NEW YORK -- For people at high risk of depression because of a family history, spirituality may offer some protection for the brain, a new study hints.

Parts of the brain's outer layer, the cortex, were thicker in high-risk study participants who said religion or spirituality was "important" to them versus those who cared less about religion.

"Our beliefs and our moods are reflected in our brain and with new imaging techniques we can begin to see this," Myrna Weissman told Reuters Health. "The brain is an extraordinary organ. It not only controls, but is controlled by our moods."

Weissman, who worked on the new study, is a professor of psychiatry and epidemiology at Columbia University and chief of the Clinical-Genetic Epidemiology department at New York State Psychiatric institute.

While the new study suggests a link between brain thickness and religiosity or spirituality, it cannot say that thicker brain regions cause people to be religious or spiritual, Weissman and her colleagues note in JAMA Psychiatry.

It might hint, however, that religiosity can enhance the brain's resilience against depression in a very physical way, they write.

Previously, the researchers had found that people who said they were religious or spiritual were at lower risk of depression. They also found that people at higher risk for depression had thinning cortices, compared to those with lower depression risk.

The cerebral cortex is the brain's outermost layer made of gray matter that forms the organ's characteristic folds. Certain areas of the cortex are important hubs of neural activity for processes such as sensory perception, language and emotion.
