Cerebrolysin

Cerebrolysin is a mixture of peptides purified from pig brains, including (and not limited to) brain-derived neurotrophic factor (BDNF), glial cell line-derived neurotrophic factor (GDNF), nerve growth factor (NGF), and ciliary neurotrophic factor (CNTF), that is approved in many European and Asian countries for treating stroke. It is also sold via the internet as a nootropic. Cerebrolysin helps reduce the number of apoptotic cells after ischemic lesions. It also helps decrease the deposition of beta-amyloid in models of dementia, and has been found to enhance cognitive function in people with vascular dementia.
