Another study encourages keeping your brain active to ward of Alzheimer’s

In a study published earlier this week by the Archives of Neurology, scientists say their results indicate that people who keep their brains active throughout life with cognitively stimulating activities have reduced levels of beta amyloid plaques, one of the hallmark lesions found in the brains of people with Alzheimer’s disease.

I’m particularly excited to talk about this research because it is out of one of our local labs (UC Berkeley and Lawrence Berkeley National Labs) and was supported in part by grants from the Alzheimer’s Association!

The claim

Results from the research suggest that greater participation in cognitively stimulating activities throughout a person’s life, but especially in the early and middle years, appears to be associated with reduced PiB uptake, and thus reduced amyloid accumulation.

Oxygen therapy for Alzheimer’s?

On a recent episode of the Dr. Oz television program, a guest of the show strongly advocated the use of hyperbaric oxygen treatment for Alzheimer’s disease. So, what is hyperbaric oxygen therapy and when is it used?

What we know

Hyperbaric oxygen therapy (HBOT) is breathing 100% oxygen while under increased atmospheric pressure. According to Mayoclinic.com, “hyperbaric oxygen therapy is a well-established treatment for decompression sickness, a hazard of scuba diving. Other conditions treated with hyperbaric oxygen therapy include serious infections, bubbles of air in your blood vessels, and wounds that won’t heal as a result of diabetes or radiation injury.”  Continue reading “Oxygen therapy for Alzheimer’s?” »

Celebrities turn out for Seth Rogen’s Alzheimer’s fundraiser

I am just back from Hilarity for Charity, a fundraising event put on by Seth Rogen and his wife Lauren Miller. Lauren’s mother was diagnosed at the age of 55, when Lauren was just 25 years old. Lauren and Seth organized this event to help raise money for the Alzheimer’s Association and dispel the myth that Alzheimer’s is just an old person’s disease.

“Tonight, we will laugh to forget how sad this disease is,” Lauren says in the program. “But, more importantly, we’ll laugh to remember that changing the destiny of this illness is up to us.” Continue reading “Celebrities turn out for Seth Rogen’s Alzheimer’s fundraiser” »

Under threat: basic cognitive testing and access to Alzheimer’s research results

Who would have thought that the ability of medical personnel to administer cognitive tests for their patients could get them sued?

But, according to a January 4 article in the San Francisco Examiner Doctors fear copyright crackdown on medical procedures, a company that holds the copyright for one such test started to enforce its claim.  The bottom line is that a simple three-minute memory exercise may end up costing more to administer if a question as basic as “what is today’s date?” is part of that copyright.  As one UCSF doctor said in the article, “There is no other way to ask someone ‘what is today’s date?’” Continue reading “Under threat: basic cognitive testing and access to Alzheimer’s research results” »

Is nicotine good for your memory?

We know that smoking is bad for our health, but what about nicotine? A new study looks at the possible positive effect of the nicotine patch on memory and thinking. The study,  published today in Neurology, looked at nicotine (delivered by a patch) in people with mild cognitive impairment (MCI). MCI is the stage between normal aging and dementia when people have mild memory or thinking problems but not severe enough to affect their everyday lives. Previous research has shown that nicotine stimulates receptors in the brain that are important for thinking and memory skills. People with Alzheimer’s disease lose some of these receptors. Continue reading “Is nicotine good for your memory?” »

Does middle age mark the beginning of cognitive decline?

Whenever I speak to audiences about brain health, I ask, “Has anyone noticed any changes in their brain in the last decade or so?” Inevitably everyone – and I mean everyone – over age 50 raises their hands. They laugh and share examples of forgetting names, car keys, even occasionally losing a car (I’ve done all of the above). The 20- and 30-something audience members look on with a mix of disdain and pity. I always imagine them thinking “poor old people…”

Well it turns out that my anecdotal experience appears to match the findings of a new study. We start to experience some cognitive decline around age 45 on. In an article published last week in BMJ (British Medical Journal), researchers found that – contrary to many other studies – cognitive decline can start long before the age of 60. Continue reading “Does middle age mark the beginning of cognitive decline?” »
