Result: The authors present a case of a woman who at the age of 64, started to suffer delusions and hallucinations and who was diagnosed with schizophreniaparanoid type, after the authors had made the differential diagnosis with delirium, other somatic conditions, dementia, delusional disorder, and affective disorders. Discussion and conclusion: The historical validity of late onset schizophrenia, its differential diagnosis, and clinical features are discussed.
