People with chronic pain can go for mind-body practices that can exert a protective effect on brain gray matter that counteracts the effects of chronic pain.

M. Catherine Bushnell, scientific director said, "Yoga practitioners have more gray matter than controls in multiple brain regions, including those involved in pain modulation as gray matter increases in yogis correspond to duration of yoga practice. Assessing the impact of brain anatomy on pain reduction, gray matter changes in the internal structures of the cerebral cortex are most significant for pain tolerance."
The study concluded that patients with chronic pain can go for mind-body practices that can exert a protective effect on brain gray matter that counteracts the neuroanatomical effects of chronic pain.
