Using scores obtained from cognitive tests, Johns Hopkins researchers think they have developed a model that could help determine whether memory loss in older adults is benign or a stop on the way to Alzheimer’s disease.
The risk of developing dementia increases markedly when a person is diagnosed with mild cognitive impairment, a noticeable and measurable decline in intellectual abilities that does not seriously interfere with daily life. But physicians have no reliable way to predict which people with mild cognitive impairment are likely to be in the 5 to 10 percent a year who progress to dementia.
