Did you know that physical activity can reduce your risk for memory loss and dementia? I had the chance to speak to ABC’s Let’s Talk Live team about important lifestyle choices that can keep the mind healthy and active. The good news is that you really can teach an old dog new tricks, and those new tricks can stimulate growth of new brain cells. Watch the video and check out the Alzheimer’s Association website for more information about dementia prevention:
Data presented at the International Conference on Alzheimer’s Disease in Honolulu this week indicated that exercise and adequate vitamin D levels could help reduce risk for the disorder. Framingham Heart Study researchers found that risk for dementia was halved in “moderate to heavy exercisers” compared with more sedentary people, while researchers on a separate study found that vitamin D deficiency can greatly increase risk for mental impairment.
Another study found that injecting the compound florbetapir into the brain of patients with dementia and then performing a PET scan could help pinpoint the size and location of plaques.
Researchers also reported that tea consumption was linked to a slower rate of cognitive decline in older adults without cognitive impairment, but there was no dose response and more studies will need to be done to determine a definitive link. (CBS News, Wall Street Journal, Medscape)

I finished a post-abdominoplasty check, with drains and sutures removed. I then began to tell the patient how to slowly increase her activities and exercise.
She smiled and said: “I have to tell you. I got back on the Wii just to walk yesterday. It told me I had lost weight too quickly and that I need to slow down.”
If you follow me on Twitter or read my personal blog, you probably know by now that I bought myself an iPad this week. The main reason I got it is because I’m a sucker for shiny new technology, but I also wanted to see if I could use it to help myself become a little less sedentary.
As I mentioned in my first twoposts about fitness this month, there’s a growing body of research suggesting that a sedentary lifestyle is harmful to your health. I was interviewed about one such study a few months ago on the PRI show “The Takeaway,” and the evidence is fairly convincing: People who spend more hours watching TV also have a higher mortality rate than those who watch it less, even after accounting for exercise. Granted, it’s only a correlation, but the evidence converges quite well with several other studies.
But what am I supposed to do about it? My job requires me to spend long hours in front of a computer screen. If exercising a 30 or 40 minutes a day can’t prevent me from getting heart disease or cancer, what will? Some researchers, including David Dunstan, the lead researcher on the TV-watching study, suggest that just standing periodically, rather than sitting all day, can help a lot. That’s where the iPad comes in. Read more »
As I stutter through recovery from LungMutiny2010, I’m paying more attention to my diet. So as I try to go out for my 10-minute walk everyday, I still drink some sports drink — usually Gatorade made from the massive vat of powder you can buy at Costco.
We tend to get plenty of sodium in our diet — far too much in the U.S. actually — but I always worry about potassium when I’m sweating (Disclaimer: I am not an exercise physiologist or a cardiovascular or nephrology physician.)
I always thought that the widely-sold sports drinks were the best sources of potassium outside of eating bananas or some dried fruits. I was surprised to learn that an 8-ounce serving of orange juice contains 18-fold more potassium than an 8-ounce serving of Gatorade® (450 mg vs. 25 mg). Who knew? Read more »

Healthy VisionTM with Dr. Val: Safe Contact Lens Wear and Care
It’s no secret that doctors are disappointed with the way that the U.S. healthcare system is evolving. Most feel helpless about improving their work conditions or solving technical problems in patient care. Fortunately one young medical student was undeterred by the mountain of disappointment carried by his senior clinician mentors…
I am proud to be a part of the American Resident Project an initiative that promotes the writing of medical students residents and new physicians as they explore ideas for transforming American health care delivery. I recently had the opportunity to interview three of the writing fellows about how to…
I m often asked to do book reviews on my blog and I rarely agree to them. This is because it takes me a long time to read a book and then if I don t enjoy it I figure the author would rather me remain silent than publish my…
When I was in medical school I read Samuel Shem s House Of God as a right of passage. At the time I found it to be a cynical yet eerily accurate portrayal of the underbelly of academic medicine. I gained comfort from its gallows humor and it made me…
I am hesitant to review diet books because they are so often a tangled mess of fact and fiction. Teasing out their truth from falsehood is about as exhausting as delousing a long-haired elementary school student. However after being approached by the authors’ PR agency with the promise of a…
