Mindfulness-Based Cognitive Therapy May Improve Depression More Than Fitness Intervention

mindfulness improves depression

In a study by researcher Stuart Eisendrath and colleagues, people with treatment-resistant unipolar depression responded better to an intervention that combined mindfulness training with cognitive therapy than to one that included exercise, nutrition counseling, and music therapy.

The 173 participants had failed to respond to at least two different antidepressant medications. During the study period, all participants were taking an antidepressant, but none were receiving other types of therapy.

After eight weeks, the mindfulness-based cognitive therapy (MBCT) group showed greater improvement in their depression symptoms than the exercise and nutrition group. Of the MBCT group, 29.58% had a large reduction in symptoms, while 17.19% of the comparison group showed a similarly large reduction in symptoms.

A subgroup of the participants also received functional magnetic resonance imaging (fMRI) as part of the study. While completing a task related to emotional working memory, the MBCT group showed enhanced activation of the dorsal lateral prefrontal cortex (to levels seen in non-depressed people). This area is related to executive control of depression and memory functions. The MBCT group also showed reduced activation of the ventral lateral prefrontal cortex compared to the comparison group. Members of the MBCT whose depression symptoms had improved also showed better regulation of the amygdala during the task compared to the exercise and nutrition group.

The research was presented at the 2016 meeting of the American Psychiatric Association.
