Mindfulness-Based Stress Reduction Equivalent to Escitalopram for Treatment of  Anxiety Disorders

Hoge et al reported in JAMA Psychiatry (2022) that in a randomized clinical trial of 276 adults with anxiety disorders, 8-week treatment with mindfulness-based stress reduction (MBSR) was noninferior to escitalopram.  The “MBSR is a manualized 8-week protocol with weekly 2.5-hour long classes, a day-long retreat weekend class during the fifth or sixth week, and 45-minute daily home practice exercises…. Qualified instructors taught the theory and practice of several forms of mindfulness meditation, such as breath awareness (focusing attention on the breath and other physical sensations), a body scan (directing attention to one body part at a time and observing how that body part feels), and mindful movement (stretching and movements designed to bring awareness to the body and increase interoceptive awareness)….Escitalopram was initiated at 10 mg daily orally and increased to 20 mg daily at week 2 if well tolerated or delayed if not.”  The investigators concluded that “mindfulness-based stress reduction was a well-tolerated treatment option with comparable effectiveness to a first-line medication for patients with anxiety disorders.”

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.

Mindfulness Therapy Improves Anxiety in Youth with a Bipolar Parent

Children of parents with bipolar disorder are prone to anxiety and emotional dysregulation, but treating these symptoms with antidepressants can provoke symptoms of mania. Thus, non-pharmacological treatements for anxiety and depression are needed. A recent study by Melissa DelBello found that twelve weeks of mindfulness-based cognitive therapy improved symptoms of anxiety and mood dysregulation in 20 youth with a bipolar parent. DelBello used functional magnetic resonance imaging (fMRI) to observe that the therapy increased activation of brain structures related to emotion and sensing. Amygdala activation differed between those with anxiety and those with mood dysregulation, suggesting that the therapy’s effect was on regions that modulate the amygdala, including prefrontal and insular regions, rather than on the amygdala itself.

Mindfulness Interventions May Reduce Substance Use and Cravings

A 2014 meta-analysis of the literature to date on mindfulness-based interventions (MBIs) for substance use disorders suggests that these interventions can reduce consumption of alcohol, cocaine, amphetamines, marijuana, cigarettes, and opiates, compared to several types of controls. The research by Alberto Chiesa and Alessandro Serretti, published in the journal Substance Use and Misuse, includes 24 studies published before 2012. The authors also found some evidence that  MBIs are associated with reduced craving and increased mindfulness. Most of the studies included in the meta-analysis were small, so their generalizability is limited.

A 2014 article by S. Bowen and colleagues in the journal JAMA Psychiatry compared mindfulness-based relapse prevention with standard relapse prevention and treatment as usual for people recovering from substance abuse. Mindfulness-based relapse prevention combines the cognitive behavioral approach of standard relapse prevention with MBIs that have been successful in other studies.

Bowen et al. found that both standard relapse prevention and mindfulness-based relapse prevention lowered the risk of relapse and reduced days of substance use at 6 months, compared to treatment as usual. The standard treatment delayed first drug use, but the mindfulness intervention decreased use at the 12-month mark compared to both standard relapse prevention and treatment as usual.
