概括
控制不良的会显示出渐进的脑部变化,包括皮质稀薄和皮质下缩. 瓦尔酸盐可能会在异常性泛性 (IGE) 中提供对这些结构变化的保护.
科学领域:
- 神经成像是一种神经成像.
- 发病学 (Epileptology) 是一个专业的学科.
- 神经学 神经学
背景情况:
- 异形性通用性 (IGE) 常常对治疗有反应,但有些患者经历了持续的发作,尽管药物试验.
- 在控制不良的慢性IGE中,渐进的结构性大脑变化尚未得到充分理解.
- 这项研究调查了早期阶段与慢性IGE中的纵向大脑变化.
研究的目的:
- 为了确定是否控制不良的慢性IGE与渐进的形态学大脑变化有关.
- 将这些变化与早期IGE的变化进行比较.
- 探索氨酸的潜在保护作用,并监测疾病的进展.
主要方法:
- 使用T1加权MRI扫描进行长度病例控制神经成像研究.
- 两个队列:早期IGE和慢性IGE,与匹配的健康对照.
- 在至少12个月的时间内分析皮层厚度,皮层下体积和结构共变性.
主要成果:
- 早期的IGE显示出膜缩;慢性IGE显示出广泛的皮质稀疏和皮下缩 (膜,乳头,).
- 综合性强力-克隆性发作与前额叶皮层稀薄和前中心环结缩相关.
- 光敏IGE与皮皮质加厚有关;氨酸使用与减弱的结构变化有关.
结论:
- 慢性IGE,特别是在持续的全身发作或光敏感性时,显示出显著的渐进性大脑变化.
- 酸可能在缓解这些结构变化的过程中起到保护作用.
- 纵向MRI是跟踪疾病进展和IGE治疗疗效的宝贵工具.

Generalized Hooke's Law
2.7K
The generalized Hooke's Law is a broadened version of Hooke's Law, which extends to all types of stress and in every direction. Consider an isotropic material shaped into a cube subjected to multiaxial loading. In this scenario, normal stresses are exerted along the three coordinate axes. As a result of these stresses, the cubic shape deforms into a rectangular parallelepiped. Despite this deformation, the new shape maintains equal sides, and there is a normal strain in the direction of the...

Generalized Anxiety Disorder
692
Generalized Anxiety Disorder (GAD) is a chronic condition characterized by excessive and uncontrollable worry that persists for at least six months, significantly interfering with daily functioning. Unlike situational anxiety, which arises in response to specific stressors, GAD often occurs without a clear cause. Individuals may experience disproportionate worry about work, health, or relationships. For instance, a person might continuously fear poor health despite normal medical evaluations or...

Social Foundations of Self II: The Generalized Other
259
According to George Herbert Mead, as children progress beyond the game stage, they develop a more comprehensive understanding of societal rules and norms. This cognitive and social development enables them to internalize the expectations of the broader community, refining their ability to regulate behavior.Consistent participation in organized activities is crucial in helping children recognize that their actions are not isolated but contribute to a more significant, interconnected group...

Generalization, Discrimination, and Extinction
1.4K
Generalization, discrimination, and extinction are key concepts in operant conditioning that influence how behaviors are learned and maintained.
Generalization occurs when a behavior reinforced in one context is performed in similar situations. For instance, a student who studies diligently for calculus and receives excellent grades might apply the same study habits to psychology and history, expecting similar results. Generalization shows how learning in one setting can influence behavior in...

Epilepsy and Seizures: Overview
1.3K
Epilepsy is a chronic neurological disease marked by recurrent, unpredictable seizures. These seizures are caused by abnormal electrical discharges in the brain, leading to behavior, sensation, or consciousness alterations. They can also cause transient impairment of awareness, interfering with daily activities.
Various factors can trigger epilepsy, including genetic factors, brain damage, metabolic causes, and unknown etiology. Diagnosis of epilepsy involves electroencephalography (EEG), which...

Tumor Progression
7.4K
Tumor progression is a phenomenon where the pre-formed tumor acquires successive mutations to become clinically more aggressive and malignant. In the 1950s, Foulds first described the stepwise progression of cancer cells through successive stages.
Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...
