Study on the effect of mindfulness on episodic migraine

Migraine is one of the leading causes of disability worldwide, with severe symptoms such as recurrent headaches, nausea and extreme sensitivity to light. Psychosocial factors, particularly stress, are identified as common triggers of migraine attacks.

One promising therapy is mindfulness training, which is mainly used in the Mindfulness-Based Stress Reduction (MBSR) method. This 8-week, empirically supported therapy aims to promote mindfulness and acceptance of physical and emotional sensations in order to alleviate chronic pain symptoms.

A recent large-scale study by Seminowicz et al. analyzed the effect of MBSR on migraines. In the study, patients suffering from episodic migraine were assigned to either anenhanced MBSR therapy or a stress management control group. The MBSR program included an additional eight weeks of more intensive sessions.

The results showed that the MBSR+ group achieved a significant reduction in headache frequency and associated disability compared to the control group. 52% of MBSR patients reported a significant improvement compared to 23% in the control group.

The clinical improvements in the MBSR+ group persisted 52 weeks after treatment, indicating the long-term effects of this intervention. Interestingly, however, there were no significant differences in primary structural and functional MRI results between the two groups. Nevertheless, secondary imaging results showed that the MBSR+ group had a lower fMRI response to cognitive tasks and reduced brain connectivity during rest compared to the control group. These changes could indicate improved cognitive efficiency.

The study shows that MBSR is an effective treatment option for episodic migraine. It highlights the need to further investigate the neurobiological mechanisms behind the effectiveness of mindfulness training for migraine in order to further optimize long-term therapeutic strategies.
