Bipolar II: Catherine Zeta-Jones treated for milder form of disorder
"After dealing with the stress of the past year," read the statement, "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."
But what is Bipolar II?
According to Web MD, the condition is similar to Bipolar Disorder -- moods cycle between highs and lows, but the highs "never reach full on mania." A person suffering from Bipolar II might experience a "hypomanic episode":
During a hypomanic episode, elevated mood can manifest itself as either euphoria (feeling "high") or as irritability. Symptoms include flying suddenly from one idea to the next; rapid, "pressured," and loud speech; increased energy and hyperactivity with a decreased need for sleep.
"People experiencing hypomanic episodes are often quite pleasant to be around. They can often seem like the 'life of the party' -- making jokes, taking an intense interest in other people and activities, and infecting others with their positive mood."
But, warns WebMD, hypomanic episodes will be followed by depressive episodes similar to regular clinical depression, "with depressed mood, loss of pleasure, low energy and activity, feelings of guilt or worthlessness, and thoughts of suicide."
Treatments include mood stabilizing medications.
