Introduction. In chronic cerebrovascular diseases (CVD), neuroprotective medications, the effectiveness of which requires further study, are widely used. The effectiveness of Cytoflavinum in patients with chronic CVD was evaluated.Material and methods. The data of 60 patients (35 women and 25 men) with chronic CVD were analyzed. 30 patients, included in the main group (mean age 61 ± 5.87 years old), in addition to basic therapy (antihypertensive, antithrombotic drugs, statins), received Cytoflavinum according to the following scheme: 1 time a day in the morning intravenously 10.0 ml for 10 days, then 2 tablets 2 times a day for 30 days. 30 patients in the comparison group (mean age 59.8 ± 8.7 years old) received only basic therapy. An analysis of patient complaints, neurological status was carried out. Mini Mental State Examination (MMSE), the Montreal Cognitive Assessment (MoCA), Hospital Anxiety and Depression Scale (HADS) were used.Results. In the group of patients taking Cytoflavinum, there was a decrease in the frequency and intensity of headache, dizziness, an increase in MMSE score from 26.32 ± 0.86 to 28.05 ± 1.36 (p ≤ 0.05), in MoCA score from 25.35 ± 0.96 to 27.88 ± 1.13 (p ≤ 0.05), decrease in anxiety score from 8.82 ± 1.31 to 5.2 ± 2.82 (p ≤ 0.05) and decrease in HADS depression score from 8.31 ± 1.85 to 4.6 ± 3.15 (p ≤ 0.05).Conclusion. The inclusion of Cytoflavinum in the treatment regimen for patients with chronic CVD helps to reduce the frequency and intensity of headaches and dizziness, improve cognitive functions, and reduce the level of anxiety and depression.
