Catherine Zeta-Jones Back in Rehab with Bipolar Disorder: 5 Fast Facts You Need to Know

Catherine Zeta-Jones, 43, has checked into a rehab facility seeking treatment for her bipolar II disorder, reports CNN.

Here’s what you need to know…

1. She Checked in on Monday

TMZ reported that the Academy Award winner went to the facility on Monday. Zeta-Jones’ rep Cece Yorke told People Magazine:

Catherine has proactively checked into a health care facility, previously Catherine has said that she is committed to periodic care in order to manage her health in an optimum manner.

The celebrity magazine goes on to say:

Meanwhile, a source tells PEOPLE that Zeta-Jones was planning to return to treatment as a way for doctors to monitor her medication. “There was no big problem,” says a friend. “This was just a good time to do it. She is in between projects. This has always been part of the plan. She would manage her health. She is vigilant about it.”

Last week, Zeta-Jones and Michael Douglas were seen together at the Film Society of Lincoln Center tribute to Barbra Streisand as the recipient of the 40th anniversary Chaplin Award. A friend told People:

Catherine was on his [Michael’s] arm much of the time, she seemed really relaxed and happy. I saw her with a cocktail and she was socializing and enjoying the evening … Nothing seemed out of the ordinary, and they both seemed to be having a good time.

2. Her Condition Became Public in 2011

Just three months after her husband was declared “tumor-free”, a rep for Zeta-Jones told CNN that the star was checking into a facility, which was located in Connecticut:

After dealing with the stress of the past year, Catherine made the decision to check into 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.

After being discharged from the facility, a friend of Zeta-Jones told People Magazine:

She’s feeling much better-we’ve been laughing nonstop the last few weeks.

3. Her Disorder is a Less Severe Bipolar

According to the Mayo Clinic:

Bipolar II is less severe than bipolar I. You may have an elevated mood, irritability and some changes in your functioning, but generally you can carry on with your normal daily routine. Instead of full-blown mania, you have hypomania — a less severe form of mania. In bipolar II, periods of depression typically last longer than periods of hypomania.

Zeta-Jones is expected to complete at 30-day-program at the facility.

4. She Has Been Very Open About Her Condition

In a bit to remove the stigma associated with mental illness, Zeta-Jones has been very open about her fight against the condition. She said back in 2011:

This is a disorder that affects millions of people and I am one of them. If my revelation of having bipolar II has encouraged one person to seek help, then it is worth it. There is no need to suffer silently and there is no shame in seeking help.

5. This Has Been a Trying Time For Douglas and Zeta-Jones

Since Douglas was diagnosed with throat cancer in 2011, his son, Cameron, 34, was sentenced to five years in prison on heroin charges, and two weeks ago had his sentence increased to nine and half years after he was found with narcotics while in prison.

Then Douglas’ ex-wife, Diandra, sued the Basic Instinct star for half of his salary from Wall Street 2, citing that under the couple’s 1998 divorce settlement (at which she was awarded $45 million), she was entitled to 50% of any earnings Douglas made from characters he played while they were married. That case was thrown out by a New York City judge.

According to People reports, this put more pressure on Zeta-Jones:

“What’s the use of me crying around the house? That makes no sense to me or Michael,” Zeta-Jones told PEOPLE after the diagnosis. But privately, says her close friend, “she was scared.”
