During the aging process, a decline in ability to perform everyday tasks is commonly observed. This is increasingly so for those with dementia and is a diagnostic requirement. These daily tasks require certain cognitive skills which can be measured by various neuropsychological measures. The purpose of this study is to examine which neuropsychological measures are able to detect various deficits in self-reported activities of daily living (ADL) and instrumental activities of daily living (IADL) in individuals with mild cognitive impairment (MCI) and dementia. It is hypothesized that Trail Making Test– B (TMT-B) would be the most sensitive predictor in functional abilities for IADLs and ADLs in both the dementia and MCI populations. This is a quasi-experimental study using archival data and regression statistical models. The only statistically significant finding was that the TMT-B and Mini Mental Status Exam (MMSE) were predictive of IADL functioning within the MCI group, thus incorporating these measures in neuropsychological batteries is warranted. By knowing this information, neuropsychologists may refine their understanding of the utility of neuropsychological assessment and its relationship to disability, implement early intervention techniques to further preserve cognition, as well as assess the most appropriate environmental supports such as residential placements.
