Poll Question: Do we need better tests for cognitive impairment?
Dementia was diagnosed based mainly on cognitive tests, especially at the mild stage or mild cognitive impairment (MCI). The fact that many clinical trials failed in the treatment of MCI implies that ADAS-Cog maybe not a proper measurement for the MCI stage, though it does show its usefulness in AD treatment. Or the failures may imply that the MCI diagnosed may not a true MCI.
