What is Depression?
 Depression is a serious medical illness; it's not
something that you have made up in your head. It's more than just feeling "down
in the dumps" or "blue" for a few days. It's feeling "down" and "low" and
"hopeless" for weeks at a time.
There are several forms of depressive disorders. The
most common are major depressive disorder and dysthymic disorder.
Major depressive disorder, also called major
depression, is characterized by a combination of symptoms that interfere with a
person's ability to work, sleep, study, eat, and enjoy once-pleasurable
activities. Major depression is disabling and prevents a person from functioning
normally. An episode of major depression may occur only once in a person's
lifetime, but more often, it recurs throughout a person's life.
Dysthymic disorder, also called dysthymia, is
characterized by long-term (two years or longer) but less severe symptoms that
may not disable a person but can prevent one from functioning normally or
feeling well. People with dysthymia may also experience one or more episodes of
major depression during their lifetimes.
Some forms of depressive disorder exhibit slightly
different characteristics than those described above, or they may develop under
unique circumstances. However, not all scientists agree on how to characterize
and define these forms of depression. They include:
Psychotic depression, which occurs when a severe
depressive illness is accompanied by some form of psychosis, such as a break
with reality, hallucinations, and delusions.
Postpartum depression, which is diagnosed if
a new mother develops a major depressive episode within one month after
delivery. It is estimated that 10 to 15 percent of women experience postpartum
depression after giving birth.
Seasonal affective disorder (SAD), which is
characterized by the onset of a depressive illness during the winter months,
when there is less natural sunlight. The depression generally lifts during
spring and summer. SAD may be effectively treated with light therapy, but nearly
half of those with SAD do not respond to light therapy alone. Antidepressant
medication and psychotherapy can reduce SAD symptoms, either alone or in
combination with light therapy.
Bipolar disorder, also called manic-depressive
illness, is not as common as major depression or dysthymia. Bipolar disorder is
characterized by cycling mood changes-from extreme highs (e.g., mania) to
extreme lows (e.g., depression)

Treatment
Depression, even the most severe cases, is a highly
treatable disorder. As with many illnesses, the earlier that treatment can
begin, the more effective it is and the greater the likelihood that recurrence
can be prevented.
The first step to getting appropriate treatment is
to visit a doctor. Certain medications, and some medical conditions such as
viruses or a thyroid disorder, can cause the same symptoms as depression. A
doctor can rule out these possibilities by conducting a physical examination,
interview and lab tests. If the doctor can eliminate a medical condition as a
cause, he or she should conduct a psychological evaluation or refer the patient
to a mental health professional.
The doctor or mental health professional will
conduct a complete diagnostic evaluation. He or she should discuss any family
history of depression, and get a complete history of symptoms, e.g., when they
started, how long they have lasted, their severity, and whether they have
occurred before and if so, how they were treated. He or she should also ask if
the patient is using alcohol or drugs, and whether the patient is thinking about
death or suicide.
Once diagnosed, a person with depression can be
treated with a number of methods. The most common treatments are medication and
psychotherapy.
