Q & A
What is Alzheimer's disease (AD) and how common is it?
-Alzheimer's disease, or AD, is the most common form of dementia, accounting for 60% to 80% of all dementia cases. It is a progressive neurological disorder that affects memory, thinking, and behavior.
How frequently does Alzheimer's disease develop in the United States?
-On average, one person in the United States develops Alzheimer's disease every 66 seconds.
What are some early symptoms of Alzheimer's disease?
-Early symptoms of AD may include increased memory problems, difficulty finding the right words, confusion about time or place, trouble managing money, changes in mood or personality, and misplacing things.
What causes the symptoms of Alzheimer's disease?
-The symptoms of AD arise due to slow, ongoing injury to different parts of the brain, which affects nerve cells. This injury is believed to be the result of two processes involving proteins called amyloid beta and tau.
How does amyloid beta contribute to Alzheimer's disease?
-Amyloid beta (A beta) starts to collect inside the brain, forming plaques that can begin as many as 20 years before the first signs of AD appear. In healthy individuals, A beta is removed by the body, but in those with AD, it clumps together and forms plaques that affect brain regions responsible for learning and memory.
What is the role of tau protein in the development of Alzheimer's disease?
-Tau protein, which normally plays a helpful role in the brain, becomes altered in AD. It forms tangles within nerve cells, contributing to the injury of nerve cells and the progression of the disease.
How can an early diagnosis of Alzheimer's disease potentially benefit patients?
-An early diagnosis of AD can potentially slow the disease's course and may help protect the brain from further injury. It also allows patients to consider participating in clinical studies investigating new treatments.
What diagnostic tools are available to help doctors diagnose Alzheimer's disease in its early stages?
-Diagnostic tools for early-stage AD include lab tests, written tests, interviews, PET CT imaging to spot amyloid plaques, and spinal fluid tests for abnormal levels of amyloid beta and tau.
What are the current treatment options for Alzheimer's disease?
-Currently, the only approved therapies for AD help address some of its more advanced symptoms. There are ongoing efforts to develop treatments that may delay, stop, or prevent the progression of the disease.
How can lifestyle factors contribute to managing Alzheimer's disease?
-A lifestyle that includes a healthy diet, regular exercise, social interaction, and cognitive stimulation may be helpful in managing Alzheimer's disease.
What is being done globally to advance understanding and treatment of Alzheimer's disease?
-A large community of healthcare providers, research scientists, universities, patient advocacy organizations, and pharmaceutical companies are committed to battling Alzheimer's disease. Over 500 clinical studies with many thousands of participants are helping to advance understanding and potential treatments.

many people as they get older may notice
changes in memory and thinking abilities
at first these changes may be so subtle
that they're easy to explain away as
normal aging and they may be
however it's also possible that they're
the earliest symptoms of alzheimer's
disease
alzheimer's disease or ad is the most
common form of dementia and accounts for
sixty percent to eighty percent of all
cases of dementia
in the united states alone it is thought
that one person develops a d every 66
seconds on average
in the early stages people with ad may
notice everyday tasks becoming more
difficult to perform than before
some typical early symptoms of ad you
may notice include
facing increased problems with memory
struggling to find the right words for
things
becoming confused about time or place
having trouble managing money or paying
bills
experiencing changes in mood personality
or judgment
misplacing or being unable to find
things
the symptoms of a d arise because of
slow ongoing injury to different parts
of the brain
this injury which affects nerve cells is
believed to be the result of two
different processes that occur in the
brains of people with ad
one involves a protein called amyloid
beta or a beta and the other involves a
protein named tau
in the first of these processes a beta
starts to collect inside the brain
this may begin as many as 20 years
before the first signs of a.d appear
[Music]
a beta is produced inside the brains of
all people but in healthy people it is
removed by the body before it can cause
harm
in the brains of people with ad a beta
clumps together in bigger and bigger
groups and forms clusters known as
plaques
as time goes on plaques begin to form in
more and more parts of the brain which
are responsible for learning memory and
other tasks
[Music]
the second process involving tau protein
begins about 15 years before the first
signs of a.d appear
town normally plays a helpful role in
the brain however in people with ad
tau becomes altered
and forms tangles within nerve cells
eventually the processes involving a
beta and tau can injure nerve cells
as this injury affects one brain region
after another it leads to the appearance
of symptoms you may recognize
a.d is a disease that progresses over
time leading to worsening symptoms and
can ultimately cause death
however studies suggest that early
diagnosis and intervention could
potentially slow the course of a d and
may help protect the brain from further
injury
furthermore an early diagnosis allows
you to consider participating in a
clinical study investigating new
potential treatments
today there are tools available that
might help doctors diagnose ad in its
early stages including various lab tests
written tests and interviews
to confirm whether you have ad your
doctor may order an imaging study known
as pet ct which can spot a beta plaques
inside the brain
your doctor may also request a procedure
to test a sample of your spinal fluid
for abnormal levels of a beta and tau
spinal fluid is a clear colorless body
fluid found in the brain and spine
currently the only approved therapies
for ad help address some of its more
advanced symptoms
however there are ongoing efforts to
develop treatments that if approved may
delay stop or prevent the progression of
a d
in addition studies suggest that a
lifestyle that includes a healthy diet
regular exercise social interaction and
cognitive stimulation may be helpful
for decades a large and growing
community of healthcare providers
research scientists universities patient
advocacy organizations and
pharmaceutical companies has been
committed to battling this disease and
their efforts yield promising new
discoveries with each passing year
over 500 clinical studies with many
thousands of participants across the
globe are helping to advance our
understanding and potential treatment of
a.d
in the fight against a.d you are not
alone
you
