Dr. Arthur Kramer is a Professor in the University of Illinois Department of Psychology, the Campus Neuroscience Program, the Beckman Institute, and the Director of the Biomedical Imaging Center at the University of Illinois.
I am honored to interview him today.
Dr. Kramer, thank you for your time. Let’ start by trying to clarify some existing misconceptions and controversies. Based on what we know today, and your recent Nature piece (referenced below), what are the 2–3 key lifestyle habits would you suggest to a person who wants to delay Alzheimer’s symptoms and improve overall brain health?
First, Be Active. Do physical exercise. Aerobic exercise, 30 to 60 minutes per day 3 days per week, has been shown to have an impact in a variety of experiments. And you don’t need to do something strenuous: even walking has shown that effect. There are many open questions in terms of specific types of exercise, duration, magnitude of effect but, as we wrote in our recent Nature Reviews Neuroscience article, there is little doubt that leading a sedentary life is bad for our cognitive health. Cardiovascular exercise seems to have a positive effect.
Second, Maintain Lifelong Intellectual Engagement. There is abundant prospective observational research showing that doing more mentally stimulating activities reduces the risk of developing Alzheimer’s symptoms.
Let me add, given all media hype, that no “brain game” in particular has been shown to have a long-term impact on Alzheimer’s or the maintenance of cognition across extended periods of time. It is too early for that-and consumers should be aware of that fact. It is true that some companies are being more science-based than others but, in my view, the consumer-oriented field is growing faster than the research is.
Ideally, combine both physical and mental stimulation along with social interactions. Why not take a good walk with friends to discuss a book? We lead very busy lives, so the more integrated and interesting activities are, the more likely we will do them.
