00:00:00,000 --> 00:00:06,667
Cerebrolysin is a mixture of small peptides and amino acids derived from porcine brain tissue.

2
00:00:06,667 --> 00:00:10,542
It is not one precisely defined signaling peptide.

3
00:00:10,542 --> 00:00:14,792
Researchers have investigated effects on cell survival and signaling.

4
00:00:14,792 --> 00:00:21,042
For example, an early experiment used rat microglial and astrocyte cultures, not patients recovering

00:00:21,042 --> 00:00:24,542
brain function.

6
00:00:24,542 --> 00:00:28,042
Human outcomes need separate evidence.

7
00:00:28,042 --> 00:00:35,125
A 2023 Cochrane review found no convincing mortality benefit in acute ischemic stroke and raised concern

8
00:00:35,125 --> 00:00:38,625
about nonfatal serious adverse events.

9
00:00:38,625 --> 00:00:43,708
The manufacturer states Cerebrolysin is not approved in the United States.

10
00:00:43,708 --> 00:00:50,792
A neurotrophic research rationale should not be presented as proof of brain regeneration or a general

cognitive boost.
