Semax And Stroke

My grandmother was recently a light stroke which resulted in the impairment of memory, intelligence, etc. She took immediately course of Cogitum, Piracetam, Cavintonum, Mexiprime + Mexidol injections, but the results are not very happy. Advise whether it is appropriate now will take a course of Semax 0,1% + Noben?

Maybe you should start with nasal drops Semax 1%?
But in the case of a stroke is more likely to take a course of Cerebrolysin injection.
