概括

精神病性双极性障碍 (PBD) 与非精神病性双极性障碍 (NPBD) 相比,显示出严重的前额白质 (WM) 断开连接. 这些发现突出了WM微观结构的差异,并可能有助于区分PBD和精神分裂症 (SZ).

科学领域:

神经成像是一种神经成像.
精神病学是一个精神病学.
白物质的微观结构

背景情况:

在双相情感障碍 (BD) 和精神分裂症 (SZ) 之间存在共享白质 (WM) 异常.
在BD中,特别是关于精神病的WM异质性对于理解BD-SZ边界至关重要.
之前对精神病 (PBD) 和非精神病 (NPBD) 的WM微观结构的研究取得了有限的结果.

研究的目的:

为了研究精神病性双相情感障碍 (PBD) 和非精神病性双相情感障碍 (NPBD) 之间的白质 (WM) 微观结构差异.
探索WM异常在区分PBD与精神分裂症 (SZ) 中的潜在作用.
为了确定受PBD影响的特定WM区域.

主要方法:

扩散张力成像 (DTI) 用于评估WM微观结构.
参与者包括8名PBD患者,8名NPBD患者和22名健康对照人群 (HC).
进行了基于路径的空间统计 (TBSS) 和兴趣区域 (ROI) 分析.

主要成果:

与NPBD相比,PBD在特定的WM通道 (体,冠状腺辐射) 中观察到辐射扩散率 (RD) 的增加.
NPBD显示了与年龄相关的RD显著增加.
与NPBD相比,PBD的RD增加在中年人群中是一致的.

结论:

初步发现表明PBD中严重的额头WM断路,影响半球间和皮层-边缘电路.
这些微观结构的差异可能为在BD-SZ诊断边界的PBD病理生理学提供了洞察力.
需要在更大的样本中进行复制以验证这些发现.

关键词:

Bipolar Disorder

Bipolar Disorder

Bipolar disorder is a chronic mental health condition marked by significant mood fluctuations, including episodes of mania and depression. Elevated energy levels, heightened mood or irritability, impulsive behavior, reduced sleep needs, rapid speech, racing thoughts, inflated self-esteem, and distractibility characterize mania. Individuals with bipolar disorder often alternate between depressive and manic states, with periods of emotional stability lasting an average of six months to a year.

Biological Causes of Schizophrenia

Biological Causes of Schizophrenia

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.

Psychosis: Pathophysiology of Schizophrenia and Other Psychotic Disorders

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...
