At the present time information about course and outcomes of psychosis oflate age, are virtually absent.The aim of the study was to establish the laws of the dynamics and prognosis of hallucinatory psychoses oflate age according to clinical follow-up study.Material. The material included 60 patients at the age of 60 and older with hallucinatory psychoses, developed inlate age at first time.Methods. During the study methods were used as follows: clinical follow-up, clinical-psychopathological, neuroimaging (MRI/ CT), psychometric (MMSE, Hachinski ischemic scale, Neuropsychiatric Questionnaire, NPI).Results. Clinical and follow-up examination of a group of patients, manifested in old age at the first time, showed a high incidence of adverse outcome. Prognostically unfavorable were patients with a true visual hallucinosis, hallucinosis with a long history, and patients with moderate or severe dementia on admission to hospital. Psychotic relapse pattern of psychosis with repeated admission generally is matched the characteristics of hallucinosis on admission. Among patients with recurrent hallucinatory psychosis prevailed cases of visual hallucinosis. Half of the patients re-admitted to the hospital for two years, was found the progression of dementia, and as a consequence a significant simplification of the productive psychotic symptoms.Conclusion. Hallucinatory psychoses of late age prognostically unfavorable, have a high frequency of recurrence of the disease, which depends not only on the psychopathological picture of psychosis, but also on the course of the disease and the presence of cognitive impairment.
