[Cognitive functions in late-onset psychosis].

The review discusses cognitive functions in late-onset schizophrenia and very late-onset schizophrenia-like psychosis compared to cognition in normal aging, early-onset schizophrenia, and neurodegenerative diseases. The problem of the dynamics of the state of the cognitive functions in patients with late-onset schizophrenic psychoses is highlighted, and prospects for further research are discussed. Patients with late-onset schizophrenic psychosis are characterized by more pronounced cognitive deficits compared to normal aging, but less severe than cognitive changes observed in early-onset schizophrenia. Late-onset schizophrenia may be a heterogeneous condition in terms of cognitive dysfunction.
