Secretary of State Hillary Clinton is being treated for a blood clot near her brain.

She's being given blood thinners to dissolve the clot, which is located in the vein in the space between her brain and the skull behind her right ear.

Doctors say they are confident will make a full recovery and was in good spirits. They added that she did not suffer a stroke or neurological damage.

The clot formed after she suffered a concussion during a fainting spell in early December. She had been ill with a stomach virus that left her severely dehydrated when she fainted.

Clinton's complication "certainly isn't the most common thing to happen after a concussion," explained Dr. Larry Goldstein, a neurologist who is director of Duke University's stroke center. He is not involved in Clinton's care.

Goldstein said it is one of the few types of blood clots in the skull or head that are treated with blood thinners.
