Primary Outcome Measures:
- Delayed Recall on the Name-Face Association Test at Week 3 (tolterodine ER vs. placebo) - Number of correct responses to the test
Secondary Outcome Measures:
- 1. Cognitive effects of tolterodine ER vs. placebo at Weeks 1 and 2 on Delayed Recall on the Name-Face Association Test - Number of correct responses to the
- test 2. Cognitive effects of tolterodine ER vs. oxybutynin ER and oxybutynin ER vs. placebo at Weeks 1, 2, and 3 on Delayed Recall on the Name-Face
- Association Test - Number of correct responses to the test 3. Other cognitive effects in the following three paired comparisons: tolterodine ER vs. placebo;
- tolterodine ER vs. oxybutynin ER; and oxybutynin ER vs. placebo on: 3a) Delayed Recall Domain (Verbal and Visual) at Weeks 1, 2, and 3: 3a_i) Delayed Recall on
- the First-Last Name Association Test - Number of correct responses to the test 3a_ii) Misplaced Objects Test - Number of correct recalls at the first attempt 3b)
- Immediate Recall Domain at Weeks 1, 2, and 3: 3b_i) Immediate Recall on the Name-Face Association Test - Number of correct responses to the test in the first
- acquisition - Number of correct responses to the test in the second acquisition 3b_ii) Immediate Recall on the First-Last Name Association Test - Number of
- correct responses to the test in the first acquisition - Number of correct responses to the test in the second acquisition 3b_iii) Facial Recognition Test - Number of
- correct responses before first miss - Total correct responses 3c) Visual Attention and Memory Domain at Weeks 1, 2, and 3: 3c_i) Matching-to-Sample Test -
- Throughput (number of correct responses / minute) 3c_ii) Visual Sequence Comparison Test - Throughput (number of correct responses / minute) 3d)
- Psychomotor/Reaction-Time Domain at Weeks 1, 2, and 3: 3d_i) Divided Attention Test (response speed to visual monitoring task alone) - Median response time for
- correct responses (seconds)
