Douglas` kids unaware about Zeta-Jones bipolar struggle

London: Actor Michael Douglas and Catherina Zeta-Jones are shielding their two young children from the actress` struggle with bipolar disorder because they have only just come to terms with their father`s recent cancer battle.

The ‘Wall Street’ actor underwent intensive treatment last summer after being diagnosed with stage four throat cancer, reports a website. He beat the disease in January but the Hollywood couple`s personal lives took another hit in April when the Chicago beauty was found to suffer from bipolar. Doctors diagnosed the condition after Zeta-Jones checked into a mental health clinic to treat depression, brought on by the stress of her husband`s battle. The stars, who explained all about Douglas` cancer fight to Dylan, 10, and Carys, eight, have chosen not to burden their kids with their mother`s issues so soon although Douglas worries they will find out through gossip at school. "No, they don`t know yet. We gotta give them a chance, they`re just getting over the other issues," said Douglas. IANS
