神经成像是一种神经成像.
精神病学是一个精神病学.
认知神经科学认知神经科学

背景情况:

低于值的抑郁症 (StD) 是常见的,也是主要抑郁症的危险因素.
此前对性病脑部异常的研究是有限的,特别是关于前端对称网络 (FPN) 的研究.

研究的目的:

调查性病患者年轻人FPN的结构和功能变化.
使用扩散张力成像 (DTI) 和功能磁共振成像 (fMRI) 来检查FPN变化.

主要方法:

基于路径的空间统计和路径学分析了白质完整性,使用DTI.
使用fMRI评估了功能连接 (FC) 和区域同质性.
网络分析 (中间中心性) 检查了FPN的结构和功能组织.

主要成果:

患有性病的个体体在体中呈现了小分异性变异的降低,并在带膜和近中心叶片中减少了白质通道.
在关键的FPN区域内发现了显著的FC减少,包括带带,中侧上额和前.
观察到前骨的区域同质性变化和中部上额头回中部中心性降低,与抑郁症症状严重程度相关.

结论:

这项研究揭示了前两侧神经网络中显著的结构和功能异常,与下值抑郁相关.

Depression: Overview

Depression: Overview

Depression is a prevalent mental illness marked by persistent sadness and lack of interest in previously enjoyable activities. It can take several forms, including major depression, persistent depressive disorder, and bipolar I and II disorders. Symptoms range from emotional changes like chronic worry to physical changes like sleep disturbances and suicidal thoughts. From a neurobiological perspective, depression is believed to be triggered by abnormalities in the brain's prefrontal cortex,...

Brain Imaging

Brain Imaging

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...
