Bipolar disorder – originally known as manic depression – is a mental health condition characterized by extreme mood swings. These extreme mood swings are further broken down to include the emotional highs and lows regarded as mania or hypomania and depression.
There are a few different types of bipolar disorder, with the two most prevalent being Bipolar I and Bipolar II. Bipolar I disorder is defined by mania while bipolar II is defined by hypomania. Both include periods of elevated feelings such as euphoria, high energy, or irritability. They can affect sleep, daily activities, judgment, behavior, thought patterns, and energy levels.
The primary difference is that mania (Bipolar I) is much more severe and can lead to episodes of psychosis. It’s also longer lasting while hypomania (Bipolar II) is less severe and only lasts a few days, while it also always is associated with severe depression.
It should be noted, however, that Bipolar II isn’t a “milder form” of Bipolar I, but rahter a separate diagnosis altogether. While the manic episodes of Bipolar I can be severe and incredibly dangerous, those with Bipolar II disorder can become more depressed and for longer periods.
Generally speaking, bipolar disorder can occur at any age even though it’s usually diagnosed in the teenage years or early 20s. The symptoms can vary from individual to individual and also typically vary over time.
