Serene Branson talks about her on-air complex migraine on 'The Talk'

Serene Branson, the television reporter who became tongue-tied during her live report from the Grammys for CBS News 2, is opening up about the terrifying experience for the first time with "The Talk's" Julie Chen on the show's Feb. 18 episode.

"I didn't feel well before that live shot. I had a headache," Branson says. "I was having some blurry vision and when I went to open my mouth, obviously you heard, the words were not coming out."

Branson has watched the footage and tells Chen what it was like to see it: "Seeing [the footage] - it's obviously very disconcerting [and] scary because I know what was going on in my head at the time. I was terrified."

So what was Branson trying to report? "I knew I wanted to say. I wanted to say that Lady Antebelluem had swept the Grammys that night, but the words were not there for me."

Branson also tells Chen what she was trying to say in the report: "I knew I wanted to say that Lady Antebellum had swept the Grammys that night," Branson recalls. "But the words were not there fr me."

Initially, people thought Branson had suffered a possibly stroke, but According to Dr. Neil Martin, chief of neurosurgery at the UCLA Medical center, what viewers saw on the frightening video was actually a symptom of a "complex migraine."
