Acclaimed Puerto Rican writer Esmeralda Santiago's life revolves around words. But six years ago, a stroke robbed her of the ability to speak and read. With fierce determination, she taught herself to read again, the way a child does with simple picture books, starting small and building from there. Her story is featured in the latest issue of Neurology Now. She talks about the challenges stroke patients face, and the path she took to find her words again.
