Actually, perhaps an effective drug treatment that can prevent the plaque from destroying areas of the brain. From the story:
Biologists have developed a compound which has successfully prevented the disease killing brain cells, improving memory and learning ability that was already damaged.
The researchers at the University of St Andrews, working with scientists in the US, have developed man-made compounds capable of blocking a nerve cell interaction known to lead to the symptoms of the disease.
Of course, there is much work yet to do–including full human trials to test efficacy and safety–and hence years probably before the treatment would be widely available. But this story is only one of many exciting avenues of medical and biotechnological research ongoing that is not controversial. Too often this fact gets lost in the hype and controversy over stem cells.
