It was a big week for Alzheimer's disease， and not just because PBS aired
The Forgetting， a first-rate documentary about Alzheimer's worth catching in
reruns if you missed it the first time. There was also a flurry of scientific
news that offered hope to the families already struggling with Alzheimer's， as
well as to the baby-boom generation that's up next. Unless something dramatic
happens， the number of Americans living with this terrifying brain disease could
triple， to about 16 million， over the next 50 years. There's still no cure in
sight， but there is progress on several fronts. Among them：
MEGADOSE VITAMINS Doctors knew vitamins E and C， both antioxidants， help
stave off Alzheimer's， at least in folks who haven't already developed the
disorder. What they didn't know——but a big study involving 4，740 participants
published in the Archives of Neurology showed——was that the two vitamins taken
together in huge daily doses (at least 400 IU of E and more than 500 mg of C)
could reduce the risk of Alzheimer's a remarkable 78%.
COMBINATION THERAPY A yearlong study of more than 400 Alzheimer's patients
showed that two drugs that work differently on the brain's chemistry act well
together to help slow down the disease. Patients who were being treated with
donepezil (sold as Aricept)， an older drug that preserves the neurotransmitter
acetylcholine， were also given memantine (Namenda)， a new drug approved by the
FDA last October that blocks overproduction of a harmful brain chemical called
glutamate. The two drugs worked even better in combination than they did alone，
providing substantial benefit for patients with moderate to severe Alzheimer's，
according to a report in the Journal of the American Medical Association.
BRAIN IMAGING Finally， scientists at the University of Pittsburgh announced
that they had successfully developed a procedure that allows them to peer into
the brains of Alzheimer's patients with positron emission tomography (PET) scans
to see telltale plaque deposits. Before now， doctors could not track the
progress of these plaques until after the patient died， when the brain could be
autopsied. Using the new technique， doctors may be able to begin treatment long
before the first symptoms appear.
None of these advances is a magic bullet for Alzheimer's disease. If you or
your loved ones are concerned， the first step is careful evaluation by your
doctor. Not all memory lapses are Alzheimer's， and there are reversible causes
of forgetfulness that can be treated if caught early. Also， remember the old
adage “use it or lose it.” Mental exercise——reading， doing crossword puzzles，
playing chess or Scrabble——is as good for preserving your mind as physical
exercise is for your body.

1. From the first paragraph， we learn that_________.
the baby-boom generation will not suffer from Alzhemer‘s disease
recent progress brings hope for Alzheimer victims
the week was very important for Alzheimer‘s because a documentary about
it was shown on PBS
the new achievements made on several fronts show that Alzheimer‘s
disease can be cured
2. The phrase “stave off” (line 1， paragraph 2) most probably means
“________”。
getting
treating
curing
preventing
3. The report in the Journal of the American Medical Association shows that
____________.
combination therapy refers to combining two different ways of
treatment
donepezil helps blocks overproduction of a harmful brain chemical
called glutamate
combination therapy is of great benefit to all patients with
Alzheimer‘s
Aricept and Namenda have better effect when used together than used
separately
4. Why is brain imaging considered progress in treating Alzhemer‘s?
Because it helps doctors diagnose and treat the disease in an early
phase by tracking the progress of plaques in the brain.
Because it helps doctors autopsy the brains of the patients after they
died.
Because it helps doctors see the plaque desposits clearly so that they
can operate on the brain.
Because it helps doctors develop a new procedure of tracking the
progress of the disease.
5. To which of the following is the author likely to agree?
Alzhemer‘s disease can be cured thanks to the new advances.
Forgetfulness can be cured by doing mental exercise.
Careful evaluation is important because it can tell Alzheimer‘s from
curable memory lapses， which can be treated if found in an early phase.
Mental exercises do good only to forgetfulness caused by reversible
causes.
