Understanding Depression
People don't recognize depression as an illness. They think the physical symptoms they experience - fatigue,
change of appetite and sleep problems - are signs of another kind of illness. Still others think these
problems are "all in their head" and that nothing's really the matter with them.
But depression is a brain disorder that affects your whole body -- your behavior and mood, the way you think
and the way your body feels. Although scientists do not know the exact mechanism that triggers depressive
illness, some pieces of the puzzle include:
<> Genetic factors Some depressions may be attributable to genetic factors. Some studies have found a
link with depression in biological families that was not found in families with adopted children.
<> Chemical imbalances, Substance abuses Additional research suggests that people suffering
depressions have imbalances in the natural substances that allow brain cells to communicate with one another
<> Life stresses Any kind of life change, good or bad, can sometimes trigger depression.
<> A serious illness Depression may be caused by certain medications, such
as
pain relievers for arthritis, cholesterol-lowering drugs
