Trial Outcomes & Findings for Treatment With Namenda in Women at Risk for Cognitive Decline (NCT NCT00242632)

NCT ID: NCT00242632

Last Updated: 2017-06-14

Results Overview

This tests verbal memory (word list). A list of words is presented and subjects are asked to recall as many as they can. Then a list of interference words is presented. Finally a recognition list of 44 words is presented where subjects are asked to distinguish between target words and distractors. The mean difference in the percentage of target words recalled between time 1 and time 2 is calculated below.

PRIMARY outcome

Timeframe: 6 months

Population: All participants were grouped together for this Outcome Measure. As per the protocol, the analyses of neuropsychological variables were to be done separately for the ApoE-ɛ4 carriers and non-carriers, only if the ApoE-ε4 status was a significant predictor of change in neuropsychological performance.

Timeframe: 6 months

Population: All participants were grouped together for this Outcome Measure.

The Delis-Kaplan Executive Function System (DKEFS) Verbal Fluency Category Switching test measures letter fluency, category fluency, and category switching. The score is the total number of correct words generated during each of the 60-second trials within the three conditions of the test. The mean difference in the total number of correct words generated between time 1 and time 2 is calculated below.
