Bipolar Disorder Exacts Twice Depression's Toll In Workplace
Bipolar disorder costs twice as much in lost productivity as major depressive disorder, a study funded by the National Institutes of Health's (NIH) National Institute of Mental Health (NIMH) has found. Each U.S. worker with bipolar disorder averaged 65.5 lost workdays in a year, compared to 27.2 for major depression. Even though major depression is more than six times as prevalent, bipolar disorder costs the U.S. workplace nearly half as much ?a disproportionately high $14.1 billion annually. Researchers traced the higher toll mostly to bipolar disorder's more severe depressive episodes rather than to its agitated manic periods. The study by Drs. Ronald Kessler, Philip Wang, Harvard University, and colleagues, is among two on mood disorders in the workplace published in the September 2006 issue of the American Journal of Psychiatry.
