概括
氨酸丰富的质瘤失活1 (LGI1) 抗体相关的自身免疫脑炎的认知功能随着治疗而改善,但执行功能障碍往往仍然存在. 年龄较大与LGI1-AE患者的长期结果较差有关.
科学领域:
- 神经学 神经学
- 免疫学 免疫学 免疫学
- 认知神经科学 认知神经科学
背景情况:
- 氨酸丰富的质瘤失活1 (LGI1) 抗体相关的自身免疫脑炎 (AE) 导致认知和行为问题.
- 虽然免疫疗法有助于恢复,但长期的认知缺陷,特别是执行功能障碍,尚未完全理解.
- 这项研究研究了LGI1-AE的长期认知轨迹,重点关注执行功能.
研究的目的:
- 评估LGI1抗体相关的自身免疫脑炎患者的长期认知结果.
- 专门研究免疫治疗后执行功能障碍的持续性和预测因素.
主要方法:
- 对18名LGI1-AE患者的回顾性分析,随访时间中位数为44个月.
- 通过蒙特利尔认知评估 (MoCA) 和其执行功能子尺度 (EIS) 评估认知功能.
- 使用威尔科克森签名等级测试分析了纵向变化;回归分析确定了结果预测因素.
主要成果:
- 治疗后全球认知显著改善 (中位数MoCA为20至24,p=0.001).
- 执行功能和延迟召回也显示出显著的收益 (p=0.001和p=0.024).
- 年轻患者 (≤65岁) 的初始和后续认知和执行分数更好. 最初的MoCA预测了全球认知;最初的EIS和发病时的年龄预测了执行结果.

Cognitive Dissonance

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...

Predicting Reaction Outcomes
10.9K
Kinetics describes the rate and path by which a reaction occurs. In contrast, thermodynamics deals with state functions and describes the properties, behavior, and components of a system. It is not concerned with the path taken by the process and cannot address the rate at which a reaction occurs. Although it does provide information about what can happen during a reaction process, it does not describe the detailed steps of what appears on an atomic or a molecular level. On the other hand,...

Outcomes of Glycolysis
107.3K
Nearly all the energy used by cells comes from the bonds that make up complex organic compounds. These organic compounds are broken down into simpler molecules, such as glucose. As a result, cells extract energy from glucose over many chemical reactions—a process called cellular respiration.
Cellular respiration can occur aerobically (with oxygen) or anaerobically (without oxygen). In the presence of oxygen, cellular respiration starts with glycolysis and continues with pyruvate...

Long-term Depression
33.3K
Long-term depression, or LTD, is one of the ways by which synaptic plasticity—changes in the strength of chemical synapses—can occur in the brain. LTD is the process of synaptic weakening that occurs over time between pre and postsynaptic neuronal connections. The synaptic weakening of LTD works in opposition to synaptic strengthening by long-term potentiation (LTP) and together are the main mechanisms that underlie learning and memory.

Autoimmune Disorders
1.8K
Autoimmune diseases are a group of disorders in which the body's immune system mistakenly attacks its own cells, tissues, and organs. This results from an overactive immune response against substances and tissues normally present in the body. Let's delve into the concept and mechanism of autoimmune diseases from an immune system point of view, explore different causes and examples of such diseases, and discuss potential solutions.

Guidelines for Writing Outcome

When developing expected outcomes for a patient care plan, the nurse should adhere to the following recommendations:
Patient outcomes reflect the patient's response to the goal rather than what the nurse aims to achieve. Terminology should be observable and measurable to avoid the reader's interpretation. The desired outcome should be realistic and achievable in the designated care timeframe. Expected outcomes should align with adjunctive therapies. The outcome should enhance care...
