Depression is a type of mood disorder that can range from “having the blues” through dysthymia and all the way to a major depressive disorder. Diagnosis then becomes a matter of placing a patient on this scale to determine which type of treatment will be most useful.
Psychologists use the Diagnostic and Statistical Manual of Mental Disorders along with several accepted written tests, or surveys to diagnose depression in their patients. But one of the main tools is still simply having a meaningful conversation with their patient. One critical factor is to eliminate what are called somatic symptoms – these are black moods due to an underlying illness or medical condition. If a physical cause is found, the expectation is that alleviating this illness will also cure the depression.
After physical causes are eliminated through a medical exam, a medical history and any relevant lab tests, the diagnosis proceeds by scoring a patient on a scale of depression symptoms. These are:
Symptoms are what the patient reports. Signs are what the doctor observes. Some signs of depression are:
A survey in this sense is a test used by doctors to score a patient on a depression index. This is not definitive, but adds support to a diagnosis. There are many such surveys, and a doctor may have a particular one she prefers. They all ask questions about feelings and behaviors related to depression. An example of the type of test used can be found here.
