Several validated screening tools exist for mild cognitive impairment. Although the MMSE is probably the most widely used and studied, it takes around 10 minutes to complete. The Mini-Cog takes only 2-3 minutes to complete and has the same sensitivity and specificity as the MMSE. The SLUMS test takes slightly less time to complete (~7 min) and has better sensitivity than the MMSE for mild dementia but is not the most efficient screening tool. Asking the patient their name, where they are, and what date/day it is (person, place, and time) is a method to assess orientation, which is only a part of a screening tool for MCI.
