(21 December 1980 - June 15, 2014) (1 child)
Kasem has been married to actress Jean Kasem since 1980. They have one child, Liberty Jean Kasem.
In October 2013, Kerri Kasem said that her father was suffering from Parkinson's disease; a few months later, she said that Casey Kasem was diagnosed with Lewy body dementia, which is often difficult to differentiate from Parkinson's. Due to his condition, he was no longer able to speak.
On October 1, 2013, his three oldest children and his brother protested in front of Kasem's home, claiming that Jean Kasem had prevented contact with their father for 3 months. On October 7, 2013, Julie Kasem and her husband Dr. Jamil Aboulhosn filed a conservatorship petition to place Kasem under their care. However, the court denied their petition.
On May 12, 2014, Kerri Kasem was granted conservatorship over Jean Kasem's objection. The court also ordered an investigation into Casey Kasem's whereabouts, after Jean Kasem's attorney told the court Casey Kasem was "no longer in the United States". Casey Kasem was found soon after in Washington state.
On June 6, 2014, Kasem was in critical but stable condition at a hospital in Washington state, receiving antibiotics for bedsores and treatment for high blood pressure. It was revealed that he has been bedridden for some time.
Judge Daniel S. Murphy ruled that Kasem had to be hydrated, fed, and medicated as a court appointed lawyer reported on his health status. Jean Kasem claimed that he had been given no food, water or medication the previous weekend. Kerri Kasem's lawyer stated that she had him removed from artificial food and water on the orders of a doctor, and in accordance with a document Kasem signed in 2007 requesting he not be held up artificially on life support. Murphy reversed his order the following Monday, after it became known that Kasem's body was no longer responding to the artificial nutrition, allowing the family to place Kasem on "end-of-life" measures over the objections of Jean Kasem.
