Depression and menopause: can acupuncture help?

Depression and menopause. It keeps coming up as a topic and so I’m going to continue to write about it until researchers find an effective way to battle depression during menopause, effective meaning that it is an acceptable strategy for women who prefer alternatives to pharmaceutical agents, effective in that it addresses the underlying causes of depression in menopausal women, including fluctuating estrogen levels, sleep disturbances, night sweats, hot flashes and life factors, and effective in that it is affordable. It’s a tall order, isn’t it?

As I’ve noted time and again, depression is an important issue for many but not all menopausal women, affecting approximately 20% to 40% in a some way or another. Just this week, I wrote about use of the SSRI antidepressants as an alternative to HRT for hot flashes and depression, and possibly as a stop-gap measure until practitioners more widely embrace alternative strategies. On the heels of this study comes another in the  Online Edition of Menopause journal, examining data from one of my favourite studies, ACUFLASH. If you don’t feel like clicking on the link and updates about this study, briefly, in ACUFLASH, researchers randomized 399 postmenopausal women (1 year since last menstrual period) regularly experiencing at least 7 hot flashes daily to acupuncture or no treatment. Moxibustion was used at the practitioner’s discretion and sessions could also be extended by two weeks (from 12 weeks), if needed.  Although the practitioners met beforehand to discuss possible diagnoses and recommended treatment points, all treatment was individualized. Both groups of patients also received self care recommendations, which consisted of a one-page information leaflet on care of menopausal symptoms (e.g. soy, herbs, physical activity and relaxation techniques) which they were free to add at their own discretion.

Overall, the mean frequency of hot flashes declined by 48% in women receiving acupuncture compared with 28% of women using self-care methods only. This means that 50% of women receiving acupuncture experienced a 50% or greater reduction in how often their hot flashes occurred, compared to 16% of women using self-care. Significant reductions were also seen in hot flash intensity. Additionally, the acupuncture group reported significant improvements in vasomotor, sleep, and somatic symptoms over the course of the study.

So, what about acupuncture and depression?

In the current study, researchers examined a sample of 72 women who had participated in ACUFLASH and had either received self-care only or self-care plus acupuncture. At the start, almost 31% of these women reported depressive symptoms and of these, about 17% were determined to suffer from moderate to severe depression (based on a scientific method that measures the severity of depressive symptoms). Although these figures are higher than what is normally seen in the general population, severe depression is often seen among women experiencing very frequent hot flashes (7 or more in a 24 hour period for at least 1 week). And while both groups reported significant declines in depressive symptoms during the 12 week study period by as much as 16%, the declines were similar in both groups, indicating the acupuncture,while helpful for lessening the severity of hot flashes, did not have a specific effect on depression.

If acupuncture doesn’t help depression, why did the results indicate such a high level of improvement that under normal circumstances, an individual could forgo drugs for needles?

A key finding of the original and follow up ACUFLASH studies was the feeling of control over symptoms that was imparted by being educated about self-care. However, here’s the rub: even though acupuncture was shown to significantly benefit both the intensity and frequency of hot flashes, it didn’t provide an edge over depressive symptoms compared to self care alone. The researchers say that this leads them to believe that although a domino effect is at-play (i.e. hot flashes lead to sleep issues lead to symptoms of depression) there is something else that also influences the depression part of the equation.

In the interim, it’s frustrating, right? You can deal with your hot flashes but you still feel blue, low, out of sorts. There is clearly a link between the hot flashes and sleep and depression. It simply needs to be teased out a wee bit further. Keep the faith. We’ll get there!
