概括
遗传因素在很大程度上导致叶 (TLE),特别是没有海马硬化症的非损伤性和 mesial TLE. 获得的因素,如长期发烧发作,也在海马硬化症的发展中起作用.
科学领域:
- 神经科学是一个神经科学.
- 遗传学 遗传学 是一个
- 的研究研究.
背景情况:
- 叶 (TLE) 是成年人中最常见的焦点.
- 从历史上看,TLE被认为是获得的,TLE越来越多地显示出遗传影响.
- TLE的亚型,如带有或没有海马硬化症的 mesial TLE,需要进行不同的病因调查.
研究的目的:
- 通过双胞胎模型研究叶不同亚型的遗传贡献.
- 为了比较单胞胎 (MZ) 与双胞胎 (DZ) 双胞胎的TLE一致率.
- 探索与海马硬化症不一致的MZ双胞胎对中获得的差异.
主要方法:
- 使用了经典的双胞胎模型,有80对双胞胎,其中至少有一个双胞胎有TLE.
- 在MZ和DZ双胞胎中分析了TLE亚型 (损伤性,非损伤性, mesial,侧面,非局部) 的一致率.
- 检查了10MZ双胞胎对与海马硬化症的对内差异.
主要成果:
- 与DZ双胞胎 (0/33) 相比,MZ双胞胎 (17/47) 的TLE一致性显著更高,这表明存在遗传成分.
- 由非损伤性TLE驱动的协同性,特别是没有海马硬化症的 mesial TLE (14/22 MZ vs 0/11 DZ).
- 对于病变性或非局部性TLE没有发现遗传贡献. 在海马硬化症中涉及的NF1基因变异和长期发烧发作.
结论:
- 证实了TLE的生殖系遗传成分,在没有海马硬化症的 mesial TLE中最突出.
- 表明在带有海马硬化症的 mesial TLE 中遗传作用较小,而长期发烧发作等获得因素显著.
- 强调TLE亚型的病因异质性,具有明显的遗传和获得的影响.

Biological Causes of Schizophrenia
154
Schizophrenia, a severe psychiatric disorder, arises from a complex interplay of biological factors, including genetic predisposition, structural brain abnormalities, neurotransmitter dysregulation, and developmental irregularities. These factors collectively contribute to the onset and progression of the disorder, which typically manifests in late adolescence or early adulthood.

Epilepsy and Seizures: Overview
293
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...

Genome-wide Association Studies-GWAS
14.4K
Genome-wide association studies or GWAS are used to identify whether common SNPs are associated with certain diseases. Suppose specific SNPs are more frequently observed in individuals with a particular disease than those without the disease. In that case, those SNPs are said to be associated with the disease. Chi-square analysis is performed to check the probability of the allele likely to be associated with the disease.

Schizophrenia is a neurodevelopmental disorder whose origins are rooted in complex genetic components. Despite our burgeoning understanding, the pathophysiology of this disorder remains incompletely deciphered.
Researchers have identified genetic factors that increase susceptibility to schizophrenia, underscoring the intricate interplay between genetics and environment in disease development. At the core of schizophrenia's pathophysiology is excessive dopaminergic neurotransmission within...
