Depression is a serious illness, not a harmless part
of life. It is a complex disorder with a variety of
causes. It is never caused by just one thing. It may
be the result of a mix of factors, including
genetic, chemical, physical, and sociological. It is
also influenced by behavior patterns learned in the
family and by cognitive distortions.
Depression affects millions of people in this
country. It is always troubling, and for some people
it can be disabling. Depression is more than just
sadness or “the blues.” It can have an impact on
nearly every aspect of a person’s life. People who
suffer from depression may experience despair and
worthlessness, and this can have an enormous impact
on both personal and professional relationships. In
this newsletter, I will describe many of the factors
that may cause depression, and I will explore
strategies for preventing it.
Depression Is Pervasive
When a
person suffers from depression, it can affect every
part of his or her life, including one’s physical
body, one’s behavior, thought processes, mood,
ability to relate to others, and general lifestyle.
Symptoms of Depression
-
People who are diagnosed with clinical
depression have a combination of symptoms from
the following list:
-
Feelings of hopelessness, even when there is
reason to be hopeful
-
Fatigue or low energy
-
Much less interest or pleasure in most regular
activities
-
Low self-esteem
-
Feeling worthless
-
Excessive or inappropriate guilt
-
Lessened ability to think or concentrate
-
Indecisiveness
-
Thinking distorted thoughts; having an
unrealistic view of life
-
Weight loss or gain without dieting
-
Change in appetite
-
Change in sleeping patterns
-
Recurrent thoughts of death
-
Suicidal thoughts
-
A
specific plan for committing suicide
-
A
suicide attempt
-
Feelings of restlessness or being slowed down
When a
person is suffering from depression, these symptoms
cause significant distress or impairment in social,
occupational, or other important areas of
functioning. This means that the person’s family and
social relationships, as well as work life, are
impaired.
When a
person is suffering from depression, symptoms such
as these are not the result of a chronic
psychotic disorder, substance abuse, general medical
condition, or bereavement.
Grief,
Sadness, and Depression
Depression may include feelings of sadness, but it
is not the same as sadness. Depression lasts much
longer than sadness. While depression involves a
loss of self-esteem, grief, disappointment and
sadness do not. People who are depressed function
less productively. People who are sad or
disappointed continue to function.
Depression and Socioeconomic Factors
Depression does not seem to be related to ethnicity,
education, income, or marital status. It strikes
slightly more women than men. Some researchers
believe that depression strikes more often in women
who have a history of emotional and sexual abuse,
economic deprivation, or are dependent on others.
There
seems to be a genetic link; depression is more
common among parents, children, and siblings of
people who are diagnosed with depression. The
average age at the onset of a depressive episode is
the mid-20s. People born more recently are being
diagnosed at a younger age.
Physical Causes
Many
physicians believe that depression results from a
chemical imbalance in the brain. They often
prescribe antidepressant medication, and many people
find relief as a result. However, there is no
reliable test to identify such a chemical imbalance.
It is unknown whether life experiences cause mood
changes, which create changes in brain chemistry, or
whether it works in reverse.
Depression may be associated with physical events
such as other diseases, physical trauma, and
hormonal changes. A person who is depressed should
always have a physical examination as part of the
assessment process to determine the role of physical
causes.
Signs
That Professional Treatment Is Needed
If you
or someone you know is depressed and exhibits any of
the following signs, it is extremely important to
seek the assistance of a medical or mental health
professional.
-
Thinking about death or suicide. This is always
dangerous and you should see a professional
therapist immediately.
-
When symptoms of depression continue for a long
time, you may need professional help.
Acute responses to events are normal, but they
should not last beyond a reasonable time.
-
Your ability to function is impaired by your
depression. Seek help before your life situation
deteriorates to a serious level.
-
You have become so isolated that you have no one
with whom to check reality. Seek out someone to
share your thoughts and feelings with.
-
Depressive symptoms have become severe.
In my
next newsletter, I will discuss the treatment and
prevention of depression.
