The Alzheimer World Day only took place a few days ago and we received many suggestions about creating a selection focusing on this important topic. Webicina’s new Alzheimer’s Disease and Web 2.0 collection features relevant and quality social media resources from blogs and podcasts to community sites and Twitter users focusing on Alzheimer’s disease.
Here is my top 10 social media selection for Alzheimer’s disease: Read more »

Barbara Moscowitz, coordinator of geriatric social work for the Geriatric Medicine Unit at Harvard-affiliated Massachusetts General Hospital, spoke to me and about a dozen other Harvard Medical School employees yesterday as part of series of seminars on family life and other issues offered by the school’s human resources department.
Moscowitz’s talk was titled “Dementia and Cognitive Decline (Aging Gracefully).” I was there mainly out of professional interest because I’ve written a couple of articles for the Harvard Health Letter recently about Alzheimer’s and dementia, including a piece in the September 2011 issue about mild cognitive impairment and another in July 2011 about new Alzheimer’s guidelines.
But I also wonder about how my own aging brain is faring (not well, it seems, on some days) and I have an older parent (age 81).
So my curiosity wasn’t entirely work related.

It’s Wednesday, so I would like to tell you about some cool things I learned this past week about the science of how exercise can be used as a treatment for three common ailments.
First, some background about exercise: The great thing about exercising every day that you eat is that this magic potion is not a shot or a pill. It does not involve a doctor burning or squishing anything in your body. There are no HIPAA forms, no insurance pre-certifications, and not even a co-pay. It’s as we say, easy and free. And drum roll please…exercise is active—not passive.
Here’s the Mandrola take on how exercise might treat three specific medical conditions: Read more »

How much vitamin D is enough, and what’s the best way to get your daily dose of the so-called sunshine vitamin? It depends who you ask.
I just attended the latest Forum at the Harvard School of Public Health. The title, “Boosting Vitamin D: Not Enough or Too Much?” was a tip-off that we weren’t going to get a simple take-home message. (Watch a video of the event beginning Wednesday, March 30.)
Some background: Vitamin D isn’t really a vitamin. It’s a hormone. The body makes it when sunlight strikes the skin. This converts a cousin of cholesterol into a substance that ultimately becomes vitamin D. It is best known for helping the digestive system absorb calcium and phosphorus, so it is important for bone health. New research suggests—emphasis on suggests—that vitamin D may also be involved with regulating blood pressure, fighting cancer, and improving the immune system. Read more »

We all know that using a cell phone can stimulate the brain to work a bit harder. “Mr. Skerrett? This is Dr. LeWine’s office. Do you have a minute to talk about your test results?” or “Dad, a bunch of kids are going to Casey’s house after the dance. Can I go?” But a new study published in JAMA is making me wonder what the energy emitted by the phone itself — not just the information it delivers — is doing to my brain.
Here’s the study in a nutshell. Dr. Nora Volkow and her colleagues recruited 47 volunteers to have their brain activity measured twice by a PET scanner. Both times the volunteer had a cell phone strapped to each ear. During one measurement, both phones were turned off. During the other, one phone was turned on but muted so the volunteer didn’t know it was on; the other was left off. Each session lasted about an hour. The scans showed a small increase in the brain’s use of glucose (blood sugar) when the phone was on, but only in parts of the brain close to the antenna.
It was an elegant study. The researchers took pains to anticipate sources of error. They used a control (both phones off) against which to compare the effect of a “live” cell phone. They used cell phones on each ear, one on and one off, to see if the effect was localized. They muted the phone that was on to eliminate the possibility that any brain activation was due to listening to the sound of a voice coming through the phone’s speaker. So the result is probably a real one, not an artifact or measurement error.
What does this brain activation mean? No one really knows. As Dr. Volkow told NPR, “I cannot say if it is bad that they [cell phones] are increasing glucose metabolism, or if it could be good.” Read more »
