Distinguishing between those depressions that include a significant biological component (and that therefore might respond to medication) and those that do not presents an important challenge for the non-medical therapist. The decision is complex and must consider the personality makeup, social context, and clinical presentation of the counselee. The process cannot be reduced to a checklist used to arrive at a definite conclusion. However, the following distinctions usually are true, and if clients show several symptoms Indicative of major depression, it probably is wise to refer them for a medication evaluation.
Mild depressions often occur as a reaction to an event, and will usually be diagnosed as adjustment disorders either with depressed mood or with mixed emotional features (DSM-III-R 309.00 or 309.28). Adjustment disorders that become severe and last for more than two weeks can become major depressive episodes.
A major depressive episode (sometimes called "neurotransmitter illness") occurs when the depression becomes intense enough that it not only affects one's thoughts and mood, but also affects the functioning of certain neurotransmitters (such as dopamine, serotonin, and norepinephrine) in the brain. These depressions usually should be diagnosed as a depressive disorder (either a single episode or recurrent; 296.2x or 296.3x). Major depressive episodes sometimes last up to eighteen months.
The major differences between milder depression and major depression are the duration and intensity of symptoms. The chart lists some typical differences between milder and major depression. Some experts suggest that antidepressants can be used profitably under any of the following situations:

Check as many symptoms as apply. If a person has several symptoms that meet the criteria for major depression, the non-medical therapist should not try to make a diagnosis of major depression. They may tell the counselee that they appear to have several symptoms of biological depression, and refer them to a physician or psychiatrist for evaluation and treatment. Such people can often benefit from continued supportive counseling in addition to medical treatment for the biological component of their depression.
