Dr. Arthur Kramer is a professor at the University of Illinois Department of Psychology, the Campus Neuroscience Program, Beckman Institute and the Director of the Biomedical Imaging Center at the University of Illinois.
I am honored to interview today for the results of recent brain research on how active the brain health.
Alvaro Fernandez (AF): Dr. Kramer, thank you for your time. We begin to try to clarify some of the currentMisunderstanding and controversy. From what we know today, and your recent Nature piece (Note: referenced below), what are the 2-3 key lifestyle habits would you suggest a person's health decisions, the brain wants to delay Alzheimer's symptoms and improve in general?
Dr. Kramer (DK): First, be active. You train. Aerobic exercise, 30 to 60 minutes per day three days a week, it was shown that the effects of a series of experiments. And there is no need to do something strenuous:walk, showed that effect. There are many unanswered questions with regard to certain types of movement, the duration, the magnitude of the effect ... But as we have in our recent article in Nature Reviews Neuroscience wrote, there is no doubt that leading a sedentary life is bad for our cognitive health. Cardiovascular exercise seems to have a positive effect.
Second Life-care intellectual engagement. There is plenty of research prospective observational study shows that while more intellectuallystimulating activities reduces the risk of developing Alzheimer's symptoms.
Let me add, given all the media hype that not "brain games", especially in front has been found time to have a long-term impact on Alzheimer's disease or the maintenance of knowledge over time. It 's too early and consumers should be aware of this fact. It 'true that some companies are becoming more scientifically valid than others, but from my point of view of consumer-oriented sector is growing faster thanSearch.
Ideally, the physical and mental stimulation, combined with social interaction. Why not a nice walk with friends to discuss a book? We lead a very busy life, so the more integrated and interesting activities are, the more likely we will.
AF: great idea: a book club on foot! Now a part of the confusion we see in the search for the magic formula that will work for everyone and everything. We prefer to speak several columns brainHealth and different priorities for different people. Can you clarify what interventions seem to have a positive effect on specific cognitive abilities, and individuals?
DK: Maybe one day we will be based on the location of specific actions for individuals on genetic testing is recommended for example, but we have no idea today. We are only beginning to understand how the environment interacts with our genome.
But I agree on the premise that it is probably not a generalSolution that solves all of cognitive problems, but we have a variety of approaches. And we must not forget, for example, the cognitive benefits of smoking cessation, sleep disorders, pharmacological interventions, nutrition, social engagement.
Physical activity tends to be rather broad effects on different forms of perception and cognition, have seen published in the Colcombe and Kramer, 2003, Meta-analysis in Psychological Science (Note: referenced below).
Cognitive training for aVariety of perceptual and cognitive domains - has shown little, but the transfer of tasks for training.
No single type of intervention is sufficient. Today, there is no clear research on how these factors interact with different lifestyles as possible. The National Institute on Aging began the research sponsors exactly this address.
AF: Finally, explain what in your mind the best way to determine the relative benefits of physical perception vs. cognitive? Basically, it seemsclear that physical activity may contribute to neurogenesis (Note: the creation of new neurons), but the perception of cognitive learning and for the survival of neurons with strengthened synapses so that I can see how these two "pillars "are like a free" one or the other. "
DK: I agree. Given what we know now, I am the intellectual and physical effort would be recommended. But we know from studies of different animals that exercise has a number ofThe effects on the brain of neurogenesis, including increases in various neurotransmitters, nerve growth factors and angiogenesis (formation of new blood vessels).
AF: Dr. Kramer, thank you for your time.
DK: You are cordially invited.
