Health News Update: Exercise for Depression as Effective as Meds, Psychotherapy
Hello everyone:
More news on brain health and how exercise can boost mood. Here is what they found:
- Researchers reviewed and conducted a multilevel meta-analysis of 218 randomized controlled trials that included 14,170 participants with depression.
- The trials compared different forms of exercise (walking or jogging, yoga, strength training, mixed aerobic exercises, strength training, and Tai Chi or qigong) with other common treatments for depression (therapy, cognitive behavioral therapy or selective serotonin reuptake inhibitors [SSRI]), as well as combination treatments (exercise plus SSRI, aerobic exercise plus therapy, aerobic exercise plus strength training) as well as cycling and dance.
- All findings were presented as "compared with active controls" (e.g., usual care or placebo) and effect sizes measured as Hedges' g, representing the standardized difference between means.
TAKEAWAY:
- Moderate reductions in depression were found for several exercises, regardless of participants' comorbidities
- Across all modalities, effects of exercise were proportional to the intensity prescribed, with a clear dose-response curve, although light physical activity (eg, walking and hatha yoga) still provided some clinically meaningful effects.
IN PRACTICE:
"Our findings support the inclusion of exercise as part of clinical practice guidelines for depression, particularly vigorous intensity exercise. Health systems may want to provide these treatments as alternatives or adjuvants to other established interventions, while also attenuating risks to physical health associated with depression," the authors said.
Bottom Line:
The important part of this review is that exercise is effective and should be considered a component of mental health care…not the only thing that one should do. What they fail to mention is that inflammation will cause, perpetuate, and/or aggravate depression and all mood and cognitive disorders including brain fog. Furthermore, exercise can lower overall inflammation and stress responses but cannot overcome a poor pro-inflammatory dietary pattern. Where I have seen very good results is a combination of an anti-inflammatory food plan, coupled with exercise, optimized sleep, and stress reduction methods coupled with therapy. Such an easy but comprehensive approach not only eases depression, but improves overall health.
