HealthDay (9/16, Dallas) reports that according to a study published Sept. 14 in the journal Nature Neuroscience and partially funded by the National Institutes of Health, “the human brain may have a way to compensate for the build-up of” beta-amyloid protein, which has been tied to Alzheimer’s. For the study, “22 healthy young adults and 49 older adults who showed no signs of mental decline” underwent functional magnetic resonance imaging scans while they performed a scene memorization exercise. Researchers found that “for people with beta-amyloid deposits in the brain, the more detailed and complex their memory, the more brain activity there was,” as if the brain were trying to compensate for presence of beta-amyloid. 

BBC News (9/15, Mundasad) also covered the study.
