Release hallucination

Jang-Ho Park, Joon-Ho Ahn, Jun-Bum Park, Soohyun Joe
Charles Bonnet syndrome (CBS) can develop after trans-sphenoidal adenomectomy (TSA); however, the neural mechanisms remain unknown. Sensory deprivation and releasing phenomenon are both hypothetical explanations for this condition; however, there is no definite evidence that strongly supports either supposition. We report the first case of CBS after TSA without optic nerve atrophy. Postoperatively, the patient's vision seemed to be relatively well preserved, apart from the left-side hemianopsia in the right eye...

BACKGROUND: Schizophrenia is a psychiatric disorder characterized by positive and negative symptoms often accompanied by depression and cognitive deficits. Positive symptoms, like delusions and hallucinations are caused by an excess of dopamine (DA) signaling and are treated with the second generation antipsychotic drugs. Negative symptoms of schizophrenia are represented by social withdrawal, apathy and blunted emotional response. It was demonstrated that co-administration of risperidone and selective serotonin reuptake inhibitors alleviated depressive symptoms and cognitive dysfunction in animal models of schizophrenia...

Functional MRI studies have identified a distributed set of brain activations to be associated with auditory verbal hallucinations (AVH). However, very little is known about how activated brain regions may be linked together into AVH-generating networks. Fifteen volunteers with schizophrenia or schizoaffective disorder pressed buttons to indicate onset and offset of AVH during fMRI scanning. When a general linear model was used to compare blood oxygenation level dependence signals during periods in which subjects indicated that they were versus were not experiencing AVH ("AVH-on" versus "AVH-off"), it revealed AVH-related activity in bilateral inferior frontal and superior temporal regions; the right middle temporal gyrus; and the left insula, supramarginal gyrus, inferior parietal lobule, and extranuclear white matter...

Recent advances in the understanding of psychosis have uncovered potential for a paradigm shift in related drug discovery efforts. The study of psychosis is evolving from its origins in serendipity and empiricism to more formal, hypothesis driven accounts of the cognitive substrates underlying hallucinations and delusions. Recent evidence suggests that misattribution of salience and abnormal prediction error might underlie some forms of psychosis. If substantiated, such intermediate constructs could significantly facilitate translational research for drug discovery...

RATIONALE: Toluene is a misused inhalant with hallucinogenic properties and complex effects. Toluene blocks N-methyl-D-aspartate (NMDA) receptors, releases dopamine (DA), and modifies several neurotransmitter levels; nonetheless, the mechanism by which it produces hallucinations is not well characterized. OBJECTIVES: This study aims (a) to study toluene's effects on the 5-HT2A-mediated head-twitch response (HTR), dopamine (DA), and serotonin (5-HT) tissue levels in discrete brain regions; (b) to compare the actions of toluene, ketamine, and 1-[2,5-dimethoxy-4-iodophenyl]-2-aminopropane (DOI) on HTR; and (c) to study the pharmacological blockade of toluene's and ketamine's effects by selective drugs...

BACKGROUND: Visual hallucinations (VH) are common in Parkinson's disease (PD) and are associated with increased morbidity and mortality. Current explanations for VH in PD suggest combined impairments in top-down attentional and bottom-up perceptual processes, which allow the passive "release" of stored images. Alternative models in other disorders have suggested that top-down factors may actively encourage hallucinations. In order to explore the interaction between top-down and bottom-up visual processing in PDVH, we developed novel experimental priming tasks in which top-down verbal cues were used to prime the bottom-up recognition of partial or ambiguous pictures...

Non-physiological, excessive dopaminergic stimulation can cause dyskinesia-hyperpyrexia syndrome (DHS), which was initially reported by Gil-Navarro and Grandas in 2010. A 70-years-old woman with a 13-years history of Parkinson's disease (PD) was hospitalized due to difficulty walking, despite being treated with levodopa/carbidopa (600 mg/day), immediate-release pramipexole (3 mg/day), and selegiline (5 mg/day). Immediate-release pramipexole was changed to extended-release pramipexole without changing the dose or levodopa equivalent dose (LED)...

Auditory musical hallucinations (AMHs) are rare complex auditory hallucinations in Parkinson's disease (PD) that have been limited previously. The characteristics of AMHs in PD remain uncertain. We describe a 72-year-old woman with PD who presented with AMHs. The AMHs occurred after immediate-release pramipexole was switched to extended-release pramipexole. The AMHs were a quiet piano or often songs on a loud radio or background music over other sounds. The music was unpleasant, but not objectionable, threatening, or ego-syntonic, and it did not interrupt her daily activities...

Depression is an affective disorder characterized by hallucination, delusion and increased social risk and is estimated to affect approximately 20 % of the population at some point during the lifetime. As per World Health Organization (WHO) it is predicted to be the leading cause of burden of disease by 2030. Effects of currently available antidepressants have explained the monoamine hypothesis of depression, which proposes that impaired release of serotonin, noradrenaline and dopamine, are thought to be responsible for the development of depressive symptoms...

Substituted cathinones are synthetic analogs of cathinone that can be considered as derivatives of phenethylamines with a beta-keto group on the side chain. They appeared in the recreational drug market in the mid-2000s and now represent a large class of new popular drugs of abuse. Initially considered as legal highs, their legal status is variable by country and is rapidly changing, with government institutions encouraging their control. Some cathinones (such as diethylpropion or pyrovalerone) have been used in a medical setting and bupropion is actually indicated for smoking cessation...

BACKGROUND: There is increasing focus on providing high quality care for people at the end of life, irrespective of disease or cause, and in all settings. In the last ten years the use of care pathways to aid those treating patients at the end of life has become common worldwide. The use of the Liverpool Care Pathway in the UK has been criticised. In England the LCP was the subject of an independent review, commissioned by a Health Minister. The Neuberger Review acknowledged that the LCP was based on the sound ethical principles that provide the basis of good quality care for patients and families when implemented properly...

Charles Bonnet syndrome is a condition characterized by visual hallucinations. These simple or complex visual hallucinations are more common in elderly individuals with impaired peripheral vision. The current report describes a case of transient Charles Bonnet syndrome appearing after the removal of a meningioma. The patient was a 61-year-old man who already had impaired visual acuity due to diabetic retinopathy. Brain MRI revealed a cystic tumor severely compressing the right occipital lobe. Starting on day 2 postoperatively, the patient was troubled by recurring visual hallucinations involving people, flowers, pictures, and familiar settings(the train and a coffee shop)...
