New Alzheimer’s Drug Slows Memory Loss in Early Trial Results
The long, discouraging quest for a medication that works to
treat Alzheimer’s reached a potentially promising milestone. For the first time
in a large clinical trial, a drug was able to both reduce the plaques in the
brains of patients and slow the progression of dementia. More extensive trials
will be needed to know if the new drug is truly effective.
“This trial shows you can both clear plaque and change
cognition,” said Dr. Reisa Sperling, director of the Centre for Alzheimer Research and Treatment at Brigham and Women’s Hospital in Boston, who was not
involved in the study. “I don’t know that we’ve hit a home run yet. It’s
important not to over-conclude on the data. But as a proof of concept, I feel
like this is very encouraging.”
Aside from a couple of medications that can slow memory
decline for a few months, there is no effective treatment for Alzheimer’s,
which affects about 44 million people worldwide, including 5.5 million
Americans. It is estimated that those numbers will triple by 2050.
