OBJECTIVE

To evaluate the long-term effects of annual course therapy with Cerebrolysin on cognitive functioning and the risk of transition to dementia in relatives of patients with Alzheimer’s disease (AD) with amnestic-type mild cognitive decline syndrome (aMCI) in comparison with the same group untreated relatives.

MATERIAL AND METHODS

The cohort included 88 first-degree relatives of BA patients with aMCI syndrome aged 50 to 82 years (mean age 65.0±9.9 years) of which 46 people received course therapy with Cerebrolysin and 42 people were not treated. Clinical, neuropsychological, statistical methods were used. Conducted annual course therapy with Cerebrolysin (a total of 3 courses of infusion therapy: for a course of 20 intravenous infusions of 20 ml of Cerebrolysin in 100 ml of isotonic saline) followed by a follow-up study after 3 months after the end of the therapeutic period. The dynamics of cognitive functioning in the therapeutic group was compared with the corresponding dynamics in the comparison group over the same period. The assessment was carried out on day 0, by the end of 1, 14, 27 and 30 months research.

RESULTS

In the therapeutic group, according to the CGI-I scale, by the end of the 3rd course of therapy, in 95.7% of cases, a pronounced or moderate improvement was achieved after each of the courses on all scales and tests. In this group, by the end of the therapeutic period, a significant improvement in the initial mean group scores was established. According to the all scales and tests, a significant improvement of the initial average group scores was found after each course of therapy (p<0.05). In the comparison group there was a significant deterioration (p<0.05) of the average group scores of most of the cognitive scales and test by the end of the observation. The annual conversion from aMCI to dementia due to probable AD was 9.5% only in the comparison group. The average group indicators of all scales and tests significantly worsened starting from the 14th month of observation in the comparison group.

CONCLUSION

The absence of cases of aMCI conversion to dementia in the treated patients for 2.5 years of observation can serve as confirmation of a disease-modifying effect in Cerebrolysin. These results indicate the need for more extensive clinical studies of the preventive effects of Cerebrolysin and to explore the possibility of including such therapy in drug prevention programs for AD in people at high risk for this disease.
