Hallucination - Wikipedia, the free encyclopedia An hallucination is a sensory perception experienced in the absence of an external stimulus, as distinct from an illusion, which is a misperception of an external stimulus. Hallucinations may occur in any sensory modality - visual, auditory, olfactory, gustatory, tactile, or proprioception (sense of balance and position in space). Auditory hallucinations (particularly of one or more talking voices) are particularly associated with psychotic disorders such as schizophrenia, and hold special significance in diagnosing these conditions. en.wikipedia.org /wiki/Hallucination   (1149 words)

BEHAVIOURAL THEATMENT OF AUDITORY HALLUCINATIONS IN A SCHIZOPHERINIC PATIENT: A CASE STUDY Some studies have indicated that verbal auditory hallucinations tend to be associated with the concealed activity of the musculature responsible for speech, or "subvocalisations" (Green and Kinsbourne, 1990). The auditory hallucinations, according to the patient, consisted in hearing the voices of people who were not present at that moment, or who had died. We began by training him to cope with the auditory hallucinations experienced in the presence of traffic noise, since that was the condition with the highest rate of elicitation of hallucinations, and also the easiest to approach in the training sessions. www.psychologyinspain.com /content/full/1998/1bis.htm   (4578 words)

Auditory hallucinations These types of auditory hallucinations are not diagnostic in the same way as third person auditory hallucinations, but the content of the hallucination, and the patient's reaction to it, may help in diagnosis. In a depressive psychosis the comments from the auditory hallucination may be derisory ("you are useless"), and the patient may accept them as being justified. Gedankenlautwerden is an hallucination where a patient hears voices which anticipate what he or she is about to think, or which state what the patient is thinking as he thinks it. www.meta-religion.com /Neurology/hallucinations/auditory_hallucinations.htm   (328 words)

Studies on Hallucinations in Normals | Julian Jaynes Society Although the commentary hallucinations in the three patients were not distinctively different from the hallucinations that are characteristic of schizophrenia, the subjects were able to keep some distance from the hallucinations; in other words, the hallucinations were not ego-invasive. The commentary hallucinations in the present patients might be explained as resulting from exhaustion caused by stressful life events, subtle senile organic brain changes, and a subsequent decline in psychological tension. Auditory hallucinations not related to disease processes are common and may be highly valued by those who hear them. www.julianjaynes.org /relatedarticles_hallucinations.php   (2189 words)

The Neural Correlates of Auditory Hallucinations in Schizophrenia -- Neurotransmitter.net The Neural Correlates of Auditory Hallucinations in Schizophrenia -- Neurotransmitter.net Auditory sensory memory, which refers to the ability of the brain to retain transient representations of the physical features (e.g., pitch) of simple auditory stimuli for periods of up to approximately 30 sec, represents one of the simplest components of the brain working memory system. Auditory verbal imagery in general, as indexed by the three imagery tasks combined, was associated with activation in the areas engaged during the inner speech task, plus the left precentral and superior temporal gyri (STG), and the right homologues of all these areas. www.neurotransmitter.net /auditoryhallucinations.html   (16749 words)

Parkinson's Drug May Spur Hallucinations NEW YORK (Reuters) -- Auditory hallucinations (such as "hearing voices") may be a side effect of levodopa (L-dopa), the drug most commonly used to treat Parkinson's disease. Auditory hallucinations usually involved "hearing voices." The coherence of these voices varied from patient to patient. All of those afflicted with auditory phenomena were taking L-dopa or similar medications at the time, although the authors caution that "we cannot prove that the patients' symptoms were related to drugs." Discontinuing some antiparkinsonian medications or treatment with the antipsychotic clozapine were effective in preventing hallucinations in several patients. www.personalmd.com /news/a1998051102.shtml   (380 words)

Do You See What I Hear? Imaging Auditory Hallucinations The investigators examined 13 patients with acute schizophrenia and frequent auditory hallucinations (mean age, 33; eight men), 13 patients with acute schizophrenia and no reported hallucinations (mean age, 31; eight men), and 13 healthy control subjects (mean age, 32; eight men). The regions with higher fractional anisotropy in patients with schizophrenia and hallucinations were located in the lateral left and right temporoparietal section of the arcuate fasciculus close to the posterior end of the Sylvian fissure—where the Wernicke area is located—and close to the cortical auditory regions. One link between auditory hallucinations and inner speech is the common clinical observation that the content of auditory hallucinations is often closely related to the content of the patient’s own thought and sometimes is even reported as thoughts becoming loud,” she elaborated. www.neuropsychiatryreviews.com /aug04/npr_aug04_auditory.html   (727 words)

