Bipolar disorder, also known as manic-depressive illness, is a brain disorder that causes unusual shifts in mood, energy, activity levels, and the ability to carry out day-to-day tasks. Symptoms of bipolar disorder are severe. They are different from the normal ups and downs that everyone goes through from time to time. Bipolar disorder symptoms can result in damaged relationships, poor job or school performance, and even suicide. But bipolar disorder can be treated, and people with this illness can lead full and productive lives.
Bipolar mania, hypomania, and depression are SYMPTOMS OF BIPOLAR disorder. The dramatic mood episodes of bipolar disorder do not follow a set pattern -- depression does not always follow mania. A person may experience the same mood state several times -- for weeks, months, even years at a time -- before suddenly having the opposite mood. Also, the severity of mood phases can differ from person to person.
Hypomania is a less severe form of mania. Hypomania is a mood that many don't perceive as a problem. It actually may feel pretty good. You have a greater sense of well-being and productivity. However, for someone with BIPOLAR DISORDER, hypomania can evolve into mania -- or can switch into serious depression.
