What does every congressional district have in common? Baby Boomers – the sizable generation of people now in their 50s to 70s. It is well documented that the collective aging of the Boomers will have public health impacts. This includes the impacts of the aging brain. Come and learn what happens to the brain as we get older, what happens when the process goes wrong, and what we can do to strengthen the brain as we age.

The Dana Foundation’s Successful Aging & Your Brain PSA has won a Silver Award in the Digital Health Awards Spring 2017 competition! The video features a 90-second animation with four factors on how to live a brain healthy life. The award was submitted under the Educational Institution section and the Web-based Resource category.

The Digital Health Awards recognizes high-quality health resources for consumers and health professionals. Submissions were judged by a panel of health technology professionals and graded based on content, format, success in reaching the targeted health audience, and overall quality. The awards program is organized by the Health Information Resource Center, a clearinghouse for professionals who work in consumer health fields.

 

Remembering Breakthroughs

A New York Times profile earlier this week on Brenda A. Milner, Sc.D., credited her with changing “the course of brain science for good as a newly minted Ph.D. in the 1950s by identifying the specific brain organ that is crucial to memory formation.”

Milner, a Dana Alliance for Brain Initiatives member, identified the hippocampus and other areas of the brain that process memory while working with Henry Molaison, more commonly known as H.M., who developed amnesia at age 29 from the removal of tissue from both his medial temporal lobes, a surgery that was supposed to alleviate his epilepsy.

With the help of H.M., Milner discovered that memory was processed in the medial temporal lobes, which was why he could no longer form new long-term memories. He was, however, able to learn new tasks, meaning he must remember the actions in another part of the brain. His ability to acquire new skills proved to Milner there are two types of memory that occur in different parts of the brain – explicit memory, which recalls describable details like facts and events, and implicit memory, for unconscious memories such as actions and procedures. Milner described this finding in a 2010 Dana Foundation interview:

I went to the McGill psychology department and borrowed learning tasks to give him [H.M]. I took down a maze task, which I was sure he wouldn’t learn, and he didn’t. It was a nice control test, because he showed absolutely no progress over three days. Then I gave him the mirror drawing task. H.M. did 30 trials over three days and at the end of the last trial, his performance was absolutely perfect. I can still remember him looking at what he had drawn, saying: “This is strange. I thought this would be difficult, but it looks as though I’ve done it rather well.” I was very excited because it showed that he could have this excellent performance without any awareness that the reason he was doing so well was that he had had the chance to practice the task over three days.

When I saw that H.M.  had this beautiful learning of something he had no memory of having acquired, I then speculated that this task, which involved motor learning, depended on a different system in the brain. His surgeon had damaged his medial temporal system, but this was a kind of learning that was unaffected by this operation, so therefore it must involve other structures.

A Tasty Program at the Rubin

The lady has an extraordinary palate, a palate of incredible finesse. She picks up hot ingredients, touches them, and she thinks about this image on the plate. She has the most disciplined execution on a plate that we’ve ever seen. But the palate is where it’s just extraordinary. And honestly, I know chefs with Michelin stars that don’t have palates like hers.                           –Chef Gordon Ramsay, MasterChef judge

Christine Ha’s blindness didn’t stop her from defeating more than 30,000 home cooks to secure the coveted MasterChef title, a $250,000 cash prize, and a cookbook deal. Her extraordinary story caught the attention of the organizers of the Brainwave series at the Rubin Museum of Art in New York City, who invited her to talk to neuroscientist David Linden about the food-brain connection in a program entitled, “How Does a Blind Cook Cook?

Alzheimer’s: Every Minute Counts

In the United States, someone is diagnosed with Alzheimer’s disease every minute; around the world, it’s every four seconds. “It is the biggest epidemic we have in this country,” says Harvard University’s Rudolph Tanzi, “I’m shocked that people aren’t panicked about what this disease is going to do to the country or to their families.”

This Wednesday (January 25) at 10 pm ET, PBS is premiering “Alzheimer’s: Every Minute Counts,” an urgent wake-up call about the national threat posed by the disease. The documentary includes interviews with doctors, caregivers, and longtime researchers of the disease, such as Dana Alliance member Tanzi.
