What
is Depression
Depression
is classically defined as a psychiatric mood disorder characterized
by feelings of extreme sadness or guilt, an inability to concentrate,
helplessness, hopelessness, and thoughts of death that can lead
to some degree of impairment—whether mild, moderate, or severe.
It can appear as a result of life changes such as divorce, loss
of a job, or death of a loved one. Or depression may also come about
gradually for no apparent reason at all.
Statistically, depression
is the second most common medical condition observed in general
medical practice today—behind hypertension alone. An estimated
16% of adults in Western countries suffer from major depression
at some point in their lives, and of these, only 25% receive adequate
treatment.
Like most chronic
conditions and their symptoms, there is not one single cause for
depression. Rather, there are several different factors which can
contribute to and cause depression. When depression is not a by-product
of external events, it is called endogenous, meaning “originating
from within.” This kind of depression is believed to be fundamentally
due to biochemical abnormalities specifically an altered balance
of the neurotransmitters serotonin, norepinephrine, and dopamine.

Diagnosis
and Pharmaceutical Interventions
Diagnosis of depression
is usually done with a counselor, therapist, a psychologist or some
other medical practitioner. A through psychological evaluation should
be performed before the diagnosis is given. Most people with depression
respond to a combination of therapies, which includes supplementation
and ‘talk’ therapy with a counselor, therapist or psychologist.
Laboratory testing may be done to evaluate neurotransmitter levels,
for example to check for levels of serotonin. Most often these tests
are done when an individual is being monitored with therapies that
specifically act on the neurotransmitter pathways, such as serotonin
reuptake inhibitors (SSRI’s) or 5-Hydroxy-Tryptophan (5-HTP).
Medications for depression
Conventional medicines can be prescribed by medical doctors or psychiatrists
to treat depression.
Following
is a list of common conventional medicines that may be used for
depression.
Serotonin
Selective Reuptake Inhibitors (SSRIs)
The most commonly
prescribed antidepressants. These include: Citalopram (Celapram),
Fluoxetine (Prozac), Paroxetine (Aropax), Sertraline (Zoloft). These
medications increase the neurotransmitter serotonin in the brain,
which elevates mood and energy. These medications at times can increase
the level of serotonin so much that a serotonin syndrome presents,
especially when used in conjuction with other medications that act
in a similar fashion, or with the use of other mind altering drugs.
The symptoms of the serotonin syndrome include tremor, changes in
mental affect and cognition. In addt6ion SSRI’s can cause
irritation and bleeding of the stomach and gastrointestinal tract,
and cause lower libido as a sexual side effect.
The second
most common class of medications prescribed is tricylic antidepressants.
These include: Amitriptyline (Amitrip), Clomipramine (Clopress),
and Imipramine (Tofranil). Monoamine Oxidase Inhibitors (MAOIs)
are rarely prescribed. They include Tranylcypromine (Parnate). Some
other types of medication that may be used are Bupropion (Zyban),
and Venlafaxine (Efexor).
A host of potential
side-effects (or symptoms of withdrawal) accompany the use of many
if not all of these drugs. Some of the most serious of these are:
anxiety, asthenia – loss of bodily strength, blurred vision,
constipation , decreased ability to think clearly, development of
drug dependency, development or worsening of suicidal tendencies,
dizziness, dry mouth, insomnia , loss of libido and other sexual
side effects, nausea , nervousness, rash , somnolence – sleepiness
or a lack of energy and activity, and sustained increase in blood
pressure (hypertension).

Lifestyle
and Dietary Modifications
Exercise increases
the body’s production of endorphins—chemical substances
that can relieve depression. This makes exercise one of the most
powerful antidepressants available. The best exercise is aerobic
activities such as walking, swimming, bicycling or dance; as well
as strength training such as weight lifting.
Alcohol abuse or
dependence on alcohol is associated with depression, especially
if used with other drugs or if the individual has a history of antisocial
behavior. Reducing alcohol dependency or abuse can reduce the feeling
of depression, improve memory and well being.
Getting enough sleep
is very important for mental health, as many people with a problem
with depression may also have insomnia. One way to improve sleep
is to go to bed at the same time every night, only use your bed
for sleeping (or being intimate with your partner but not reading
or working in bed), and doing breathing exercises or relaxation
therapy before bed.
Food sensitivities
may play a part in depression, as when chronic exposure to a food
or compound that the body regards as foreign can induce an altered,
lethargic state that may be confused for depression, or may even
cause depression. Identification of food sensitivities and avoiding
them can significantly help in a persons well being and mood.
The type of dietary fat may also play a role in depression, as the
balance of fats in the diet can have an effect on brain function.
The lack of omega 3 fatty acids (from fish) has been associated
with increased levels of depression. People who eat diets high in
omega-3 fatty acids from fish have a lower incidence of depression
and suicide.
Certain nutrient deficiencies are directly related to depression.
Some examples of these are iron and iron deficiency anemia, vitamin
B12 deficiency (which can also cause pernicious anemia), folic acid
and other B vitamins,
Some medications are known to create depression for instance oral
contraceptives can deplete Vitamin B6, a nutrient needed for normal
mental functioning. Other substances are oral steroids, alcohol
and some mind altering drugs such as marijuana.

Nutritional
Factors Shown to be Beneficial
Omega 3
Fatty acids
Omega 3 fatty acids from fish oils, specifically DHA, has a beneficial
effect on the functioning of the nervous system.
Dose: 3-6 grams of fish oil a day, or 2 grams
of DHA a day
5-HTP
5- hydroxytryptophan is a precursor the neurotransmitter serotonin,
and can act in a similar fashon as some of the antidepressant medication
but with fewer side effects.
Dose: 50-300 mg three times a day
St John’s
wort (Hypericum perforatum)
St John’s wort has been studied for the treatment of disease
in over 20 studies and with over 1,500 people. It is best used for
mild to moderate depression. St. John’s wort should not be
used with other antidepressant medications that have an activity
on the serotonin pathway. St. John’s wort may also reduce
levels of other prescription medications including birth control
pills and some antimicrobial medications.
Dose: 500-1000 mg twice or three times a day
Vitamin
B6
Vitamin B6 or pyridoxine, acts as a coenzyme in energy7 producing
pathways, and is also involved in the bodys conversion of amino
acids to serotonin, one of the main neurotransmitters involved in
mood.
Dose: 50-200 mg a day
Vitamin
B12
Vitamin B12 or cobalamin is required for a healthy nervous system
and can help in the treatment of sleep disorders, which many people
with depression may suffer from .
Dose: 1000-5000 mcg
Inositol
Inositol is member of the B vitamin complex and work as a messenger
in the central nervous system. It is useful in the treatment of
depression and anxiety.
Dose: 1-5 grams a day
Ginkgo biloba
The herb Ginkgo improves the health of the brain by increasing blood
flow to the head. It is also an antioxidant.
Dose: 120 – 240 mg of standardized extract
a day
Phosphatidylserine
Phosphatidylserine, a natural substance derived from serine, affects
the levels of neurotransmitters in the brain related to mood. It
is found in high amounts in brain tissue.
Dose: 200–500 mg per day
Theanine
Theanine is an amino acid that is found in the tea plant. It increase
neurotransmitter activity and has been shown to help the brain achieve
a state of relaxation
Dose: 200 mg two to three times a day
