Comparison of time spent and score in digital recognition test and free recall tests in the identification of mild cognitive impairment and Alzheimer disease

Digital memory tests are proposed for the screening of mild cognitive impairment (MCI) and Alzheimer disease (AD). However, previous studies are seldom measuring the time spent of a participant in a memory test. So, it is unclear whether the time spent in a digital memory test can be a predictive factor for the identification of MCI and AD. The objective of this study is to evaluate the diagnostic performance of the digital recognition test, immediate and delayed free recall test in the identification of MCI and AD.
