(CNN) ? Scientists say they ?serendipitously? discovered that a drug used to treat a type of cancer quickly reversed Alzheimer?s disease in mice.
?It?s really exciting,? said Maria Carrillo, senior director for medical and scientific relations for the Alzheimer?s Association. ?They saw very positive and robust behavior effects in the mice.?
In the study, researchers at Case Western Reserve University School of Medicine gave mice mega-doses of bexarotene, a drug used to treat a type of skin cancer called cutaneous T-cell lymphoma. Within 72 hours, the mice showed dramatic improvements in memory and more than 50% of amyloid plaque ? a hallmark of Alzheimer?s disease ? had been removed from the brain.
The study was published Thursday in the journal Science.
Gary Landreth, the lead researcher at Case Western, cautioned that even though his results were impressive in mice, it may turn out not to work in people.
?I want to say as loudly and clearly as possible that this was a study in mice, not in humans,? he said. ?We?ve fixed Alzheimer?s in mice lots of times, so we need to move forward expeditiously but cautiously.?
