研究人员确定了四个共同的神经解剖学因素,这些因素是精神疾病中灰质变异的基础. 这些因素有助于解释个体差异,并揭示跨诊断亚型,推进神经成像生物标记物的发现.
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.
- 神经成像是一种神经成像.
背景情况:
- 精神疾病具有共同的神经生物学机制,但个体间的异质性使跨诊断研究复杂化.
- 鉴定可靠的神经成像生物标志物是具有挑战性的,因为患者的变化.
- 现有的病例控制设计难以捕捉个体差异的复杂性.
研究的目的:
- 确定共同的神经解剖学差异因子 (ND因子),解释五种精神疾病的灰色物质体积变化.
- 开发一种方法,通过将灰色物质体积表示为ND因子的加权和来保持个体间的变化.
- 探索这些因素在识别跨诊断患者亚型方面的潜力.
主要方法:
- 利用了四个独立的数据集,包括878名患有精神疾病的患者和585名健康对照 (HC).
- 应用了线性加权和模型来表示使用ND因子的个性化灰色物质体积变化.
- 分析了因子组合,以找出与群体水平异常,认知过程,分子签名和连接组数据的关联.
主要成果:
- 确定了四个强大的和可概括的ND因子,这些因子是不同疾病的灰色物质变异的基础.
- 证明了ND因素能够调和个人和群体层面的形态异常.

Biological Causes of Schizophrenia
35
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.

Theoretical Approaches to Psychological Disorder
68
The development of psychological disorders, which are characterized by deviant, maladaptive, and personally distressing behaviors, has been explored through several theoretical approaches.
Biological approach
The biological approach posits that internal, organic factors are the primary causes of such disorders. This perspective emphasizes brain structure and function, genetic predispositions, and neurotransmitter imbalances. For example, schizophrenia has been associated with both genetic...

Psychosis: Pathophysiology of Schizophrenia and Other Psychotic Disorders
382
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...

Human Genetics
522
Human genetics provides a profound framework for understanding the interplay between genetic predispositions and human psychology. At the heart of this discipline lies the study of how genes influence physical traits, behaviors, and susceptibility to diseases. Each person carries a unique genetic code that subtly or significantly shapes their psychological and behavioral landscape.

Diagnostic and Statistical Manual of Mental Disorders (DSM)
35
The Diagnostic and Statistical Manual of Mental Disorders (DSM) serves as the primary classification system for mental health disorders, providing standardized diagnostic criteria for clinicians and researchers. First published by the American Psychiatric Association (APA) in 1952, the DSM has undergone several revisions to reflect evolving psychiatric understanding. The fifth edition, DSM-5, released in 2013, introduced key updates that expanded diagnostic categories and modified diagnostic...
