Actress Catherine Zeta-Jones has entered a US mental health clinic for treatment of her bipolar condition.
Her publicist Sarah Fuller said Zeta-Jones "is committed to periodic care in order to manage her health in an optimum manner."
Two years ago, the 43-year-old Oscar winner and wife of actor Michael Douglas, checked into a similar facility for treatment of her condition, known as Bipolar II. The disorder is characterized by mood swings and depressive episodes and is commonly treated with medication and psychotherapy.
Zeta-Jones has been one of the busiest talents in show business of late, appearing in films such as "Rock of Ages," ''Playing for Keeps," ''Broken City" and "Side Effects."
Her most recent treatment was first reported by the TMZ website.
