Is Kelly Osbourne suffering from epilepsy?

Kelly Osbourne could possibly be suffering from epilepsy, it has been reported.

According to sources who told TMZ, Kelly Osbourne’s seizure, which caused her to collapse on the set of her show on Thursday, may be related to the brain condition.

Kelly Osbourne, 28, is reportedly staying in hospital for a few more days as doctors run tests to determine her medical state.

Medical practitioners at the hospital are thought to believe that Kelly Osbourne may be epileptic.

The source, who is said to be close to Kelly Osbourne, told the website that doctors believe her seizure may have been an “isolated incident” and are now attempting to figure out how to prevent another episode from happening.

For the meantime, Kelly Osbourne is said to be on anti-seizure medication until her diagnosis is confirmed.
