medRxiv : the preprint server for health sciences
|September 2, 2025
概括
患有精神病谱系障碍 (PSD) 的个体表现出较薄的视网膜层,特别是光受体,与记忆缺陷有关. 这些结构变化可能反映出影响认知的神经生物学变化.
科学领域:
- 眼科 眼科
- 神经科学
- 精神病学
背景情况:
- 视网膜结构的改变可以作为精神病谱系障碍 (PSD) 和认知功能的生物标志物.
- 需要进行更大规模的,精心控制的研究来调查这些潜在的关联.
研究的目的:
- 与健康对照组 (HC) 相比,研究PSD患者视网膜厚度的差异.
- 探索视网膜厚度与PSD认知表现之间的关联.
- 识别受PSD影响的特定视网膜层及其与认知的关系.
主要方法:
- 使用英国生物库数据进行的嵌套病例对照研究.
- 476名参与者 (PSD和HC) 接受了斑点光学连贯断层扫描 (OCT).
- 反复测量ANCOVA评估了视网膜厚度,控制社会人口统计学,眼部和健康共变量,不包括心脏代谢条件.
主要成果:
- 与HC相比,患有PSD的个体表现出更薄的斑点,状细胞内部和光受体层.
- 较小的光受体层厚度与较差的潜在记忆性能有显著的关联.
- 精神分裂症和双相情感障碍组显示光受体层的变化最明显.
结论:
- 患有PSD的个体表现出突触,质细胞和光受体层的结构变化.
- 眼睛和健康因素,特别是心脏代谢障碍,可能会导致这些视网膜变化.
- 在PSD中的光受体形态变化可能与视觉处理和记忆缺陷背后的神经生物学机制有关.

Psychosis: Pathophysiology of Schizophrenia and Other Psychotic Disorders
945
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...

Negative and Cognitive Symptoms of Schizophrenia
120
Negative symptoms of schizophrenia indicate a reduction or absence of typical behaviors and emotional responses found in healthy individuals, while positive symptoms reflect an excess or distortion of normal functioning.
Negative Symptoms
Negative symptoms of schizophrenia manifest as deficits in normal emotional and behavioral functioning, profoundly impacting daily life. Individuals with schizophrenia often display a flat affect, characterized by a near-total absence of emotional expression,...

Psychological and Sociocultural Causes of Schizophrenia
185
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...

Psychosis and Antipsychotic Drugs: Overview
453
The term "psychosis" refers to a spectrum of mental disorders characterized by abnormal thoughts, perceptions, and behaviors. It can manifest as mood disorders, dementia, delirium with psychotic features, substance-induced psychosis with psychotic features, brief psychotic disorder, delusional disorder, schizoaffective disorder, and schizophrenia. Among all these disorders, schizophrenia is the most common psychotic disorder, affecting 1% of the worldwide population. Psychotic...

Psychosis: Goals of Pharmacotherapy
209
Antipsychotic drugs are a crucial treatment method for acute and chronic psychoses, bipolar illness, and behavioral disorders. The selection of these drugs depends on several factors, including the state of the disease, clinical judgment, possible drug interactions, and the patient's sensitivity to adverse effects. In immediate scenarios, such as delirium and dementia, short-term treatment with low doses of high-potency typical or atypical agents can effectively manage symptom exacerbation.

Schizophrenia is a complex mental health disorder that can manifest with various positive symptoms, including thought, movement, and behavior disorders. These symptoms significantly disrupt cognitive and motor functions, leading to profound effects on an individual's ability to engage with the world.
