概括
在先进的多系统性缩 (MSA) 患者中,N-乙-DL-氨酸 (ADLL) 改善了REM睡眠行为障碍,但使步态和平衡恶化,导致早期中止. 需要进一步研究早期MSA阶段的ADLL安全性和有效性.
科学领域:
- 神经学 神经学

- 临床药理学 临床药理学
背景情况:
- 多重系统缩 (MSA) 是一种罕见的,渐进的α-synucleinopathy,治疗选择有限.
- 在α-synucleinopathy中,N-乙-DL-氨酸 (ADLL) 已经显示出对小脑症状和REM睡眠行为障碍 (RBD) 的潜力.
- 在富有同情心的使用下,研究了晚期MSA患者的ADLL.
研究的目的:
- 评估N-乙-DL-氨酸 (ADLL) 在晚期多系统性缩 (MSA) 患者的安全性和有效性.
- 评估ADLL对小脑症状和REM睡眠行为障碍 (RBD) 在MSA的影响.
主要方法:
- 三名患有晚期MSA和严重小脑症状的患者接受了ADLL (TanganilTM) 的治疗,定位为每天5g.
- 患者被监测到小脑症状,步态,平衡和RBD的变化.
- 由于不良事件,治疗被提前中止.
主要成果:
- 两名RBD患者在服用完整剂量的2-3周内报告了症状的减少.
- 这三名患者都经历了 significant 的步态和平衡恶化,导致跌倒和健康下降.

Alzheimer's Disease: Treatment
824
Alzheimer's Disease (AD), a neurodegenerative disorder, is pathologically identified by amyloid plaques and neurofibrillary tangles composed of tau protein. AD pharmacotherapy aims to manage cognitive symptoms, delay disease progression, and treat behavioral symptoms. The treatment is primarily symptomatic and palliative, with no definitive disease-modifying therapy available. Cholinesterase inhibitors, including donepezil (Aricept), rivastigmine (Exelon), and galantamine (Razadyne), are...

Myasthenia Gravis: Overview and Treatment
2.8K
Myasthenia gravis is a neuromuscular transmission disorder characterized by weakness and increased fatigability of skeletal muscles. It is an autoimmune disease affecting approximately one in 2000 people, where antibodies against the α1 subunit of nicotinic acetylcholine receptors are produced.
These antibodies interfere with the function of the nicotinic receptors in three ways: by binding to the receptor and disrupting acetylcholine binding; by causing cross-linking of receptors which...

Parkinson's Disease: Treatment
986
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...
