BACKGROUND The aetiology of visual hallucinations is poorly understood in dementia with Lewy bodies. Pathological alterations in visual cortical excitability may be one contributory mechanism. AIMS To determine visual cortical excitability in people with dementia with Lewy bodies compared with aged-matched controls and also the relationship between visual cortical excitability and visual hall...

background: septic intracranial venous thrombosis is a rare vascular disease of the brain with no specific sign or symptom. while urgent treatment will result in complete recovery, delays may cause permanent complications or even death. case report: the patient was a 23-year-old woman who had suffered visual loss, hallucination, and confusion two weeks after undergoing submandibular abscess rem...

People with schizophrenia who hallucinate show impairments in reality monitoring (the ability to distinguish internally generated information from information obtained from external sources) compared to non-hallucinating patients and healthy individuals. While this may be explained at least in part by an increased externalizing bias, it remains unclear whether this impairment is specific to rea...

Recently, it has been proposed that exaggerated top-down processing may generate spontaneous perceptual output, and that this may constitute a cognitive predisposition toward hallucinations. In this experiment, we investigated whether hallucination proneness would be associated with increased auditory-verbal perceptual expectations, and at which processing level this occurs. From 351 undergradu...

When one visually hallucinates, the object of one’s hallucination is not before eyes. On standard view, that because does exist, and so anywhere. Many different defenses view are on offer; each has problems. This article defends there always an hallucination—a physical object, sometimes with spatiotemporally scattered parts.

This paper develops a statistical inference approach, Bayesian Tensor Inference, for style transformation between photo images and sketch images of human faces. Motivated by the rationale that image appearance is determined by two cooperative factors: image content and image style, we first model the interaction between these factors through learning a patch-based tensor model. Second, by intro...

We herein report a 65-year-old man demonstrating dementia with Lewy bodies who first presented with Bálint's syndrome. Two years later, a mild cognitive impairment was noted. From three years after onset, he developed progressive parkinsonism, visual hallucination, and autonomic dysfunction, in line with the deterioration of the cognitive function. Single photon emission computed tomography wit...
