Some Recovery of Memory May Be Possible, Study Finds

WASHINGTON -- While a breakthrough for humans could be years away, a new study in mice suggests some memory recovery may be possible in the early stages of Alzheimer's disease.
"There basically are two prongs and we need to deal with both," said lead researcher Karen Ashe, a University of Minnesota neurologist. "What we're showing is that there are neurons which are affected (by Alzheimer's) but not dead."
New research shows a mutant protein named tau is poisoning brain cells, and that blocking its production may allow some of those sick neurons to recover.
It worked in demented mice who, to the scientists' surprise, fairly rapidly regained memory.
There are no drugs yet to block tau, and most of the recent search for Alzheimer's treatments has focused instead on another protein, called beta-amyloid.
