Depression As An Illness

Depression has been determined by the World Health Organization(W

Although the exact causes of depression remain unknown, the current thinking is that depression is a disease that is in part hereditary and is often associated with current or early life stress. This combination of genetic and environmental factors causes specific changes in brain chemicals such as serotonin, norepinephrine or dopamine that may explain some of the depressive symptoms.

Fortunately,  safe and effective treatment is now available for depression and other mood disorders. The most adequate treatment is a combination of pharmacotherapy and psychotherapy. Pharmacotherapy with medications such as a selective serotonin reuptake inhibitor (SSRI) or "new generation" antidepressants along with cognitive behavior therapy (CBT) will provide symptomatic relief for most patients with depression. Medications are also available to "prevent" recurrent episodes of depression or mania, particularly in patients who suffer from bipolar disorder. These "mood stabilizers" include lithium and anticonvulsant medications such as valproic acid and lamotrogine.

As scientists are trying to learn more about brain mechanisms associated with depression, researchers are working hard to develop newer antidepressants that will lessen the burden of the illness. Several exciting new compounds loom on the horizon. There is also experimental evidence that psychosocial treatment can be effective. Yes, there is light at the end of the tunnel, even for the most depressed individuals.
