The impact of pathological aging on economic decision-making is significant, as impairments in this domain increase the vulnerability of older adults to financial abuse. Evidence suggests that both Mild Cognitive Impairment (MCI) and Alzheimer's Disease (AD) affect economic decision-making, with healthy older adults outperforming patients and MCI patients demonstrating better performance than AD patients. Financial capacity measures provide more robust findings compared to behavioral tasks, highlighting the need for further research in this area.
The effect of pathological aging on economic decision-making is a topic of major relevance as impairments in this domain place older adults at increased risk for financial abuse. This review aims to characterize decision-making across the continuum that goes from healthy aging to Alzheimer's Dementia. We included 42 studies comparing patients with Mild Cognitive Impairment (MCI) and healthy older adults, patients with Alzheimer's Disease (AD) and healthy older adults, and patients with MCI and patients with AD. Substantial evidence emerged suggesting that both MCI as AD affect economic decision-making. However, a non-negligible number of behavioural tasks failed to find significant differences between patients and controls, and no differences were reported between patients with MCI and AD. On the contrary, measures of financial capacity reached more robust findings, showing that healthy older adults had better performance than patients, while MCI patients showed better performance than AD patients. This review presents the main conclusions that may be drawn from significant findings, as well as the hypotheses and recommendations for future research.
