Depression
Clinical Research Advances in Treatment
Thanks to research advances over the
past 30 years, depression is highly treatable. An estimated 80% of
patients experience improvement in symptoms within four to six
weeks of beginning treatment with an antidepressant drug. Cognitive
therapy, which teaches patients to control negative thoughts and
the depressed emotions they triggered, is also effective in
relieving symptoms.
Today's antidepressants target the
storage, release and metabolism of neurotransmitters in various
ways. Early antidepressants, like MAOIs (monoamine oxidase
inhibitors) and tricyclic drugs targeted serotonin and/or
norepinephrine.
Newer antidepressants include SSRIs
(selective serotonin reuptake inhibitors, such as Zoloft and Paxil)
and SNRIs (serotonin and norepinephrine reuptake inhibitors, such
as Cymbalta and Pristiq) have fewer side effects than earlier
drugs. However, recent findings have raised concerns about
increased risks for suicide in some patients, particularly in
adolescents and children, who take some types of antidepressant
drugs.
Despite effective treatment, more
than half of people suffering from depression never seek therapy.
Among patients treated, an estimated 50% stop taking their
medication and suffer recurrences. Recent studies suggest that the
most effective therapy combines medicine with psychotherapy, like
cognitive therapy, and includes ongoing care to support patients in
the context of their relationships and work lives.
The effort to increase awareness and
understanding is one of the greatest challenges in advancing the
treatment of depression. A number of organizations offer
information and support, including the National Institutes of
Mental Health (www.nimh.nih.gov),
the Depression and Bipolar Support Alliance (www.dbsalliance.org),
and Mental Health America (www.nmha.org).
