One of the heavy progressive vascular complications of type 2 diabetes is a central nervous system, manifesting cognitive dysfunction due to metabolic changes. Goal. Defining the role of brain-derived neurotrophic factor (BDNF) in the diagnosis of cognitive dysfunction in patients with type 2 diabetes. Materials and methods. The study involved 83 patients with type 2 diabetes at the age of 40 - 70 years. Complex examination included clinical and laboratory examination, neuropsychological testing. To screen for cognitive impairment used the Montreal Cognitive Assessment Scale (MOS test). To identify early markers of cognitive impairment was determined the level of brain-derived neurotrophic factor (BDNF). Results. The study found a negative correlation between the level of BDNF and the HbA1c (r = - 0,494, p = 0.01), fasting glucose (r = - 0,499, p = 0.01), and a positive relationship between the level of BDNF and cognitive function in patients with type 2 diabetes. Conclusion. In patients with type 2 diabetes revealed cognitive dysfunction in the form of reduced memory, attention, optical-dimensional activity that correlated with chronic hyperglycemia. The role of brain-derived neurotrophic factor (BDNF) in the complex diagnosis of cognitive dysfunction in patients with type 2 diabetes. With an increase in HbA1c in patients with type 2 diabetes reduces the level of BDNF in the blood plasma, and a decline in cognitive function. Recommended use of BDNF as an
additional marker of cognitive dysfunction in patients with type 2 diabetes.
