[3][4] Although it is under preliminary study for its potential to treat various brain diseases, it is used as a therapy in dozens of countries in Eurasia.
[4] No clear benefit in the treatment of acute stroke has been found, and an increased rate of spontaneous adverse effects requiring hospitalization is reported.
[5] A 2023 review indicated that cerebrolysin or cerebrolysin-like peptide mixtures from cattle brain likely provide no benefit for preventing all-cause death in acute ischemic stroke, and that higher quality studies are needed.
[5][8] Early studies have suggested potential use of cerebrolysin with a wide variety of neurodegenerative disorders, including traumatic brain injury,[9][10] schizophrenia,[11] multiple sclerosis,[12] cerebral palsy[13] and spinal cord injury[14][15] although research is still preliminary.
[1] In trials studying the use of cerebrolysin after acute stroke, there was no increased risk of "serious adverse events" requiring hospitalization.
