Abstract：
UNASSIGNED: Memory and affective processing were compared in young adults with a remote mild traumatic brain injury (mTBI), to healthy younger and older adults. We evaluated memory performance when encoding was done under multi-tasking (divided attention) conditions, likely to exacerbate cognitive and psychological symptoms in mTBI.
UNASSIGNED: Participants studied pairs of unrelated words under either full or divided attention conditions. Memory for single words (item memory) and for pairs of words (associative memory) was then assessed in sequential independent recognition tests, under full attention.
UNASSIGNED: Associative memory was poorer than item memory, and worse when encoding was done under divided than full attention. The decline in recognition accuracy from full to divided attention conditions on the associative memory test was significantly greater in mTBI compared to young adults and was similar in magnitude to that observed in older adults under full attention. Self-reported mental and total fatigue increased significantly as performance on the memory tests, following the divided attention condition, decreased, but only in the mTBI group.
UNASSIGNED: Results show lingering memory deficits, and suggest that cognitive tasks may be experienced as psychologically more demanding in those with a mTBI, even months or years after injury.

摘要：
■比较了患有远端轻度创伤性脑损伤（mTBI）的年轻人的记忆和情感处理，健康的年轻人和老年人。我们评估了在多任务（分散注意力）条件下进行编码时的内存性能，可能加剧mTBI的认知和心理症状。
■参与者在完全或分散的注意力条件下研究了不相关的单词对。然后在连续的独立识别测试中评估单个单词（项目记忆）和单词对（联想记忆）的记忆，全神贯注。
■联想记忆比项目记忆差，更糟糕的是，当编码是在分开的情况下完成的，而不是完全关注。与年轻人相比，mTBI在联想记忆测试中从完全注意力到分散注意力的识别准确性下降幅度明显更大，并且与完全注意力下的老年人相似。自我报告的精神和总疲劳随着记忆测试的表现显著增加，在分散注意的条件下，减少,但仅限于mTBI组。
■结果显示记忆缺陷挥之不去，并表明认知任务可能在患有mTBI的人中经历的心理要求更高，甚至在受伤后几个月或几年。
