Primary Outcome Measures:
  • Change From Baseline in Mini-mental State Examination (MMSE) Total [ Time Frame: Baseline, Week 52, and Week 52 LOCF ]
    MMSE measured general cognitive functioning: orientation, memory, attention, calculation, language, visuospatial functions. Total score derived from sub-scores; total ranged from 0 - 30, where a higher score indicated better cognitive state.

  • Change From Baseline in Neuropsychiatric Inventory (NPI) Score of Psychiatric Symptoms [ Time Frame: Baseline, Week 52, and Week 52 LOCF ]
    NPI measured 10 different domains of psychiatric symptoms including delusion and hallucination. Each domain is scored for: present or absent, frequency, and severity. The score derived from sub-scores; total ranged from "0" to "120," higher score indicated worse neuropsychiatric outcomes.

Enrollment: 160
