The CMAI was used to assess the frequency of manifestations of agitated behaviors in elderly participants. It consists of 29 agitated items rated on a 7-point scale of frequency: 1, never; 2, less than once a week; 3, once or twice a week; 4, several times a week; 5, once or twice a day; 6, several times a day; 7, several times an hour. The CMAI total score ranges from 29 to 203. Higher scores indicate worsening of the condition. Negative change from baseline indicates improvement. Mixed Model Repeated Measures (MMRM) was used for the analysis.

The mADCS-CGIC-Agitation is a modified version of the ADCS-CGIC containing additional questions related to agitation and an assessment of the Clinician's Impression of Change focused specifically on agitation. Participants are asked to rate their impression of change as: 1=Marked Improvement; 2=Moderate Improvement; 3=Minimal Improvement; 4=No Change; 5=Minimal Worsening; 6=Moderate Worsening; 7=Marked Worsening. Higher scores indicate worsening of agitation and positive change from baseline indicates worsening. MMRM was used for the analysis.

The NPI is a retrospective caregiver-informant interview covering 12 neuropsychiatric symptom domains. The Agitation/Aggression domain is designed to collect information on the behavioral aspects of agitation/aggression in participants with probable AD and clinically meaningful agitation secondary to AD. Each NPI domain is rated by the caregiver for symptom frequency and severity. Symptom frequency is rated as:1, occasionally; 2, often; 3, frequently; 4, very frequently. Symptom severity is rated as: 1, mild; 2, moderate; 3, severe. The total domain score is calculated as the frequency score multiplied by the severity score and thus ranges from 1 to 12. Higher scores indicate worsening symptoms. Negative change from baseline indicates improvement in symptoms. MMRM was used for the analysis.

The ZBI is a 22-item scale used to assess the impact of a participants' disabilities on the caregiver's life. It is designed to reflect the burden experienced by caregivers of dementia participants and can either be completed by the caregiver or administered as an interview. Each item of the scale is rated to reflect the burden using the 5-point scale: 0=Never; 1=Rarely; 2=Sometimes; 3=Quite Frequently; 4=Nearly Always. The ZBI is scored by summing the responses of the individual questions and ranges from 0 to 88. Higher scores indicate greater caregiver distress. Negative change from baseline indicates less distress. MMRM was used for the analysis.

NPI evaluates both frequency and severity of 12 neuropsychiatric disturbances including delusions, hallucinations, agitation/aggression, depression/dysphoria, anxiety, elation/euphoria, apathy/indifference, disinhibition, irritability/lability, motor disturbance, night time behaviors, as well as appetite/eating. Total domain score= frequency x severity and thus ranges from 1 to 12. NPI domain is rated by caregiver for symptom frequency and severity. Frequency is rated as:1=occasionally, 2=often, 3= frequently, and 4=very frequently. Severity is rated as:1=mild,2=moderate,3=severe. Frequency and severity rating scales has defined anchor points to enhance reliability of caregiver responses. Caregiver distress is rated for each positive neuropsychiatric symptom using following anchored scores. It is rated as 0=not at all,1=minimal,2=mild,3=moderate,4=severe,5=very severe. Individual Item scores are added to yield a possible total score of 0 to 144. MMRM was used for the analysis.

The DEMQOL scale is used to evaluate health-related QOL in participants with dementia and their caregivers. There are 2 versions of the DEMQOL: a 28-item version (rated by the participant); and a 31-item version (DEMQOL-proxy, rated by the caregiver). Both versions are recommended for evaluating participants (and their caregivers) with mild to moderate dementia. The DEMQOL total score ranges from 28 to 112. The DEMQOL-proxy is used for participants with severe dementia; the total score ranges from 31 to 124. For both versions, higher scores indicate greater QOL. MMRM was used for the analysis.

The CSDD scale is used to assess signs/symptoms of major depression in participants with dementia. CSDD has 19 items, and each item is rated for severity on the following scale of 0 to 2 (0 =absent, 1= mild/intermittent 2=severe). CSDD score is calculated by summing non-missing scores from each item score. The scale ranges from 0 (no depression) to 38 (maximum depression). Scores above 10 indicate a probable major depression, above 18 indicate a definite major depression, and below 6 as a rule are associated with the absence of significant depressive symptoms. Higher score indicated maximum depression. MMRM was used for the analysis.
