Yoga associated with elevated brain GABA levels May 27, 2007Posted by Dreamhealer in Research.
Researchers at Boston University School of Medicine (BUSM) and McLean Hospital have found that practicing yoga may elevate brain gamma-aminobutyric (GABA) levels, the brain’s primary inhibitory neurotransmitter. The findings, which appear in the May issue of the Journal of Alternative and Complementary Medicine, suggest that the practice of yoga be explored as a possible treatment for depression and anxiety, disorders associated with low GABA levels.
The World Health Organization reports that mental illness makes up to fifteen percent of disease in the world. Depression and anxiety disorders both contribute to this burden and are associated with low GABA levels. Currently, these disorders have been successfully treated with pharmaceutical agents designed to increase GABA levels.
Using magnetic resonance spectroscopic imaging, the researchers compared the GABA levels of eight subjects prior to and after one hour of yoga, with 11 subjects who did no yoga but instead read for one hour. The researchers found a twenty-seven percent increase in GABA levels in the yoga practitioner group after their session, but no change in the comparison subject group after their reading session. The acquisition of the GABA levels was done using a magnetic resonance spectroscopy technique developed by J. Eric Jensen, PhD, an assistant professor of psychiatry at Harvard Medical School and an associate physicist at McLean Hospital. Read More on this topic….
