概括
功能性条纹性异常 (FSA) 显示了精神病的可靠诊断能力. 然而,这种神经成像生物标志物无法预测接受抗精神病治疗的患者的症状改善.
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.
- 医疗成像医学成像
背景情况:
- 生物标志物需要在临床使用中具有可概括性和可靠性.
- 功能性条纹性异常 (FSA) 是精神分裂症的先进神经成像生物标志物,具有潜在的预后性质.
研究的目的:
- 复制FSA的诊断能力,以区分精神病与健康个体.
- 评估FSA的测试-重试和相位编码方向可靠性.
- 评估扫描长度对FSA诊断准确性和可靠性的影响.
- 测试FSA在预测症状改善方面的预后能力.
主要方法:
- 使用曲线下的面积 (AUC) 来测量诊断歧视的接收器操作员特征 (ROC) 曲线分析.
- 类内相关系数 (ICC) 来评估测试-重试和相位编码方向可靠性.
- 对AUC和ICC的不同扫描长度 (2到10分钟) 的分析.
- 在单独的队列中,在12周内基线FSA得分和症状改善之间的相关性分析.
主要成果:
- 对于精神病,FSA表现出良好的至优秀的诊断歧视 (AUC = 75.4%).
- 测试-重试可靠性在ICC = 0.22到0.48之间;相位编码方向可靠性是ICC = 0.51.
- 增加扫描长度提高了诊断分类和可靠性.
- 在12周内,FSA得分与症状改善没有相关性.
结论:
- FSA是一种可泛化和可靠的精神病诊断生物标志物.
- 目前,FSA缺乏预测治疗反应的预后能力.
- 预后生物标志物的未来发展应专注于治疗反应数据.

Psychosis: Pathophysiology of Schizophrenia and Other Psychotic Disorders
662
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...

Biological Causes of Schizophrenia
58
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.
Genetic Factors in Schizophrenia
The genetic basis of schizophrenia is strongly supported by family and twin...

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...
