However, hope is on the horizon thanks to functional neurosurgeons like Jocelyn Bloch. In Dr. Bloch's recent TEDx talk in Zurich, she explains how she and her colleagues discovered a particular kind of cells that may enable brains to help heal themselves.
Moreover, they performed this same experiment with a monkey that had suffered neurological damage, and had rehabilitated until he plateaued. Prior to reintroducing the cells, they had the monkey take a motor skills test. Then, they reintroduced the cells, and two months later, had the monkey take the same test. His progress was clearly and remarkably better.
Medical breakthroughs like this provide hope to those of us who care for sufferers of stroke or other brain injury.
