Hallucinations in the general population across the adult li
Community studies have found a relatively high prevalence of hallucinations, which are associated with a range of (psychotic and non-psychotic) mental disorders, as well as with suicidal ideation and behavior.

Researchers aimed to explore the prevalence and psychopathologic significance of hallucinations across the adult lifespan.

Using 1993, 2000, 2007, and 2014 cross-sectional Adult Psychiatric Morbidity Survey series (N = 33 637), investigators calculated the prevalence of past-year hallucinations in the general population ages 16 to ≥90 years. They used logistic regression to examine the relationship between hallucinations and a range of mental disorders, suicidal ideation, and suicide attempts.

- The prevalence of past-year hallucinations varied across the adult lifespan, from a high of 7% in individuals aged 16–19 years, to a low of 3% in individuals aged ≥70 years.

- In all age groups, hallucinations were associated with increased risk for mental disorders, suicidal ideation, and suicide attempts, but there was also evidence of significant age-related variation.

- In particular, hallucinations in older adults were less likely to be associated with a co-occurring mental disorder, suicidal ideation, or suicide attempt compared with early adulthood and middle age.

The findings highlight important life-course developmental features of hallucinations from early adulthood to old age.
