概括
网络弹性分析揭示了精神病障碍中不同的大脑组织. 其他特定的精神分裂症谱系和其他精神病障碍 (OSSO) 显示中间弹性,与精神分裂症谱系障碍 (SSD) 不同.
科学领域:
- 神经科学是一个神经科学.
- 精神病学是一个精神病学.
- 网络科学 网络科学
背景情况:
- 精神分裂症谱系障碍 (SSD) 和其他特定的精神分裂症谱系和其他精神病障碍 (OSSO) 呈现出改变的大脑网络拓.
- 了解网络弹性对于区分精神病障碍至关重要.
研究的目的:
- 通过静止状态功能性MRI (rs-fMRI) 调查SSD,OSSO和健康对照 (HC) 的拓特征和网络弹性.
- 探索网络指标,弹性和症状严重程度之间的关联.
主要方法:
- 从77个SSD,86个OSSO和83个HC的rs-fMRI数据进行图形理论分析.
- 评估全球效率,特征路径长度,节点效率,聚类系数和k-shell/k-core弹性.
- 症状严重程度用正负综合征量表 (PANSS) 来衡量.
主要成果:

Biological Causes of Schizophrenia
467
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.

Brain imaging technologies provide critical insights into both the structure and function of the human brain, enabling medical professionals and researchers to diagnose, study, and treat neurological disorders or psychiatric disorders more effectively.
These technologies include computerized axial tomography (CAT or CT scans), positron-emission tomography (PET scans), magnetic resonance imaging (MRI), functional magnetic resonance imaging (fMRI), and Transcranial Magnetic...

Schizophrenia
685
Schizophrenia, a term introduced by Swiss psychiatrist Eugen Bleuler in 1911, describes a severe psychological disorder marked by profound disruptions in attention, thought processes, language, emotion, and interpersonal relationships. The core feature of schizophrenia is psychosis — a state characterized by a fundamental detachment from reality. This disconnection manifests through distorted logic, impaired perception, and atypical behavior, severely affecting the lives of those...

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...
