To identify cognitive predictors of declining financial capacity (FC) in persons with mild cognitive impairment (MCI).
Participants were 66 cognitively normal older adults and 49 persons with MCI who completed neuropsychological testing and a performance measure of financial capacity (Financial Capacity Instrument; FCI) at baseline and two-year follow-up. We calculated two-year change scores for neuropsychological tests and FCI total score. We examined bivariate correlations between demographic/clinical variables and FCI change score, and between neuropsychological and FCI change scores. The five strongest bivariate correlates were entered into a linear regression analysis to identify longitudinal predictors of financial decline within group.
Persons with MCI showed significant decline on the FCI and most cognitive variables, while controls demonstrated relatively stable performance. For persons with MCI, education correlated with FCI change score. The top four cognitive variable-FCI change score correlations were written arithmetic, confrontation naming, immediate visual memory, and visual attention. In the regression model, written arithmetic was the primary predictor and visual memory and visual attention were secondary predictors of two-year FCI change scores.
Semantic arithmetic knowledge, and to a lesser extent visual memory and attention, are key longitudinal cognitive predictors of financial skill decline in individuals with MCI.
Clinicians should consider neurocognitive abilities of written arithmetic, visual memory, and processing speed in their assessments of financial capacity in person with MCI.
确定轻度认知障碍（MCI）患者财务能力（FC）下降的认知预测因素。
参与者包括66名认知正常的老年人和49名MCI患者，他们在基线和两年随访时完成了神经心理学测试以及一项财务能力表现测量（财务能力工具；FCI）。我们计算了神经心理学测试和FCI总分的两年变化分数。我们检查了人口统计学/临床变量与FCI变化分数之间以及神经心理学与FCI变化分数之间的双变量相关性。将五个最强的双变量相关性纳入线性回归分析，以确定组内财务下降的纵向预测因素。
MCI患者在FCI和大多数认知变量上表现出显著下降，而对照组表现相对稳定。对于MCI患者，教育程度与FCI变化分数相关。认知变量与FCI变化分数的前四个相关性分别是书面算术、对名称的反应、即时视觉记忆和视觉注意力。在回归模型中，书面算术是两年FCI变化分数的主要预测因素，视觉记忆和视觉注意力是次要预测因素。
语义算术知识，以及在较小程度上的视觉记忆和注意力，是MCI个体财务技能下降的关键纵向认知预测因素。
临床医生在评估MCI患者的财务能力时，应考虑书面算术、视觉记忆和处理速度的神经认知能力。
