Abstract

CONTEXT:

The neurobiological effect of yoga on the cortical structures in the elderly is as yet unknown.

MATERIALS AND METHODS:

Seven healthy elderly subjects received yoga intervention as an add-on life-style practice. Magnetic resonance imaging scans were obtained before and 6 months later. Voxel-based-morphometric analyses compared the brains before and after the yoga.

RESULTS:

Yoga group was found to have increases in hippocampal, but not in occipital gray matter.

CONCLUSION:

Yoga has potential to reduce neuro-senescence. Small sample size and absence of the control group prevent generalization of the findings limiting its translational value.

KEYWORDS:

Elderly; hippocampus; magnetic resonance imaging; yoga
