How is research helping solve the mystery of Alzheimer's?
Scientific research is the key both to finding a cure for Alzheimer's
and to helping the millions already affected by this devastating
disease. Understanding what triggers the disease in some people
is critical to the development of truly effective therapies that
arrest its development or prevent it altogether. The research that
is being done today provides hope that future generations might
be spared the scourge of Alzheimer's disease.

What are the primary areas of Alzheimer's research?
Scientific research about Alzheimer's can be broadly categorized into five general areas:
- Research about possible causes,
which includes the identification of risk
factors for Alzheimer's and the clarification of the underlying
biological processes
associated with the disease;
- Research aimed at improving early
diagnosis of Alzheimer's, including the identification of
cognitive and
biological "markers"
(or tell-tale signs) for the disease and the use of brain-imaging
techniques to identify brain changes even before symptoms
are present;
- Research to develop new treatments,
including medications that target the underlying biological changes
(or pathology) in the brain, and nonpharmacological approaches
to managing behavioral symptoms;
- Research focused on prevention,
which includes understanding whether certain drugs or lifestyle
factors may exert a protective effect against Alzheimer's;
- Research about caregiving,
including what types of educational programs are most effective
and what types of support are most useful.

What have we learned already?
Though ancient writings suggest that Alzheimer's has been around since the
dawn of civilization, scientists have only begun to unravel the mysteries of
the disease. The last few decades have seen an explosion in scientific knowledge,
laying the foundation for medical breakthroughs that will eventually lead to
a cure.
Every day that passes, scientists are learning more about what causes Alzheimer's,
what happens to the brain as the disease progresses, and what can be done to
help prevent it, diagnose it, care for those suffering with it, and ultimately,
to cure it. Exciting new insights about disease processes, most notably regarding
the role of the protein beta amyloid, have driven drug development to
a frenzied pace. Today, dozens of possible new drugs are being tested and scientists
are working hard to develop a safe beta amyloid vaccine that would harness the
body's own immune defenses to fight Alzheimer's. These efforts raise hope that
truly effective treatments - ones that target the root cause of the disease
- may soon be available.
As the race to develop new Alzheimer's drugs continues, progress has also been
made in improving early diagnosis and predicting who is at high risk for Alzheimer's
to enable treatment early in the course of the disease. A significant research
effort, spearheaded by the National Institute on Aging, is also focused on preventing
Alzheimer's, rigorously testing several different interventions that early studies
have suggested may be protective against the disease (for example, estrogen,
nonsteroidal anti-inflammatory drugs, and cholesterol-lowering drugs called
statins). In addition, a growing body of research is driving a better
understanding of the challenges and stresses encountered by caregivers of people
with Alzheimer's and the development of more effective research-based interventions
to ease these burdens.

Why is it important to continue to fund research about Alzheimer's?
Today, an estimated five million* Americans and their families suffer the devastation
of Alzheimer's disease. By 2050, that number is expected to climb as high as
16 million, unless something is done to delay or prevent the onset of the disease.
Direct medical costs associated with Alzheimer's are now estimated to exceed
$250 billion each year, a number that increases exponentially when indirect
costs, such as lost productivity and wages, are included. In 50 years, these
costs will be even more astronomical, potentially bankrupting the entire healthcare
system.
Compare those costs to the $971 million the U.S. Congress appropriated in 2003
to the entire National Institute on Aging, only a portion of which is earmarked
for Alzheimer's research. That's only a tiny fraction of the disease's annual
cost.
Scientific research offers the best hope for helping those who suffer from
Alzheimer's today, and for sparing future generations from this scourge. Public
support for research on Alzheimer's is critical to ensure that generous government
funding continues via the National Institutes of Health. As with any disease,
however, government-funded research alone cannot solve all the puzzles or answer
all the unresolved questions about Alzheimer's disease. Private sources of funding
must fill these gaps. That is why the Fisher Center for Alzheimer's Research
Foundation was established. Through scientific discovery comes hope for a solution
to Alzheimer's.

How can I help support research about Alzheimer's?
There are a number of things you can do to support Alzheimer's research to
help ensure that the promise of scientific discovery is fulfilled. For example,
write to your Congressional representatives to ask them to be involved in the
problem of brain disorders. If you're caring for someone who has Alzheimer's,
consider participating in a clinical trial for caregivers, or involving your
loved one in studies that test new treatments or track the natural course of
the disease. Such studies provide the answers needed to find a solution to Alzheimer's.
Contributing to the Fisher Center for Alzheimer's
Research Foundation is another way that you can help. The Fisher
Foundation funds important research aimed at identifying the
Cause of Alzheimer's, ensuring optimal Care
of those affected, and finding a Cure for this dreadful disease.
In 1995, the Foundation established the Fisher Center
for Alzheimer's Research at The Rockefeller University, the
nation's largest, best-equipped and comprehensive research center
devoted to Alzheimer's research. Under the direction of Nobel laureate
Dr. Paul Greengard, the Fisher Center is leading the battle against
Alzheimer's disease and helping find the solutions so desperately
needed. Your contribution to the Fisher Foundation directly supports
this effort.
