From a LitHub online article by Chip Walter, 69:
And what if older neurons were replaced wholesale with new stem cells? They might scramble different sectors of the brain by destroying the new connections between the originals. Fiddle with those, and who knew what mayhem might follow? Memories, learning, and other cerebral functions that the brain had grown accustomed to might simply vanish. On the other hand, in the case of a disease like Alzheimer’s, maybe new memories would be better than no memories at all.
Robert Hariri’s views on human health began to take an unusual turn a little more than 25 years ago, when he was working as a neurosurgeon and trauma doctor at the New York Hospital-Cornell Medical Center. Day after day, he watched patients come into the emergency room with severe brain injuries, and it was a painful thing to witness.
He never forgot the case of a woman who had arrived after a senseless automobile accident. She was young, and the injury was bad. Every time he spoke with the family, the big questions they asked were: “How will she be? Will she come back? Could she be a mother to her children again?” It broke his heart.

This week on Prognosis, we look at one startup that’s trying to redesign care for some of the most vulnerable patients, taking into account the complex realities of their lives.
