Characteristics Observational cohort Longitudinal Peer reviewed
Sample size 44
Population Patients with chronic migraine and medication overuse (ICHD-3Beta codes 1.3 and 8.2) who completed an inpatient withdrawal program
Interventions Mindfulness-based training Prophylactic Medications
Duration 6 weekly mindfulness sessions; follow-up at 3, 6, and 12 months after withdrawal
Measures Headache diaries, Headache Impact Test (HIT-6), Migraine Disability Assessment (MIDAS), State-Trait Anxiety Inventory (STAI Y1-Y2), Beck Depression Inventory (BDI)
Topics Meditation
Keywords Chronic migraine Medication overuse Pharmacological prophylaxis
Key findings Patients receiving mindfulness training without prophylactic medication showed improvements in headache frequency, medication use, disability, and depression that were substantially similar to those receiving prophylactic medication over 12 months. Both groups had significant and equivalent rates of 50% or greater headache reduction, and most patients in each group no longer met criteria for chronic migraine.

Abstract

Chronic Migraine (CM) is a disabling condition, worsened when associated with Medication Overuse (MO). Mindfulness is an emerging technique, effective in different pain conditions, but it has yet to be explored for CM-MO. We report the results of a study assessing a one-year course of patients' status, with the hypothesis that the effectiveness of a mindfulness-based approach would be similar to that of conventional prophylactic treatments. Patients with CM-MO (code 1.3 and 8.2 of the International Classification of Headache Disorders-3Beta) completed a withdrawal program in a day hospital setting. After withdrawal, patients were either treated with Prophylactic Medications (Med-Group), or participated in a Mindfulness-based Training (MT-Group). MT consisted of 6 weekly sessions of guided mindfulness, with patients invited to practice 7-10 min per day. Headache diaries, the headache impact test (HIT-6), the migraine disability assessment (MIDAS), state and trait anxiety (STAI Y1-Y2), and the Beck Depression Inventory (BDI) were administered before withdrawal and at each follow-up (3, 6, 12 after withdrawal) to patients from both groups. Outcome variables were analyzed in separate two-way mixed ANOVAs (Group: Mindfulness vs. Pharmacology x Time: Baseline, 3-, 6-, vs. 12-month follow-up). A total of 44 patients participated in the study, with the average age being 44.5, average headache frequency/month was 20.5, and average monthly medication intake was 18.4 pills. Data revealed a similar improvement over time in both groups for Headache Frequency (approximately 6-8 days reduction), use of Medication (approximately 7 intakes reduction), MIDAS, HIT-6 (but only for the MED-Group), and BDI; no changes on state and trait anxiety were found. Both groups revealed significant and equivalent improvement with respect to what has become a classical endpoint in this area of research, i.e. 50% or more reduction of headaches compared to baseline, and the majority of patients in each condition no longer satisfied current criteria for CM. Taken as a whole, our results suggest that the longitudinal course of patients in the MT-Group, that were not prescribed medical prophylaxis, was substantially similar to that of patients who were administered medical prophylaxis.
