They used a ruler to measure the point at which people detected the odor (and to keep the other nostril closed). The weird result: People with a confirmed diagnosis of early-stage Alzheimer's could smell it fine with their right nostril, but not their left, say the UF scientists. Generally speaking, the right nostril picked up on it 10 cm before the left one.[/quote] Impressive. I can't wait to see additional studies that (hopefully) confirm and clarify this potential discovery. Of course, it won't be covered by insurance and hospitals will find a way to turn it into a $10k+ test.
