Depression in adults

How does my doctor know I have depression?
If you think you might have depression, you should see your doctor. Certain medications, along with some medical conditions and infections, can cause the same symptoms as depression. Your doctor will probably ask you some questions and might also do some blood or urine tests to check for other conditions and infections.
If your doctor can't find a physical cause for the depression, he or she will want to ask you in more detail about your feelings.
Doctors call this a psychological exam. It can also be carried out by a
psychiatrist, a
psychologist or a psychiatric nurse.

There is no laboratory test for depression. To find out whether you're depressed, and to see how depressed you are, your doctor will ask you questions about your feelings
and how you are coping with life.
Your doctor will then put together a complete history of your symptoms: when they started, how long you've had them, how bad they are, whether you've had them before, and whether you've been treated
before. Your doctor might also ask about your alcohol and drug use, whether you've thought about death or suicide, whether
family members have had any type of depression and how it was treated.
Lastly, you should have a mental-status exam to find out if your speech, thought patterns or memory have been affected by your depression. This sometimes happens when
people have depression or a manic-depressive illness, in which they swing between high and low moods.
To find out how bad your depression is, your doctor will first look for one of three key symptoms:

- Feeling sad or low most of the time
- Losing interest in things you used to enjoy
- Having no energy or feeling really tired.
If you have a key symptom, your doctor will consider how many, if any, of the following symptoms you also have:
- Problems sleeping, or sleeping too much
- Poor concentration or difficulty making decisions
- Low self-confidence
- Poor or increased appetite
- Thoughts of suicide
- Agitation or sluggishness
- Feelings of guilt for no reason.
Many people with depression are treated by their regular doctor. However, your doctor might refer you to a psychiatrist, or
you might decide to see one on your own. Psychiatrists specialize in helping people with mental health problems. Your doctor
is especially likely to suggest you see a psychiatrist if you have had depression more than once, or if the treatments your
doctor has tried haven't worked.
