NEW YORK — One of the doctors treating Arizona U.S. Rep. Gabrielle Giffords says there was no change in her condition overnight.
Dr. Michael Lemole with the University of Arizona was interviewed Tuesday on NBC's "Today" show.
When asked about swelling in her brain on the third day, which is when it often reaches its peak, Lemole said a CAT scan early Tuesday showed no increase in swelling.
But he cautioned that it can sometimes take longer for swelling to peak.
Lemole said the fact that Giffords responds to commands indicates there's not a lot of pressure in the brain. That Giffords is able to "register that discomfort" is a positive sign, Lemole said.
Jared Loughner (LAWF'-nuhr) made his first court appearance Monday on federal charges. He's accused of Saturday's shooting spree that left six people dead and 14 wounded or injured.
