The Choice Reaction Time is a computerized attention test that evaluates the reaction time and the number of errors by showing patients one card on the computer screen and making them find the same one among similar four cards. The test is performed a total of 12 times.

Population: Intention-to-Treat analysis set.

The Alzheimer's disease Assessment Scale-Cognitive subscale (ADAS-Cog) is an instrument used to assess cognitive dysfunction in individuals with Alzheimer disease and other dementias. It consists of 11 items, with scores ranging from 1 to 70. Maximum score is 70. Higher scores indicate worsening.

Population: Intention-to-Treat analysis set.

DAD-K is the Korean version of the Assessment for Dementia Scale, a tool developed to evaluate the Alzheimer patients' function including both basic and instrumental Activities of Daily Livings (ADL). It evaluates one function from various perspectives including behavior initiation, plan and preparation, and valid performance. It consists of 10 questions, each can score either 0 (no) or 1 (yes), if not applicable, patient will check on "not applicable (x)" which will not count in the calculation. Scores range from 0 to 100. Higher score represents better function

Population: Intention-to-Treat analysis set.

The Seoul-Instrumental Activities of Daily Living (S-IADL) assesses patients' abilities to perform instrumental and social activities of daily living. These include the ability to prepare a balanced meal, remember appointments, keep financial records, remember to take medication, and so on. It is composed of 15 items, with scores ranging from 0 to 45. Lower scores indicate better functioning.
