Primary Outcomes (2)

  • CERAD-K (the Korean Version of the Consortium to Establish a Registry for Alzheimer's Disease)

    CERAD-K includes: Verbal Fluency-number of kinds of animal patients listed per minute, ranges from 0, no maximum point fixed.Boston Naming Test is naming objects (0-15). Mini-Mental State Examination in the Korean version of CERAD Assessment Packet (0-30). Word List Memory (0-30). Construction Praxis is from 0-11. Word List Recall and Word List Recognition ranges from 0-10.Construction Recall (0-11).

    26 weeks

  • CERAD-K

    CERAD-K includes: Trail making test A and B is scored by the time spent to link randomly arranged numbers and alphabets in correct order. Except Trail making test A and B, higher score presents better condition.

    26 weeks
