Everyone experiences variations in mood - transitory blues, disappointments, the normal grief that accompanies the loss of someone you love. But a severe or prolonged depression
that interferes with the ability to function, feel pleasure, or maintain interest is not a mere case of the blues. It is an illness. Researchers have demonstrated that it results from biochemical imbalances in the brain.
In depression faith in deliverance, in ultimate restoration, is absent. The pain is unrelenting, and what makes the condition intolerable is the foreknowledge that no remedy will come not in a day, an hour, a month, or a minute. It is hopelessness even more than pain that crushes the soul. - William Styron, 1990
Depression is one of the most common mental disorders affecting approximately 340 million people in the world. No one is immune from depression - it occurs in people of all social classes, all countries and all cultural settings.
One in four women and one in ten men can expect to develop depression during their lifetime, but it's not just adults who suffer. Depression affects at least one in 50 children under 12 and one in 20 teenagers.
A depressive disorder is an illness that involves the body, mood, and thoughts. It affects the way a person eats and sleeps, the way one feels about oneself, and the way one thinks about things. A depressive disorder is not the same as a passing blue mood. It is not a sign of personal weakness or a condition that can be willed or wished away. People with a depressive illness cannot merely "pull themselves together" and get better. Without treatment, symptoms can last for weeks, months, or years.

Diagnosis of Depression
The first step
to getting appropriate treatment is a complete physical and
psychological evaluation to determine whether the patient has depressive
illness, and of what type it is.
A good diagnostic evaluation also will include a complete history of the
symptoms, i.e., when they started, how long they have lasted, how
severe they are, whether the patient had them before and, if so, whether
they were treated and what treatment they received.
Alcohol and drug abuse should be asked about.
Further, a history should include questions about whether other family
members have had a depressive illness.
Last, a diagnostic evaluation will include a mental status examination
to determine the speech and memory pattern.
Treatment for Depression
Clinical depression is one of the most treatable medical illnesses and getting treatment can save lives.
The choice of treatment depends on how severe the depressive symptoms are and the history of the illness.
The most commonly used treatments are antidepressant medications, psychotherapy, or a combination of the two.Medication
Antidepressant medication acts on chemical pathways of the brain.
The two most common types are selective serotonin reuptake inhibitors (SSRIs) and tricyclic antidepressants (TCAs).
Antidepressant medications are not habit-forming. It may take up to eight weeks to notice an improvement.
Electro convulsive therapy (ECT)
Therapy can be effective in treating clinical depression, especially depression that is less severe.
Scientific studies have shown that short term (10-20 weeks) courses of therapy are often helpful in treating depression.
Cognitive/behavioral therapy helps change negative styles of thinking and behavior that may contribute to clinical depression.
Interpersonal therapy focuses on dealing more effectively with other people, working to change relationships that can cause or worsen clinical depression.
In the past few years, much interest has risen in the use of herbs in the treatment of both depression and anxiety.
Hypericum perforatum, an herb used extensively in the treatment of mild to moderate depression in Europe, has recently aroused interest around the world. However, the scientific studies that have been conducted on its use have been short-term and have used several different doses.
