概括
精神分裂-强迫性并发症 (SOC) 涉及精神分裂症和强迫症症状. 这项研究发现,与精神分裂症 (SCZ) 和强迫症 (OCD) 组相比,SOC患者有共同的认知不灵活性和放大的神经改变.
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.
- 认知科学 认知科学
背景情况:
- 精神分裂-强迫性并发症 (SOC) 涉及精神分裂症 (SCZ) 中的强迫症症状 (OCS),与严重的精神病理和不良预后相关.
- 精神分裂症和强迫症 (OCD) 之间的抑制和认知灵活性共享的认知障碍可能是SOC的基础.
- SOC的神经机制在很大程度上是未知的.
研究的目的:
- 直接比较与抑制和认知灵活性相关的神经激活.
- 调查SOC,SCZ,强迫症和健康对照 (HC) 患者之间的差异.
主要方法:
- 对28名SOC患者,33名SCZ患者,30名强迫症患者和33名HC患者进行了fMRI扫描.
- 参与者执行了一项联合的移动去/不去任务.
- 分析的重点是与转移相关的和与停止相关的神经激活.
主要成果:
- 与HC相比,所有临床组都在特定的大脑区域中表现出较低的转移相关激活;SOC患者的激活明显低于SCZ和OCD患者.
- 与SCZ患者相比,强迫症和SOC患者在左前关节中表现出更大的停止相关过度激活.
- 在行为方面,SOC和SCZ患者在委托和转移任务时比OCD和/或HC患者犯的错误更多.
结论:
- 认知不灵活是精神分裂症,强迫症和SOC的共同特征.
- 精神分裂症和OCS的同时出现似乎放大了神经变化,表明了附加效应.

Obsessive-Compulsive Disorder
480
Obsessive-compulsive disorder (OCD) is a mental health condition characterized by recurrent obsessions, compulsions, or both, which consume significant time and interfere with daily functioning. Obsessions involve persistent, intrusive, and unwanted thoughts, images, or urges that evoke anxiety. Common examples include irrational fears of contamination or harm. Compulsions are repetitive behaviors or mental acts performed to reduce the anxiety caused by obsessions. For instance, individuals...

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...
