“Do it yourself” screening tools for dementia have found a ready market in the United States. But the early alert Alzheimer's home screening test raises profound legal and ethical issues—not least the effect the test might have on a consumer public that, because of heightened apprehension about what happens to people with dementia, could be described as a group that is already “vulnerable, bordering on desperate” (Gerontologist 2003;43:292–294).
Everyone experiences and describes pain differently. Using functional magnetic resonance imaging and an established scoring system for rating the intensity of a painful heat stimulus, researchers have confirmed that there's a neural basis for these differences. The levels of brain activity in patients who reported similar pain scores were similar—and the higher the subjective scores, the more neural activity detected in the cerebral cortex (Proceedings of the National Academy of Sciences 2003, www.pnas.org/cgi/doi/10.1073/pnas.1430684100).
