Abbreviations: EQ‐5D, the European Quality of Life‐5 Dimensions; GDS, Geriatric Depression Scale; IQR, interquartile range; MCI, mild cognitive impairment; NPI‐Q, Neuropsychiatric Inventory Questionnaire; SCD, subjective cognitive decline; VAS, Visual Analogue Scale.

Notes: P‐values were obtained using independent samples t tests or analysis of variance for normally distributed continuous variables (mean [SD]), Mann‐Whitney two sample tests for non‐normally distributed continuous variables (median [IQR]), and chi‐square tests for categorical variables (n [%]).
