Outcome Measures

Primary Outcome Measures

  1. Total of clinician impression column on anxiety domain of the NPI-C [Continuous, weeks 0-8]

    Measure of Anxiety Domain on the Neuropsychiatric Inventory-Clinician scale

Secondary Outcome Measures

  1. Total score on the Generalized Anxiety Disorder 7 scale [Continuous, week 0-8]

    Secondary Outcome Measure of anxiety reduction

  2. Number of serious adverse events [Continuous, weeks 0-8]

    Secondary Outcome Measure of safety defined by absence of serious adverse events

  3. Week 8 MMSE total score compared to baseline MMSE total score [longitudinal: screening/baseline and week8]

    Secondary Outcome Measure of safety as defined by lack of treatment emergent cognitive impairment as measured by the Mini Mental Status Exam (MMSE)

  4. Score on the confusion assessment method [Continuous screening weeks 0-8, dichotomous]

    Secondary Outcome Measure of safety defined as absence of treatment emergent delirium as measured by the Confusion Assessment Method (CAM)

  5. Number and severity of side effects reported [Continuous, weeks 0-8]

    Secondary Outcome Measure of safety defined as a low number of emergent somatic side effects as measured by the Medication Side Effects Questionnaire

Other Outcome Measures

  1. Total clinical impression column score on neuropsychiatric inventory agitation and aggression domains (NPI-C) [Continuous, weeks 0-8]

    Exploratory measure to see reduction in agitation and aggression symptoms

  2. Total score of Cohen-Mansfield Inventory (CMAI) [Continuous, weeks 0-8]

    Exploratory measure to see reduction in agitation symptoms

  3. Total Score of Zarit Caregiver Burden Interview [Continuous, weeks 0-8]

    Exploratory downstream reduction in caregiver burden

  4. Stability of anxiety and agitation reduction using anxiety domain of NPI-C and GAD-7 [Months 3, 6, 9, and 12 of the optional follow-up phase]

    Exploratory investigation into the stability of anxiety reduction using the anxiety domain score on the NPI-C and the GAD-7 during the optional follow-up phase

  5. Stability of caregiver burden reduction [Months 3, 6, 9, and 12 of the optional follow-up phase]

    Exploratory investigation into reduction of caregiver burden using the Zarit Caregiver Burden Interview during the optional follow-up phase
