结局指标
主要结局
Change From Baseline to Month 18 in Alzheimer´s Disease Cooperative Study (ADCS)-Activities of Daily Living (ADL) Inventory
时间窗: Baseline to 9 Months (actual time frame)
The ADCS-ADL scale is a validated tool to assess instrumental and basic activities of daily living based on a 23 item structured interview of the caregiver or qualified study partner. Scores on the ADCS-ADL range from 0-78 with lower scores indicating greater impairment; hence decreases from baseline reflect potential functional deterioration.
Change From Baseline to Month 18 in Cognitive Subscale of the Alzheimer´s Disease Assessment Scale (ADAS-Cog)
时间窗: Baseline to 9 Months (actual time frame)
The ADAS-Cog is a validated psychometric instrument that evaluates memory (word recall, word recognition), attention, reasoning (following commands), language (naming, comprehension), orientation, ideational praxis (placing letter in envelope) and constructional praxis (copying geometric designs). This test was administered by experienced raters certified by Alzheimer's Disease Cooperative Study (ADCS) at each site. Scores on the ADAS-Cog range from 0-70 with higher scores indicating greater impairment; hence increases from baseline reflect potential cognitive deterioration.
