概括
帕金森病患者的轻度认知障碍和视觉幻觉都显示出基底前脑缩. 这种缩,特别是在Ch4区域,与这些症状的同时发生有关,支持"胆性表型".
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) 和轻度认知障碍 (MCI) 在帕金森病 (PD) 中很常见.
- 无论是VH还是MCI都与胆基底前脑 (BF) 的缩有关.
- BF次区域完整性与PD中VH和MCI的同时发生之间的具体关系尚不清楚.
研究的目的:
- 调查总和次区域基础前脑 (BF) 容量与轻度认知障碍 (MCI),视觉幻觉 (VH) 的存在以及它们在帕金森病 (PD) 中的同时发生之间的关联.
主要方法:
- 分析了296名PD患者的结构MRI和临床数据.
- 后勤回归模型检查了BF体积 (总体,Ch1-2,Ch3,Ch4,Ch4p) 和症状状态 (MCI,VH,同时发生) 之间的关系.
- 对包括年龄,性别和药物使用在内的混因素进行控制的分析.
主要成果:
- 总体BF,Ch1-2和Ch4体积与PD-MCI的可能性有负相关性,但不是孤立的VH.
- 总的BF和Ch4量与MCI和VH的同时发生有负相关性.
结论:
- 基底前脑缩 (BF),特别是在Ch4核中,与帕金森病 (PD) 中轻度认知障碍 (MCI) 和视觉幻觉 (VH) 的联合存在有关.
- 这一发现支持了"一带一路"的概念.
- 胆固醇的表型 胆固醇的表型
- 在PD. 在PD.
- 1-2体积也与MCI有关,这表明由于其叶连接,它可能发挥作用.

Parkinson's Disease: Overview
1.7K
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...

Parkinson's Disease: Treatment

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.

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.

Alzheimer's Disease: Overview
1.6K
Alzheimer's Disease (AD) is a continually advancing neurodegenerative disorder, distinguished by escalating memory loss, cognitive dysfunction, and dementia. The disease unfolds in three stages: preclinical, mild cognitive impairment (MCI), and dementia. Its onset is insidious, and the progression gradual, with the cause not well explained by other disorders.
The clinical diagnosis of AD hinges on the presence of memory and other cognitive impairments. Biomarkers, such as changes in Aβ...

Positive Symptoms Schizophrenia: Hallucinations and Delusions
461
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.
