概括
耐治疗精神分裂症 (TRS) 涉及与非多巴胺基神经递质系统相关的特定前额外边缘灰质缺陷. 这些发现表明精神分裂症治疗反应不佳的分子基础.
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:
- 精神分裂症的特征是广泛的灰色质量减少,结构共变网络 (SCN) 显示变化的模式,特别是在耐治疗精神分裂症 (TRS) 中.
- 在精神分裂症中治疗耐药性的特定大脑网络和神经递质支仍然不清楚.
研究的目的:
- 研究治疗耐药精神分裂症 (TRS) 患者的结构性共变网络 (SCN) 及其化学架构基础.
- 识别与精神分裂症治疗耐药性相关的独特结构和神经化学基质.
主要方法:
- 使用基于源的形态测量 (SBM) 对来自198个人的MRI数据 (55个TRS,79个非TRS,64个健康对照).
- 绘制了SCN的地图,并使用基于PET的化学架构图谱分析了它们的假定神经递质基础.
主要成果:
- 前额外边缘性SCN显示,与健康对照组 (HC) 和非TRS组相比,TRS中的灰质体积 (GMV) 减少.
- 这种与TRS相关的SCN主要与血清激素,谷氨酸激素,组胺激素和阿片类受体有关.
- 在TRS和非TRS组 (与HC相比) 中,一个具有减少GMV的单独SCN缺乏特定的神经递质协会.
结论:
- 患有TRS的个体表现出明显的前额外边缘结构缺陷,具有独特的非多巴胺基化学架构,超出了一般的GMV减少.
- 这些发现表明精神分裂症治疗耐药性的特定分子和结构基础.
- 这项研究可能有助于开发用于TRS的新药疗法.

Biological Causes of Schizophrenia
509
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.

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...

Attention-Deficit/Hyperactivity Disorder
792
Attention-deficit/hyperactivity disorder (ADHD) is a neurodevelopmental disorder characterized by persistent inattention, hyperactivity, and impulsivity. It affects approximately 5-8% of children globally, with around 60-70% of cases persisting into adulthood. ADHD has significant implications for educational attainment, social interactions, and occupational success.
Diagnostic Criteria and Symptoms
To diagnose ADHD, symptoms must manifest before age 12 and be evident across multiple settings....
