Read the following information to help you decide whether you might
have
depression. Depression is more than a temporary
feeling of sadness or lack of energy—it is a medical condition that requires
treatment. If you think you may be depressed, see your health professional for
diagnosis and treatment right away. Untreated depression may get worse.
This information is provided to help you decide whether you have
symptoms of depression, but it is not a substitute for a professional
evaluation. Only your health professional can accurately diagnose
depression.
You are diagnosed with major depression if you have at least five of
the symptoms listed below for at least 2 weeks in a row, and one of the
symptoms must be depressed mood or loss of interest. If you have fewer than
five symptoms, you may still be depressed and need treatment.1
- Depressed mood most of the day, almost every
day. You may feel sad or empty, or others might have noticed that you appear
sad or tearful.
- A significant loss of pleasure in either all or
almost all of your daily activities
- A significant weight gain or
weight loss or a decrease or increase in your appetite
- Difficulty
either falling or staying asleep or sleeping too much
- Noticeable
changes in how you walk and talk—you may appear restless or move very
slowly
- Extreme fatigue or loss of energy
- Feeling
worthless or having inappropriate guilt
- Difficulty thinking or
concentrating or having problems remembering
- Thinking a lot about
death or suicide
If you think you may have depression, take a short quiz to evaluate
your symptoms:
- Are You Depressed?

There are several types of depression that may have different
symptoms and patterns. These include:
- Seasonal affective disorder (SAD).
People who have seasonal affective disorder are depressed only at a certain
time each year, usually in the fall and winter months.
- Premenstrual dysphoric
disorder (PMDD). Women who have regular and severe emotional and
physical premenstrual symptoms that interfere with daily life may have PMDD.
This is similar to
premenstrual syndrome (PMS) but has symptoms that are
more severe.
- Dysthymic disorder (chronic mild
depression) occurs when a person has only 2 to 4 symptoms of depression for a
period of at least 2 years.
- Double depression. This occurs when a
person with dysthymia also has an episode of major
depression.
- Adjustment disorder with depression. Sometimes a
stressful situation can cause temporary symptoms of depression.
Depression impairs your ability to function in your daily life.
However, depression is not diagnosed if your symptoms are due solely to
substance abuse or another medical condition, such as
hypothyroidism.
If you think you have depression after reviewing this list, print the
list and circle those symptoms that apply to you, and then take the list to
your health professional.
If you have just lost someone you care about, you may have symptoms
similar to those of depression. Feelings of sadness, sorrow, and grief are
normal responses to a difficult human experience. Most people start to feel
better over several months. However, if you begin to experience severe feelings
of depression, or if your feelings of sadness don't improve with time, or if
you have suicidal thoughts, you may need treatment.
The U.S. Preventive Services Task Force (USPSTF)
recommends that all adults be screened for depression.2
