Yoga and Dementia: Welcome News

"Dementia Rate Is Found to Drop Sharply, as Forecast”

Now that’s the kind of headline I like to see! Yes, an article in the New York Times this week Dementia Rate Is Found to Drop Sharply, as Forecast announced the results of two different studies that showed that the incidence of dementia—in one case in England and Wales and in the other case in Denmark—was declining. And the reasons for this are very exciting to us here at Yoga for Healthy Aging.

“Yet experts on aging said the studies also confirmed something they had suspected but had had difficulty proving: that dementia rates would fall and mental acuity improve as the population grew healthier and better educated. The incidence of dementia is lower among those better educated, as well as among those who control their blood pressure and cholesterol, possibly because some dementia is caused by ministrokes and other vascular damage. So as populations controlled cardiovascular risk factors better and had more years of schooling, it made sense that the risk of dementia might decrease.”

So what they are saying here is that, along with being better educated, controlling blood pressure and cholesterol can help prevent dementia. And that means yoga can help. Foremost, yoga’s stress management tools can help you keep your blood pressure low. As I discussed in Chronic Stress: An Introduction, living with chronic stress can cause high blood pressure. So practicing stress management (see The Relaxation Response and Yoga and Stress, Your Health and Yoga will help you keep your blood pressure in check as it benefits your health in many other ways. Stress management can also help you maintain a low cholesterol diet by reducing stress eating and giving you more willpower to stay away from high cholesterol foods (see Yoga, Stress and Weight Management and Healthy Eating, Stress and Self Control). Healthy eating is also fostered by mindfulness (see Meditation and Healthy Eating) so if staying away from high-cholesterol foods is a problem for you, a meditation practice may be helpful.

For me, yoga even provides an ongoing education. Yoga philosophy is food for my intellect as well as providing inspiration for living my life with greater equanimity. Why, just this week I learned a lot from Ram’s post LINK, and the week before I learned from writing my own post Modern Yoga and Hinduism. So if yoga philosophy and history are of interest to you, a whole world of new knowledge and intellectual stimulation awaits you.

The New York Times quoted Dr. Anderson, of the National Institute on Aging, saying:

“With these two studies, we are beginning to see that more and more of us will have a chance to reach old age cognitively intact, postponing dementia or avoiding it altogether. That is a happy prospect.”

The Effect of Yoga Poses on Your Mood

by Nina

“To sit in Lotus Pose and gaze at one’s nose is said to be a spiritual practice; to do Lotus Pose and concentrate on the coccyx or elsewhere is said to be a physical practice. Where is the difference? How can Hatha Yoga be only physical and Raja Yoga only spiritual?” —BKS Iyengar

Iyengar sounds a bit cranky in that quote, doesn’t he? I think that’s because back in the 60s he was getting tired of explaining his somewhat radical point of view that doing yoga poses was a form of meditation. Traditionally yoga poses were seen as physical exercises to purify and strength the body for meditation and other spiritual practices. But Iyengar argued that the poses themselves were a spiritual practice.

“A posture can be considered as much a mantra or as much as meditation.” —BKS Iyengar

I thought of this recently when I read an interesting article about a study about the affects of meditation on moods (see Meditation Induces Positive Structural Brain Changes). When I first heard about the article, I thought it was going to be about a study of traditional seated meditation, and I was excited about the possibility that there was proof that traditional meditation helped improve our moods. Instead, I found the study was done using a special form of Chinese meditation called Integrative Body-Mind Training (IBMT) that “differs from other forms of meditation because it depends heavily on the inducement of a high degree of awareness and balance of the body, mind, and environment. And the study found:

“Building on results from a study they published in 2010, investigators found that healthy college-aged volunteers who practiced IBMT for 4 weeks showed significantly improved mood changes compared with those who did not practice the meditation technique.

The researchers note that these mood changes coincided with improved axonal density and expansion of myelin in the anterior cingulate part of the brain, a region that is implicated in self-regulation. Previous research has linked deficits in this brain area with attention deficit disorder, depression, schizophrenia, dementia, and addiction.”

Exciting results, certainly. But doesn’t IBMT sound like Iyengar yoga? I mean, isn’t the practice of yoga poses with a mindful focus on alignment and physical sensations the same as “awareness and balance of the body, mind, and environment”? So it’s pretty easy to extrapolate from this study that Iyengar yoga would have similar effects as this Chinese meditation technique.

Of course I don’t really need a study to tell me what I know from personal experience. My asana practice definitely affects my moods. I usually feel better after practicing almost any sequence, and when I’m feeling depressed or discouraged or stressed, I can intentionally design a practice that can improve my mood. But it’s always nice to find out about studies that back up what I know intuitively because, well, it seems I’m on a mission: I want you, whoever you are, to start practicing, too. Your moods will improve and your stress levels will be reduced, and your overall health will benefit as a result. And now there is the intriguing possibility the practice could also help with dementia (as well as attention deficit disorder, schizophrenia and addiction)!

“Yoga is the harmony of the body, senses, mind, and intellect. That’s why there is no difference between physical and spiritual yoga.” —BKS Iyengar
