Experimental Alzheimer's drug stirs hope after early trials

After a series of prominent failures, there's reason to be hopeful in the search for a drug to slow the progression of Alzheimer's disease. Results of an early trial of an experimental drug showed that it improved cognition and reduced clinical signs of Alzheimer's in the brains of study participants, and experts are "cautiously optimistic" that the results will be duplicated in future clinical trials.
