Sixty patients with chronic brain ischemia (discirculatory encephalopathy, I and II stages) were enrolled in the study. Patients of the first group (n=30) were treated with cytoflavin and patients of the second group (n=30) received piracetam prescribed first as injections and then in pills. The treatment duration was 35 days. Standard neurological examination and psychometric assessment of patients and dopplerography of cerebral vessels were carried out. Cytoflavin was shown to have a positive effect on the neurological status. It decreases asthenic, cephalgia and vestibulo-cerebellar syndromes as well as neurological and emotional disturbances reducing the symptoms of depression and anxiety and improving cognitive functions and memory as well as quality of life of patients. The changes were significant compared to those in the group of patients treated with piracetam.
