Meditation may boost memory, a recently published preliminary study shows. In an experiment involving a group of older adults--all of whom had some degree of memory impairment at the study's start--researchers found that regular meditation practice helped improve blood flow to the brain.
For eight weeks, 14 study members practiced a daily 12-minute meditation exercise known as Kirtan Kriya. Tests conducted at the end of the eight-week period showed that the participants had an increased blood flow in brain regions involved in retrieving memories. The study members also had improved performance on tests measuring cognitive function, memory, and attention.
