Alzheimer’s breakthroughs ‘turn the tide’

Alzheimer’s researchers have announced two major breakthroughs in the past week. The first, via the University of Florida, is a test which uses the smell of peanut butter to detect the early signs of the disease — a cheap and simple idea which could help thousands of people. The second is from the University of Leicester, where scientists have discovered a chemical which, in mice, completely stops degeneration of brain tissue.
