概括
帕金森病 (PD) 的下体内核深脑刺激 (STN-DBS) 手术可能会损害认知运动控制. 手术后,参与者表现出较慢的冲击延迟和达到反应时间,这表明潜在的长期认知影响.
科学领域:
- 神经科学是一个神经科学.
- 神经学 神经学
- 康复医学 康复医学 康复医学
背景情况:
- 脑下核深度大脑刺激 (STN-DBS) 是对帕金森病 (PD) 的治疗方法.
- 对于STN-DBS对PD患者运动控制的长期认知影响尚不清楚.
- 运动控制的认知方面,如反应时间,对于日常运作至关重要.
研究的目的:
- 研究STN-DBS手术对帕金森病患者认知运动控制的长期影响.
- 为了比较在STN-DBS手术前后的萨卡德延迟和达到反应时间 (RT).
主要方法:
- 一项初步研究评估了PD患者在手术前大约1个月 (OFF药物) 和手术后8个月 (OFF药物和STN-DBS).
- 参与者执行了一个视觉指导的达到任务,以评估saccade延迟并达到RT.
- 运动障碍学会统一的帕金森病评分表 (MDS-UPDRS) 第三部分的分数也被评估.
主要成果:
- 与手术前相比,STN-DBS手术后8个月的萨卡德延迟和达到RT显著增加 (恶化).
- 在手术前和后的评估之间,MDS-UPDRS Part III分数没有显著变化.
- 这些发现表明,STN-DBS后的运动控制对认知方面的不利影响.
结论:
- 在帕金森病患者中,STN-DBS手术可能会导致对认知运动控制的长期有害变化.
- 潜在的促成因素包括长期组织变化和STN-DBS的戒断效应.

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: Overview
472
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...

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.
