Alzheimer’s disease has been difficult for researchers to study and develop treatments for, due to the lack of species with similar plaques and tangles that characterize the condition. For the first time, the same plaques and tangles have been found in the brains of elderly chimpanzees. However, it is unclear if they cause dementia in the animals. Melissa Edler, postdoctoral fellow in Pharmaceutical Sciences at NEOMED, was recently quoted in New Scientist regarding her opportunity to study the brains of 20 older chimpanzees.
