A thickening of the brain cortex associated with regular meditation or other spiritual or religious practice could be the reason those activities guard against depression ā particularly in people who are predisposed to the disease, according to new research led by Lisa Miller, professor and director of Clinical Psychology and director of the Spirituality Mind Body Institute at Teachers College, Columbia University.
The study, published online by JAMA Psychiatry, involved 103 adults at either high or low risk of depression, based on family history. The subjects were asked how highly they valued religion or spirituality. Brain MRIs showed thicker cortices in subjects who placed a high importance on religion or spirituality than those who did not. The
relatively thicker cortex was found in precisely the same regions of the brain that had otherwise shown thinning in people at high risk for depression.
