For most cognitive tests, there is no evidence-based guidance for how much change is ‘normal’ over a given timeframe. This study aimed to statistically determine the limits of clinically-significant memory change among healthy older adults and those with mild cognitive impairment (MCI). Methods: Longitudinal cognitive performance was examined in 21 healthy older adults and 81 individuals with clinically-defined MCI. Participants were assessed on Cantab Paired Associate Learning (PAL), a non-verbal episodic memory test, at baseline, 10 months and 20 months as part of a comprehensive neuropsychological assessment. They were classified as amnestic-MCI if there was a deficit (performance |
