概括
双极性障碍 (BD) 亚型表现出明显的白质完整性差异. 双极性疾病I型 (BD-I) 患者比双极性疾病II型 (BD-II) 患者表现出更大的白质干扰,这表明神经生物学表达不同.
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.
- 大脑结构 大脑结构
背景情况:
- 双极性障碍 (BD) 涉及灰质体积 (GMV) 和白质体积 (WM) 的改变.
- 双极性I (BD-I) 和双极性II (BD-II) 障碍亚型之间的明显的大脑结构差异尚未得到充分理解.
研究的目的:
- 研究BD-I,BD-II和健康对照 (HC) 之间的灰质体积 (GMV) 和白质 (WM) 完整性差异.
- 检查这些结构差异与临床/遗传因素之间的关联.
主要方法:
- 使用基于voxel的形态测量和基于通道的空间统计.
- 在73名BD-I,63名BD-II和136名HC参与者中比较了GMV和分数异构性 (FA).
- 回归模型分析了临床和遗传关联.
主要成果:
- 在WM完整性 (FA) 中发现了显著的群体差异,但不是GMV.
- 比BD-II患者,BD-I患者的FA水平较低,特别是在前大脑中.
- 无论是BD-I还是BD-II患者的FA都低于HC,BD-I的减少更广泛.
结论:
- 双极性障碍的亚型可能代表不同程度的神经生物学障碍.
- 白质微观结构的改变从BD-II增加到BD-I.
- 这些微观结构差异与临床或遗传变量没有明确联系.

Bipolar Disorder
67
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.

Mania and Antimanic Drugs: Overview
181
Mania, a psychological condition characterized by elevated mood, increased energy, and reduced sleep need, is part of the bipolar disorder cycle. The exact cause of mania isn't entirely known, but it is thought to be a combination of genetic, environmental, and neurological factors. Bipolar disorder involves alternating manic and depressive episodes. Mood stabilizers like lithium, antipsychotics, and anticonvulsants help manage these episodes. Lithium carbonate is particularly effective as...

Bulimia Nervosa
78
Bulimia nervosa is a complex and severe eating disorder characterized by a cyclical pattern of binge-and-purge eating pattern. It generally involves an episode of binge eating, followed by compensatory behaviors such as vomiting, excessive exercise, laxative use, or fasting, to prevent weight gain. Despite often maintaining a normal weight, individuals with bulimia are intensely preoccupied with their body image and harbor an overwhelming fear of gaining weight. This can contribute to the...

Human Genetics
570
Human genetics provides a profound framework for understanding the interplay between genetic predispositions and human psychology. At the heart of this discipline lies the study of how genes influence physical traits, behaviors, and susceptibility to diseases. Each person carries a unique genetic code that subtly or significantly shapes their psychological and behavioral landscape.
The complex relationship between genetics and psychology is observable through common biological components such...

Biological Causes of Schizophrenia
57
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.
Genetic Factors in Schizophrenia
The genetic basis of schizophrenia is strongly supported by family and twin...

Psychosis: Pathophysiology of Schizophrenia and Other Psychotic Disorders
643
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...
