TL;DR: A consistent set of factors are associated with visual hallucinations in Parkinson's disease, and those of visual hallucinations carried out in other settings suggest a common physiological substrate for visual hallucinations but with cognitive factors playing an as yet unspecified role.

TL;DR: Considering the implicit nature of representational momentum and its modifiability, the findings suggest that higher-order semantic information can act on secondary visual cortex to alter perception without explicit awareness.

TL;DR: The study revealed that Parkinson's patients with hallucinations appear to have intact visual imagery processes and spatial perception, however, there were impairments in object perception and recognition memory, and poor recollection of the encoding episode in comparison to both non-hallucinating Parkinson's Patients and healthy controls.

TL;DR: Generally, the texts of the students with dyslexia were poorer than age controls but not poorer than the spelling-skill controls, however, there were no major differences in "higher order" skills such as ideas and organization with the chronological age controls.

TL;DR: In this article, a systematic literature search using standard electronic databases of published surveys and case-control studies was undertaken to summarise the factors most often associated with visual hallucination in Parkinson's disease and carry out a clinical comparison of ambulant patients with and without visual hallucinations.
