Treatment for
depression in conventional
medicine is determined by the
severity and type of depression. Most cases of depression will be
treated on an outpatient basis. For
mild depression, psychotherapy is the
preferred method of treatment. This
therapy can be with completed with
visitations to a counselor,
psychologist, or psychiatrist. For
moderate to severe
depression, psychotherapy is
used in conjunction with
specific medications.
SSRI's, or selective
serotonin re-uptake inhibitors, MAOI's (monoamine oxidase
inhibitors), and HCA's (heterocyclic
antidepressants) are the most common
medicines used in patients with
moderate to severe depression. Other
medication that may be prescribed
include 5-HT
antagonists and catecholaminergics. [10] Because of the
activity these drugs
have on specific neurotransmitters in the
brain, one is advised not quit
the drug at once; as this may lead
to a more serious rebound depression. Any changes in a treatment protocol
should be under the supervision of a
licensed physician.
There are some
alternative treatments that have
been effective treating mild to
moderate depression. Due to
the pronounced effects of these
treatments on
the levels of neurotransmitters in
the brain, it is recommended that
individuals consult a physician before
beginning any alternative treatment
program. Many of the common
drugs used to treat depression
interact with alternative
treatments, and may eventually cause
‘serotonin syndrome'.
Serotonin syndrome results from an
excess of serotonin in the brain,
and can cause high blood pressure,
increased heart rate, anxiety, etc.

Supplements helpful for Depression
Treatment |
St. John's Wort (Hypericum
perforatum)
St. John's Wort has
been extensively studied as a
treatment for depression. It is useful alone for mild to
moderate depression, and can be a
valuable addition to drug therapy
for severe depression. The exact
mechanism of its action is still not
completely understood. St. John's Wort appears to increase the
levels of neurotransmitters in the
brain, including serotonin, norepinephrine,
and dopamine. [11]
One study compared
the effects of Hypericum extract
to imipramine, an HCA. It
was found
that Hypericum yielded
therapeutically equivalent
results, and far fewer side effects
than imipramine. Patients also
tolerated St. John's Wort better
than HCA. [12]
Another study, comparing
Hypericum extract to the SSRI,
sertraline, indicated that St.
John's Wort was as effective for mild to moderate
depression as sertraline. [13] In another study, comparing
Hypericum to
placebo in mild to moderate
depression, patients had
significant benefit. A significant
number of patients had a greater
than 50% improvement in just 6
weeks. [14]
Tryptophan
Tryptophan is the
amino acid precursor to serotonin,
a neurotransmitter in the brain.
Supplementation with tryptophan
can increase the production of
serotonin. Tryptophan is often
depleted in patients with
depression. In various studies, tryptophan has been effective
in treating mild to moderate
depression. In one particular study, tryptophan was found to increase
the benefit of Fluoxetine, a SSRI,
without causing serotonin
syndrome. [15]
Folic Acid
Folic acid is a
vitamin necessary for proper
functioning of the central nervous
system. The level of folic acid in
the serum or blood of patients
with depression has proven to
affect treatment. One study found
that low folic acid levels were
associated with a decreased
treatment response to SSRI's and
HCA's in patients with major
depression. Folic Acid supplementation
increased the effectiveness of
these commonly prescribed drugs. [16]
Another study found that deficient
levels of folic acid were related
to the degree of depressive disorder. [17]
DHEA
DHEA is a steroid
hormone precursor produced by the
body. It has been studied as a
treatment for major depression. Fluctuating hormone levels are
thought to contribute to
depressive episodes. The exact
mechanism for DHEA and it
influence upon depression
is not fully understood, though is
has some effect on neural cell
receptors in animal models. Supplementation
of DHEA for 6 weeks
resulted in significant
antidepressant effects and a
decreased score on the Hamilton
depression scale in patients with
major depression. [18]
