Specifically in conjunction with "Bipolar II Disorder," it appears to be the interchanging mood and consequent behavior from the so called "Hypomanic" situation to the "Depressive" condition. In other words - as amateurs in behavioral science understand by reading the pertinent entries in AMA DMN-IV 4th ed.:
"Hypomanic Disorder" is said to have and display the following more noticeable composite mood-behavioral: 1. "Inflated self-esteem or grandiosity." 2. "Decreased need of sleep." 3. "More talkative than usual." 4. "Flight of ideas." 5. "Psychomotor agitation." Etc. Etc.
"Depressive Disorder" on the other hand means the following combined signal mood-pattern: 1. "Dejection. Gloominess. Cheerlessness." 2. "Inadequacy. Worthlessness. Low self-esteem." 3. "Brooding. Worrisome. Self-blaming." 4. "Negativistic. Pessimistic." 5. "Remorseful."
One thing appears clear and certain: Bipolar II Disorder in general has reference to "clinically significant distress in social, occupational or other areas of functioning." This means and implies that the said Disorder is anything but a personality asset in relational inter-action in a family, in a community and in society as a whole. Considering that every human agent has a social nature and yet prove to be socially impaired - this is a big behavioral liability in getting married, in doing business, in holding offices and the like.
And unless otherwise established, it seems that Bipolar II Disorder is not really susceptible of complete and permanent cure - although it may have temporal, occasional or periodic remissions usually in terms of calming drug intake. This is sad - to say the least.
