Good, Good.

Sounds like there's a good chance Johnson's going to be okay:

The attending physician of the Capitol, Adm. John F. Eisold, who examined Mr. Johnson before he was sent to the hospital Wednesday, said the bleeding was caused by a rare tangling of the blood vessels in the brain, known as a congenital arteriovenous malformation, that physicians say often goes undetected. The operation successfully drained the blood and stabilized the problem, Admiral Eisold said in a statement released by Mr. Johnson’s office.

“He has been appropriately responsive to both word and touch,” Admiral Eisold said. “No further surgical intervention has been required.”

Doctors who specialize in the condition said that in the overwhelming majority of cases the bleeding does not cause long-term damage, particularly for someone who showed the symptoms Mr. Johnson did. But they said the outcome might not be known for weeks or months.

Specialists in the condition, while emphasizing that they did not know the specifics of Mr. Johnson’s case, varied in their assessment of the likely damage. Dr. Mohr said that what had been reported — that Mr. Johnson could still hold the phone and walk — “suggests to me that the brain was not totally destroyed.” [That's, um... encouraging?] Very likely, he said, doctors discovered blood that had leaked in the ventricles, which could be removed “with very little damage to the adjacent brain.”

“He was able to get up and walk around and report to a local hospital,” Dr. Mohr said. “These are the things that could make for a favorable result.”

Huzzah!
