Description
Alzheimer's disease affects a large number of Americans every year, and research on the causes and possible prevention continues to increase. Alzheimer's disease is a form of dementia that causes problems with memory, thinking, and behavior and is thought to be caused by beta-amyloid plaques that form in the brain. In recent years, dogs have been used more and more as an animal model looking at Alzheimer's disease and cognitive dysfunction. Dogs serve as a reliable animal model because effected dogs naturally form the same beta-amyloid plaques that affected humans do as they age. Previous research has shown that older dogs perform worse on various memory tasks than do younger dogs, however researchers have struggled to find a test for dog cognitive dysfunction that is brief and can be performed in the home. The current study aimed to find a brief memory task that requires few materials, but is still reliable. The results of this study do not support the hypothesis that older dogs would perform worse than younger dogs if tested to find a treat with varying time delays of 15, 30, and 45 seconds. The results of this experiment showed a main effect of age (F = 8.40, d.f. 1, 19, p < 0.01) and delay (F = 15.14, d.f. 2, 30, p < 0.01), but age-delay interaction was not significant (F = 2.53, d.f. 2, 30, p = 0.09). Future studies should be performed using a larger sample size and this same protocol to attempt to raise the participation level of the dogs.
