The goals of this study were to assess the prevalence of delusions, hallucinations and minor \u2018psychotic\u2019 phenomena (visual illusions, feeling of presence and passage hallucinations) and to describe the characteristics of the latter in a non\u2010clinical older population.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>Three hundred and thirteen individuals aged 60\u2009years and older, without cognitive deficits (according to mini\u2010mental state examination scores) or patent psychotic disease, answered a structured questionnaire focusing on delusions, hallucinations and minor phenomena that they had experienced in the previous month.

These subjects did not differ from those without psychotic symptoms as regards their age, mini\u2010mental state examination scores or education. Minor phenomena were the most common (13%). Hallucinations, in any sensory modality, occurred in 9% of participants. No verbal auditory hallucinations or delusions were reported. The prevalence of minor phenomena increased with age and was associated with the use of psychoactive drugs.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>By extending the spectrum of psychotic symptoms to minor phenomena, we found that psychotic symptoms were common in a non\u2010clinical older population. Whether the increasing prevalence of minor phenomena with age is due to prodromal neurodegenerative disease or to other factors remains to be investigated.
