概括
在多发性硬化症 (MS) 患者中,玛跨交替电流刺激 (tACS) 短暂改善了诸如工作记忆 (WM),信息处理速度 (IPS) 和口头记忆 (VM) 等认知功能.
科学领域:
- 神经科学是一个神经科学.
- 认知神经学 认知神经学
- 神经调节是一种神经调节.
背景情况:
- 多发性硬化症 (MS) 经常会影响工作记忆 (WM),信息处理速度 (IPS) 和口头记忆 (VM).
- 在MS中,这些认知缺陷与神经振荡活动的改变有关.
- 跨交替电流刺激 (tACS) 提供了一种潜在的非侵入性方法来调节大脑节律并解决MS认知障碍.
研究的目的:
- 评估马 (γ) -tACS对MS患者的WM,IPS和VM的即时 (在线) 和延迟 (离线) 影响.
- 使用脑电图 (EEG) 与认知表现一起调查大脑节律的变化.
- 为了将g-tACS效应与假刺激进行比较.
主要方法:
- 36名患有单一领域认知障碍 (WM,IPS或VM) 的多发性硬化患者参与了这项研究.
- 参与者在左背侧前额皮层 (DLPFC) 或前额皮层上接受了g-tACS或假tACS.
- 在多个时间点 (刺激前,刺激期间和刺激后) 进行认知测试 (DSBW,SDMT,RAVLT) 和EEG记录.
主要成果:
- 认知分数 (DSBW,SDMT,RAVLT) 在γ-tACS期间显示过渡性改善,但在假刺激期间没有.
- 患有IPS缺陷的患者在DLPFC γ-tACS.S之后在所有频段的刺激部位表现出降低的光谱功率.
- 脑电图分析显示神经振荡的变化与认知改善相关.
结论:
- 玛 (γ) -tACS在患有MS的个体中提供WM,IPS和VM的临时增强.
- 这些发现支持进一步研究g-tACS作为MS认知功能障碍的非侵入性治疗方法.
- 该研究强调了神经调节技术在管理MS相关认知缺陷方面的潜力.

Cognitive Enhancers: Cholinesterase Inhibitors and NMDA Receptor Antagonists
88
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.

Alzheimer's Disease: Treatment
142
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...
