[net.med] chemical depression?

I am interested in finding out about chemical depression.  It seems
(as reported by my mother) that numerous members of my family (mother,
uncle, cousin, grandmother, great-grandfather) have all been subject
to this thing called chemical depression.  Used to alleviate it is
the drug imapramine, an anti-depressant.

Is anyone out there currently, or in a prior life been, under the care
of a physician for this malady?  I am interested in whatever you can tell
me about it.  Were tests given?  What were your symptons?  Were you
subject to chronic fatigue?  How did you find out about it?  Was your
doctor knowledgeable about this condition?

Thanks for any and all replies.  Please mail them to :

Chemical depression is a misnomer--it refers to a theoretical subclassification
of major depression, an affective disorder requiring psychiatric treatment.
Basically, one category of patients with major depression have unusually
low levels of norepinephrine (NE) metabolites in their urine, and it's been
observed that these patients respond favorably to drugs that tend to increase
the availability of NE in the central nervous system (CNS).  On the other hand,
another category of patients with major depression have unusually low levels
of serotonin (5-HT) metabolites in their cerebro-spinal fluid, and this group
of patients responds favorably to drugs that tend to increase the availability
of 5-HT in the CNS.  And there's yet a third type of major depression in which
patients demonstrate an abnormal response to the hormone dexamethosone.

The antidepressant medications used to treat these illnesses fall into two
major categories:  tricyclic antidepressants (TCA) and monoamine oxidase
inhibitor antidepressants (MAO-I).  (Lithium carbonate is also used to
treat certain types of depression.) They are organized into various
subclasses depending on their relative specificities for neural membrane
receptor proteins.  These drugs can affect a large number of organ systems
within the body; serious side effects, even death can result if the
antidepressant medication is improperly chosen or prescribed (for example, a
person on MAO-I therapy could die from taking certain non-prescription cold
remedies).  Because of this, antidepressant therapy should only be administered
by a properly trained physician, preferably a psychiatrist--one who can do
a complete medical evaluation, who understands the various and many times
complex interactions between the body's organ systems, and who is
well-versed in the use of antidepressants.

There are a number of other types of depression which fit neither of the 
classes described above, and which respond only marginally if at all to
antidepressant medication.  These people generally respond quite well to one of
the various forms of psychotherapy currently practiced.

Hope this answers some of your questions.

I will restrain myself from unnecessarily maligning psychotherapy, and
will not try to discourage anyone suffering from depression from seeking
this form of help.  However, if the depression is severe, PLEASE PLEASE
PLEASE continue to seek MEDICAL help (from someone who is looking for
a PHYSICAL cause), no matter how many dozens of doctors you have to go
through, no matter how many tests you have to take, no matter how much
it costs.  Don't let ANYONE tell you that there is no physical cause,
just because THEY can't find one.
