isolati...

BACKGROUND Auditory hallucinations are resistant to pharmacotherapy in about 25% of adults with schizophrenia. Treatment with noninvasive brain stimulation would provide a welcomed additional tool for the clinical management of auditory hallucinations. A recent study found a significant reduction in auditory hallucinations in people with schizophrenia after five days of twice-daily transcranial...

• 254 • • Forum • The experience of auditory hallucinations, especially verbal hallucinations, is a common psychotic symptom in persons with schizophrenia, but in about 30% of these individuals traditional treatment with antipsychotic medication is not effective in reducing the hallucinations. For this subgroup of patients, alternative forms of treatment need to be assessed. The occurrence of a...

BACKGROUND Visual hallucinations in Parkinson disease (PD) occur in approximately one third of patients treated long-term with dopaminergic medications. In Alzheimer disease, hallucinations and psychosis have been linked to increased representations of B2/B2 homozyogotes for the dopamine receptor gene DRD1 and 1/1 or 2/2 homozygotes for DRD3. In addition, a previous study of PD patients with an...

Musical hallucinations (MH) are complex phenomena that are associated with hearing loss, brain disease (glioma, epilepsy, cerebrovascular disease, encephalitis), and psychiatric disorders such as major depressive disorder, bipolar disease, and schizophrenia. MH are also commonly seen in people without otorhinolaryngological, neurological, or mental illness pathology.1 In his novel Musicophilia,...
