You Are Not Prisoner of Your DNA

November 8, 2014

Unfortunately, the belief that we are prisoners to our own DNA is used as a cop out from personal responsibility. It is also the first key thing that Dr. Dharma Sing Khaisa, who is the Founding President and Medical Director of the Alzheimer’s Research and Prevention Foundation, would like every person to understand about his/her own brain, thinks that is commonly misunderstood. The second key thing is, “You can improve your brain function, regardless of your age and stage in life. He is an MD who has been working in this area for more than 20 years, and he says that he is more excited than ever about the possibilities for enhanced mental performance and brain longevity for everyone.

When he started his research he discovered that chronic stress , via release from the adrenal glands, kills brain cells by the thousands in the hippocampus, which is critical to memory performance. He realized that this could lead to Alzheimer’s Disease and other problems. He also knew from his own research and personal experience that lifestyle modifications, especially including yoga and meditation could remedy that. He is continuing his research looking into the integrative approach to the preventon of Alzheimer’s. He is especially interested in continuing to explore the multiple positive benefits of a simple brain-enhancing yoga meditation exercise called Kirtan Kriya, or KK.

He believes that it is important to champion the belief that lifestyle can influence brain fitness and to encourage people to make their brain health their top priority. Personally, he remembers to put his brain health first. He practices yoga and meditation every day, has a serious work out regimen five times a week, and watches his diet. As for mental exercise, he writes songs and plays music, which is also great fun.

This post reiterates the goals of the healthymemory blog, which is important to do periodically.

Mindful Awareness

March 25, 2014

This post is based on Siegel’s Pocket Guide to Interpersonal Neurobiology who describe mindful awareness as a form of awareness in which we are alert and open to present experience without being swept up by judgments and prior expectations. This implies discernment or a moral stance that is one of positive regard for others, and a nonjudgmental awareness that is imbued with acceptance at its core, of compassion towards oneself and others.
A direct quote from 6-3 of the Pocket Guide follows: “Studies of those with mindful awareness using a broad application of these features reveal that it is of benefit to the health of the mind, in terms of balanced emotional regulation, flexibility, and approaching rather than withdrawing from challenging events. Being mindful makes you more empathic and improves the health of relationships. And being mindful improves the health of the body in terms of enhanced immune function and increased telomerase—the enzyme that maintains the telomeres at the ends of chromosomes and thus enhances cellular longevity. Mindfulness also helps you have more resilience in the face of chronic pain. Mindful awareness helps minds, relationships, and our embodied lives.”
Mindful awareness practices are available for children and adolescents as well as for adults, so mind-training practices have the potential to promote well-being and resilience throughout the life span. According to the annotated index mindful awareness practice is skill building training that focuses attention on intention and the cultivation of awareness of awareness. Repeated and regular practice has been shown to strengthen to regulate emotion and attention, improve empathy and insight, promote healthy immune functioning, move the electrical activity of the brain toward a “left shift” of approaching challenging situations and increase the activity and growth of regulatory and integrative regions of the brain. Examples of mindful awareness practices include mindfulness meditation, centering prayer, yoga, and tai chi chuan. More examples of mindfulness and meditation can be found by entering “mindfulness” or “meditation” into the healthymemory blog search block.
These practices have affected the integrated areas of the brain that link the cortex, limbic area, brainstem, and social inputs from other brains. These areas influence executive function to include emotional regulation and the focus of attention, as well as emotional and social intelligence. Included here are the anterior and posterior cingulate , the orbitofrontal cortex, and both the medial and the ventral aspects of the preftontal region, including the insula and the limbic hippocampus.

APS Session on Cognitive Reserve

June 5, 2013

The title of the session was “Cognitive Reserve in Aging: Can Leisure Activities Increase Neuroplasticity?” and was chaired by Brenda-Hanna-Piaddy of the Emory School of Medicine. The first presentation was by Sara Lazar of the Massachusetts General Hospital and Harvard University, and was titled, “Can Meditation and Yoga Slow Aging”. She was speaking of mindfulness meditation (on which you can find many healthymemory blog posts) and practitioners of Yoga that is strong on meditation and weak on strenuous positions. Practitioners excelled at a wide variety of cognitive tests, and performance on these cognitive tasks as they aged declined much more slowly than non-practitioners. Measures of the brain, such as cortical thickness, increases in white and gray matter, and the hippocampi, which are critical for memory, were larger than non-practitioners and decline less with aging. Now these people had been practicing for 30 or more years for at least five times per week. Be reassured that you don’t need to practice for this long for meditation to be beneficial. Every little bit helps, but the sooner one starts and the more one practices, the more benefits will be reaped. But it is never too late to begin.

Something I have never seen regards the question of how may victims of dementia or Alzheimer’s can be found among Buddhists Monks and other practitioners of meditation. Are there any? If so, is there data on the rate of incidence. If anyone knows the answer, or where to find the answer, please leave a comment. It will be much appreciated.

Chandramalika Bask, of the University of Texas at Dallas, gave a presentation on the benefits of video games. Apparently the beneficial video games are strategy games, not shooter games. These are real time strategy games that involve a number of tasks and the need to switch between and prioritize tasks. The benefits of playing these games were manifest in both cognitive tasks and in measures of the brain. They clearly slowed cognitive decline. One of the pluses of video games is that they are fun and people continue to play them. People are less likely to stick to regimes of meditation or physical exercise.

Brenda-Hanna-Piaddy made a presentation on the Neural Networks Subserving Enhanced Condition in Older Musicians. Her study involved 140 amateur musicians and non musicians with ages ranging from 59-83. The amateur musicians were divided into two groups, those with from 1 to 9 years of experience, and those with 10 or more years experience. A subset of 24 in these groups underwent fMRIs. The bottom line was that as assessed by cognitive tests and brain imaging, there were clear advantages for the musicians, and the more musical experience, the better. The bottom line was that music is a viable model for cognitive stimulation. Again, I would like to know the incidence of dementia and Alzheimer’s among retired musicians and aging amateurs. The current goal seems to be is reducing the onset of dementia. It should be realized that conscientious researchers tend to be conservative and do not want to over promise. But I am certain that there are individuals who live to be very old with limited or no cognitive decline. Articles about people who live to be quite old are frequently seen. My question is what is their cognitive status?

The final presentation was by Denise Park of the University of Texas at Dallas. Her presentation was on the relative benefits of active versus passive social interactions. Although social interactions are generally regarded as beneficial to memory health, the question here was whether the nature of the group would be more beneficial. So there were three groups with productive goals that involved learning something novel. One involved quilting, one involved photography, and one involved both with the time split 50/50 between the two groups. There were three receptive groups made to be as comparable as possible to the three active groups except that their activities involved nothing novel. The fMRI images indicated brain benefits fot the three productive groups. With respect to cognitive performance, the photo group showed improved verbal memory, the Quilting group showed improved cognitive control, and the group that involved both, showed improvements in both verbal memory and executive control.

All these studies are interesting and worthwhile, but I would like to see some retrospective studies in which people of advanced age who were still mentally sharp were studied. Retrospective studies are not very popular because their results are ambiguous. Even if the individuals accounts of his life are accurate, it is still possible that there is some unknown gene or combination of genes responsible for his mental alacrity. I feel that such research would still be informative and such life stories would also be inspirational and could provide good models for people to follow. Web searches on retrospective studies of dementia have not been successful. Again, if you know of any such studies, please comment.
