The Charleston Conference on Alzheimer’s Disease has been featured on the MUSC website!

If you take a philanthropist with a heart to find a cure for Alzheimer’s disease and a physicist with a heart for mentoring young researchers, the likeliest to fast-track such discoveries, the resulting mix is an innovative program called the Charleston Conference on Alzheimer’s disease.

The first one held Feb. 28 – March 2, the very weekend that sequestration went into effect, was a huge success, said Joseph A. Helpern, Ph.D., who organized and chaired the event. The conference tested a new model of funding high-risk, high-reward research to spur basic science research into Alzheimer’s disease as a way to develop collaborative relationships with fellow innovative thinkers to push the frontier in this area.

According to a 2013 report by the Alzheimer’s Association in 2011 new criteria and guidelines for the diagnosis of Alzheimer’s disease were proposed. These changes were suggested, because new research has led to new potential biomarkers. These biomarkers may soon reliably detect brain changes associated with Alzheimer’s disease, especially amyloid beta plaques and neurofibrillary tangles (see my previous post), before symptoms, such as memory problems, are even noticeable. The proposed changes are about two things: 1) three new stages of Alzheimer’s disease and 2) new biomarker tests.

Three proposed stages of Alzheimer’s disease

The first stage, a preclinical or pre-symptomatic stage, is a stage at which pathology in the brain can already be detected before any symptoms (memory loss, language difficulties, etc.) are evident. Think about it this way: supposedly, you’re at risk of developing heart disease, because you have high blood pressure, are obese, have diabetes. What does your doctor recommend? Your doctor suggests treating these symptoms so that you will hopefully never be diagnosed with heart disease in the future. Wouldn’t it be great if it were the same way with Alzheimer’s disease? If we were able to detect those plaques and tangles in thepreclinical stage? If there were a treatment available to reduce, let’s say, the amount of amyloid beta in your brain, wouldn’t this perhaps mean that someday in the future it may be possible to prevent Alzheimer’s disease? Unfortunately, we’re not there yet, but these are exciting times! The second proposed stage is one where mild cognitive changes are apparent – the affected individual would complain about memory changes, and an increase in memory lapses is noticeable to loved ones. But these changes are not so severe yet that activities of daily living (anything from balancing the checkbook to bathing) become very difficult or impossible to do. The third and final stage in then the Alzheimer’s disease stage. Together, these three stages cover the whole continuum of the development of Alzheimer’s disease.

Because we cannot easily check if there are amyloid beta plaques or signs of injured brain cells in the living human brain, biomarkers are currently being developed to see if it is possible to detect these in other, less invasive, ways, for example in a blood sample or in cebrebro-spinal fluid, the fluid that surrounds your brain and spinal cord. The exciting thing is that new neuroimaging tools have been developed that allow one to look for markers of amyloid beta in the living human. One of these techniques, called “Pittsburgh Compound B Imaging” or short “PiBImaging” can visualize a patient’s amyloid burden. The picture shows low levels of amyloid in the healthy brain (Control) shown in cold colors, but large amounts of amyloid in the brain of a patient withAlzheimer’s disease (AD) shown in red and yellow.

So what is the billion dollar question?

The 2013 report from the Alzheimer’s Association (download report here) states that currently an estimated 5.2 million Americans have Alzheimer’s Disease. This number is expected to rise to a whopping 13.8 million by 2050. In terms of economic costs this translates to:

  • 17.5 billion hours of unpaid care primarily by immediate family members thought to be valued at 216 billion dollars
  • 9.1 billion dollars in health care costs in the U.S. for caregivers because of the high physical and emotional impact of caring for someone with Alzheimer’s disease
  • Caregivers‘ lost hours of work due to care-giving
  • 203 billion dollars of payments for health care, long-term care and hospice per year

The billion dollar question of Alzheimer’s disease research is about finding so-called disease-modifying therapies. Targeted at the preclinical stage of Alzheimer’s disease these therapies should be able to prevent and/or reduce the accumulation of amyloid beta plaques and neurofibrillary tangles in the brain long before Alzheimer’s disease is diagnosed. Even if we cannot cure Alzheimer’s disease, if we can at least slow down progression, the huge economic burden placed on society and the physical and emotional burden placed on caregivers could potentially be dramatically reduced.

Why write this story for a blog on exercise and the brain?

In a previous post I already discussed exercise as a potential strategy to reduce the risk of developing Alzheimer’s disease (link). Here, I’m going one step further: could aerobic exercise, when targeted at the preclinical stage, e.g. during midlife, potentially reduce the brain pathology associated with Alzheimer’s disease? While studies on this topic are currently in the planning stage or ongoing , we’re a long way from knowing the answer. Research using animal models of Alzheimer’s disease is promising, however. Most likely, studies will use PiB Imaging in combination with putative biomarkers, structural brain imaging and cognitive testing to figure out the role of exercise as a potential disease-modifying treatment. These are exciting times for Alzheimer’s research and its translation to clinical care. For now though, let’s stay positive, and, most of all, healthy! It’s never too late to start exercising and eat healthy!

After an incredibly successful launch of the Charleston Conferences series (we’ll call it ‘CC’ for less of a tongue-twister) with the inaugural Charleston Conference on Alzheimer’s Disease (or ‘CCAD’, as we’ve shortened it to) at the end of February 2013, we are gearing up for next year… and beyond.

After several months of prepping, we are ready to launch our new and improved website (check it out at http://www.charlestonconferences.org/), which, for now, includes some information about the series, CCAD 2013 and CCAD 2014.  In the future, as we grow, we hope the site will too.

We are also launching our own Charleston Conferences social network, which is currently up and running for past participants of the conference and for those  invited to the 2014 AD conference.  It’s basic now, but again, as we grow, we’re hoping this site and its network will grow with us and be able to serve as a resource for participants in the CC series to have links to their peers in the field all in one place.

Soon to come will also be our forum, where we hope to continue to engage both past participants and those in and out of research in topics pertinent to AD, and, as we expand, other areas of interest.

For now, check back soon for further updates and check back more often for continued updates on all things Charleston, AD, research, scientific funding… and beyond.
