Does Meditation Promote a Healthy Memory?

An interesting article1 in AARP online describes the benefits of meditating. It cites a study done by Harvard University and Massachusetts General Hospital in 2005. It found that a group practicing meditation for about 40 minutes a day had measurably thicker tissue in the left prefrontal cortex. This is an area of the brain important to cognitive emotional processing and well-being.

At the UCLA Laboratory of Neuro-Imaging the brains of experienced mediators were compared with a control group of nonmediators. The mediators’s brains contained more gray matter than those of the nonmediators. This gray tissue is responsible for high-level information processing especially in the areas associated with attention, body awareness and the modulation of emotional responses.

In a study published in 2010, neuroscientists scanned the brains of volunteers before and after they received eight weeks of training in Mindfulness-Based Stress Reduction (MBSR). They found growth in the hippocampus and shrinkage in the amygdala. As readers of the Healthymemory Blog probably know, the hippocampus is an important part of the brain that is critical to memory and learning. The amygdala is a portion of the brain that initiates the body’s response to stress.

An MRI study at Emory University showed that experienced meditators were much better than a nonmeditating control group at ignoring extraneous thoughts and focusing on the matter at hand when bombarded by stimuli. This capability to focus at will is especially important in today’s multitasking world when we are constantly bombarded by information, often noise, from a variety of sources. This capability grows more important as we age, because research has indicated that the elderly have more difficulty focusing their attention that those who are younger.

Meditation along with positive emotion might even result in a healthier immune system.

This quote from Dr. Richardson is worth remembering. “We know that the brain is the one organ in our body build to change in response to experience and training. It’s a learning machine.”

It should be understood that meditating does not require going to an ashram or sitting in the lotus permission. Here are some guidelines for meditating that were provided in the AARP article.

  1. Sit in any position that’s comfortable for you; a chair is fine. Or, and this is my personal favorite, you can lie down.

  2. Start with a 5-minute session and then gradually increase to longer times.

  3. Start by just feeling your breath as it enters and leaves your nostrils. You don’t need to adjust the breath to make it deeper or finer; simply notice it as it is and as it changes.

  4. Sometimes thoughts or emotions come up and sweep us away, or we fall asleep. Know that your mind will wander, just notice where it went and then gently bring it back to the breath—every time, over and over.

  5. Above all, have patience with yourself. The more you practice meditation, the easier it gets to stay focused. So don’t get discouraged by your wandering mind. Eventually, it will get easier to return to concentrating on your breathing.

I would add that whenever you feel stressed or upset, it is a good idea, if possible, to go someplace where you will no be noticed and try to meditate. Even five minutes can be helpful in such situations.
