Dynamics of cognitive disorders in patients with type 2 diabetes mellitus under effect of metabolic therapy

The aim of this study was to investigate the efficiency of metabolic therapy in correction of cognitive impairment in patients with type 2 diabetes. We undertook the analysis of results of the treatment of cognitive dysfunction in 80 patients with a diagnosis of type 2 diabetes. All patients received basic hypoglycemic therapy. 32 patients (study group) received in addition to the basal glucose lowering therapy daily intravenous infusion of 10 mlcytoflavindiluted in 200 ml of a 0.9% sodium chloride solution for 10 days, followed by 2 tablets b.i.d. for 25 days.The group of comparison consisted of 29 patients given in addition to the basal glucose-lowering therapy daily intravenous infusion of 24 ml (600 mg) thioctacid diluted in 200 mL of a 0.9% sodium chloride solution for 10 days. Thereafter, they received 1 tablet of thioctacid BV once daily for 30 days. The control group consisted of 19 patients who received basic hypoglycemic therapy without additional metabolic therapy.Inclusion of cytoflavin in the combined treatment of patients with type 2 diabetes ensured a more effective correction of cognitive impairment. There was a statistically significant improvement in optical-spatial activities (p = 0.001), attention (p = 0.001), abstract thinking (p = 0.046), and memory (p<0.001) compared to those in other groups, according to the MOS test. Positive dynamics was expressed as the improvement of the optical-spatial activities by 9,8 ± 10,3%, attention by 13,5 ± 11,8%, abstract thinking by 7,0 ± 8,9%, and memory by 23.0 ± 14 6%. The study of variations of the serum level of brain neurotrophic factor (BDNF) over time during the treatment with metabolic preparations reveal edits statistically significant increase (p = 0.002) in the patients treated with cytoflavin compared with comparison (p = 0.139) and control (p = 0.078) groups. These results suggest the influence of cytoflavin on the processes of neuroplasticity under conditions of hyperglycemia, improvement of cerebral microcirculation and cerebroprotective action of this medication.
