概括

童年虐待 (CM) 与严重抑郁症 (MDD) 有关. 这项研究发现,在有CM病史的MDD患者中,大脑网络和与免疫相关的基因表达存在差异,这表明生物联系.

科学领域:

神经科学是一个神经科学.
遗传学是一个遗传学.
精神病学是一个精神病学.

背景情况:

童年虐待 (CM) 是主要抑郁症 (MDD) 的已知危险因素.
连接CM和MDD的生物机制尚未完全理解.
研究大脑功能和基因表达可能会阐明这些机制.

研究的目的:

检查MDD和CM病史的个体中大脑功能网络的差异.
分析与CM和MDD相关的外周血液转录组学.
为了确定CM,MDD和相关症状联系在一起的生物学途径.

主要方法:

功能磁共振成像 (fMRI) 和基于网络的统计数据被用来分析大脑网络.
采集了血液样本进行转录组分析,并确定了基因共同表达模块.
差异性连接性分析评估了跨组基因共同表达网络的变化.

主要成果:

一个独特的功能网络以下椎回路为中心,在CM (MDD_CM) 的MDD患者,没有CM的MDD患者 (MDD_nCM) 和健康对照者 (HC) 之间有显著差异.
八个基因共同表达模块,富含免疫和代谢途径,在各组中各不相同.
I型干扰素通路与MDD_nCM中的网络干扰相关,而免疫模块与MDD_CM中的睡眠障碍相关.

结论:

受损的下椎功能网络与MDD病理生理学有关.
免疫相关的转录组变化与MDD有关,特别是在童年虐待的背景下.
这些发现突出了潜在的生物学途径,将生命早期的逆境与严重抑郁症联系起来.

Attention-Deficit/Hyperactivity Disorder

Attention-Deficit/Hyperactivity Disorder

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....

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...
