Sen. Kirk upgraded to fair condition, is talking

Illinois Sen. Mark Kirk is continuing to improve after a major stroke and has been upgraded to fair condition.

Northwestern Memorial Hospital neurosurgeon Richard Fessler says Kirk is alert, talking and responding well to questions.

The Chicago hospital released a statement Monday about Kirk's progress, a little more than a week after he suffered a stroke that's affected his left side.

Fessler says doctors are very pleased with Kirk's progress. Kirk is 52 and was in good health when he was stricken.

Doctors believe a clot developed from a tear in an artery in his neck and lodged in his brain. Doctors removed part of his skull to relieve pressure and allow the brain to swell.
