A new approach to licking Alzheimer's

Man's best friend might prove an unexpected ally in the fight against Alzheimer's.

The disease affects more than 5 million Americans — and that number is expected to more than triple by 2050. Researchers at Arizona State University's Canine Science Collaboratory, led by professor Clive Wynne of the Department of Psychology, are studying dog memory and the effects of an Alzheimer's-like disease, canine cognitive dysfunction, with a maze and lots of treats.

The Office of Knowledge Enterprise Development visited the lab to see the dogs in action.
