A YouTube video by Paul Savage MD titled "Brain Regeneration: How to Grow New Brain Cells!" discussing neuroregeneration in brain injury medicine. The speaker overturns an older teaching (neurons lost are gone forever), states adult neurogenesis occurs in regions like the hippocampus, identifies BDNF (brain-derived neurotrophic factor) as important for growing new neurons, notes cardiovascular exercise raises BDNF, and briefly mentions hyperbaric oxygen therapy as additional evidence for neuroregeneration.

So we do the same thing in brain injury medicine as well. When I was in training, we were taught that once you lose neurons, they never come back. They're gone forever. They're super specialized. That has since been proven wrong. Okay, so now we know that you can actually grow new neurons in parts of your brain, like the hippocampus, which is the memory part of the brain. And one of the ways to do that is to. There's a substance in our bodies called bdnf. Brain derived neurotropic factor. And one of the best ways to get BDNF is regular cardiovascular exercise. So, you know, so there's. So to your question about regeneration, there's also some evidence for neuroregeneration with modalities like hyperbaric oxygen therapy.
