A Study to Show That the Change of Attention Measure is Correlated With the Changes of Caregiver's Burden After Treatment With Galantamine in Patients With Alzheimer's Disease

Study Overview
=================
Brief Summary
-----------------
The purpose of this study is to demonstrate that the change of attention measure is correlated with the changes of caregiver's burden after treatment with galantamine.

Detailed Description
-----------------
This is an open-label (all people know the identity of the intervention), prospective (in which the participants are first identified and then followed forward as time passes), observational (study in which the investigators/ physicians observe the patients and measure their outcomes), multi-center (study conducted at multiple sites) study. The study mainly consists of 2 phases including, the screening phase (14 days before administration of study medication) and treatment phase (16 weeks). In the treatment phase, patients will receive galantamine 8 mg/day for the first 4 weeks and later on the dose will be increased up to 24mg (if tolerable). Safety evaluations will include assessment of adverse events. The total duration of the study will be 18 weeks.

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Change From Baseline at Week 16 in Attention Questionnaire Scores (AQS) | AQS evaluates the attention of participants with dementia and is designed for their caregivers to evaluate the participant's attention directly. It has 15 questions devised to be suitable for cultural characteristics of Korea through the standardization study considering education and gender/culture gap. Each question is scored from 0 to 2 (0=never, 1=occasionally, 2=usually). In questions 1 to 8, the lower participant attention ability rated the higher score (AQS1), In questions 9 to 15, the higher participant attention ability rated the higher score (AQS2). The total score is calculated by the formula: 16-AQS1+AQS2 and the range is from 0 to 30. Higher score means better attention ability of participant. | Baseline (Week 1 [Day 1]), Week 16 | 
| Change From Baseline at Week 16 in Burden Interview (BI) Scores | BI is designed to evaluate subjective stress dementia patients' caregivers experience in relation to caregiving. It has total 22 questions with 4 options each and the calculated scores are from 1 to 88 (0-20 = Little or no burden, 21-40 = Mild to moderate burden, 41-60 = Moderate to severe burden, 61-88 = Severe burden). Higher scores indicate worsening. | Baseline, Week 16 | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Change From Screening at Week 16 in Mini Mental State Exam Scores (MMSE) | MMSC is a brief 30-point questionnaire test that is used for the assessment of dementia patients' cognitive impairment. Evaluation of points are as: 24-30 = No cognitive impairment, 18-23 = Mild cognitive impairment, 0-17 = Severe cognitive impairment. Lower scores indicate worsening. | Baseline, Week 16 |
