After a traumatic brain injury, it sometimes happens that the brain can repair itself, building new brain cells to replace damaged ones. But the repair doesn't happen quickly enough to allow recovery from degenerative conditions like motor neuron disease (also known as Lou Gehrig's disease or ALS). Siddharthan Chandran walks through some new techniques using special stem cells that could allow the damaged brain to rebuild faster.

Siddharthan Chandran: Can the damaged brain repair itself?

Can the damaged brain repair itself?

35 million people live with brain diseases, costing $700 billion globally. The urgency for effective treatments is clear.

Yamanaka's breakthrough in 2006, converting adult cells to pluripotent stem cells, ignites hope for regenerative neurology.

Brain repairs itself post-damage, yet not swiftly enough to counteract diseases like ALS, spotlighting stem cell potential.
