Features of dissomnia and cognitive impairments in chronic cerebral ischemia due to diabetes mellitus type 2

Introduction. Currently, diabetes mellitus occupies a leading position in terms of prevalence, disability, mortality and it is a medical and social problem. Microvascular and macrovascular diabetic complications negatively affect the quality and duration of sleep with detrimental effects on metabolism and weight regulation. The cognitive sphere is more impaired in type 2 diabetes mellitus in the form of a decrease in the speed of reaction to external stimuli and the ability to concentrate for a long time, so thinking becomes slower, and clinically significant cognitive impairments leads to work and social maladaptation and a decrease in adequate glycemic control. Aim of the study: to study the nature of diagnosed cognitive impairments and variants of dissomnias in chronic cerebral ischemia and to evaluate the features of identified dissomnias in the development of early dementia in type 2 diabetes mellitus. Object and methods. During the period from 2017 to 2023, 207 patients with chronic cerebral ischemia and neurological deficits of varying severity were examined. All patients underwent a comprehensive clinical and neurological examination using specialized scales to study the cognitive sphere and sleep level, laboratory and instrumental methods of examination. The study applied non-inclusion, inclusion and exclusion criteria and selected 147 patients with chronic cerebral ischemia and type 2 diabetes mellitus. The data has been processed statistically.
