Bipolar disorder always includes both episodes of mania—high mood, grandiose thoughts and erratic behavior and episodes of depression.
Persons experiencing a manic episode feel terrifically elated, expansive, or irritated over the course of a week or longer and would also experience at least three of the following symptoms:
1) grandiose ideas and/or self-esteem in overdrive
2) a need for far less sleep than usual
3) an irrepressible need to speak
4) distractibility and racing thoughts
5) agitation or increased activity that may be directed toward a goal
6) an overpowering urge to seek pleasure that may be expressed in sexual sprees, overspending or a variety of schemes, often with disastrous consequences.
