Hallucinations are sometimes encountered in the course of alcohol withdrawal; however, both the factors predisposing to alcohol withdrawal hallucinations (AWH) and the implications of AWH with respect to the mechanisms of hallucinations remain unclear. To clarify these issues, we used data from the National Epidemiologic Survey on Alcohol and Related Conditions (NESARC) to investigate the demographic correlates, alcohol-use clinical patterns, and psychiatric comorbidities in two groups: drinkers with and without a history of AWH. We estimated the odds ratios for studied factors and used logistic regression analyses to compare the two groups. We found that over 2% of drinkers reported AWH (758 of a sample of 34,533 subjects). Alcohol tolerance and withdrawal seizures were highly associated with AWH, and exposure to alcohol during brain development was associated with a 10-fold increase in AWH compared to exposure during adulthood. African Americans, Native Americans, and unmarried subjects, as well as subjects with lower levels of education and lower levels of income were more likely to experience AWH. Furthermore, those with a history of AWH had higher odds ratios for most psychiatric illnesses than those without such history—yet of anxiety disorders, only panic was associated with AWH. These associations suggest that higher levels of education and of standard of living could protect against AWH; while social isolation, hypervigilance, exposure to alcohol during brain development, and long and severe exposure to alcohol could predispose to AWH.
