概括
改变疾病的治疗方法可以改善脊髓肌肉缩 (SMA) 的运动功能. 然而,神经认知和语言结果需要进一步的表征,许多接受治疗的儿童经历口语和书面语言障碍.
科学领域:
- 神经学 神经学
- 遗传学 是一个遗传学.
- 儿科 儿科 儿科
背景情况:
- 疾病修饰疗法显著改善了脊髓肌肉缩 (SMA) 儿童的运动结果.
- 在接受治疗的儿科SMA人群中,神经认知和语言的发展尚未完全理解.
- 描述这些结果对于全面的患者护理和长期预后至关重要.
研究的目的:
- 为了研究基因确诊的脊髓肌肉缩 (SMA) I-III类型的儿童的神经认知和语言结果,用疾病修饰疗法治疗.
- 确定运动表型严重程度,SMN2基因拷贝数和观察到的神经认知/语言缺陷之间的潜在相关性.
- 为将专业评估纳入SMA患者的常规多学科护理提供信息.
主要方法:
- 一个单一的观察性研究,涉及16名儿童 (年龄为2.6-15.4岁) 具有遗传确认的SMA类型I-III,所有接受疾病修饰疗法.
- 标准化的神经心理评估评估智力能力,执行功能,社会认知和记忆.
- 用口语和书面语言进行口语语言评估,并通过父母报告的问卷来补充.
主要成果:
- 智力功能被保留 (平均智商=102±4),没有观察到智力障碍.
- 执行功能障碍 (例如,抑制,认知灵活性) 在15%的参与者中存在,父母往往没有发现.
- 口语语言障碍影响了73%的个体,影响了语音,词汇和形态组合,在严重的运动表型和较少的SMN2副本中更为常见.
- 在29%的患者中发现了书面语言障碍,即使在那些没有明显的运动障碍的人中也是如此.
结论:
- 虽然智力功能通常保持不变,但在接受治疗的SMA中,特定的神经认知缺陷 (如执行功能障碍) 可能会发生.
- 在接受治疗的SMA人群中,口语和书面语言障碍很普遍,需要密切监测.
- 神经心理学和语音语言评估的常规整合对于早期检测和针对性干预在儿科SMA护理中至关重要.

01:27Language and Cognition
799
Language serves as a bridge between ideas and communication, influencing how individuals perceive and interact with the world. Psychologists have long debated whether language shapes thought or vice versa. This discussion gained grip with Edward Sapir and Benjamin Lee Whorf in the 1940s, who proposed that language determines thought, a concept known as linguistic determinism. They suggested that the vocabulary and structure of a language influence how its speakers think and perceive reality.

1.0K
Cognitive therapy, pioneered by Aaron T. Beck in the 1960s, is a structured approach to addressing psychological distress by focusing on the influence of thoughts on emotions and behaviors. All cognitive therapies involve the basic assumption that human beings have control over their feelings, and that how individuals feel about something depends on how they think about it. Unlike psychoanalytic methods that delve into unconscious processes or humanistic approaches emphasizing...

01:10Higher Mental Functions of the Brain: Language
3.8K
Language is a system of communication that allows the expression of thoughts, ideas, and feelings. The brain processes language in both hemispheres.
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...

Social psychologists have documented that feeling good about ourselves and maintaining positive self-esteem is a powerful motivator of human behavior (Tavris & Aronson, 2008). In the United States, members of the predominant culture typically think very highly of themselves and view themselves as good people who are above average on many desirable traits (Ehrlinger, Gilovich, & Ross, 2005). Often, our behavior, attitudes, and beliefs are affected when we experience a threat to our...
