Frequent lapses in memory and judgment are not always the first signs of Alzheimer’s disease. New research suggests problems in the way older people walk may provide the earliest reliable clues that they may be suffering from advance stages of dementia.
A new analysis of studies, led by researchers at the
Albert Einstein College of Medicine of Yeshiva
University and Montefiore Medical Center, has found that
seniors whose walking pace begins to slow noticeably and
who also have cognitive impairments are more than twice
as likely to develop dementia within 12 years.
In an exclusive interview on Newsmax TV’s Meet the
Doctors program, lead researcher Joe Verghese ,
M.D., says that combination of symptoms may indicate how
well seniors’ brains are aging and functioning, and
could provide a simple new way for doctors to identify
seniors at risk for Alzheimer’s.
That, in turn, could speed treatment, which is most
effective in combatting and slowing the advance of
dementia when begun early.

“Many years ago when I was a researcher working in an
aging study I examined hundreds of older people and one
of the thing I noticed is that all the people were
walking slowly. When I looked that their cognitive tests
[and] memory tests, I noticed that they were abnormal
too,” says Dr. Verghese, who heads up the Center for the
Aging Brain and the Department of Geriatrics at
Einstein’s Montefiore Headache Center in New York.
“So this gave me an idea that maybe we could use a
simple sign, such as walking, [to] predict who would be
at risk for dementia. Walking is quite a complex
activity so while clearly most people slow down when
they age due to problems like arthritis you need your
brain to function well in order to walk well … And that
slowing of walking that occurs very early might be an
early sign of dementias like Alzheimer’s.”
The findings, published in Neurology, a journal
of the American Academy of Neurology, are among the
latest to develop an easy, affordable way to diagnose
dementia, which is best treated when therapy begins
early. Other research has identified connections between
dementia and sleep disorders, changes in vision and
sense of smell, and abnormal proteins — known as amyloid
and tau — in the brain.
Alzheimer's is the most common cause of dementia. More
than 5 million Americans have been diagnosed with it,
and that figure is expected to double by 2050 as the
U.S. population ages.
“One of the biggest challenges facing us now is that
there’s a growing aging population and there are many
people at risk for developing Alzheimer’s and other
dementias,” says Dr. Verghese.
“And one of the challenges is to find ways to diagnose these people as early as possible before they actually meet criteria for Alzheimer’s so that you can institute preventive measures.
“And one of the challenges is to find ways to diagnose these people as early as possible before they actually meet criteria for Alzheimer’s so that you can institute preventive measures.
”One of the problems with the current diagnostic methods
[is] they aren’t easily accessible. They require either
detailed cognitive testing or they you need to do
neuro-imaging studies.”
He explains that walking “is quite a complex activity”
that requires a well-functioning brain.
“So that slowing of walking that occurs very early might
be an early sign of dementias like Alzheimer’s,” he
says. “Slow gait [can be] caused by poor circulation to
the brain [which may be] the earliest stages of
Alzheimer’s disease.
He also notes there is no cure for Alzheimer’s, but a
number of medications that help with the symptoms.
“The reassuring part is that if I can identify somebody
early I could actually do something to alter the course
of the disease,” he says. “If you think either you or
one of your loved one is walking slow and also you’re
noticing memory complaints or difficulty functioning in
daily life, this is someone you should bring to the
attention of your physician and get them checked out.”
