A recent review of complementary and alternative therapies in the treatment of depression are quite promising.  A study review of the medical literature, conducted by the American Psychiatric Association’s Task Force on Complementary and Alternative Medicine reported its findings  in the June, 2010  Journal of Clinical Psychiatry.

 

The following is a brief overview of the task force’s findings:

 

  • Several studies have determined that the omega-3 fatty acids are beneficial when used as an antidepressant supplement. However, there are limited and conflicting results regarding their use as a singular therapy for major depression, and doses are not included.
  • Several trials have indicated that supplements of  S-adenosyl-L-methionine (SAMe)—the major donor of methyl groups in human metabolism—are as effective as antidepressants in treating major depression.
  • Exercise has been studied both as single therapy and as an antidepressant adjunct. Trial results have generally been positive in both men and women across a wide age range and irrespective of setting or mode. Also, patients who continued to exercise following study participation had a lower risk of relapse over several months to years.

 

In one study, for example, exercise’s effectiveness as a single therapy for mild to moderate major depressive disorder was tested in men and women aged 20 to 45. Some participants exercised from 1.5 to 3 hours a week, others 80 minutes a week, and still others served as controls. After 12 weeks, the high-exercise group showed a 47 percent reduction in symptoms, while the low-exercise and control groups showed a 30 percent reduction in symptoms. The differences were statistically significant.

 

  • Although there is strong evidence that light therapy can counter seasonal depression, the effectiveness of light therapy as a treatment for major depression is not as well established. Also, it appears that light therapy might be even more effective against major depression if it is combined with an antidepressant than if used alone.

 

In one randomized, controlled trial, for instance, 102 subjects were treated with the drug Zoloft.  The participants  also received either supplemental treatment with 30 minutes of either bright morning (10,000 lux) or dim red (50 lux) light for five weeks. All clinician and self-report measures significantly favored active light augmentation.

 

  • Review of St. John’s Wort, trials suggest that it is more effective for mild to moderate depression than for the severe form of the illness.
  • Studies have failed to demonstrate the therapeutic effectiveness of acupuncture compared with a control condition for the treatment of major depression.
  • Folates’s  effectiveness as a single therapy for major depressive disorder has yet to be adequately tested. A few trials have found folate to be efficacious and well tolerated, although the best dose and form of folate remain unclear.

 

The task force also reviewed the side effects and costs of these therapies. It found, for example, that the omega-3 fatty acids have a low risk of side effects and are inexpensive, that SAMe  has a relatively low risk of side effects and is expensive, and that St. John’s wort carries a risk of interactions with drugs such as antiretrovirals, immunosuppressants, antineoplastic agents, anti-coagulants, and oral contraceptives.

 

“The sheer scope of CAM use in the U.S. is fascinating and somewhat daunting,” Freeman said. “Over 40 percent of adults use at least one CAM treatment annually, demonstrating how accessible and attractive these treatments are to our patients. However, we found that very few CAM treatments [for major depression] have received rigorous study. Our task force hopes that our report will serve as a foundation for future research in this area…. Any treatment for a serious psychiatric disorder, whether considered CAM or conventional, needs to be rigorously studied for effectiveness and safety.”
