What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Changes of Visual learning test

    Visual learning test of CNT(Computerized neurocognitive function test) was measured in baseline and 12 week. And changes of result from the test were utilized.

    Measured: 12 weeks

  2. Changes of Visual working memory test

    Visual working memory test of WMT(working memory tasks) was measured in baseline and 12 week. And changes of result from the test were utilized.

    Measured: 12 weeks

  3. Changes of Verbal learning test

    Verbal learning test of CNT(Computerized neurocognitive function test) was measured in baseline and 12 week. And changes of result from the test were utilized.

    Measured: 12 weeks

Secondary outcomes (4)
  1. MoCA-K; Korean Version of the Montreal Cognitive Assessment

    The cognitive function evaluation using the Montreal Cognitive Assessment(MoCA-K) is a total of 8 items, and evaluates cognitive functions such as time / execution power, vocabulary, memory, attention, sentence, abstraction, delayed recall, and orientation.

    Time / execution power's total score is 5 points, vocabulary's total score is 3 points, attention's total score is 3 points, sentence's total score is 3 points, abstraction's total score is 2 points, delayed recall's total score is 5 points, orientation's total score is 6 points. It takes about 10 minutes to complete, and the total score is 30 points and total score make sum score. A score of 23 points or more is regarded as normal. If you have less than 6 years of education, add 1 point.

    Measured: 12 weeks

  2. Changes of Auditory continuous performance test

    Auditory continuous performance test of CNT(Computerized neurocognitive function test) was measured in baseline and 12 week. And changes of result from the test were utilized.

    Measured: 12 weeks

  3. BDNF; Brain-derived neurotrophic factor

    Brain-derived neurotrophic factor(BDNF)(pg/mL) was measured in baseline and 12 week.

    Measured: 12 weeks
