Cindy, Casey and George Anthony
Casey Anthony may have suffered from a medical condition that contributed to the death of her 2-year-old daughter Caylee, her parents have said.

In an exclusive interview with Dr Phil, due to air this Monday, Casey’s parents, George and Cindy Anthony, claim their daughter may have suffered from a gran mal seizure while her toddler was dying, a source told Fox News Channel.

A grand mal seizure — also known as a tonic-clonic seizure — features a loss of consciousness and violent muscle contractions according to the Mayo Clinic.

Cindy Anthony reportedly told Dr Phil that Casey’s former fiancée told police during a 2008 interview that he had previously called 911 after she suffered a seizure in 2005.

The source told FOX that Casey suffered two more seizures, one when she was on bond in 2008 and another will she was imprisoned between 2008 and 2001.

The source also said Casey is "deeply upset that her parents continue to seek the spotlight,"

Dr Phil said the interview is "intending to focus on promoting processes to educate the public about, and advocate for, grandparents' rights."

Casey (25) was acquitted on July 5 of the murder of her daughter but found guilty of misleading investigators.
