Visuoperceptual deficits in delirium, such as hallucinations and delusions, are not due to the underlying cognitive impairment. Visual hallucinations during alcohol-withdrawal delirium are seen in persons with polymorphisms of genes coding for dopamine transporter and catechol-O-methyltransferase. Decreases in central nervous system gamma-aminobutyric acid levels are observed in patients with delirium resulting from benzodiazepine and alcohol withdrawal. Delirium has been associated with the disruption of cortisol and beta-endorphin circadian rhythms. This mechanism has been suggested as a possible explanation for delirium caused by exogenous glucocorticoids.
