ABSTRACT
BACKGROUND:
Subjective cognitive decline (SCD) has been called the prodromal stage of amnestic mild cognitive impairment (aMCI); however, further investigation is needed to confirm this observation.OBJECTIVE:
To define the relationship between SCD and aMCI.METHOD:
In this case-control study, we used the feeling-of-knowing in episodic memory (FOK-EM) test to measure the memory-monitoring function of 40 adults with aMCI, 60 with SCD, and 55 healthy controls.RESULTS:
The recognition rates of FOK-EM (53.53% ± 7.82%; 55.12% ± 6.08%) and judgment accuracy of the aMCI and SCD groups (γ values 0.21 ± 0.11; 0.30 ± 0.16) were significantly lower than those of the control group (72.32% ± 5.14%; 0.57 ± 0.16) (F = 116.24, P < 0.01; F = 128.57, P < 0.01; F = 73.33, P < 0.01). The scores for correct decision/correct recognition (RR; 27.2 ± 6.43; 29.36 ± 5.16) and correct decision/false recognition (RF; 30.41 ± 5.06; 27.26 ± 4.37) of the aMCI and SCD groups were also significantly lower than those of the control group (49.35 ± 7.13; 11.16 ± 4.35) (FRR = 132.67, P < 0.01; FRF = 131.8, P < 0.01).CONCLUSION:
Mild clinical impairments in memory-monitoring function may precede clinically confirmed objective memory impairment in individuals with SCD.
