Elation, Irritability Signs of Heightened Bipolar Disorder Risk

Elation and irritability may seem like relatively harmless swings of behavior, but a new study finds that in some individuals these may signal a high risk for development of bipolar disorder. In a report published online July 27 in the Journal of Affective Disorders, researchers at the University at Buffalo said that "elation and/or irritability, if accompanied by trouble concentrating, racing thoughts, or hyperactivity, may represent a prodrome of formal bipolar disorder that indicate close follow-up and cautious use of antidepressants."

The study population was 40,512 noninstitutionalized adults who took part in the National Epidemiologic Survey on Alcohol and Related Conditions and who in 2001-2002 (Wave 1) didn't meet criteria for lifetime mania or hypomania, but indicated the presence of elation and/or irritability. (The survey is sponsored by the National Institute on Alcohol Abuse and Alcoholism.) The researchers studied the same cohort in 2004-2005 and found that "The likelihood of developing a clear episode of mania or hypomania by Wave 2 was significantly increased in subjects with elation or only irritability at Wave 1, compared with subjects who did not endorse either. Endorsement of both symptoms at Wave 1 increased the likelihood of a new epsisode of mania or hypomania 4.6 times, which was significantly higher than for those with only elation or irritability."
