D. Researchers Strive to Better Understand All Forms of Alzheimer's Disease

Narrator: This is Science Today. Researchers at the University of California, Irvine have discovered a key protein that may help stave off an inherited form of Alzheimer's disease. Neurobiologist Frank LaFerla says even though this particular form of Alzheimer's disease is rare, they hope their findings may eventually lead to a better understanding of all forms of the disease.

LaFerla: The point is that there are a lot of different strategies that people are using to treat Alzheimer's Disease. Probably no one strategy in and of itself will work - especially considering the multiple forms of Alzheimer's that exist - that probably a combination of therapies are going to eventually be needed as some kind of cocktail.

Narrator: When it comes to science, researchers often times don't know where the next fruitful lead will come from, so LaFerla and his colleagues will continue pursuing the protein link related to an inherited form of Alzheimer's disease.

LaFerla: It may very well be that this is insignificant and have absolutely no therapeutic benefit and in the worse case scenario, might actually make things worse. But you just don't know - you just have to follow these kinds of leads.
