| Annotation | Limited data are available on the incidence of psychotic symptoms in older people. A 1971-72 population sample of 392 residents of Goteborg, Sweden born in 1901-1902 was assessed from age 70-90, with psychiatric examination, medical record reviews and from age 85, also with key-informant interviews. Individuals developing dementia were excluded. The cumulative incidence of first-onset psychotic symptoms was 4.8% (8% including key informant reports in the total sample) and 19.8% in those who survived to age 85. 64% of those with first-onset hallucinations later developed dementia, compared to 30% of those with delusions and 25% of those without psychotic symptoms. One fifth of non-demented older people who survive up to age 85 develops first-onset psychotic symptoms. Hallucinations predict dementia, but most older individuals with first-onset psychotic symptoms do not develop dementia. (RH). |
