概括
帕金森病 (PD) 患者表现出完整的基本注意力功能. 只有当需要认知过程 (如运动准备) 来解释线索时,才会出现注意力定向的缺陷.
科学领域:
- 神经科学是一个神经科学.
- 认知心理学 认知心理学
- 神经学 神经学
背景情况:
- 帕金森病 (PD) 影响运动和认知功能,包括注意力.
- 之前的研究集中在PD的空间注意力,但提示格式在注意力定向和警报中的作用仍然未被充分探索.
研究的目的:
- 研究外源和内源暗示格式如何影响PD患者的视觉空间注意力.
- 评估注意力定向的好处,重新定向的成本,以及PD中的警报能力.
主要方法:

Parkinson's Disease: Overview
495
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
235
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.

Attention-Deficit/Hyperactivity Disorder
50
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....

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.
