摘要:

文题释义:

轻度认知障碍是介于正常衰老与痴呆的过渡状态,是相对于年龄与教育程度的记忆或其他认知功能减退,记忆力、语言功能、注意力、执行能力等不同认知领域的减退,以记忆力减退为最常见的临床表现。国际轻度认知功能障碍工作组在2003年制定了轻度认知障碍的诊断标准:①有认知主诉,本人或知情者提供的认知功能障碍线索;②有认知功能损害的客观证据,选用蒙特利尔认知评估量表进行评分,高中及以上文化程度者≤26分,初中及以下文化程度者≤25分,且主要表现为记忆项异常者;③日常生活能力正常或仅有复杂日常能力轻度减退;④简易认知状态量表≥24分,不符合精神疾病的诊断和统计手册第四版诊断为痴呆的标准。

语义记忆:包括对词语的意义、概念与事实的记忆。语义记忆涉及概念和实际知识是储存。广义上语义记忆包括对世界的所有认识。严格意义上的语义记忆,则是根据命名、分类任务判定。语义记忆障碍的患者表现为对熟悉的物品命名障碍。轻度的可能表现为语义分类词生成的减少,而严重的语义记忆障碍则表现为告知物品用途也不能进行命名,或给予名称也不能说出物品的用途,严重者可能表现为常识的缺失。

背景:阿尔茨海默病是一种进行性神经系统退化疾病,以认知下降为主要特点。认知力下降会导致老年人逐渐失去自我照料的能力,影响日常生活和活动。轻度认知障碍作为阿尔茨海默病的前驱状态,尽早对轻度认知障碍进行诊断和治疗,对预防阿尔茨海默病发展有重大的意义。

目的:针对轻度认知障碍语义记忆障碍评估与治疗的发展及未来前景做一综述。

方法应用计算机在PubMedWeb of Science和中国知网、万方等数据库检索轻度认知障碍语义记忆评估、治疗的相关研究,检索关键词为“mild cognitive impairmentsemantic memory impairmentsemantic memory deficit,语义记忆,轻度认知功能障碍,轻度认知损害”,检索时间为20091月至201911月。

结果与结论:语义记忆障碍为轻度认知障碍的主要临床症状之一,有一定的特异性。目前有不同类型的记忆量表可作为轻度认知障碍语义记忆障碍的神经心理学测量,颞叶、额叶和前运动区可能参与语义记忆环路。针对性的语义记忆神经生理学及辅助检查,靶向进行语义记忆康复训练,可利于早期识别轻度认知障碍的发生与转化。

Abstract:

BACKGROUND: Alzheimer’s disease is a progressive neurological degenerative disease characterized by cognitive decline. Cognitive decline can make the elderly gradually losing their self-care ability, which eventually affects daily life and activities. Mild cognitive impairment is a precursor state of Alzheimer’s disease, and to diagnose and treat mild cognitive impairment as soon as possible has great significance in preventing the development of Alzheimer’s disease.

OBJECTIVE: To summarize the development and future prospects of the assessment and treatment of semantic memory disorders due to mild cognitive impairment.

METHODS: A computer-based retrieval of PubMed, Web of Science, CNKI, and WanFang was performed for related studies on the evaluation and treatment of mild cognitive impairment in semantic memory. The keywords were “mild cognitive impairment, semantic memory impairment, semantic memory deficit” in English and Chinese, respectively. The retrieval time was from January 2009 to November 2019.

RESULTS AND CONCLUSION: Semantic memory disorder is one of the main clinical symptoms of mild cognitive impairment, and has certain specificity. At present, there are different types of memory scales that can be used as neurophysiological measures of semantic memory disorder due to mild cognitive impairment. The temporal lobe, frontal lobe, and premotor region may participate in the semantic memory loop. Targeted semantic memory neurophysiology and auxiliary examinations, and targeted semantic memory rehabilitation training can be helpful for early identification of the occurrence and transformation of mild cognitive impairment.

Key words: mild cognitive impairment, semantic memory, functional magnetic resonance imaging, semantic ability test, semantic initiation, neuropsychological measurement, repetitive transcranial electrical stimulation, exercise therapy
