Authors studied the efficacy of cytoflavin in the correction of cognitive impairment in patients with type 2 diabetes mellitus and the drug influence on the level of brain-derived neurotrophic factor (BDNF) in blood serum. The results of treatment and examination of 60 patients with type 2 diabetes diagnosis have been analyzed. The majority (49-81.6%) of patients initially exhibited light (35-71.4%) and moderate (14-28.6%) cognitive impairments. All patients received standard treatment with oral antidiabetic drugs: metformin monotherapy (26 patients or 43.3%) and combined therapy (metformin + gliclazide, 34 patients or 56.6%). In addition, 30 patients (main group) received a complex metabolic drug cytoflavin daily intravenously (10 mL in 200 mL of 0.9% sodium chloride) for 10 days with transition to the tablet form in a dose of 2 tablets (with 0.6 succinic acid, 0.1 riboxin, 0:05 nicotinamide, 0.01 riboflavin) two times a day for 25 days. The control group (n = 30) consisted of patients who received only basic hypoglycemic therapy. The inclusion of cytoflavin in the scheme of complex treatment of patients with type 2 diabetes ensured a more effective correction of cognitive impairments as compared to the group receiving basic therapy. This is confirmed by the results of neuropsychological testing (MoCA test) and improved optical and spatial activity, attention, abstract thinking, and memory on the average by 14.2% compared to the value before treatment (p < 0.01) in patients of standard treatment group. Patients in the control group showed positive dynamics of same parameters amounted on the average to 7.9%. The study of BDNF in the blood serum showed a significant increase in this index over time in patients who have received cytoflavin (from 1475.13 + 421.26 pg/ml to 1839.44 + 494.78 pg/mL, p < 0.01) in contrast to the control group (1625.41 + 322.53 pg/mL to 1592.04 + 373.47 pg/mL) and revealed positive correlation between the MoCA test and BDNF level in the blood serum for optico-spatial activity (r = 0.589, p < 0.01), naming (animals) (r = 0.346, p < 0.01), attention (r = 0.401, p < 0.01), memory (r=0.595, p< 0.01) and total rating in the test (r = 0.708, p < 0.01). In addition, a negative correlation was revealed between the level of carbohydrate metabolism (HbA1c) and BDNF levels in the blood serum (r = -0.494, p < 0.01) in both groups.
