The neural correlates of mindfulness-based therapy on anxiety : A systematic review

Sammanfattning: Anxiety is a high-prevalence disorder, and it is often treated by medication which can be costly, has side effects, and is not available for everyone in need. Mindfulness-based interventions (MBIs) such as mindfulness-based stress reduction (MBSR) and mindfulness-based cognitive therapy (MBCT) are great alternatives to treat anxiety. Both MBIs are not only more accessible but have no side effects as well. To establish whether MBIs can become a main treatment for anxiety, the associated neural correlates and changes should be investigated further. The aim of this systematic review is to investigate whether neural correlates of MBIs are mainly caused by emotional or attentional neural mechanisms, or if both are involved. There were five studies selected and included according to a set of inclusion and exclusion criteria. The results suggest that MBIs are in fact effective in alleviating anxiety symptoms by enhancing both emotion and attention regulation. However, several of the included studies came with limitations such as having no significance in p-values, no control groups, and small samples. Thus, further research is needed to draw a conclusion on whether MBIs are the best alternative for the alleviation and treatment of anxiety.
