What is Unipolar Depression?

"Depression is a treatable illness involving an imbalance of brain chemicals called neurotransmitters. It is not a character flaw or a sign of personal weakness. You canít make yourself well by trying to "snap out of it." Although it can run in families, you canít catch it from someone else. The direct causes of the illness are unclear, however it is known that body chemistry can bring on a depressive disorder, due to experiencing a traumatic event, hormonal changes, altered health habits, the presence of another illness or substance abuse."

As we learn more about depression, science has focused closer attention on the biological causes. This, as well as the myriad studies conducted since the 1950s has changed the core focus of treatment from psychological (in the form of psychotherapy among other types of treatments) to pharmacology.
