概括
加速间歇性甲爆刺激 (iTBS) 与认知训练相结合,在轻度认知障碍患者中改善了认知功能和大脑效率. 这种干预增强了左侧脊侧前额叶皮层的参与,这表明了一种新的治疗方法.
科学领域:
- 神经科学是一个神经科学.
- 认知科学 认知科学
- 神经调节是一种神经调节.
背景情况:
- Amnestic轻度认知障碍 (aMCI) 的特点是记忆力缺陷,并构成阿尔茨海默病的风险.
- 目前对aMCI的干预措施有效性有限,需要新的治疗策略.
- 了解MCI认知衰退背后的神经机制对于开发有效治疗至关重要.

Long-term Potentiation
Long-term potentiation, or LTP, is one of the ways by which synaptic plasticity—changes in the strength of chemical synapses—can occur in the brain. LTP is the process of synaptic strengthening that occurs over time between pre- and postsynaptic neuronal connections. The synaptic strengthening of LTP works in opposition to the synaptic weakening of long-term depression (LTD) and together are the main mechanisms that underlie learning and memory.

Cognitive Enhancers: Cholinesterase Inhibitors and NMDA Receptor Antagonists
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. They...
