Prospective memory (PM) is the ability to remember to produce an action at a specific moment in the future signaled by the occurrence of a specific event (event-based [EB] condition), a time or a time interval (time-based [TB] condition). Detection of the appropriate moment corresponds to the prospective component, while production of the appropriate action corresponds to the retrospective component. Although PM difficulties have been reported in healthy aging and in association with multiple sclerosis (MS), PM has not been examined in older persons with MS (PwMS). The main objective of this study was to investigate whether the decline in PM performance with advancing age is influenced by the presence of MS. This study also aimed to clarify the type of PM impairment (prospective vs. retrospective component in TB and EB conditions) in MS as a function of age.

使用前瞻记忆的生态测试研究多发性硬化症和衰老对前瞻记忆的影响。

前瞻性记忆 (PM) 是记住在未来特定时刻采取行动的能力，该行动的信号是特定事件（基于事件的 [EB] 条件）、时间或时间间隔（基于时间的 [EB] 条件）的发生。 TB]条件）。适当时刻的检测对应于预期成分，而适当动作的产生对应于回顾性成分。尽管有报道称 PM 困难与健康老龄化有关并且与多发性硬化症 (MS) 相关，但尚未对患有 MS (PwMS) 的老年人进行 PM 检查。本研究的主要目的是调查 PM 表现随年龄增长而下降是否受到 MS 的影响。本研究还旨在阐明 MS 中 PM 损伤的类型（结核病和 EB 疾病中的前瞻性与回顾性成分）与年龄的关系。
