Psychotic symptoms are common among both demented and nondemented older adults and demand resources from the social and health care systems. There are different etiologies of these symptoms, and different possible underlying medical contributing illnessess, concomitant medications, dementia, delirium, and psychiatric comorbidities should be identified before a specific antipsychotic treatment is considered.
Key words: psychosis, hallucinations, delusions, paranoid older adults.
