Changes in structural network topology correlate with severity of hallucinatory behavior in Parkinson’s disease [PDF]

Network Neuroscience, 2019
Inefficient integration between bottom-up visual input and higher order visual processing regions is implicated in visual hallucinations in Parkinson’s disease (PD). Here, we investigated white matter contributions to this perceptual imbalance hypothesis.

EEG changes associated with hallucinations caused by Charles Bonnet Syndrome [PDF]

Frontiers in Neurology
Charles Bonnet syndrome (CBS) is characterised by the presence of visual hallucinations following visual loss in many patients. The neuropathophysiology of CBS is poorly understood.

Association between voriconazole-induced visual hallucination and dopamine in an analysis of the food and drug administration (FDA) adverse event reporting system database [PDF]

Scientific Reports
Voriconazole is a second-generation azole used to treat serious fungal infections. Visual hallucinations constitute a representative adverse event caused by voriconazole. However, its mechanism of action remains unclear. In patients with schizophrenia or

Temporal assessment of behavior in Parkinson’s visual hallucinations via a multidimensional analysis strategy [PDF]

Signal Transduction and Targeted Therapy
Visual hallucination (VH) is a common nonmotor symptom of Parkinson’s disease (PD). However, the lack of reliable animal models and quantitative assessment tools poses significant challenges for mechanism and intervention research in this area.

Event-Related Potentials in Parkinson’s Disease Patients with Visual Hallucination [PDF]

Parkinson's Disease, 2016
Using neuropsychological investigation and visual event-related potentials (ERPs), we aimed to compare the ERPs and cognitive function of nondemented Parkinson’s disease (PD) patients with and without visual hallucinations (VHs) and of control subjects ...

Validation of the Arabic version of the Launay-Slade Hallucination Scale Extended: A population-based online survey in Saudi-Arabia. [PDF]

PLoS ONE
Hallucinations occur when individuals perceive sensory events as real despite the absence of external stimuli. The Launay-Slade Hallucination Scale Extended Version (LSHS-E) is a validated measure for assessing hallucination proneness and has been ...

Visual Hallucinations

Journal of the Royal College of Physicians of London, 1997
Hallucinations may be defined as perceptions that occur in the absence of a corresponding stimulus. They can involve any of the five senses, hence visual, auditory, tactile, gustatory and olfactory hallucinations. By contrast, illusions depend upon a misinterpretation of an external stimulus.
