Dear ,

Earlier this month, The Hartford insurance company announced a new policyholder benefit: they are making our DriveSharp brain fitness software available to their nearly 2 million AARP customers at a discount. It's part of their Safe Driving for a Lifetime public awareness campaign. What's more, The Hartford will give $50 to members who complete DriveSharp in thanks for making the roads safer for everyone.

We're honored that The Hartford chose Posit Science to partner in this effort. For more information, read the press release or visit The Hartford's website. You can also check out Four Steps to Enhance Your Driving Wellness, a blog post on our site from one of The Hartford's gerontologists and driving experts.

As always, we welcome your feedback. To ask a question or share a thought with Posit Science, please visit our Support Community.

Best regards,

Steven Aldrich CEO

New Study Shows Posit Program Changes Brain and Improves Memory
We're really excited about a new study published by Adam Gazzaley and Anne S. Berry of the University of California at San Francisco. Gazzaley and Berry trained people on Sweep Seeker, one of the exercises in our InSight brain fitness program. They found that people who used Sweep Seeker improved working memory by nearly fifty years, bringing the group with the mean age of 72 equal to a group of 24-year-olds. What's more, EEG results show the training caused physical changes in the brain. Read the press release or the study abstract to learn more.

How to Practice
We've all heard that practice makes perfect, but it turns out how you practice makes a difference. Constantly practicing a single task isn't the best way to go. Instead, you should mix up the task you're trying to master with other tasks. Why? It requires you to think about the task more deeply each time—and that helps your brain remember better. Learn more.

Big Hips Bad for the Brain?
A new study finds a strong correlation between extra weight and poorer cognitive performance in women 65+. What's more: those women with a "pear" shape fared much worse than those with extra belly fat. Why does it matter where the weight is? Find the possible explanation in this BBC article.

Vitamins D and E—Protection against Cognitive Decline
Two recent large-scale studies again suggest brain benefits from vitamins E and D. In one, low blood levels of vitamin D were associated with a higher risk for cognitive decline. The other correlated a vitamin E-rich diet with a lower dementia risk. Learn more about these study results.

While vitamin D is rarely found in large quantities in food (it's the one you get from sunshine), you can increase your vitamin E intake in your diet. We have some great vitamin E-rich recipes in our ThinkFood Brain-Healthy Recipe of the Week program, like Almond Soba Noodles. To see this recipe and sign up for the program, click here!

Better Diagnosis for Brain Injury
Within a few years, a simple blood test might be all it takes to identify a brain injury. That's a great improvement over current methods of diagnosis, which can easily miss or misdiagnose a brain injury, preventing the patient from getting the treatment he or she needs. Why do researchers think blood is the answer to this brain question? Find out.

Dementia in Diabetes Is Different
Diabetes is associated with a higher risk for dementia—but a new study suggests that it's a different type of dementia than in most non-diabetics. Dementia in people with diabetes is more likely to be a result of vascular disease than Alzheimer's. This means that if diabetes is prevented in an individual, dementia might be, too. Learn more.

The Other Brain: From Dementia to Schizophrenia, How New Discoveries about the Brain Are Revolutionizing Medicine and Science (2010)
By R. Douglas Fields

In The Other Brain, R. Douglas Fields turns the spotlight on glia—a group of cells that comprise about 90% of all brain cells. Less well-known than neurons—and once relegated to the role of "helper" to the neuron's dominance—glia come into their own in Fields's work. He draws attention to new research on the critical role of glia in a host of brain functions and failures—from information processing to multiple sclerosis, stroke, and migraines. An enjoyable and informative read, The Other Brain fills an important gap in the understanding of how the brain works. Learn more >>
