UPDATE: Clinton making progress

Secretary of State Hillary Clinton is still in the hospital for treatment of a blood clot.

She's on blood thinners to break up the clot located in her head.

Doctors found the clot Sunday on a brain scan.

Experts say she's lucky she didn't suffer a stroke or any neurological damage.

"Clot in a transverse venous sinus that goes along the side of your brain is a potentially life threatening complication," said Dr. Richard Besser, ABC News Chief Medical Editor. "The goal here is to try to dissolve that clot, so it goes away or at least doesn't get larger."

Clinton, 65, caught a stomach virus last month. Then, days later, she fainted and suffered a concussion.

Doctors say she's making excellent progress and will be released once they've worked out the proper dose of medication.
