   Handling not-applicable responses in the FAQ: An example of functional activities in AD, VaD and DLB 1. Determine whether functional activity levels differ among Alzheimers  disease (AD), vascular dementia (VaD), and dementia with Lewy bodies (DLB).   2. Examine whether the relationship in aim #1 varies when different approaches  for handling not-applicable responses (to items in the Functional  Activities Questionnaire - FAQ) are used.   3. Provide recommendations for handling not-applicable responses in the  FAQ via simulation studies using NACC data.
