概括

患有冲动控制障碍的帕金森病患者在特定的大脑区域的沟深度减少. 这种深度差异可能作为生物标志物用于识别帕金森病中冲动控制障碍.

科学领域:

神经科学是一个神经科学.
神经学神经学
神经成像是一种神经成像.

背景情况:

冲动控制障碍 (ICD) 是帕金森病 (PD) 中显著的非运动症状.
这些疾病与多巴胺疗法和中皮质临界功能障碍有关.
了解PD中ICD的神经解剖学基础对于诊断和管理至关重要.

研究的目的:

为了研究皮质层深度,皮质厚度和皮质下体积变化在PD患者和没有ICD.
为了识别潜在的神经成像生物标志物用于PD中的ICD.
评估已识别的结构变化的诊断效用.

主要方法:

结构性MRI扫描来自68名PD患者 (30名有ICD,38名没有ICD) 和32名健康对照.
用FreeSurfer软件量化了皮层层深度,皮层厚度和皮层下体积.
进行了统计分析,包括组比较和接收器运行特征 (ROC) 分析.

主要成果:

与没有ICD和健康对照组的PD患者相比,患有ICD的PD患者表现出右额头极和左中圈的深度显著减少.
两组之间在皮层厚度或皮层下体积方面没有发现显著差异.
减少右额头极状深度与ICD症状严重程度有负相关性.
罗克分析表明,右额头极和左中圈的深可以有效地区分带有和没有ICD的PD患者.

结论:

显著的皮质状形态变化,特别是右额头极和左中圈的状深度减少,是患有ICD的PD患者的特征.

Parkinson's Disease: Overview

Parkinson's Disease: Overview

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

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.
Parkinson's Disease is primarily a result of the loss of dopaminergic neurons in the substantia nigra pars compacta. The cornerstone of...

Neural Regulation

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.

Attention-Deficit/Hyperactivity Disorder

Attention-Deficit/Hyperactivity Disorder

Attention-deficit/hyperactivity disorder (ADHD) is a neurodevelopmental disorder characterized by persistent inattention, hyperactivity, and impulsivity. It affects approximately 5-8% of children globally, with around 60-70% of cases persisting into adulthood. ADHD has significant implications for educational attainment, social interactions, and occupational success.
Diagnostic Criteria and Symptoms
To diagnose ADHD, symptoms must manifest before age 12 and be evident across multiple settings....
