THE AMERICAN TELEVISION reporter who was rushed to hospital after fears she had suffered a stroke live on air has returned to work to tell her experience.

Serene Branson is understood to have suffered from a migraine that mimics symptoms of a stroke.

She lapsed into gibberish live  on a CBS’ local station KCBS as she was reporting on the Grammy Awards.

She has told how she was terrified, scared and confused when it happened and said watching herself back on the clip was “troubling”.

She gave an interview to CBS’s The Early Show on Friday morning in which she said:

I knew something wasn’t right as soon as I opened my mouth. I hadn’t been feeling well a little bit before the live shot.

I had a headache, my vision was very blurry. I knew something wasn’t right, but I just thought I was tired.

So when I opened my mouth, I thought, ‘This is more than just being tired. Something is terribly wrong.’

I wanted to say, ‘Lady Antebellum swept the Grammys.’ And I could think of the words, but I could not get them coming out properly.

A doctor told Associated Press that about 20 to 30 per cent of people who suffer from migraines experience sensations before or during the attack.

He said that Branson would have felt numbness on the right side of her face that would have affected her speech.
