Not All Mood Swings are Bipolar Disorder

I sometimes hear people ask “one minute I feel down, the next minute I’m really happy, am I manic depressive?”

Bipolar disorder or manic depression is a mood disorder whereby a person has discreet episodes of depression or mania. The index episode is a term used to define the first episode. If a person’s index episode is depression, they may not be diagnosed with bipolar disorder until they have a manic episode. That is, this person may be diagnosed as having depression for years until they have a manic episode at which time their diagnosis will change to bipolar disorder. The person who has mania as their index episode will start with a diagnosis of bipolar disorder.

Everyone is different, but a typical course of the illness is such that a person may have 1-2 episodes of mania and/or depression in a year or every few years. Rapid cycling bipolar disorder is defined by having four or more episodes in a year.

So back to the question – people with bipolar disorder don’t switch between depression and mania within the course of a day. In fact, depression requires symptoms lasting two weeks to be considered a depressive episode. The situation of extreme moods that flip back and forth over the course of a day would be considered emotional lability or emotional volatility that may be present in a person with anxiety or a mood disorder (such as depression or bipolar disorder). But it can also be a part of someone’s personality. For example, people with histrionic personality traits can have dramatic or “over the top” responses that are intense reactions to life issues that are not necessarily a mental disorder that requires medication treatment.

Is it me or my illness?

Individuals with an disorder such as bipolar disorder can behave in ways that make them question whether their actions are part of their personality or part of their illness.  For example, two common symptoms with bipolar disorder are hypersexuality and hyperreligiousity.  However, defining what is “hyper” is not always an easy task.  It can be very difficult to tease out what is the person’s personality and what is being driven by the disinhibition that you can see with a manic episode.  It is often during a euthymic period (neither manic nor depressed) that a person can do some introspection and get a sense of who they are.  It can be sobering for some to realize their free spiritedness, high sex drive, etc. may have been their illness.  They are then left to figure out who they really are.

In a similar way, chronic irritability that may seem a part of someone’s personality could be persistent depression that once treated significantly improves.  In these cases, a person may feel relief to know they are capable of feeling happy or having a good outlook on life.

Am I Depressed or Just Not Manic?

Sometimes it’s difficult for bipolar patients to tell when they are in a depressed mode or if they have simply lost their manic high.  For many, mania can be a very destructive phase, but for some, mania or hypomania (milder form of mania) can feel very good and be a very productive time.  Sometimes this loss of the elation can make patients not want to take their mood stabilizer.  Some will say they experience the non-manic period as being flat or as if they are living a generic version of themselves.  They may then conclude they are “depressed” when in fact, they may not be depressed, they are just experiencing the middle ground.

Some patients may swing between cycles so often that they may not know how to recognize the middle ground.  This is why it is important for patients with bipolar disorder to stay in regular contact with their health care provider so they can have someone keeping an eye out for their mood states.  It’s not always as easy to recognize the beginning of a manic state as it is to recognize depression.  A person who is hypomanic may appear happy, upbeat and busy.  On the surface, that doesn’t seem so bad.  But it is usually the people close to them that recognize the more destructive behaviors such as functioning on little sleep, making impulsive decisions, etc.  So, although the hypomanic state may seem desireable and some even try to prolong the state (by avoiding medication), mania can spiral out of control.  Therefore it is important to keep a careful watch and welcome periods of non-mania and middle ground.