Neuroimaging of Schizophrenic Hallucinations | Julian Jaynes Society This supports the hypothesis that during hallucinations activation in cortical regions mediating the generation of inner speech may precede the engagement of areas implicated in the perception of auditory verbal material. Comparison of patients when experiencing severe hallucinations and when hallucinations were mild revealed reduced responsivity of the temporal cortex, especially the right middle temporal gyrus, to external speech during the former state. The auditory hallucinatory state is associated with reduced activity in temporal cortical regions that overlap with those that normally process external speech, possibly because of competition for common neurophysiological resources. www.julianjaynes.org /relatedarticles_neuroimaging.php   (1446 words)

Auditory Hallucinations Interview Guide   (Site not responding. Last check: 2007-10-30) A second aim of this study is to determine the effects of 10 behavioral strategies on the characteristics of auditory hallucinations. The main risks to subjects participating in this study are possible loss of privacy, an increase in auditory hallucinations especially during the beginning of the study, and discomfort from discussing and frequently monitoring their auditory hallucinations. The researchers will attempt to minimize the risks resulting from a possible increase in auditory hallucinations during the beginning of the study by telling subjects they may experience an increase in auditory hallucinations during the initial days of the study and discussing with them which strategies they will use if this happens. www.usfca.edu /nursing/schizophrenia6.html   (2959 words)

Treatments for Auditory Hallucinations: News: UI Health Care In the UI study on auditory hallucinations, the rTMS is being used to treat a different area of the brain - the temporal parietal region - and at a lower frequency of one pulse per second. When patients with auditory hallucinations are asked where they believe the voices are coming from, some may say it is a higher power or strangers. People with schizophrenia who have auditory hallucinations must be stable on their medications for the past month and continue on their medication regime throughout the study. www.uihealthcare.com /news/news/2004/11/29hallucinations.html   (834 words)

TMS Brasil ... Auditory hallucinations are reported by 50–70% of patients with schizophrenia and generally consist of spoken speech or voices. Endpoint hallucination ratings were analysed by use of a repeated measure ANOVA with two additional factors; order of stimulation (active or sham first), and concomitant treatment with anticonvulsant drugs. An earlier study showed that factors contributing to severity of auditory hallucinations varied between patients (for instance, frequency, loudness, content, number of voices,emotional distress, and level of distraction). transmagnet.med.br /mostra_resumos.php?seq=113   (906 words)

Hallucinations Hallucinations can be considered strong mental images that are experienced as if they were perceptions of external reality. The patient may experience auditory hallucinations of voices, a visual hallucination of objects, animals or people, a tactile hallucination of skin sensations or hallucinations of taste and smell.

Hypnagogic hallucinations - Patient UK Hypnagogic or hypnopompic hallucinations are visual, tactile, auditory, or other sensory events, usually brief but occasionally prolonged, that occur at the transition from wakefulness to sleep (hypnagogic) or from sleep to wakefulness (hypnopompic). Auditory hallucinations are common, but other senses are seldom involved. Musical release hallucinations are complex auditory phenomena, affecting mostly the deaf elderly population, in which individuals hear vocal or instrumental music. www.patient.co.uk /showdoc/40002314   (933 words)

Hallucinations Hallucinations are less likely to occur when the person is occupied or interested in what is going on around them. People who have persistent visual hallucinations together with stiffness and slowing of movement, or marked fluctuations in their abilities, are likely to have Lewy body dementia. As with visual hallucinations it is important to rule out possible causes such as physical illness and the side-effects of medication. easyweb.easynet.co.uk /vob/alzheimers/information/hallucinations.htm   (970 words)

