Abstract:
In a single-stage observational study, the dynamics of indicators of prevalence and incidence of mental retardation in persons aged 60 years and older in the North-Western Federal district was studied. It was found that in the diagnostic structure of the prevalence of mental disorders of older people in the northwestern Federal district in 2018, the share of mental retardation is 2,9%. Among all patients with mental retardation, the proportion of elderly people in the regions of the northwestern Federal district ranges from 1,9 to 7,6%. From 2016 to 2018 in the northwestern Federal district, the increase in the prevalence of mental retardation of the elderly due to the cumulative effect was 9,6%, and the decrease in the incidence rate was 26,5%. Cases of primary diagnosis of mental retardation in older people may be due to migration factors and diagnostic errors. A more thorough assessment of the clinical picture of cognitive disorders in elderly patients and accurate follow-up of diagnostic criteria is required.
