Catherine Zeta-Jones's representative has revealed that the star sought treatment for bipolar disorder at a health facility.

Zeta Jones, 41, made a decision to check into a "mental health facility" for a brief stay, said her publicist.

Bipolar disorder, otherwise known as manic-depressive disorder, brings about unusual changes in mood and energy that can result in manic episodes - an overly excitable state - or depressive episodes - a state of heightened sadness.

A representative for the actress released a statement saying: "After dealing with the stress of the past year, Catherine made the decision to check in to a mental health facility for a brief stay to treat her Bipolar II disorder."

"She's feeling great and looking forward to starting work this week on her two upcoming films."

It is unclear when Zeta Jones, who is from Swansea, was diagnosed with bipolar disorder or where she received treatment.
