Catching Alzheimer’s Disease
Early
(Ivanhoe Newswire) -- A new
test may be an important tool in
the fight against Alzheimer’s
disease. A study reported in
Clinical Electroencephalography
highlights the use of an
electrical brain test to detect
the disease earlier, which may
lead to improved treatment. The
test, known as an
electrophysiological test,
detects impaired memory, which
is known to precede the disease.
The study involved 1,506
patients who underwent testing.
Researchers found 65 percent of
patients with impaired memory
would have been missed by using
traditional methods of memory
testing. They say the new
method, called P300 latency
testing, was more sensitive at
detecting changes in cerebral
function.
The authors of the study from
New York and the University of
North Texas are confident this
new testing method may be able
to partially reverse
Alzheimer’s. It is well
documented that if Alzheimer’s
is caught early, some
medications can slow the
process. This study is
particularly important because
the number of people aged 60
years and older will increase
from one in 10 currently to one
in six by the year 2050. After
age 60, the incidence of
dementia doubles every five
years. Therefore, detecting and
treating memory loss early could
delay or avoid the onset of
Alzheimer’s. The researchers say
dementia is the fourth-leading
cause of death.
According to the study, the
P300 latency test should be used
as a screening tool. The authors
say it is a 15-minute test that
can easily be added to a medical
visit.
