主要渐进式语音失语 (PPAOS) 和渐进式语法失语 (PAA) 似乎是临床连续的一部分,而不是不同的实体. 疾病的严重程度和异文主义预测了更快的进展,强调了更新分类的必要性.
科学领域:
- 神经科学是一个神经科学.
- 神经学 神经学
- 语音语言病理学 语言病理学
背景情况:
- 非流利/语法变异性初级渐进性失语症 (nfvPPA) 的分类仍在争论中,关于初级渐进性语音失语症 (PPAOS) 和渐进性语法失语症 (PAA) 是否是不同的或频谱的一部分的不确定性.
- 了解这些疾病的临床和病理相关性对于准确的诊断和预后至关重要.
研究的目的:
- 分析发言,语言和疾病严重程度在患有渐进性运动发言障碍和/或语法障碍的患者.
- 为了确定这种患者队列中是否存在PPAOS和PAA等不同的,不重叠的综合征实体.
- 识别潜在的病因或预后价值的数据驱动的潜在临床维度 (LCD).
主要方法:
- 对98名参与者的综合分析,包括43名尸检确诊的参与者,评估运动言语 (发作障碍,言语无力症 - AOS),语法障碍和疾病严重程度 (临床痴呆症评分总和盒 - CDR-SB).
- 利用集群和主要成分分析来识别症状集群和潜在的临床维度.
- 采用线性混合效应模型来分析纵向疾病进展.
主要成果:
- 只有两个强大的子组被确定,在语法学,执行功能障碍和疾病严重程度上有所不同,这表明临床连续性,而不是不同的PPAOS和PAA实体.
- 三个潜伏的临床维度解释了71%的差异:严重程度 - 异文主义,突出的AOS和突出的脱节性关节炎.
- 严重程度-阿格拉姆马蒂斯组件和基线脱关节/阿格拉姆马蒂斯预测疾病进展加速 (CDR-SB增速更快).
结论:
- PPAOS和PAA可能代表 nfvPPA频谱内的临床连续性.
- 目前的临床表型没有显著改善临床病理相关性,强调需要新的生物标志物和修订的分类系统.
- 疾病的进展是独立预测的因素,包括失联症的严重程度,言语速度,和语法水平.

Higher Mental Functions of the Brain: Language
Language formation and comprehension take place in the dominant hemisphere. The dominant hemisphere is responsible for understanding the meaning of spoken, written, or sign language, as well as the ability to communicate. For most people, the left hemisphere is the dominant one. The right hemisphere, then, gives tone and emotional context to the...
