概括
较短的状硫 (PCS) 长度与帕金森病 (PD) 中的视觉幻觉 (VH) 有关. 这一发现表明PCS可能是PD患者VH倾向的生物标志物.
科学领域:
- 神经科学是一个神经科学.
- 神经学 神经学
- 放射学 放射学是一门学科.
背景情况:
- 视觉幻觉 (VH) 在帕金森病 (PD) 中很普遍,但其潜在机制尚未完全理解.
- 之前的研究表明,听觉幻觉和状硫 (PCS) 长度之间存在联系,可能与现实监测缺陷有关.
- 在了解PD中VH的结构性大脑相关性方面仍然存在差距.
研究的目的:
- 调查帕金森病 (PD) 患者的状硫 (PCS) 长度和视觉幻觉 (VH) 的发生之间的关系.
- 探索PCS长度是否可以作为PD中VH的生物标志物.
- 检查PCS长度,认知功能和PD中的VH之间的潜在关联.
主要方法:
- 65名帕金森病患者被分为具有视觉幻觉 (PDVH) 或没有视觉幻觉 (PDnonVH) 的组,使用迈阿密大学帕金森病幻觉问卷.
- 横突 (PCS) 的长度是从斜T1加权的MRI扫描中测量出来的;总内体积也被计算出来.
- 进行了临床和神经心理测试评估,包括记忆和语义流性测试.
主要成果:
- 与没有VH (PDnonVH) 的患者相比,患有PD和VH (PDVH) 的患者的PCS总长度显著缩短.
- 在PDVH组中也观察到右和左PCS长度的减少.
- PDVH组显示较低的视觉即时和长期记忆得分和更高的空间边界子测试识别得分. 在PDVH组中,语义流与PCS长度正相关.
- 发现减少PCS长度显著增加了PD患者体验VH的可能性.
结论:
- 降低状硫 (PCS) 长度与帕金森病 (PD) 的视觉幻觉 (VH) 有关.
- PCS长度可以作为现实监测机制的神经解剖学生物标志物,以及在PD中对VH的倾向.
- 对PCS形态的进一步研究可以提高我们对PD中VH病理生理学的理解.

Psychosis: Pathophysiology of Schizophrenia and Other Psychotic Disorders
1.0K
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...

Neural Regulation

Digestion begins with a cephalic phase that prepares the digestive system to receive food. When our brain processes visual or olfactory information about food, it triggers impulses in the cranial nerves innervating the salivary glands and stomach to prepare for food.

Parkinson's Disease: Overview
718
Neurodegenerative disorders are progressive diseases that cause irreversible damage and loss to neurons in specific brain areas. Examples of these disorders include Parkinson's disease, Alzheimer's disease, Multiple Sclerosis (MS), and Amyotrophic Lateral Sclerosis (ALS). These disorders share characteristics such as proteinopathies, selective neuronal vulnerability, and a complex interplay between genetic and environmental factors. The primary therapeutic goal for these conditions is...

Biological Causes of Schizophrenia
154
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...

Positive Symptoms Schizophrenia: Hallucinations and Delusions
134
Schizophrenia is a complex psychiatric disorder characterized by a range of symptoms that significantly impact cognition, behavior, and emotional regulation. Among these, the positive symptoms stand out as they involve the addition or exaggeration of normal mental functions, deviating markedly from typical behavior and perception. Hallucinations and delusions are prominent positive symptoms, each profoundly affecting the individual's experience of reality.

Parkinson's Disease: Treatment
389
Neurodegenerative disorders, such as Parkinson's Disease (PD), involve the gradual and irreversible destruction of neurons in particular brain areas. These disorders exhibit standard features like proteinopathies, selective vulnerability of some neurons, and an interaction of intrinsic properties, genetics, and environmental influences in neural injury.
