项目摘要
DESCRIPTION (provided by applicant): The ability to produce the correct words while speaking is critical for normal social, academic and occupational functioning. As word finding or "naming" is mediated by the temporal lobe region, naming difficulty is a common complaint and frequent finding in people with dominant temporal lobe epilepsy (TLE). Naming plays a central role in the clinical care of TLE patients, in that naming performance assists in the determination of lateralization and localization of seizure onset, and identification of cortical areas that are essential for naming is the principle technique for identifying language cortex prior to respective
surgery. Although naming in epilepsy has received considerable attention, these efforts have been restricted to younger adults. The incidence and prevalence of epilepsy is currently highest, and continues to rise, in the elderly. Thus, the absence of information on naming in older adults with epilepsy presents a growing clinical problem, particularly as aging introduces new concerns overlaid upon existent, epilepsy-related naming difficulty. Specifically, naming decline is also a feature of normal aging and a hallmark symptom of Alzheimer's disease. When an older adult with epilepsy presents with word finding decline, we currently lack both the knowledge and the proper tools to determine whether the decline represents a typical age-related trajectory in epilepsy, the beginning of a more severe degenerative process, or the relatively benign effects of normal aging. Importantly, the answer to this question would have a significant impact on diagnosis, follow up and treatment. Unfortunately currently available naming measures have serious limitations that compromise their utility, including assessment restricted to the visual modality, insensitive performance measures, vocabulary confounds and cultural biases. The proposed project will address these problems by: 1) Developing and standardizing age appropriate auditory naming and complementary, visual naming measures for older adults, and 2) Applying these measures to characterize and distinguish among naming patterns in healthy older adults, older adults with epilepsy, and older adults with mild Alzheimer's disease. We anticipate that results will: a) Provide new clinical and research instruments for thorough and effective assessment of naming in older adults, b) Delineate the trajectory of naming across the age span in epilepsy, c) Generate new insights into temporal lobe mediation of word retrieval in the aging brain, and d) Provide a noninvasive protocol to assist in the differential diagnosis of degenerative and non-degenerative disorders that affect higher cortical function in older adults.
描述(由申请人提供):说话时说出正确词语的能力对于正常的社交、学术和职业功能至关重要。由于单词查找或“命名”是由颞叶区域介导的,因此命名困难是显性颞叶癫痫 (TLE) 患者的常见症状和常见症状。命名在 TLE 患者的临床护理中起着核心作用,因为命名表现有助于确定癫痫发作的偏侧化和定位,而命名所必需的皮层区域的识别是在各自的语言皮层之前识别语言皮层的主要技术。
外科手术。尽管癫痫的命名受到了相当多的关注,但这些努力仅限于年轻人。目前,老年人癫痫的发病率和患病率最高,并且还在持续上升。因此,缺乏关于患有癫痫的老年人的命名信息提出了一个日益严重的临床问题,特别是随着年龄的增长,在现有的与癫痫相关的命名困难之上引入了新的担忧。具体来说,命名能力下降也是正常衰老的一个特征,也是阿尔茨海默病的一个标志性症状。当患有癫痫症的老年人出现词汇发现能力下降时,我们目前缺乏知识和适当的工具来确定这种下降是否代表癫痫中典型的与年龄相关的轨迹、更严重的退行性过程的开始,还是正常衰老的相对良性影响。重要的是,这个问题的答案将对诊断、随访和治疗产生重大影响。不幸的是,目前可用的命名方法有严重的局限性,影响了它们的实用性,包括仅限于视觉形态的评估、不敏感的性能测量、词汇混淆和文化偏见。拟议的项目将通过以下方式解决这些问题:1)开发和标准化适合老年人年龄的听觉命名和补充视觉命名措施,2)应用这些措施来表征和区分健康老年人、患有癫痫症的老年人和患有轻度阿尔茨海默病的老年人的命名模式。我们预计这些结果将:a) 提供新的临床和研究工具,用于对老年人的命名进行彻底、有效的评估,b) 描绘癫痫在整个年龄范围内的命名轨迹,c) 对衰老大脑中单词检索的颞叶中介产生新的见解,以及 d) 提供一种非侵入性方案,以协助鉴别诊断影响影响的退行性和非退行性疾病。 老年人的皮质功能较高。