Auditory Hallucinations Although most of the literature on malingering focuses on the forensic population, in the psychiatric emergency room we also see patients who report the presence of auditory hallucinations in order to obtain food and shelter, to receive medication, or perhaps simply to enjoy the benefits of a therapeutic mileu. Auditory hallucinations are among the most prominent and distressing symptoms of a psychotic episode. Among these assumptions were that visual hallucinations signified organic brain syndrome, toxic hallucinations were experienced as outside the head, and nontoxic or endogenous hallucinations were considered by the patient to be inside. www.inch.com /~jholland/julie/papers/paper1.html   (1490 words)

Ask the Expert The simple fact is that when auditory hallucinations are part of the schizophrenic syndrome, they are often resistant to antipsychotic medication. These are usually fragments of actual auditory impressions recorded at the time of the trauma (e.g., rape, mugging) and will not usually require antipsychotic medication. However, patients who hear command auditory hallucinations of a threatening or destructive nature are at risk for "acting out" in dangerous ways. www.mhsource.com /expert/exp1071601d.html   (402 words)

Auditory Processing in Schizophrenia Auditory hallucinations are a cardinal and disabling symptom of schizophrenia; their pathophysiology remains unknown. We tested the hypothesis that a mechanism of auditory hallucination in schizophrenic patients results from the loss of automatic inhibition of auditory processing of self-generated speech. All were psychotic (auditory hallucinations and/or delusions) at the time of the study. james.psych.umn.edu /auditory_process_schiz.html   (607 words)

Hallucinations Hallucinations are abnormal sensory perceptions that occur while a person is awake and conscious. Auditory hallucinations are more common in psychotic conditions such as schizophrenia, although they may sometimes be associated with high doses of cocaine, amphetamine or other stimulants. A person who is hallucinating may become agitated, paranoid, and frightened, and should not be left alone. www.healthscout.com /ency/1/003258.html   (279 words)

Hallucinations Information on Healthline Hallucinations are sensory perceptions that are unrelated to outside events -- in other words, seeing or hearing things that aren't there. Hallucinations related to smell or taste are rare. Hallucinations related to these drugs tend to be visual, such as geometric patterns or haloes around lights. www.healthline.com /adamcontent/hallucinations   (618 words)

clinical & research news The left temporoparietal cortex is known to be critical to the perception of spoken speech, the thalamus to be involved in auditory processing, and the hippocampus to engage in short-term memory functions necessary for tracking speech over a period of time. If their hallucinations were more severe, they gave them a number greater than 10, but if their hallucinations were less severe, they gave them a number less than 10. Their hallucinations were once again assigned the number 10, and after they got each sham treatment they were asked to rate their hallucinations compared with how they had been at the start of the sham trial. www.psych.org /pnews/00-06-02/treat.html   (1022 words)

Auditory Hallucinations: What's It Like Hearing Voices? This foray into the uncanny is as close as most people come to experiencing auditory hallucinations or “hearing voices,” a condition that affects 70% of patients with schizophrenia and 15% of patients with mood disorders such as mania or depression. But hearing voices is not necessarily a sign of mental illness, so understanding the mechanics of auditory hallucinations is crucial to understanding schizophrenia and related disorders. Hallucinated voices are also known to occur during states of religious or creative inspiration. www.concernedcounseling.com /communities/thought_disorders/schizo/articles/hearing_voices.asp   (1038 words)

Auditory Hallucinations Before the onset of the disease, she had been having auditory/visual hallucinations, and feelings of paranoia. All the while she was still having the auditory hallucinations.

Hear my song: auditory hallucinations with tramadol hydrochloride British Medical Journal - Find Articles These were particularly vivid and took the form of "two voices singing, accompanied by an accordion and a banjo, singing songs, songs by Josef Locke--old songs." They were distressing, making him feel as though he was going mad. Tramadol is a centrally acting opioid analgesic which has been available in the United Kingdom since 1994 and is licensed for use orally or by injection for the treatment of moderate to severe pain.[3] Experience of the use of this drug in Britain is limited, although it has been available for some years in Germany. Musical hallucinations are well described in elderly people, though predominantly in women or in those with depression or hearing impairment.[7] In the absence of these other possible causes and with a clear temporal relation to the administration of tramadol, we conclude that the tramadol was the cause of the hallucinations. www.findarticles.com /p/articles/mi_m0999/is_7276_321/ai_69057220   (491 words)
