We are planning a series of blog posts to highlight some exciting work from our research portfolio. Research we support has led to more than 3,000 peer-reviewed papers; hundreds are published each year. We plan to highlight a few here, choosing examples that illustrate both the promise and the challenges of research on complementary health practices.
Currently one intriguing area is the effect of meditation on the brain. Meditation can be viewed as a kind of ‘mental exercise.’ NCCAM has supported a fair amount of research on its potential health benefits. We still do not have all the answers, but a number of studies support the notion that this ‘mental exercise’ helps regulate attention and emotion and improves the sense of well being. New insights are coming from incorporation of brain-imaging studies into meditation research. In particular, studies suggest that meditation is accompanied by changes in activation of select regions in the brain, particularly the amygdala, a region associated with processing of emotion.
A new NCCAM study, by Desbordes and colleagues, goes further and concludes that the changes in brain function in the amygdala seen during meditation are persistent, enduring even outside meditation sessions. Results were published this month in Frontiers in Human Neuroscience. You can read more about how the study was conducted in our research spotlight. This is a small, single study that fits into the larger body of evidence. I would agree with the authors who noted the need for further research, but I do think the findings provide additional insight into the effects of meditation on the brain—insights that may help to understand the determinants of mental states and the role of traditional practices like meditation in health.
