The association of the of late‐life onset psychotic symptoms with incident cognitive impairment in a cognitively normal sample.

Previous research suggests around 5–10% of cognitively normal older people report some degree of psychotic experiences as measured in the Mild Behavioral Impairment framework. Such late‐onset symptoms potentially confer a relatively high risk for neurodegenerative disease so there is a need for studies examining their clinical correlates prior to dementia onset. We compared the relationship between psychotic symptoms and progression to cognitive impairment in a large community‐dwelling sample of adults over 50.
