The swelling in Sen. Mark Kirk's brain has stabilized, doctors said Friday.
In a written statement to the media, Dr. Richard Fessler said Kirk is doing "quite well."
"He is alert, responding more rapidly to questions and the swelling in his brain has stabilized. While he remains in serious but stable condition, we are pleased with his continued progress,” said Fessler.
Kirk had an ischemic stroke last weekend, requiring emergency surgery to remove a 4-inch by 8-inch portion of his skull to allow for brain swelling. He had a second surgery Wednesday night to remove two small pieces of tissue "previously destroyed and rendered non-functional."
While there may be some permanent physical consequences, Fessler said he was optimistic about the senator's mental recovery.
