Functional profiles of older adults from the dementia continuum: Analyzing critical errors that occurred during an IADL ecological evaluation

Older adults with Alzheimer disease (AD) or mild cognitive impairment (MCI) experience challenges that affect their independence. Instrumental activities of daily living (IADLs) are critical in assessing the independence. Single errors can have considerable impact, as they can lead to institutionalization. Thus, optimal recommendations regarding independence depends on an accurate analysis of IADL, including a fine grain analysis of the type of critical errors. Our study aim to describe the errors produced by older adults from the dementia continuum (AD, MCI and older adults living in the community with no dementia) when performing IADL. More specifically, our objectives are to understand: (1) What are the main types of errors occurring during IADL and (2) When are these errors more likely to occur.
