Excerpt

Delusions, hallucinations, and other psychotic symptoms can accompany a number of conditions in late life. These symptoms may be more common than previously thought; Swedish investigators found that the prevalence of any psychotic symptom in a population-based sample of 95-year-old individuals without dementia was 7.1%, with 6.7% experiencing hallucinations, 10.4% having delusions, and 0.6% experiencing paranoid ideation (Ostling and Skoog 2002; Ostling et al. 2007), and in a sample of 85-year-old people, the prevalence of psychotic symptoms was 10.1%, with 6.9% experiencing hallucinations, 5.5% having delusions, and 6.9% experiencing paranoid ideation (Ostling and Skoog 2002).
