Teresa Heinz Kerry suffered a grand mal seizure, a medical source who treated her told NBC News on Monday, a day after the wife of Secretary of State John Kerry was rushed to the hospital. Her condition was upgraded Monday to fair from critical, a spokesman for her husband told NBC News, following what NBC News' medical source called "an electrical storm in the brain." The 74-year-old environmental activist and heiress to the Heinz ketchup fortune had been flown to Massachusetts General Hospital in critical but stable condition with her husband; she had earlier been rushed by ambulance Sunday from the couple's Nantucket, Mass., home to a local hospital. Heinz Kerry is a breast cancer survivor and the mother of three adult sons from her marriage to Pennsylvania's late Sen. John Heinz, who died in a plane crash in 1991. Sec. Kerry has been in Nantucket since returning from the Middle East on Wednesday.
