Abstract

Research suggests that increased financial exploitation vulnerability due to declining decision making may be an early behavioral manifestation of brain changes occurring in preclinical Alzheimer's disease. One of the earliest documented brain changes during the preclinical phase is neurodegeneration in the entorhinal cortex. The objective of the current study was to examine the association between a measure of financial exploitation vulnerability and thickness in the entorhinal cortex in 97 cognitively unimpaired older adults. We also investigated financial exploitation vulnerability associations with frontal regions typically associated with decision making (e.g. dorsolateral and ventromedial prefrontal cortices), and additionally examined the interactive effect of age and cortical thickness on financial exploitation vulnerability. Results showed that greater financial exploitation vulnerability was associated with significantly lower entorhinal cortex thickness. There was a significant interaction between age and entorhinal cortex thickness on financial exploitation vulnerability, whereby lower entorhinal cortex thickness was associated with greater financial exploitation vulnerability in older participants. When the group was divided by age using a median split (70+ and <70 years old), lower entorhinal cortex thickness was associated with greater vulnerability only in the older group. Collectively, these findings suggest that financial exploitation vulnerability may serve as a behavioral manifestation of entorhinal cortex thinning, a phenomenon observed in suboptimal brain aging and preclinical Alzheimer's disease.

认知能力未受损的老年人内侧皮层厚度较低与更易遭受经济剥削有关。
研究表明,由于决策能力下降而导致的经济剥削脆弱性增加,可能是临床前期阿尔茨海默病发生脑部变化的早期行为表现。在临床前期阶段,最早被记录的大脑变化之一是内耳皮层的神经变性。本研究的目的是在 97 名认知能力未受损的老年人中,研究经济剥削脆弱性与内叶皮层厚度之间的关联。我们还研究了金融剥削脆弱性与通常与决策相关的额叶区域(如背外侧和腹侧前额叶皮层)之间的关联,此外还研究了年龄和皮层厚度对金融剥削脆弱性的交互影响。结果表明,更容易受到经济剥削与内侧皮层厚度明显较低有关。年龄和内黑质皮层厚度对金融剥削脆弱性有明显的交互作用,即年龄越大,内黑质皮层厚度越低,金融剥削脆弱性越高。当使用中位数分割法按年龄划分组别时(70 岁以上和

期刊介绍: Cerebral Cortex publishes papers on the development, organization, plasticity, and function of the cerebral cortex, including the hippocampus. Studies with clear relevance to the cerebral cortex, such as the thalamocortical relationship or cortico-subcortical interactions, are also included. The journal is multidisciplinary and covers the large variety of modern neurobiological and neuropsychological techniques, including anatomy, biochemistry, molecular neurobiology, electrophysiology, behavior, artificial intelligence, and theoretical modeling. In addition to research articles, special features such as brief reviews, book reviews, and commentaries are included.
