LOS ANGELES: A spokeswoman for Catherine Zeta-Jones says the actress has ”proactively” checked into a mental health facility for treatment of her bipolar condition.

Publicist Sarah Fuller said in an email to The Associated Press late Monday that 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 checked into a similar facility for a brief stay for treatment of her condition, known as Bipolar II. The disorder is characterised 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 such films as ”Rock of Ages”, ”Playing for Keeps”, ”Broken City” and ”Side Effects”.
