Researchers Discover New Approach to Alzheimer's

The steady erosion of declarative memory is one common symptom of Alzheimer's. People need this part of memory to recall faces, places and facts. Now a group of researchers at Mount Sinai are reporting in Nature that they've found a molecule--IGF-II--that can amp up that particular segment of memory, pointing the way to a potentially effective treatment for dementia.

Tested in rats, the scientists say that they were able to either improve their memory with the molecule or make it worse by inhibiting IGF-II. As the molecul
