When extreme changes in mood, sleep, energy and behavior occur for prolonged periods of time, there may be a disruption of hormonal balance producing this emotional change. These extremely polar highs and lows influence the way people think and interact with family, friends, coworkers, and even themselves. Part of the difficulty for family is not understanding how to interact with their loved one with bipolar disorder or personality disorder. The perception of oneself, others and their environment interfere with regular functioning in life. Group therapy, family counseling and more can help.
