Improve Treatment Resistant Depression with Mindfulness

Improve Treatment Resistant Depression with Mindfulness

“People at risk for depression are dealing with a lot of negative thoughts, feelings and beliefs about themselves and this can easily slide into a depressive relapse. MBCT helps them to recognize that’s happening, engage with it in a different way and respond to it with equanimity and compassion.” – Willem Kuyken

 

Clinically diagnosed depression is the most common mental illness, affecting over 6% of the population. Major depression can be quite debilitating. It is also generally episodic, coming and going. Some people only have a single episode but most have multiple reoccurrences of depression.  Depression can be difficult to treat and usually treated with anti-depressive medication. But, of patients treated initially with drugs only about a third attained remission of the depression. After repeated and varied treatments including drugs, therapy, exercise etc. only about two thirds of patients attained remission. But, drugs often have troubling side effects and can lose effectiveness over time. In addition, many patients who achieve remission have relapses and recurrences of the depression.

 

Being depressed and not responding to treatment (Treatment Resistant Depression) or relapsing is a terribly difficult situation. The patients are suffering and nothing appears to work to relieve their intense depression. Suicide becomes a real possibility. So, it is imperative that other treatments be identified that can be applied when the typical treatments fail. Mindfulness training is another alternative treatment for depression. It has been shown to be an effective treatment for depression and is also effective for the prevention of its recurrence. Mindfulness Based Cognitive Therapy (MBCT) was specifically developed to treat depression and can be effective even in the cases where drugs fail. In order to identify the best possible treatment, it is particularly important to investigate MBCT’s efficacy for Treatment Resistant Depression relative to other treatments that place equivalent demands upon the patients.

Eisendrath and colleagues compared the relative efficacy of MBCT to a structurally equivalent active comparison condition, a Health-Enhancement Program. They recruited adults who were diagnosed with Major Depressive Disorder who were taking antidepressant medication. They were encouraged to continue their antidepressant medication while participating in the study. They were randomly assigned, stratified by gender, to receive 8-weeks of either standard Mindfulness Based Cognitive Therapy (MBCT) treatment or the Health-Enhancement Program. Both groups met once a week for 2 ¼ hours and were assigned 45 minutes of homework 6 days per week. The MBCT program included training in skills to identify cognitive distortions and to disengage from depression-focused ruminative thinking patterns, body scans, sitting meditations, three-minute breathing spaces, and mindful movement. The Health-Enhancement Program included aerobic exercise, functional movement, music therapy, and dietary education. The participants were evaluated for depression levels, and expectancies of treatment effects before and after treatment and mid-treatment (4-weeks).

 

They found that MBCT, in comparison to the Health-Enhancement Program produced a significantly greater reduction in depression (36.6% vs. 25.3%). In addition, MBCT treatment had a significantly greater proportion of patients respond to treatment. MBCT also produced higher, albeit not significantly different, rates of depression remission (22.4%). The two groups did not differ in their expectations that treatment would be successful, suggesting equivalent placebo effects. Hence, MBCT, was found to be superior to a structurally equivalent Health-Enhancement Program treatment in reducing depression in patients with Treatment Resistant Depression (TRD).

 

These are exciting results and strengthen the case that Mindfulness Based Cognitive Therapy (MBCT) is an effective treatment for the very difficult to treat Treatment Resistant Depression. MBCT uses mindfulness training and cognitive training to allow the patients to reprogram their thought patterns and how they interpret experiences, recognizing that their thoughts are only, just that, thoughts and not reflective of their selves. They learn to experience their emotions but adaptively react to them, seeing them as simply experiences that come and go. This helps them release rumination about past and future problems and focus on the present. This appears to go to the core of the psychological aspects of the disorder and greatly enhance the patient’s ability to cope with their depression.

 

So, improve treatment resistant depression with mindfulness.

 

“MBCT enables people to relate mindfully to the self and with others. The key, it seems, lies in the way MBCT enhances relationships: Less stress about relationships in turn helps prevent future episodes of depression.” – Emily Nauman

Abstract

Background

Due to the clinical challenges of treatment-resistant depression (TRD), we evaluated the efficacy of Mindfulness-Based Cognitive Therapy (MBCT) relative to a structurally equivalent active comparison condition as adjuncts to treatment-as-usual (TAU) pharmacotherapy in TRD.

Methods

This single site, randomized controlled trial compared 8-week courses of MBCT and the Health-Enhancement Program (HEP), comprising physical fitness, music therapy and nutritional education, as adjuncts to TAU pharmacotherapy for outpatient adults with TRD.

The primary outcome was change in depression severity, measured by percent reduction in total score on the 17-item Hamilton Depression Rating Scale (HAM-D17), with secondary depression indicators of treatment response and remission.

Results

We enrolled 173 adults, mean length of current depressive episode was 6.8 years (sd = 8.9). At the end of 8-week treatment, a multivariate analysis showed that relative to the HEP condition, the MBCT condition was associated with a significantly greater mean percent reduction on the HAM-D17 (36.6% versus 25.3%; p=.01) and a significantly higher rate of treatment responders (30.3% versus 15.3%; p=.03). Although numerically superior for MBCT than for HEP, the rates of remission did not significantly differ between treatments (22.4% versus 13.9%; p=.15). In these models, state anxiety, perceived stress, and the presence of personality disorder had adverse effects on outcomes.
