He was in his early 40s when one morning he suddenly lost the ability to speak. He could not move the right side of his body. The married father of two young children made it to the hospital a few hours later and was diagnosed with a stroke involving the left side of his brain. Despite our best efforts to help him, he was no longer able to work and required around-the-clock care. He lost so much in a matter of seconds. I cared for that young man over 20 years ago during my residency training. We made the correct diagnosis, but the arsenal in our stroke toolkit for reversing his stroke was limited back then.
