概括
"跳枪"标志有效地识别了等待冲动性在渐进的超核麻-理查德森综合征 (PSP-RS). 这种新的临床症状与PSP-RS患者的特定神经和连接性变化相关.
科学领域:
- 神经科学是一个神经科学.
- 神经学 神经学
- 临床评估 临床评估
背景情况:
- 等待冲动性是一个具有挑战性的症状,用于评估渐进性超核性 - 理查德森综合征 (PSP-RS).
- 核心 accumbens (NAc) 亚区域与等待冲动性的调节有关.
研究的目的:
- 为了研究PSP-RS中的等待冲动性,使用新的"跳枪" (JTG) 标志.
- 为了比较具有和没有JTG标志的PSP-RS患者之间的NAc亚区域的临床特征,神经连接和微观结构变化.
主要方法:
- 七十七名PSP-RS患者被评估为JTG信号,定义为信号前过早的掌声.
- 扩散张力成像被用来分析微观结构变化和NAc子区域之间的连接性.

01:15Parkinson's Disease: Overview
579
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...

283
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.

76
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....
