[Cognitive impairment in patients with obesity and impaired carbohydrate metabolism (dysglycemia)].

Obesity is a chronic disease, heterogeneous in etiology and clinical manifestations, progressing with a natural course, characterized by excessive deposition of fat mass in the body. This pathological condition has taken on the scale of a global epidemic in recent years, which continues to progress steadily, currently affecting more than 2 billion people worldwide. Due to its heterogeneity, obesity has a negative impact on the work of almost all organs and systems of the body, contributing to the emergence of new concomitant diseases and pathological conditions that significantly worsen the quality of life of these patients. Thus, a close relationship between type 2 diabetes mellitus and cognitive impairment has long been known, as well as with a number of other somatic diseases: coronary heart disease, atherosclerosis, non-alcoholic fatty liver disease, dyslipidemia, malignant neoplasms and other associated pathological conditions against the background of overweight and obesity.Currently, the problem of the relationship of cognitive impairment in patients with overweight or changes in the glycemic profile is very relevant, due to the high prevalence and insufficient study of this issue.
