Objective: To determine the efficacy and tolerability of tanakan in the treatment of memory and attention impairments in young patients. Material and methods: We studied 30 outpatients (24 women and 6 men, mean age 33,5±7,5 years) with headache, memory and attention impairments and decrease in mental working capacity. Treatment duration was 90 days. Patients received tanakan in dose 40 mg 3 times per day to restore cognitive function. The study design included 4 visits during which patients completed questionnaires and scales. Results: All patients reported positive changes in mood, memory, information learning and working capacity. Headaches of tension decreased by 50%, vertigo and noise in ears became less intense, autonomic disturbances practically disappeared. No effect on the frequency of migrainous attacks was found. Conclusion: Tanakan is effective and safe for symptomatic therapy of cognitive impairment in any age, including young patients.
