Hallucinations: Etiology and clinical implications

Santosh Kumar et al. Ind Psychiatry J. 2009 Jul.

Abstract

The literature on hallucinations is reviewed, including history; theoretical background from physiological, biochemical and psychological points of view; classification; causation; presentation in different psychiatric and neurological disorders and in normal persons. The available evidence suggests that hallucinations result from a failure of the metacognitive skills involved in discriminating between self-generated and external sources of information. Management of hallucinations is briefly discussed.

Keywords: Etiology; Hallucinations; Psychopathology.
