Visual Hallucinations

Research into visual hallucinations has accelerated over the last decade from around 350 publications per year in 2000 to over 500 in 2010. Increased recognition of the frequent occurrence of visual hallucinations in a number of common disorders, coupled with improvements in the measurement of phenomenology, and more sophisticated imaging techniques have allowed the development and initial testing of sophisticated models. However, key questions remain unanswered. Amongst these are: whether there is a satisfactory definition of hallucinations in a constructive visual system; whether there are one, two or several core varieties of hallucinations; what are the underlying brain mechanisms for hallucinations; and what, if anything, can be done to treat them when they lead to distress? Looking across research in several clinical areas suggests a tentative integrative model that allows the possibility of answering these questions, but much work remains to be done.
