| 摘要 |
The present invention provides smell tests (odor identification tests) that are shorter that UPSIT, yet has a statistical sensitivity and specificity equivalent to or better than UPSIT. The odor identification tests of the invention are based on a core set of six odorants, where the six odorants can be selected from the following group of odorants: menthol, clove, leather, strawberry, lilac, pineapple, smoke, soap, natural gas and lemon. The present invention provides odor identification tests that can: (1) discriminate between subjects who are normal and who have a neuropsychiatric condition, cognitive disease or disorder, and/or (2) predict which subjects with mild cognitive disorders will develop various neuropsychiatric conditions or cognitive diseases and disorders. In one embodiment, the test and methods of the invention can provide an early prediction or diagnosis of Alzheimer's disease that is important for patients (including patients who have mild cognitive disorders, such as MCI) and clinicians to make plans for the future and to institute early treatment.
