Depression: Almost everyone gets a little "depressed" at times in their lives, and a brief attack of the blues isn't necessarily anything to worry about. But if the symptoms of depression persist then it could be clinical depression, whether a severe or mild form of depression. Any persistant depressive symptoms need prompt medical investigation by a medical professional.
In some cases, the term "depression" will refer to full clinical depression. Other uses of the term may refer to the cluster of depressive disorders of which clinical depression is the most severe type. As mentioned above, the term "depression" may simply refer to depressive symptoms like sadness or down moods.
Diagnosis of depression is not always easy and an underlying cause is always possible. Depressive symptoms could be caused by an emotional upset (e.g. grief, divorce, job loss, etc), by drug abuse, or several other causes. Feeling "depressed" a few days after a major life crisis does not warrant a diagnosis of depression, and in fact taking antidepressants may be an inappropriate treatment in this case (e.g. they may avoid the healthy sequence of coping with grief or loss). However, over-diagnosis of depression and over-prescription of antidepressants in such situations is known to occur. Another possible over-diagnosis of depression is caused by the cycle of emotional symptoms that arise from premenstrual syndrome (PMS).
Depressive symptoms may also indicate some type of underlying physical medical disorder.
Various related depression-like physical symptoms (e.g. fatigue, lethargy, weakness, tiredness)
could be symptoms of an underlying condition
such as chronic fatigue syndrome, diabetes,
Parkinson's disease or several other possible underlying conditions
and alternative diagnoses.
Depression: Everyone gets the blues now and then. Itís part of life. But when there is little joy or pleasure after visiting with friends or after seeing a good movie, there may be a more serious problem. A depressed mood that stays around for a while, without let-up, can change the way a person thinks or feels. Doctors call this "clinical depression." 1
