WISC anchor Sarah Carlson, who recently underwent brain surgery to combat the recurrence of epileptic seizures, suffered what a appeared to be a mild seizure on-air yesterday evening.

At the beginning of WISC‘s 6 p.m. newscast on Tuesday, Carlson was delivering the news that Wisconsin would join other states in a lawsuit against President Obama’s health care overhaul.  Towards the end of the report, the veteran anchor begins to slur her words and for a moment her speech becomes unintelligible.

Miraculously, though, Carlson is able to finish.  When the camera cuts to Carlson’s co-anchor Susan Siman, a moment of surprise registers on her face before she plows ahead with the newscast’s next segment. Carlson left the newscast following the incident and Siman finished it solo.

“She’s okay,” Colin Benedict, WISC’s news director, assured the Wisconsin State Journal following the on-air episode.  Benedict says that he expects Carlson to continue anchoring the CBS-affiliate’s evening newscasts.

Carlson momentarily stepped away from TV in 2009 following a serious seizure that she suffered on-air while working for Madison NBC-affiliate WMTV.  She joined WISC in December after having surgery to remove a non-cancerous tumor from her brain.  At the time, Carlson reported that her life was nearly seizure free.
