概括
在精神分裂症患者中,较低的N-甲基-D-酸盐受体 (NMDAR) 亚单元NR1水平可能预测大脑刺激后的认知改善. 外围NR1和NR2可以作为治疗疗效的生物标志物.
科学领域:
- 神经科学是一个神经科学.
- 精神病学是一个精神病学.
- 生物标志物 生物标志物
背景情况:
- 认知功能障碍显著损害了精神分裂症 (SZ) 中的社会功能.
- 在这些认知缺陷中,N-甲基-D-酸盐受体 (NMDAR) 低功能的存在.
- 识别认知干预疗效的生物标志物对于SZ治疗至关重要.
研究的目的:
- 调查外围NMDAR亚单元 (NR1和NR2) 水平与接受认知干预的SZ患者的认知改善之间的关联.
- 评估NR1和NR2作为预测治疗反应的生物标志物的潜力.
主要方法:
- 一项随机对照试验的二次分析,涉及60名SZ患者和30名健康对照 (HCs).
- 患者接受了为期五天的跨直流刺激 (tDCS),针对脊侧前额皮层 (DLPFC) 或后壁皮层 (PPC),或假刺激.
- 周围血液样本在基线,第一周和第二周通过ELISA收集NR1和NR2量化. 在同一时间点评估认知能力.
主要成果:
- 与HC相比,SZ患者的基线NR1度显著低于SZ患者;没有观察到NR2差异.
- 与其他组相比,活跃的PPC组显示出显著的工作记忆的改善.
- 在活跃的PPC组中,基线NR1和NR2水平与第1周的工作记忆改善有负相关性. NR1和NR2水平的变化与工作记忆的改善有关.
结论:
- 周围NR1和NR2水平显示出作为预测SZ患者认知改善的生物标志物的潜力.
- 这些发现支持NMDAR功能障碍在SZ相关认知缺陷中的作用,并突出了潜在的治疗目标.

01:24Working Memory
779
Working memory refers to a combination of components, including short-term memory and attention, that allow an individual to hold information temporarily as we perform cognitive tasks. It is an essential cognitive function that enables the execution of complex tasks such as problem-solving, comprehension, and reasoning. Unlike short-term memory, which simply involves the storage of information for a brief period, working memory involves the active manipulation and processing of this...

01:30Cognitive 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.
