- 精神病学是一个精神病学.
- 放射学 放射学是一门学科.
背景情况:
- 动机失调在精神疾病如精神分裂症,严重抑郁症 (MDD) 和双相情感障碍 (BD) 中很普遍.
- 了解动机的神经支对于这些情况至关重要.
- 有限的研究存在于大脑结构和动机特征之间的关系.
研究的目的:
- 调查精神分裂症,MDD和BD患者的大脑微观结构特征和因果导向之间的关联.
- 利用扩散性曲解成像 (DKI) 探索这些关系.
主要方法:
- 40名患有MDD,36名患有BD,30名患有精神分裂症的患者接受了DKI扫描.
- 参与者完成了通用因果关系导向量表 (GCOS).
- 分析了DKI指数和GCOS子量表.
主要成果:
- 在所有患者群体中,在前额外,轨道前额外和后带带皮层区域的GCOS-自主性定向和平均缩 (MK) 之间观察到显著的正相关性.
- 这种关联在左前额叶皮质中尤为明显,特别是在患有MDD,BD和精神分裂症的女性患者中.
结论:
- 内在动机 (自主导向) 和左前额叶皮层微观结构完整性 (MK) 之间的共同关联存在于精神分裂症,MDD和BD中.
- 这一跨诊断性发现可能为精神病学研究提供一种潜在的新生物标志物.

Biological Causes of Schizophrenia
54
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
566
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...

Psychological and Sociocultural Causes of Schizophrenia
82
Schizophrenia, a complex psychiatric disorder, has been historically misunderstood. Early psychological theories attributed its origins to childhood trauma and unresponsive parenting. However, contemporary research largely rejects these notions, favoring the vulnerability-stress hypothesis. This model proposes that individuals with a genetic predisposition to schizophrenia may develop the disorder following exposure to significant environmental stressors. Notably, studies on high-risk...

Theoretical Approaches to Psychological Disorder
216
The development of psychological disorders, which are characterized by deviant, maladaptive, and personally distressing behaviors, has been explored through several theoretical approaches.
Biological approach
The biological approach posits that internal, organic factors are the primary causes of such disorders. This perspective emphasizes brain structure and function, genetic predispositions, and neurotransmitter imbalances. For example, schizophrenia has been associated with both genetic...

Depressive disorders result from a complex interplay of biological, psychological, and sociocultural factors, each contributing uniquely to the development and persistence of the condition. Understanding these factors provides critical insight into the multifaceted nature of depression.
Biological Factors in Depression
Biological predispositions significantly influence the risk of developing depressive disorders. Genetic studies highlight the role of variations in the serotonin transporter...
