Research shows promise for
stopping progression of bipolar disorder
Changes in the brain that
are important indicators of bipolar disorder are not
prominent until young adulthood and are reduced in
persons taking mood-stabilizing medications, Yale School
of Medicine researchers report this month in Biological
Psychiatry.
The researchers used
magnetic resonance imaging to measure a part of the
brain that regulates emotions, the ventral prefrontal
cortex, that lies above the eyes. The changes in
persons with bipolar disorder were not prominent until
young adulthood, suggesting that the illness progresses
during the teenage years. Bipolar disorder is also known
as manic-depressive illness.
"The brain changes were
diminished in persons with bipolar disorder who were
taking mood-stabilizing medications," said Hilary
Blumberg, M.D., associate professor in the Department of
Psychiatry and director of Yale's Mood Disorders
Research Program. "This brings hope that it may someday
be possible to halt the progression of the disorder."
Blumberg added, "Research
to understand bipolar disorder in youths is especially
important because of their high risk for suicide."
Bipolar disorder is
characterized by episodes that range from emotional
highs, or manias, to emotional lows, or depressions.
Extreme manic highs can be associated with
over-spending, impulsiveness on the job or at school,
and risky behaviors, including sexual indiscretions that
can lead to loss of important relationships. Blumberg
said in depressive episodes individuals may "take to
bed" or, in severe cases, try to take their own lives.
