A 74-year-old man reported experiencing hallucinations of a dog standing on his right side, following a recent episode of infective endocarditis. There was no history of reduced conscious level, psychosis or substance misuse. Neurological examination revealed an isolated right inferior quadrantopia, and the hallucinations were visible only in the area of the visual defect. A computed tomography...

The simulation of visual hallucinations has multiple applications. For example in helping diagnosis, in helping patients to express themselves and reduce their sense of isolation, for medical education, and in legal proceedings for damages due to eye / brain injuries. We present a new approach to hallucination simulation, which was developed initially for a performance but proved to have potent...

BACKGROUND Charles Bonnet syndrome is a rare disorder characterized by complex and recurrent visual hallucinations in elderly patients with visual pathway pathologic defects. To date, to our knowledge, it has not been described in patients undergoing surgical resection for occipital lobe epilepsy due to cortical dysplasia. OBJECTIVE To describe a patient who experienced complex visual halluci...

Charles Bonnet syndrome (CBS) commonly occurs in older adults with visual impairments, particularly those with age-related macular degeneration. It is characterized by complex visual hallucinations in individuals without mental disorders. The authors explore diagnostic criteria, demographic characteristics, clinical features, theories of pathogenesis, and management options for people who are d...

Visual hallucinations are a well recognized unwanted effect of treatment with levodopa. Although many individual cases have been reported, there has only been one review previously published about this finding, and this did not discriminate age groups. We present five cases and briefly review the literature. It is important to enquire specifically about visual hallucinations in patients on levo...

Complex visual hallucinations are a well-known feature of electrical stimulation or epileptic discharge in the temporal lobe. It has been proposed that these visual hallucinations result from an electrical interference with the ventral visual processing stream in the lateral temporal lobe and the memory system in medial temporal structures, which explains their frequent visual and mnestic featu...

Trazodone, a second-generation atypical antidepressant, is increasingly being used off-label, in the treatment of insomnia. Although generally well tolerated, trazodone treatment can be associated with some complications. We describe a case of a 60-year-old man who received trazodone for primary insomnia. He returned, to the emergency department, two days later with distressing visual hallucina...

BACKGROUND Evidence suggests that auditory hallucinations may result from abnormally enhanced auditory sensitivity. AIMS To investigate whether there is an auditory processing bias in healthy individuals who are prone to experiencing auditory hallucinations. METHOD Two hundred healthy volunteers performed a temporal order judgement task in which they determined whether an auditory or a visu...
