Scientists at Japan's National Institute for Longevity Sciences are planning to push an oral Alzheimer's vaccine into clinical trials after reporting that the therapy worked in mice. The institute's director, Takeshi Tabira, says that it may be that the therapy only works at the early stage of development in humans. But when tested in mice, the researchers found that the vaccine reduced beta amyloid in the animals genetically modified to develop Alzheimer's and improved their brain function. Mental function returned to near normal levels three months after being treated with a vaccine that spurred their immune system to attack amyloid proteins. No side effects such as bleeding or inflammation was observed. One in five people over the age of 80 suffer from dementia, and most of them have Alzheimer's.
