概括
在健康的成年人中,法布里丁并没有显著改善整体工作记忆 (WM). 然而,它在基线表现较低的个体中增强了WM,这表明治疗WM缺陷的潜力.
科学领域:
- 神经科学是一个神经科学.
- 认知科学 认知科学
- 心理药理学 心理药理学
背景情况:
- 工作记忆 (WM) 对认知至关重要,并且在精神疾病如精神分裂症中经常受到损害.
- 药物重新定位为识别用于认知增强的新型治疗剂提供了一条途径.
- 作为通道阻断剂的fampridine通过基因组引导的WM调节查来确定.
研究的目的:
- 在健康的年轻成年人中研究famppridine在调节工作记忆 (WM) 的疗效.
- 为了评估fampridine对认知功能和皮质刺激性的影响.
主要方法:
- 一个双盲,随机,安慰剂控制的交叉试验在43名健康的年轻成年人中进行.
- 参与者接受了fampridine (10毫克每天两次) 或安慰剂3.5天.
- 工作记忆被评估使用3回任务 (d-prime),休息运动值被测量为次要结果.
主要成果:
- 在所有参与者中,法布里丁对工作记忆的表现没有产生显著的主要影响.
- 与安慰剂相比,在基线较低的工作记忆性能和fampridine管理后更大的改善之间发现了显著的正相关性.
- 普利丁的摄入导致了静止运动值的降低,这表明皮质刺激性增加.
结论:
- 范普里丁显示出增强工作记忆的潜力,特别是在基线认知功能较低的个体中.

Alzheimer's Disease: Treatment
165
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...

Cognitive Enhancers: Cholinesterase Inhibitors and NMDA Receptor Antagonists
98
Cognitive enhancers, also known as "smart drugs," are substances used to enhance memory, mental alertness, and concentration. These can be natural or synthetic and improve cognition in conditions like Alzheimer's disease (AD) and other neurodegenerative diseases. Some common examples include caffeine, amphetamines, methylphenidate, modafinil, arecoline, donepezil, vortioxetine, and piracetam. These enhancers work on the principle of synaptic plasticity and altered circuit function.
