The Science of Brain Renewal Meditation

What does science know about the benefits of meditation?

Follow this link if you are looking for the glossary of scientific terms.

There are an estimated 1,500 published research papers linked to meditation, mindfulness and related forms of brain training. Although they generally demonstrate  the positive effects of meditation, drawing precise conclusions from the entire body of work it not possible. However careful study of the most reliable research, combined with evidence from traditional meditation sources allows for some strong conclusions about the benefits of meditation to be arrived at. Below we provide links to some of the key research cited across the website.

  1. Age-related cognitive decline begins in the 20s and 30s
  2. About 50 million people worldwide suffer from dementia, the number of sufferers is expected to grow to around 130 million within 30 years.
  3. The brains of regular meditators appear several years younger than non-meditators.
  4. Meditators found to have increased cortical thickness compared to non-meditators, meditation correlated with increased brain structure.
  5. Research demonstrates that cognitive decline is already evident at the age of 45.
  6. Meditation linked to lower risks of cognitive decline.
  7. Long term meditators have increased brain structures.
  8. Meditation has been linked with improved cognitive function in older adults, even those suffering from age related cognitive decline.
  9. Meditation appears to be a key factor in the reduced risk of cognitive decline, although other lifestyle factors may also be important.
  10. Meditation research has a number of problems to confront, not least methodological flaws. However this meta review does point to some evidence that the teacher – student relationship is influential in meditation practice.
