did not discuss sensitivity of the TTCC for mild
cognitive impairment (MCI). MCI is classified into several
types, and amnestic MCI (aMCI) is thought to lead to AD.
To prevent AD and implement early intervention, screening
tests are required to selectively detect aMCI. Therefore, the
present study was designed to assess the efficacy of the TTCC
for earlydetectionofAD. Patientswitheither verymildADor
aMCI were enrolled in the study.The symptoms of very mild
ADand aMCI are oftensimilar; thus, we also discusswhether
very mild AD and aMCI can be detected using reversebackward
presentation of figures (an interference task of
TTCC)
