NCT05749913

Brief Summary

In this study, we develop and validate the " Cognitive Load of Activity Participation Scale" (CLAPs) to measure the frequency and the perceived levels of cognitive load of the elderly participating in various cognitive activities and as a reference for intervention and behavioral Indicators for lifestyle modifications to preventing and delaying dementia.

Outcome Measures

Primary Outcomes (2)

  • The Montreal Cognitive Assessment(MoCA)

    The Montreal Cognitive Assessment (MoCA) is a sensitive tool for screening cognitive function in the early stages of cognitive degeneration.

    10-15 mins

  • Geriatric Depression Scale-Short Form (GDS-S)

    There are 15 questions for elderly in GDS-S used for screening depression state. It takes 5-7 minutes to complete.

    5-7 minutes

Study Arms (4)

Normal

1. Participants living in the community. 2. No vision or hearing impairment. 3. No severe depression, or other neurological/mental disorders affecting cognitive function.

Subjective Cognitive Decline, SCD

1. The Montreal Cognitive Assessment (MoCA) score \>22 2. Use two questions to screen: "Compared with the previous situation, do you have memory problems?", "Has your family or relatives ever thought that you have memory problems compared with the previous situation?", the answer to both questions is yes. 3. Geriatric Depression Scale-Short Form (GDS-S) score \<8

Mild Cognitive Impairment, MCI

1. MCI diagnosed by neurologists or psychiatrists: the diagnosis of MCI is mainly in accordance with the revised consensus version of the diagnostic criteria (Winblad et al., 2004), that is, memory function score is 1.5 standard deviations below the value for age- and education-related norms on the third edition of Wechsler Memory Scale. 2. MoCA: with a range of scores of 17-23(\>17 , \<23) (Trzepacz et al., 2015) 3. Geriatric Depression Scale-Short Form (GDS-S) score \<8

Mild Dementia

1. has met the criteria of dementia 2. at the early stages

  • +6 more criteria

You may not qualify if:
